156-315.81.20 ClusterXL and VRRP High Availability Practice Question
Which command is used to manually verify the synchronization status of the kernel tables between ClusterXL members?
⚠ Common exam trap
Candidates often select general high-availability status commands like cphaprob stat instead of the specific synchronization-focused command required for kernel tables.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
cphaprob syncstat
The 'cphaprob' command is the primary utility for troubleshooting and verifying ClusterXL status. Specifically, 'cphaprob syncstat' provides detailed information regarding the synchronization of kernel tables. Monitoring this output is critical for identifying synchronization latency, missed updates, or connection table mismatches that could lead to dropped packets or session resets after a failover event, ensuring that both members maintain consistent state information.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
cphaprob stat
Why it's wrong here
The 'cphaprob stat' command shows the general status of the cluster members, including their current role (Active/Standby) and their health state. It does not provide detailed information about the kernel table synchronization progress, error counts, or the specific status of individual table updates between the cluster members.
- ✓
cphaprob syncstat
Why this is correct
The 'cphaprob syncstat' command is specifically designed to show statistics for the kernel table synchronization. It displays information about how many updates were sent, received, and any potential issues with the synchronization process. This is the correct tool for verifying that the members are communicating their state data effectively.
- ✗
fw ctl pstat
Why it's wrong here
The 'fw ctl pstat' command provides information about the firewall kernel performance, memory usage, and general packet processing statistics. It does not display information regarding the synchronization between cluster members. While useful for general troubleshooting, it is not the intended command for inspecting cluster synchronization table status.
- ✗
cphaprob list
Why it's wrong here
The 'cphaprob list' command displays a list of registered critical devices that the cluster monitors to determine the health of the member. It does not show the status of the synchronization of connection tables or the performance of the synchronization link between the members in the high availability cluster.
