Which statement about Flexible Server high availability with zone redundancy is correct?
- A The standby serves read traffic
- B The standby is a hot standby that is not readable and takes over on failure (correct answer)
- C HA removes the need for backups
- D HA requires a read replica
Shortcut: The zone-redundant standby is kept in sync and promoted automatically on failure, but it does not accept client connections. Read scale-out requires read replicas.
