[All AWS Certified SysOps Administrator - Associate Questions]

An ecommerce company uses an Amazon ElastiCache for Memcached cluster for in-memory caching of popular product queries on the shopping site. When viewing recent Amazon CloudWatch metrics data for the ElastiCache cluster, the SysOps administrator notices a large number of evictions.
Which of the following actions will reduce these evictions? (Choose two.)

  • A. Add an additional node to the ElastiCache cluster.
  • B. Increase the ElastiCache time to live (TTL).
  • C. Increase the individual node size inside the ElastiCache cluster.
  • D. Put an Elastic Load Balancer in front of the ElastiCache cluster.
  • E. Use Amazon Simple Queue Service (Amazon SQS) to decouple the ElastiCache cluster.

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

premium version? :) the premium version says (and my brief humble research got matched with this): "A. Add an additional node to the ElastiCache cluster. Adding more nodes to the cluster increases the overall memory available for caching, reducing the likelihood of evictions. Each additional node adds more memory capacity, allowing more data to be stored in the cache without evicting existing items. C. Increase the individual node size inside the ElastiCache cluster. By increasing the size of each node, you increase the amount of memory available in each node. This additional memory can accommodate more cached data, decreasing the need to evict older data when new data needs to be cached."

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

Selected Answer: AC
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.
