The correct answer is D. Update the break_replication_timeout to 15 seconds. The NCC check warns when the Metro Availability break_replication_timeout is set below the recommended minimum of 15 seconds. Updating the timeout to 15 seconds satisfies the NCC requirement and ensures Metro protection domain stability.
Question
An administrator has configured Metro Availability but a few hours later got an NCC warning:
Node x.x.X.X:
WARN: Break replication timeout of Metro protection domain 'M1' is below the recommended minimum. What is a possible resolution for this issue?
Options
- AUpdate the break_replication_timeout to 10 seconds.
- BUpdate the break_replication_timeout to 5 milliseconds.
- CUpdate the break_replication_timeout to 15 milliseconds.
- DUpdate the break_replication_timeout to 15 seconds

Why each option
The NCC check warns when the Metro Availability break_replication_timeout is set below the recommended minimum of 15 seconds. Updating the timeout to 15 seconds satisfies the NCC requirement and ensures Metro protection domain stability.
10 seconds is still below the recommended minimum of 15 seconds and would not resolve the NCC warning.
5 milliseconds is far below the minimum threshold and would make the configuration critically non-compliant, not resolve the warning.
15 milliseconds is also far below the minimum 15-second threshold and would not satisfy the NCC check requirement.
The Nutanix NCC health check for Metro Availability enforces a recommended minimum break_replication_timeout of 15 seconds to allow sufficient time for the system to detect and handle replication interruptions before breaking the stretch cluster. Setting the value to 15 seconds resolves the WARN state and aligns the configuration with Nutanix best practices for Metro protection domains.
