Master
1/5
Your web application uses Amazon ElastiCache to store session state information. However, you notice uneven cache hit ratios across your cache cluster, leading to suboptimal latency in some scenarios. Which caching strategy should you implement to improve cache hit ratios and maintain consistent latency?
a.
Increase the TTL for all cache entries uniformly to improve cache hits.
b.
Deploy an additional cache cluster in a separate region for redundancy.
c.
Store all session data in a single cache node to ensure higher availability.
d.
Implement consistent hashing to distribute keys evenly across the cluster.
