Scale Out and or Scale Up -> https://d1.awsstatic.com/training-and-certification/docs-sysops-associate/AWS-Certified-SysOps-Administrator-Associate_Sample-Questions_C02.pdf Question 2

what 'eviction' is : Evictions occur when the cache is full and a new item needs to be added, resulting in the removal of an existing item from the cache.

Why Not the Other Options? B. Increase the ElastiCache time to live (TTL): Increasing the TTL would actually keep data in the cache longer, potentially leading to more evictions since old data would stay in memory for longer periods, reducing available space for new data. D. Put an Elastic Load Balancer in front of the ElastiCache cluster: Elastic Load Balancers (ELBs) are used for distributing network traffic across EC2 instances, not for reducing cache evictions. They don't affect memory usage or cache management in ElastiCache. E. Use Amazon SQS to decouple the ElastiCache cluster: Amazon SQS is a message queue service and is unrelated to memory management or caching. It would not reduce evictions in ElastiCache

AC scale up and scale out as the eviction is caused as the resources are not enough

The Evictions metric for Amazon ElastiCache for Memcached represents the number of non- expired items that the cache evicted to provide space for new items. If you are experiencing evictions with your cluster, it is usually a sign that you need to scale up (use a node that has a larger memory footprint) or scale out (add additional nodes to the cluster) to accommodate the additional data.
