AWS Certified SysOps Administrator – Associate (legacy) — Question 206

You are using ElastiCache Memcached to store session state and cache database queries in your infrastructure. You notice in CloudWatch that Evictions and
GetMisses are Doth very high.
What two actions could you take to rectify this? (Choose two.)

Answer options

• A. Increase the number of nodes in your cluster
• B. Tweak the max_item_size parameter
• C. Shrink the number of nodes in your cluster
• D. Increase the size of the nodes in the duster

Correct answer: A, D

Explanation

Increasing the number of nodes in your cluster (Option A) can help distribute the load, reducing evictions and get misses. Similarly, increasing the size of the nodes in the cluster (Option D) allows for more data to be stored, which also mitigates evictions. Options B and C are not effective as tweaking the max_item_size may not address the root cause of high evictions and reducing nodes would worsen the problem.
