Exam SOA-C03 Topic 3 Question 91 Discussion

Actual exam question for Amazon's SOA-C03 exam
Question #: 91
Topic #: 3
A company uses Amazon ElastiCache (Redis OSS) to cache application data. A CloudOps engineer must implement a solution to increase the resilience of the cache. The solution also must minimize the recovery time objective (RTO).
Which solution will meet these requirements?

Suggested Answer: C Vote an answer

Enabling Multi-AZ with automatic failover for ElastiCache for Redis provides high availability and the lowest possible RTO, as Redis automatically promotes a replica to primary if the primary node fails. This ensures near-instant recovery without manual intervention, unlike backup-based solutions, which involve downtime and manual restores.
