NEW QUESTION # 79
Which of the following commands can be used to monitor per-VS traffic statistics? (Choose two)
- A. SmartView Monitor
- B. vsx_monitor
- C. vsx stat
- D. cpview -vs
Answer: A,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 # 80
If a specific VS experiences high CPU, which steps help isolate the cause? (Choose two)
- A. Check SecureXL status using fwaccel stat
- B. Analyze connections using fw tab
- C. Reboot the VS
- D. Use cpview to view per-VS CPU metrics
Answer: A,D
Explanation:
High CPU in a VS may result from unaccelerated traffic or excessive session handling. Using cpview to identify which VS is consuming CPU, and checking whether SecureXL is functioning properly using fwaccel stat, helps in root cause analysis.
NEW QUESTION # 81
Which tool should be used to monitor per-VS interface throughput and connection count?
- A. netstat -i
- B. ifconfig
- C. cpview
- D. vsx_stat

NEW QUESTION # 82
What is the purpose of the VS0 context in a VSX system?
- A. Providing web filtering
- B. Managing shared operating system components
- C. Routing traffic between VSs
- D. Hosting user authentication services
Answer: B
Explanation:
VS0 is the default context used by the VSX Gateway to manage shared resources like the kernel and operating system configurations. It does not perform firewall filtering itself.
NEW QUESTION # 83
What is the use of the command fw monitor in a VS context?
- A. Filters logs per policy layer
- B. Dumps entire firewall rulebase
- C. Captures packet flow at kernel inspection points
- D. Captures real-time CPU usage

NEW QUESTION # 86
In a VSX cluster, how is failover determined for each Virtual System?
- A. Independently per VS using VSLS
- B. By gateway CPU usage
- C. Entire cluster fails over as a unit
- D. By physical interface status
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 # 87
Which command can be used to verify OSPF routes in a Virtual System?
- A. ip route show ospf
- B. show ospf status
- C. netstat -rn
- D. vsx_util show routes

Explanation:
Within a specific VS context, the ip route show ospf command displays OSPF-learned routes.
This is helpful for verifying correct route propagation and troubleshooting dynamic routing issues in the virtualized environment.
NEW QUESTION # 88
Which component in a VSX environment handles dynamic routing on behalf of multiple VSs?
- A. Virtual Switch
- B. Virtual Router
- C. Central Dynamic Routing Daemon
- D. Cluster XL
Answer: C
Explanation:
The Central Dynamic Routing Daemon runs in the VS0 context and manages dynamic routing (OSPF/BGP) for all VSs that are enabled to use it. This centralization simplifies route control and optimizes resource usage across the gateway.
NEW QUESTION # 89
What is the role of the VSX Gateway?
- A. Virtualized platform hosting virtual systems
- B. Management database repository
- C. Host for physical firewall interfaces
- D. Central management server for all firewalls
