156-315.81.20 ClusterXL and VRRP High Availability Practice Question
A security administrator is configuring a ClusterXL High Availability cluster. The administrator wants to verify that the cluster is using the correct synchronization interface and that the synchronization status is healthy. Which command should be used to display the synchronization status of the cluster members?
⚠ Common exam trap
Candidates often confuse general HA status commands like `cpstat ha` with the dedicated synchronization statistics command `cphaprob syncstat`.
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 syncstat` command is designed to show synchronization statistics, including the sync interface and any errors. It allows administrators to confirm that the synchronization network is functioning and that the standby member is receiving updates. Other commands provide interface or general HA status but lack the specific sync details needed for this verification.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
fw ctl pstat
Why it's wrong here
The `fw ctl pstat` command displays various kernel statistics, such as memory usage and packet counts. It does not specifically report on ClusterXL synchronization status or the sync interface. Administrators use it for performance and resource monitoring, not for verifying cluster synchronization.
- ✗
cphaprob -a if
Why it's wrong here
The `cphaprob -a if` command shows the status of monitored interfaces, indicating whether they are up or down. While useful for checking interface health, it does not provide synchronization statistics or confirm that kernel tables are being replicated. It is not the command for verifying sync status.
- ✓
cphaprob syncstat
Why this is correct
The `cphaprob syncstat` command displays detailed synchronization statistics, including the sync interface, the number of updates sent and received, and any errors. It is the correct tool to verify that the synchronization interface is operational and that the members are exchanging state updates without issues.
- ✗
cpstat ha
Why it's wrong here
The `cpstat ha` command provides High Availability status information, such as the current cluster state and member status. However, it does not show detailed synchronization statistics like the number of sync updates or errors. For in-depth sync verification, `cphaprob syncstat` is the appropriate command.
