Which action should the SysOps administrator take to accomplish this goal?

  • A. Deploy the ElastiCache cluster with Memcached as the engine.
  • B. Deploy the Redis cluster within an Auto Scaling group to launch replicas across multiple Availability Zones.
  • C. Verify that cluster mode is disabled. Increase the number of shards.

Selected Answer: D
Multi-AZ (Availability Zone) with automatic failover is a feature in Amazon ElastiCache for Redis that provides enhanced fault tolerance. When Multi-AZ is enabled, ElastiCache automatically creates replicas of the primary node in different Availability Zones. In case the primary node becomes unavailable due to a hardware failure, network issue, or other reasons, ElastiCache will automatically promote one of the replicas to be the new primary, ensuring minimal downtime.

Answer D: Check FAQ in this link Q: Can I have replicas in the same Availability Zone as the primary? Yes. Note that placing both the primary and the replica(s) in the same Availability Zone will not make your Amazon ElastiCache for Redis replication group resilient to an Availability Zone disruption. Additionally this well not be allowed if Multi-AZ is turned on. https://aws.amazon.com/elasticache/faqs/#Redis https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/AutoFailover.html
