NEW QUESTION # 62
A customer is experiencing problems with BGP on their AOS-CX network. The users cannot access specific resources on the network, even though they have been assigned the appropriate roles and permissions.
What is the most likely cause of the problem?
- A. The GBP database is corrupted.
- B. The HPE Aruba Networking ClearPass configuration is incorrect.
- C. The GBP tags are not being applied correctly to the user's traffic.
- D. The users are not being assigned the correct GBP classes.
Answer: C
Explanation:
In AOS-CX, Group-Based Policy (GBP) relies on correct tagging of user traffic. If GBP tags are not applied properly, even users with the correct roles and permissions will not be able to access the intended network resources. This makes incorrect tag application the most likely cause of the BGP-related issue described.
NEW QUESTION # 63
Match the AOS-CX switch BGP keepalive and holddown timersto the default.
Answer:
Explanation:
Explanation:
The question requires matching the default BGP keepalive and hold-down timers on AOS-CX switches to their respective values.
* Analysis of Options:
* Keepalive Timer:The keepalive timer determines how often BGP keepalive messages are sent to maintain a session. The default value on AOS-CX switches is 60 seconds.
* Hold-down Timer:The hold-down timer specifies the maximum time a BGP session can remain active without receiving a keepalive or updatemessage before it is considered down. The default value on AOS-CX switches is 180 seconds.
* Why This Mapping is Correct:Per BGP standards (RFC 4271) and HPE Aruba Networking AOS-CX documentation, the default BGP keepalive timer is 60 seconds, and the hold-down timer is 180 seconds (three times the keepalive interval). These timers ensure BGP sessions remain stable while allowing timely detection of peer failures. The AOS-CX implementation adheres to these defaults unless explicitly configured otherwise.
* Relevance to Certification Objectives:
* Routing (16%):Involves designing and troubleshooting BGP routing topologies, including timer configurations.
* Troubleshooting (10%):Includes diagnosing BGP session issues related to timers.

NEW QUESTION # 64
Which issue may becausing the new door locks on the APs to notwork?
- A. AT power to the AP is too much.
- B. BT power to the AP is too much.
- C. AF power to the AP is not enough.
- D. AT power to the AP is notenough.
Answer: C
Explanation:
New PoE-powered door locks, connected via the PoE passthrough port on Aruba APs, are not working. We need to find the likely cause related to PoE power.
* PoE Passthrough:An AP feature where the AP, powered by PoE from a switch, provides PoE power out to another device connected to one of its Ethernet ports.
* Power Budget:The AP must receive enough power from the switch via its PoE input (e.g., 802.3af,
802.3at, 802.3bt) to power itselfandmeet the power demand of the downstream device (the door lock).
* PoE Standards Power (Approx. Available to Device):
* 802.3af (PoE): ~13 Watts
* 802.3at (PoE+): ~25.5 Watts
* 802.3bt (PoE++): 51W (Type 3) or 71W (Type 4)
* Analysis:Modern APs (especially Wi-Fi 6/6E) can consume significant power themselves (>15W or
>25W under load). Standard 802.3af PoE (supplying only ~13W) is often insufficient to power both a modern AP and a downstream PoE device like a door lock. The AP will power up, but won't enable PoE output if its input power budget is insufficient.
* Analysis of Options:
* A, B: Too much power (AT/BT) isn't the issue; devices only draw what they need.
* C: AF power (~13W) received by the AP is very likelynot enoughto power both the AP and the door lock.
* D: AT power (~25.5W)mightbe insufficient if the combined load of the AP and lock exceeds this, but AF being insufficient (C) is a more common limitation.
* Conclusion:Insufficient input power to the AP is the most common reason for PoE passthrough failure.
802.3af (PoE) power is often inadequate.

NEW QUESTION # 65
What is the best practice for using Dynamic Segmentation?
- A. Use UBT to create isolated networks for specific types of devices.
- B. Use LUR to assign roles to devices based on their location and DUR to assign roles to devices based on their user identity.
- C. Use a combination of role-based access and overlay technologies to create a layered security approach
- D. Use Dynamic Segmentation only on devices that are connected to the network via Wi-Fi.
Answer: C
NEW QUESTION # 66
An IT administrator uses AOS-CX switches to send TCP 22 traffic from the switch port to a remote server to analysis. The administrator now wants to save it locally to be downloaded and used later in case the admin changes their mind about the approach to take.
- A. destination cpu
- B. destination tunnel file tshark-pcpap
- C. destination file tshark-pcap
- D. destination flash://my-mirror.pcpap policy Policy_Mirror22
Answer: C
Explanation:
To save mirrored packets locally on an AOS-CX switch for later download and analysis, use the command destination file tshark-pcap. This will save the mirrored traffic in a pcap file, which you can then download from the switch and analyze as needed.
NEW QUESTION # 67
The customer wants to configure ARP inspection on VLAN 6 port 1/1/2 but not on port 1/1/1.
What are the correct commands to establish this?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
arp inspection must be enabled under the VLAN.
Port 1/1/1 is set as trusted, so ARP packets are not inspected.
Port 1/1/2 is set as untrusted, so ARP packets are inspected.
NEW QUESTION # 68
Refer to the exhibit.
A gateway cluster needs to be connected to the VSX-enabled switches where MC-LAG is configured. What is a possible constraint?
- A. The command lacp fallback is missing on the interface lag level.
- B. LLDP needs to be enabled to detect LACP-configured interfaces.
- C. lacp mode active needs to be configured on the gateways when using "static-activate" mode.
- D. LACP is not supported during the initial provisioning and needs to be turned off.
Answer: D
Explanation:
When connecting a gateway cluster to VSX-enabled switches with MC-LAG, LACP cannot be used during the initial provisioning phase (ZTP/OTP). You must use static port-channeling (no LACP) for the first setup. Once provisioning is complete, you can re-enable LACP. This is a documented constraint for initial gateway provisioning with Aruba gateways.
NEW QUESTION # 69
You are tasked with describing VSX to a colleague. Select the three items that are considered best practices for implementing VSX on AOS-CX. (Choose three.)
- A. Allow VLAN 1 on all trunks in order to facilitate ZTP for downstream devices.
- B. Use a direct L3 circuit for the keepalive connection between both nodes.
- C. Adjust MTU on the ISL link to permit transport of jumbo frames if endpoints require it.
- D. Adjust the default keepalive timers to match or exceed the ISL hold interval.
- E. Set a VSX system-mac manually to simplify switch replacement of the primary if required.
- F. Configure all VLANs manually on both the primary and secondary nodes before enabling vsx-sync.
Answer: B,C,E
Explanation:
Setting a manual VSX system-mac ensures consistency and simplifies replacement in case of hardware failure.
Adjusting MTU on the ISL to support jumbo frames is best practice to avoid fragmentation when endpoints use jumbo frames.
Using a direct L3 circuit for keepalive between VSX peers ensures reliability and avoids dependency on intermediate devices.
NEW QUESTION # 70
Which is a best practice for configuringGBP?
- A. Configure GBP classes to have a destination role that is the same as the associated user rote.
- B. Configure GBP classes to have a destination role that is different from theassociated user role.
- C. Use static user roles (SUR) to configure GBP
- D. Use downloadable user roles (DUR) to configure GBP.
Answer: D
Explanation:
The question asks for a best practice when configuring Group-Based Policy (GBP). GBP simplifies policy management by assigning users/devices to roles and defining policies between these roles, often leveraging dynamic assignment from an authentication server.
* GBP Concepts:Policies are typically defined based on source and destination roles. Roles can be assigned statically on the switch or dynamically via an authentication server like ClearPass.
* Analysis of Options:
* A & C: Policies define interactionsbetweenroles (source role to destination role). These roles can be the same (intra-role policy) or different (inter-role policy). Neither option represents a singular
"best practice" for all configurations.
* B: Using Static User Roles (SUR) is possible but less flexible and scalable than dynamic assignment for large or complex environments.
* D: Using Downloadable User Roles (DUR) is generally considered a best practice. DUR allows roles and associated policies (including GBP attributes like GPID) to be centrally defined on an authentication server (e.g., ClearPass) and dynamically assigned to users/devices uponsuccessful authentication. This provides scalability, consistency, and easier management.
* Conclusion:Leveraging Downloadable User Roles (DUR) from a central authentication server like ClearPass is a best practice for implementing scalable and manageable Group-Based Policies.

NEW QUESTION # 71
Refer to the exhibit.
After an initial setup of CX 8325 VSX configuration, the active gateway is set up for SVI 10. For testing purposes, SVI 10 on the sw-agg1 is shut down while traffic from the client connected to Edge-1 is initiated towards the default route.
What is the expected behavior while performing this test?
- A. Traffic is potentially dropped between the client and the destination.
- B. Traffic is dropped and vsx-sync will disable SVI10 on agg-sw2 automatically.
- C. Traffic is forwarded over the ISL without the risk of dropped packets.
- D. Traffic is unaffected and a 50ns failover time is expected for agg-sw2 to start traffic forwarding.
Answer: A
Explanation:
When SVI 10 is shut down on agg-sw1 (the VSX active gateway), traffic destined for the default gateway will not be able to use that SVI. Unless "VSX active forwarding" is enabled, the other VSX peer (agg-sw2) will not start forwarding traffic for that SVI, so packets are likely dropped.
The default failover is not seamless unless you enable active-forwarding or use a redundancy feature for SVI gateways.
NEW QUESTION # 72
Exhibit.
An end-to-end QoS design needs to be Implemented for wired and wireless. What is needed on the LAN side to maintain the correct DSCP tags?
- A. to trust at DSCP-marked packetsin the QoS interior ports
- B. to create a WMM to DSCP mapping on the LAN Edge
- C. to create a custom DSCP mapping as WLAN DSCP values are different
- D. tocreate a WMM la DSCP mapping on the WLAN side
Answer: A
NEW QUESTION # 73
Acme is having BGP issues with its AOS-CX switch and has asked you to helptroubleshoot the issue You have access to the CLI ofthe switch. Which command can you use to begin troubleshooting?
- A. snow buffer | debug
- B. show debug destinations
- C. show run | route destination!
- D. show debug start
Answer: B
Explanation:
The question involves troubleshooting BGP issues on an AOS-CX switch, and the task is to identify the appropriate CLI command to begin the troubleshooting process.
* Analysis of Options:
* Option A (show run | route destination):Incorrect syntax; the show running-config command with a filter is not specific to BGP troubleshooting.
* Option B (show debug start):Incorrect; AOS-CX does not use show debug start for initiating debugging.
* Option C (show buffer | debug):Incorrect; this is not a valid AOS-CX command for BGP troubleshooting.
* Option D:Correct. The show debug destinations command displays the current debug settings, including whether BGP debugging is enabled, which is a critical first step in troubleshooting BGP issues.
* Why Option D is Correct:To troubleshoot BGP issues, the first step is to verify if debugging is enabled for BGP events, as this provides detailed logs of session states, messages, and errors. The show debug destinations command on AOS-CX switches shows which debug types (e.g., BGP) are active and where logs are sent (e.g., console, syslog). If BGP debugging is not enabled, the administrator can enable it using debug bgp to capture relevant information, making this the ideal starting point for BGP troubleshooting.
* Relevance to Certification Objectives:
* Troubleshooting (10%):Involves performing advanced troubleshooting of routing protocols like BGP.
* Routing (16%):Includes diagnosing BGP session and configuration issues.

NEW QUESTION # 74
A client installed 655 APs in a project to upgrade the network in a large public venue. The customer states that they are having issues with the integration with the new sensor system (Bluetooth) that will help the facilities team monitor when the venue is in the use.
What could be the issue?
- A. AP-655 does not have Bluetooth radio
- B. throughput
- C. Bluetooth needs an advanced AP license.
- D. PoE
Answer: A
Explanation:
The issue is that the AP-655 model does not include a built-in Bluetooth radio. Since the customer's integration relies on Bluetooth for the sensor system, the absence of this hardware capability prevents the solution from functioning as intended.
NEW QUESTION # 75
Exhibit.
After Implementing a distributed overlay with distributed anycast gateways, you noticed that toomany ARP packets are being replicated to every access (leaf) switch Which command can you use to optimize the network?
- A. vlan 10 arp-suppression vlan 11 arp-suppression
- B. evpn arp-suppression
- C. interface vlan 10 ip proxy-arp interface vlan 11 ip proxy-arp
- D. evpn ip proxy-arp
Answer: B
Explanation:
In an EVPN VXLAN distributed overlay network, excessive ARP packet replication (flooding) to all leaf switches is observed. We need the command to optimize this.
* EVPN ARP Optimization:EVPN uses its control plane (BGP) to distribute MAC and IP address reachability information. Leaf switches (VTEPs) learn these mappings. To reduce ARP flooding across the VXLAN fabric:
* ARP Suppression:VTEPs intercept ARP requests. If the VTEP already knows the MAC address for the requested IP (learned via EVPN), it can suppress the ARP request, preventing it from being flooded over VXLAN.
* Proxy ARP:VTEPs intercept ARP requests. If the VTEP knows the MAC for the requested IP, it can generate an ARP replyon behalfof the remote host.
* AOS-CX Commands:These features are configured within the EVPN context.
* evpn arp-suppression (B): Enables the ARP suppression feature for EVPN.
* evpn ip proxy-arp (C): Enables the proxy ARP feature for EVPN.
* Options A and D use standard interface/VLAN level arp-suppression or proxy-arp commands, which are not specific to optimizing flooding within the EVPN VXLAN fabric itself.
* Conclusion:To optimize by reducing the replication/flooding of ARP packets across the EVPN VXLAN overlay, enabling evpn arp-suppression (Option B) is the direct command. This leverages the EVPN control plane knowledge to stop unnecessary ARP flooding.

NEW QUESTION # 76
A customer has configured eBGP peering using local AS 65000 with two routers from a CX 6300 VSF stack with thefollowing switch ports:
[ports connecting to router-1 10.10.10.2]
The LAGs are connected lo third-party L2 switches, which are used as a transit network for the remote eBGP routers. To optimise the possible BGP peering issues. The AOS-CX switch Is configured with theglobal settings:
What needs to be done on the AOS_CX switch to enable the bidirectional forwarding with the eBGP peers?
- A. Option D
- B. Option A
- C. Option C
- D. Option B
Answer: D
Explanation:
The goal is to enable Bidirectional Forwarding Detection (BFD) for eBGP neighbors 10.10.10.2 and
10.10.20.2 on the AOS-CX VSF stack (AS 65000). Global BFD settings are already configured. We need the specific commands to link BFD state to the BGP neighbor relationship.
* BFD for BGP Configuration:Requires enabling the fall-over bfd parameter for the specific neighbor within the router bgp <asn> configuration hierarchy.
* Analyzing the Options (New Image):
* Option 1 (Top):
router bgp 65000
address-family ipv4 unicast
neighbor 10.10.10.2 fall-over bfd
neighbor 10.10.20.2 fall-over bfd
This enables BFD specifically within the ipv4 unicast address family context for both neighbors. This is a valid configuration location.
* Option 2 (Second):
router bgp 65000
neighbor 10.10.10.2 fall-over bfd
neighbor 10.10.20.2 fall-over bfd
This enables BFD directly under the main neighbor <ip> configuration lines within router bgp 65000. This typically applies BFD to all address families configured for that neighbor relationship (including IPv4 unicast). This is also a valid and common configuration location.
* Option 3 (Third):
int 1/1/1-1/1/2, 2/1/1-2/1/2
fall-over-bfd
Incorrect. Applies BFD configuration under an interface range context, which is not how BFD is linked to BGP sessions.
* Option 4 (Bottom):
interface lag1-2
fall-over bfd
Incorrect. Applies BFD configuration under an interface LAG range context, which is not how BFD is linked to BGP sessions.
* Comparing Valid Options (1 vs 2):Both Option 1 and Option 2 correctly use the fall-over bfd command under router bgp. Option 1 provides per-address-family granularity, while Option 2 applies it to the neighbor generally. Without a specific requirement to enable BFDonlyfor IPv4, applying it at the neighbor level (Option 2) is often simpler and sufficient. Both achieve the goal for the required IPv4 peering. In many documentation examples, the configuration is shown at the neighbor level unless per- AF control is explicitly needed.
* Conclusion:Both Option 1 and Option 2 show valid configuration methods. Option 2 is arguably slightly more common/general when BFD is desired for the overall neighbor relationship.

NEW QUESTION # 77
Two CX 8325 switches are configured as a cluster using VSX for the coreroleand two CX 6300M in VSF for theaggregation role. When a minor software upgrade is issued on the switches, what isthe method to achieve a hitlessupgrade with the aggregation switches?
- A. ISSU update-software initiates the upgrade first on the primary switch, followed by the secondary.
- B. ISSU update-software initiates the upgrade first on thesecondary switch, Followed by theprimary.
- C. VSF update-software initiates thesoftware upgrade first on the primary switch. followed by the secondary.
- D. VSF update-software initiates the software Upgrade first on the secondary switch, followed by the primary.
Answer: D
Explanation:
The question involves a minor software upgrade on a VSF (Virtual Switching Framework) stack of CX
6300M switches in the aggregation role, with CX 8325 switches in a VSX cluster as the core. The task is to identify the method for a hitless upgrade on the aggregation switches.
* Analysis of Options:
* Option A:Correct. VSF upgrades start with the secondary switch, followed by the primary, to ensure continuous operation without traffic disruption.
* Option B:Incorrect. In-Service Software Upgrade (ISSU) is used for VSX, not VSF, and follows a different process.
* Option C:Incorrect. Upgrading the primary switch first in VSF risks disrupting control plane operations.
* Option D:Incorrect. ISSU is not applicable to VSF upgrades.
* Why Option A is Correct:In a VSF stack, the update-software command initiates a rolling upgrade, starting with the secondary (standby) switch to ensure the primary (commander) continues handling traffic. Once the secondary is upgraded and rejoins the stack, the primary is upgraded, maintaining hitless operation. This process leverages VSF's ability to keep member switches active during upgrades, minimizing downtime. The CX 6300M's VSF implementation supports this hitless upgrade mechanism, as per HPE Aruba Networking documentation.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Designing and troubleshooting VSF for high availability and hitless upgrades.
* Troubleshooting (10%):Ensuring minimal disruption during software upgrades in campus networks.

NEW QUESTION # 78
You see the output unknown the first time you in the command, but the next time you see the following information displayed.
What aresome things you could took at in the switch to troubleshootthe issue? (Select two.)
- A. diag cable 1/1/X
- B. diag interface 1/VX transceiver all
- C. diag cable-diagnostic 1/1/X
- D. diag interface transceiver al
- E. diag 1/1/X transceiver all
Answer: C,E
Explanation:
The question involves troubleshooting an issue where the command output is initially unknown, but subsequent executions show diagnostic information for an interface (1/1/X). The task is to identify appropriate diagnostic commands to troubleshoot the issue.
* Analysis of Options:
* Option A (diag interface transceiver al):Incorrect syntax; "al" is not a valid parameter.
* Option B (diag interface 1/VX transceiver all):Incorrect syntax; "1/VX" is not a valid interface format.
* Option C (diag cable-diagnostic 1/1/X):Correct. This command runs a cable diagnostic test (TDR) on interface 1/1/X to check for cable faults, such as opens or shorts.
* Option D (diag cable 1/1/X):Incorrect; "diag cable" is not a valid AOS-CX command.
* Option E (diag 1/1/X transceiver all):Correct. This command displays detailed transceiver information, including status, errors, and signal quality, useful for diagnosing interface issues.
* Why C and E are Correct:The diag cable-diagnostic 1/1/X command is used to perform TDR tests to identify cable faults, which could cause connectivity issues. The diag 1/1/X transceiver all command provides detailed transceiver diagnostics, such as power levels, errors, or hardware issues, helping pinpoint problems with the interface or connected device. These commands align with AOS-CX troubleshooting workflows for physical layer issues.
* Relevance to Certification Objectives:
* Troubleshooting (10%):Involves using diagnostic commands to troubleshoot campus network issues.
* Connectivity (9%):Includes identifying problem areas in device deployment, such as cabling or transceiver issues.

NEW QUESTION # 79
You are implementing a network using Zero-Touch Provisioning (ZTP) to deploy the gateways.
What are two requirements for the connection to the switchport? (Choose two.)
- A. The gateway needs to be provided an IP address through DHCP
- B. The switchport needs to be configured with IP address 172.16.0.254
- C. Jumbo frames must be enabled
- D. You must use port GE 0/0/1 on the gateway
- E. The switchport needs to be untagged with Internet access
Answer: A,E
Explanation:
For Zero-Touch Provisioning (ZTP), the gateway must connect to a switchport with untagged Internet access so it can reach Aruba Central or the provisioning server. Additionally, the gateway requires an IP address via DHCP, which provides the necessary network configuration (IP, DNS, default gateway, and optionally ZTP server URL). No specific physical port, static IP, or jumbo frame configuration is required.
NEW QUESTION # 80
AnOSPF router has teamed a path to an external network oy both an El and an E2 advertisement, both routes having the same path cost. Which path -will the router prefer?
- A. The router will prefer the E2 path.
- B. The router will prefer the E1 path.
- C. Both routes will be suppressed until the path conflict has been resolved.
- D. The router will use both paths equally by means ofECMP
Answer: B
Explanation:
The question involves an OSPF router receiving both an E1 (External Type 1) and an E2 (External Type 2) advertisement for an external network with the same path cost. The task is to determine which path the router will prefer.
* Analysis of Options:
* Option A (ECMP):Equal-Cost Multi-Path (ECMP) is used when multiple paths have the same total cost, but E1 and E2 routes have different metric calculations, so ECMP does not apply here.
* Option B (Prefer E2):Incorrect, as E2 routes are preferred only when E1 routes are not present or have a higher total cost.
* Option C (Suppressed):OSPF does not suppress routes due to path conflicts; it selects the best path based on metrics.
* Option D (Prefer E1):Correct. OSPF prefers E1 routes over E2 routes because E1 routes include the internal cost to the ASBR (Autonomous System Boundary Router) plus the external cost, providing a more accurate total cost.
* Why Option D is Correct:In OSPF, external routes are advertised as E1 or E2. E1 routes include both the external cost (advertised by the ASBR) and the internal cost to reach the ASBR, making them more precise for path selection. E2 routes only consider the external cost and are the default for redistributed routes unless explicitly configured as E1. When an OSPF router receives both E1 and E2 routes with the same external cost, it prefers the E1 route because it accounts for the total path cost, including internal network topology. This is per OSPF standards (RFC 2328).
* Relevance to Certification Objectives:
* Routing (16%):Involves designing and troubleshooting OSPF routing topologies, including external route types (E1 vs. E2).
* Troubleshooting (10%):Includes analyzing OSPF path selection to resolve routing issues.

NEW QUESTION # 82
Refer to the four numborod slops in the exhibit.
Which action is the fourthstep in applying a role-to-role ACL on thetraffic from mobile device M1 to roleH2?
- A. The AP forwards the packet from M1 to gateway 1.
- B. Switch A1 determines the destination role based on destination MAC or destination IP and enforces role-to-role ACLs.
- C. Gateway 1 forwards thetraffic over the sialic VXLAN tunnel to the edge switch; this packet carries the Group Policy ID corresponding to the role ofM1.
- D. The edge switch acts as the intermediate node and transfers the Group Policy ID over static VXLAN to dynamic VXLAN tunnel and forwards the packet to switch Al.
Answer: B
Explanation:
The question asks for the fourth step in applying a role-to-role ACL on traffic from a mobile device (M1) to a role (H2) in a network using Dynamic Segmentation with VXLAN. This follows question 17, which identified the first step as the AP forwarding the packet to the gateway.
* Analysis of Options:
* Option A:Correct. The fourth step involves the destination switch (Switch A1) determining the destination role (H2) based on the destination MAC or IP address and applying the role-to-role ACL to permit or deny the traffic.
* Option B:Describes an earlier step (likely second or third) where the gateway forwards traffic over a VXLAN tunnel.
* Option C:Describes the first step, as identified in question 17.
* Option D:Describes an intermediate step (likely third) where the edge switch transfers the Group Policy ID over VXLAN.
* Why Option A is Correct:In HPE Aruba Networking's Dynamic Segmentation architecture, the traffic flow for role-based ACLs in a VXLAN environment follows these steps:
* The AP forwards the packet from M1 to the gateway (question 17).
* The gateway assigns the source role (M1's role) and forwards the packet over a VXLAN tunnel with the Group Policy ID.
* The edge switch transfers the Group Policy ID to the destination switch (A1) via VXLAN.
* Switch A1 determines the destination role (H2) based on the destination MAC or IP address and enforces the role-to-role ACL, as defined in the Group-Based Policy (GBP).
The fourth step is critical for policy enforcement, ensuring that traffic complies with the security policies defined between the source and destination roles, providing secure network segmentation.
* Relevance to Certification Objectives:
* Security (10%):Designing and troubleshooting role-based security policies in customer networks.
* Switching (19%):Implementing Layer 2/3 interconnection technologies like VXLAN for policy enforcement.
* WLAN (9%):Troubleshooting wireless traffic flows in Dynamic Segmentation.

NEW QUESTION # 83
An IT administrator uses AOS-CX switches to send TCP 22 trafficfrom the switch port to a remoteserver for analysis. The administrator now wants to save it locally tobedownloaded and used later in case the admin changes their mind about the approach to take.
- A. destination cpu
- B. destination file tshatk-pcap
- C. destination tunnel file tshark-pcpap
- D. destination flash:/.'my-mirror.pcnap policy Policy Minor22
Answer: B
Explanation:
The question involves an AOS-CX switch administrator using a packet capture (e.g., tshark) to monitor TCP port 22 traffic and wanting to save it locally for later download, instead of sending it to a remote server.
* Analysis of Options:
* Option A:Correct. The destination file tshark-pcap command specifies that the packet capture output is saved to a local file (e.g., tshark-pcap) on the switch's flash storage.
* Option B:Incorrect. destination tunnel file tshark-pcpap is not a valid AOS-CX command for local storage.
* Option C:Incorrect. destination cpu is not relevant for saving packet captures; it may refer to CPU-based monitoring.
* Option D:Incorrect. destination flash:/.'my-mirror.pcnap policy Policy Minor22 has invalid syntax and does not align with packet capture storage.
* Why Option A is Correct:In AOS-CX, packet captures can be configured using the monitor command (e.g., monitor session 1 source interface 1/1/1 destination file tshark-pcap). The destination file tshark- pcap option saves the captured packets (e.g., TCP port 22 traffic) to a local file on the switch's flash storage, which can be downloaded later via SCP, SFTP, or the Web UI. This meets the administrator's requirement to store the capture locally for future analysis, aligning with AOS-CX's packet capture capabilities.
* Relevance to Certification Objectives:
* Troubleshooting (10%):Performing advanced troubleshooting using packet captures.
* Performance Optimization (6%):Analyzing network traffic for performance issues.
* Connectivity (9%):Diagnosing connectivity issues with monitoring tools.
