An application team wishes to use Amazon ElastiCache to improve their application performance. The application frequently requests the same items. The team wants to minimize cache space utilization and infrastructure costs. Which caching strategy should the team employ?

Answer options:

A.Write-Through
B.Lazy Loading
C.Write-Around
D.Write-Back

Answer: B
Option A is incorrect because, with the Write-Through caching strategy, the data in the cache is updated every time it`s written to the database. This means data that is not frequently read is also stored in the cache, thus using up cache space.
Option B is CORRECT because Lazy Loading caching strategy loads data into the cache only when the application requests it. Thus, it reduces the use of cache space by items not frequently requested.
Option C is incorrect because the Write-Around caching pattern is a form of the Write-Through caching strategy.
Option D is incorrect because Write-Back caching pattern is a form of the Write-Through caching strategy.
