The recovery time objective (RTO) is the maximum tolerable length of time that a computer, system, network or application can be down after a failure or disaster occurs. This does nothing to help with CPU utilization. Load balancing does this.
NEW QUESTION # 403
Which of the following devices Is used to configure and centrally manage access points Installed at different locations?
- A. VPN concentrator
- B. Load balancer
- C. Wireless controller
- D. Proxy server
Answer: C
Explanation:
Explanation
Access points (APs) can be configured and centrally managed using a wireless LAN controller (WLC). A WLC is a device that connects to multiple APs and provides centralized management and control of those APs. The WLC can be used to configure settings such as wireless network parameters, security settings, and quality of service (QoS) policies. Additionally, the WLC can be used to monitor the status of connected APs, track client connections, and gather statistics on network usage. Some vendors such as Cisco, Aruba, Ruckus, etc. provide wireless LAN controllers as part of their wireless networking solutions.
NEW QUESTION # 404
Users in a remote office report that corporate web server pages are taking a long time to load, whereas users in the main corporate office do not have any issues. Which of the following is the best metric for a network administrator to check?
- A. Server interface CRC errors
- B. Hop-by-hop network latency
- C. Jitter across the network
- D. Server NetFlow data
Answer: B
Explanation:
Explanation
The best metric for a network administrator to check is hop-by-hop network latency. This is because network latency is the time it takes for a packet to travel from the source to the destination, and it affects the loading speed of web pages. Hop-by-hop network latency measures the latency between each pair of routers or switches along the network path, and it can help identify where the delay is occurring. By checking the hop-by-hop network latency, the network administrator can determine if the problem is caused by a slow or congested link, a misconfigured or faulty device, or a routing issue.
Jitter is the variation in latency over time, and it affects the quality of voice and video applications. Jitter does not directly affect the loading speed of web pages, and it is not a useful metric for troubleshooting this issue.
Server interface CRC errors are errors that occur when the cyclic redundancy check (CRC) of a packet does not match the expected value, indicating data corruption. Server interface CRC errors can affect the reliability and integrity of data transmission, and they can be caused by faulty cables, connectors, or interfaces. Server interface CRC errors do not necessarily affect the loading speed of web pages, unless they are severe enough to cause retransmissions or packet loss.
Server NetFlow data is data that is collected and analyzed by the NetFlow protocol, which monitors and reports on network traffic flows. Server NetFlow data can provide information on the volume, type, and direction of traffic that is sent or received by the server, as well as the source and destination IP addresses, ports, and protocols. Server NetFlow data can help identify network usage patterns, trends, and anomalies, but it does not measure the latency or performance of the network.

- A. Shoulder surfing
- B. Tailgating
- C. Dumpster diving
- D. Phishing
Answer: A
Explanation:
Shoulder surfing is the social engineering attack where an attacker watches a user log in to a corporate system and writes down the user's log-in credentials. Social engineering is a type of attack that exploits human psychology and behavior to manipulate or trick people into revealing sensitive information or performing malicious actions. Shoulder surfing is a form of social engineering that involves observing or eavesdropping on someone's screen, keyboard, or paper documents to obtain confidential information such as passwords, PINs, or credit card numbers. Shoulder surfing can be done in person or remotely using cameras or other devices. Shoulder surfing can be prevented by using privacy filters, locking screens, shielding keyboards, or being aware of one's surroundings.

NEW QUESTION # 408
Which of the following objectives does an evil twin achieve?
- A. DNS poisoning
- B. ARP spoofing
- C. Denial of service
- D. Log-in credentials
Answer: D
Explanation:
The objective that an evil twin achieves is log-in credentials. An evil twin is a type of rogue access point that mimics a legitimate wireless network by using the same SSID, encryption, and authentication methods. An evil twin can trick unsuspecting users into connecting to it instead of the real network, and then capture their log-in credentials or other sensitive dat a. An evil twin can also perform man-in-the-middle attacks, redirecting or modifying the user's traffic.

NEW QUESTION # 409
A network technician is investigating an IP phone that does not register in the VoIP system Although it received an IP address, it did not receive the necessary DHCP options The information that is needed for the registration is distributes by the OHCP scope All other IP phones are working properly. Which of the following does the technician need to verify?
- A. VLAN mismatch
- B. Transceiver mismatch
- C. DHCP exhaustion
- D. Latency
Answer: A
Explanation:
Explanation
A VLAN mismatch is the most likely reason why an IP phone does not receive the necessary DHCP options for registration. A VLAN mismatch occurs when a device is connected to a switch port that belongs to a different VLAN than the device's intended VLAN. This can cause communication problems or prevent access to network resources. For example, if an IP phone is connected to a switch port that belongs to the data VLAN instead of the voice VLAN, it may not receive the DHCP options that contain information such as the TFTP server address, the NTP server address, or the default gateway address for the voice VLAN. These DHCP options are essential for the IP phone to register with the VoIP system and function properly. References:

NEW QUESTION # 413
During the troubleshooting of an E1 line, the point-to-point link on the core router was accidentally unplugged and left unconnected for several hours. However, the network management team was not notified. Which of the following could have been configured to allow early detection and possible resolution of the issue?
- A. OID
- B. MIB
- C. Baselines
- D. Traps
Answer: D
Explanation:
Traps are a mechanism for network devices to send unsolicited notifications of events or alarms to a management system. They can be configured to notify the network management team of specific events, such as the unplugging of a point-to-point link on a core router. This feature allows early detection and possible resolution of issues.
MIB (Management Information Base) is a database of information that describes the management data of a device. OID (Object Identifier) is a unique identifier used to identify managed objects in the MIB.
Baselines are a standard set of measurements used to establish normal network behavior, and they are used to compare current network activity against. Baselines can be used to detect abnormal behavior, but they are not as effective as traps for early detection of specific events.

- A. MAC flooding
- B. Denial-of-service
- C. ARP poisoning
- D. On-path
Answer: B
Explanation:
Explanation
A denial-of-service (DoS) attack is an example of an attack where an attacker sends more connection requests than a server can handle, causing the server to crash. A DoS attack is a type of cyberattack that aims to disrupt the normal functioning of a network service or resource by overwhelming it with excessive or malformed traffic. A DoS attack can prevent legitimate users from accessing the service or resource, resulting in degraded performance, unavailability, or data loss. A DoS attack can target various network layers, protocols, or components, such as servers, routers, firewalls, or applications.

- C. Replace the Cat 5 patch cable with a Cat 6 cable
- D. Disable MDIX on the switchport and reboot the server.
- E. Reset the switchport configuration.
Answer: C
Explanation:
Explanation
"Bad cables, incorrect pinouts, or bent pins: Faulty cables (with electrical characteristics preventing successful transmission) or faulty connectors (which do not properly make connections) can prevent successful data transmission at Layer 1. A bad cable could simply be an incorrect category of cable being used for a specific purpose. For example, using a Cat 5 cable (instead of a Cat 6 or higher cable) to connect two 1000BASE-TX devices would result in data corruption. Bent pins in a connector or incorrect pinouts could also cause data to become corrupted."
