DBS-C01 Management and Operations Practice Question
Which THREE factors should be considered when planning a cross-Region disaster recovery strategy for an Amazon Aurora MySQL DB cluster? (Choose 3.)
⚠ Common exam trap
Test-takers frequently confuse local failover mechanisms (reader instance priority) with cross-Region disaster recovery, or mistakenly think that provisioned IOPS or storage costs in the target Region are primary considerations when RPO and replication lag are the critical factors.
Answer choices
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
✓
Network latency between source and target Regions.
Network latency between source and target Regions directly impacts the replication lag for Amazon Aurora Global Database. Aurora uses asynchronous replication across Regions, and higher latency increases the delay between committing a transaction on the primary cluster and it being available on the secondary cluster, which affects the achievable Recovery Point Objective (RPO).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Provisioned IOPS for the primary cluster.
Why it's wrong here
IOPS is a performance factor, not DR-specific.
- ✓
Network latency between source and target Regions.
Why this is correct
Latency affects replication lag and RTO.
- ✓
Storage costs in the target Region.
Why this is correct
Storage costs vary and impact DR budget.
- ✗
Failover priority of reader instances.
Why it's wrong here
Failover priority is for within-region Aurora replicas.
- ✓
Recovery Point Objective (RPO) requirements.
Why this is correct
RPO defines acceptable data loss, influencing replication strategy.
