Check Point Certified VSX Specialist (CCVS) is a certification program that offers knowledge and skills to configure, implement, manage, and troubleshoot VSX solutions. VSX technology is an advanced virtual system that enables multiple virtual firewall instances to be managed as a single system. The CCVS certification exam tests the candidates' knowledge and skills in configuring and managing the VSX environment.
NEW QUESTION # 55
How can you generate a diagnostic snapshot of a VSX Gateway?
- A. cpview collect
- B. cpinfo -o
- C. vsx_util diag
- D. collect_system_snapshot
Answer: B
Explanation:
cpinfo -o generates a complete system diagnostic snapshot, which includes all VSX configurations, kernel parameters, and logs. This is used during support cases or deep troubleshooting efforts.
NEW QUESTION # 56
What command helps identify the cause of dropped traffic in a Virtual System?
- A. dropwatch
- B. fw monitor -p all
- C. tcpdump -nn -i any
- D. fw ctl zdebug drop
Answer: D
Explanation:
fw ctl zdebug drop provides real-time visibility into why packets are being dropped, showing kernel-level decisions and rule evaluations. This is crucial for diagnosing drops due to policy misconfiguration or other inspection layers.
NEW QUESTION # 57
What is the purpose of vsx_util upgrade?
- A. Upgrade SmartConsole objects
- B. Download policy packages
- C. Migrate VSX configurations between versions
- D. Switch cluster members
Answer: C
Explanation:
The vsx_util upgrade command facilitates the migration of VSX configuration data when upgrading software versions. It ensures that VS and gateway definitions are properly backed up, upgraded, and restored in the target environment.
NEW QUESTION # 58
Which of the following commands can be used to monitor per-VS traffic statistics? (Choose two)
- A. vsx stat
- B. SmartView Monitor
- C. vsx_monitor
- D. cpview -vs
Answer: B,D
Explanation:
Both cpview -vs (run from the CLI) and SmartView Monitor (GUI) allow real-time monitoring of per-VS metrics such as bandwidth, CPU, memory, and connection count. These tools help diagnose issues and track performance trends.
NEW QUESTION # 59
Which of the following are limitations of VSX Gateway Clustering compared to physical clusters?
(Choose two)
- A. Requires dedicated sync interface
- B. More complex configuration
- C. Requires centralized management
- D. Cannot perform policy inspection
Answer: B,C
Explanation:
VSX clusters typically require more complex configuration due to their multi-tenant nature. They also rely heavily on centralized management (SmartConsole, VSX provisioning tools), whereas physical clusters can be managed more directly.
NEW QUESTION # 60
Which of the following could cause asymmetrical routing in a VSX environment? (Choose two)
- A. Unbalanced ClusterXL sync
- B. Duplicate MAC addresses on VLAN interfaces
- C. Misconfigured static routes in a VS
- D. Inconsistent route redistribution in dynamic routing
Answer: C,D
Explanation:
Incorrect static routes and improper redistribution between routing protocols in dynamic routing setups can cause asymmetrical paths. This may lead to dropped connections or failure of stateful inspection due to invalid session paths.
NEW QUESTION # 61
What is the primary use of the vsx_util delete command?
- A. Remove VSX objects from the gateway and management
- B. Uninstall Gaia OS
- C. Reset all policies
- D. Convert gateway back to standalone
Answer: A
Explanation:
vsx_util delete removes a Virtual System or other VSX object, including associated interface and routing configurations. It must be used carefully, as deleted objects cannot be recovered once committed.
NEW QUESTION # 62
In a VSX cluster, how is failover determined for each Virtual System?
- A. Independently per VS using VSLS
- B. By physical interface status
- C. Entire cluster fails over as a unit
- D. By gateway CPU usage
Answer: A
Explanation:
With VSLS, each Virtual System in a VSX cluster has its own independent failover logic. This means different VSs can run on different members, optimizing performance and ensuring better fault isolation.
NEW QUESTION # 63
What is the output of the fw vsx stat -v command?
- A. Detailed VS interface, CPU, and memory status
- B. Firewall log summary
- C. Cluster statistics per VS
- D. List of NAT rules per VS
Answer: A
Explanation:
fw vsx stat -v provides verbose output with detailed status of all Virtual Systems on the gateway, including interface mappings, CPU utilization, and memory statistics, making it useful for capacity planning and troubleshooting.
NEW QUESTION # 64
Which features allow traffic inspection to scale with multiple VSs? (Choose two)
- A. cpconfig
- B. SmartEvent
- C. CoreXL
- D. SecureXL
Answer: C,D
Explanation:
CoreXL and SecureXL enhance performance by distributing packet processing across multiple cores and accelerating traffic via fast path mechanisms. These technologies are essential in high- throughput VSX environments for optimal performance.
NEW QUESTION # 65
Which commands help trace packet flow through inspection chains for a specific Virtual System?
(Choose two)
- A. vsenv followed by fw ctl zdebug + drop
- B. fw monitor
- C. netstat -p
- D. fw ctl conn -s
Answer: A,B
Explanation:
fw monitor and fw ctl zdebug (run after entering the appropriate VS context) are used to trace packet movement and detect drops or misrouting. These tools are critical in resolving traffic flow and inspection chain issues.
NEW QUESTION # 66
Which of the following statements about traffic flow in a VSX environment is correct?
- A. Traffic between VSs always goes through external interfaces
- B. All VSs share one IP stack
- C. Virtual Switches or Routers direct internal VS-to-VS traffic
- D. VS0 handles inter-VS traffic routing
Answer: C
Explanation:
Virtual Switches or Routers are responsible for directing traffic between Virtual Systems. These internal components enable isolated routing or switching without involving external interfaces.
NEW QUESTION # 67
Which component maintains session synchronization in both VSX and physical clusters?
- A. Management server
- B. Virtual Router
- C. Sync interface between cluster members
- D. Gaia Portal
Answer: C
Explanation:
A dedicated sync interface is used to replicate session and state data between cluster members in both physical and VSX deployments. This ensures that failover occurs without losing existing connections or session information.
NEW QUESTION # 68
Which command shows current routing tables inside a Virtual System?
- A. netstat -nr
- B. route show
- C. vsx routeview
- D. vsenv then ip route show
Answer: D
Explanation:
To view the routing table for a specific VS, enter its context using vsenv , then run ip route show.
This ensures you're retrieving routing information from the correct namespace associated with that VS.
NEW QUESTION # 69
You need to analyze traffic between two VSs connected to a Virtual Switch.
What is the correct method? (Choose two)
- A. Monitor traffic from the physical interface
- B. Use SmartView Monitor to observe inter-VS traffic
- C. Run tcpdump in VS0
- D. Use vsenv followed by tcpdump
Answer: B,D
Explanation:
By entering the VS context using vsenv , you can capture traffic using tcpdump. Alternatively, SmartView Monitor provides GUI-based traffic insights between VSs connected through a Virtual Switch or Router.
