Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Built-in high availability with a standby replica
The General Purpose service tier provides built-in high availability through automatic failover to a remote database copy on a different compute node, ensuring availability during planned patching events. Option A is incorrect because active geo-replication is a disaster recovery feature that requires manual configuration. Option B is incorrect because zone-redundant availability is an optional configuration for the General Purpose tier, not provided by default. Option D is incorrect because Business Critical is a separate service tier and not a high availability feature of General Purpose.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Active geo-replication
Why it's wrong here
Active geo-replication is a disaster recovery feature that requires manual configuration, not a default high availability feature.
- ✗
Zone-redundant availability
Why it's wrong here
Zone-redundant availability is an optional configuration for the General Purpose tier, not provided by default.
- ✓
Built-in high availability with a standby replica
Why this is correct
The General Purpose service tier provides built-in high availability through automatic compute failover to a different node. While often described as a standby replica, the mechanism is actually compute failover with shared storage, ensuring availability during planned patching events.
- ✗
Business Critical service tier
Why it's wrong here
Business Critical is a separate service tier with higher availability features, not a high availability feature of General Purpose.
