Q12 PostgreSQL Domain 2 · 25–30% of exam Priority · Real Exam

Which statement about Flexible Server high availability with zone redundancy is correct?

  1. A The standby serves read traffic
  2. B The standby is a hot standby that is not readable and takes over on failure (correct answer)
  3. C HA removes the need for backups
  4. 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.
