Question No. 13
A website’s page load times are gradually increasing as more users access the system at the same
time. Analysis indicates that a user profile is being loaded from a database in all the web pages being
visited by each user and this is increasing the database load and the page load latency. To address
this issue the Developer decides to cache the user profile data.
Which caching strategy will address this situation MOST efficiently?

B/D? Both use ElastiCache which is smart for fast access, but cache-aside (B) lets the app fetch from cache first and update only if needed, avoiding unnecessary writes unlike write-through (D).

B. Cache-aside lets the app load from cache first and update only when needed, which is simple and efficient here. ElastiCache fits well for fast access without adding DB overhead.

Not C, using a dedicated RDS for caching just adds overhead since RDS isn’t optimized for caching. ElastiCache with cache-aside (option B) is better for reducing latency and DB hits effectively.

B seems best for reducing DB load with cache-aside strategy.
