The Elasticache cluster contains 10 shards, as can be seen from the list below. The two nodes in each cluster are all members of the same REplicationGroup. Multi-AZ is disabled and Auto-failover is enabled.

Here, only us-east-1a and us-east-1a are used. us-east-1c and us-east-1d are not used. How to evenly distribute the nodes to the four AZs? (with the cli or console)
Does Multi-AZ needs to be enabled?
