Vault Enterprise Fault Tolerant Vault Environments Practice Question
You are troubleshooting a sync issue in Performance Replication. The logs indicate 'replication lag'. Which parameter should you review to ensure optimal data synchronization between clusters?
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
✓
The network connection and replication buffer throughput.
While there isn't a single 'lag' parameter, review the 'replication_buffer_size' or network throughput limits between clusters as part of diagnosing synchronization bottlenecks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The network connection and replication buffer throughput.
Why this is correct
Replication lag is usually due to network congestion or inadequate buffer capacity.
- ✗
The 'disable_mlock' setting.
Why it's wrong here
This controls memory locking and is unrelated to network replication.
- ✗
The 'max_lease_ttl' value.
Why it's wrong here
This affects token expiration, not replication lag.
- ✗
The 'default_max_request_size'.
Why it's wrong here
This limits request sizes, not replication performance.
