Topic 1 Question 593
A solutions architect is designing a highly available Amazon ElastiCache for Redis based solution. The solutions architect needs to ensure that failures do not result in performance degradation or loss of data locally and within an AWS Region. The solution needs to provide high availability at the node level and at the Region level.
Which solution will meet these requirements?
Use Multi-AZ Redis replication groups with shards that contain multiple nodes.
Use Redis shards that contain multiple nodes with Redis append only files (AOF) turned on.
Use a Multi-AZ Redis cluster with more than one read replica in the replication group.
Use Redis shards that contain multiple nodes with Auto Scaling turned on.

Hate to say this, but I read the two docs linked below, and I still think the answer is A. Turning on AOF helps in data persistence after failure, but it does nothing for availability unless you use Multi-AZ replica groups.

Multi-AZ replication groups provide automatic failover between AZs if there is an issue with the primary AZ. This provides high availability at the region level
