Question 1

You are designing an architecture for a new web application that uses Azure Database for PostgreSQL - Flexible Server.

The application requires high availability with an SLA of 99.99%. In the event of an infrastructure failure, the database must fail over automatically with zero data loss (RPO = 0) and minimal downtime.

Which high availability configuration should you recommend?

Accepted Answer

Identify the PostgreSQL Flexible Server HA option that uses synchronous replication across physical data centers.

Question 2

What mistakes do candidates make on this AZ-305 question?

Accepted Answer

Confusing Read Replicas with HA. Read replicas are for read scale-out and cross-region DR, but they use asynchronous replication, meaning data loss can occur during a sudden failure.
