Which scenario would cause automatic HA synchronization to fail due to software versions, per the provided guidance?

• A. Different build versions
• B. Identical build versions
• C. Same time zone
• D. No network connectivity

Answer: (A)

Automatic HA synchronization requires both nodes to run the same software version. When the two nodes are on different build versions, their binaries, state representations, and the replication protocol may not be compatible. This mismatch means the synchronization process cannot correctly interpret or apply the exchanged state, leading to a failure to synchronize. If the builds are identical, the protocol, data formats, and feature expectations align, so synchronization can proceed smoothly. A different time zone doesn’t affect software compatibility, and while no network connectivity would block synchronization, that’s a connectivity issue rather than a version issue.
