AWS Certified Developer Associate DVA-C02 Practice Question

Your application frequently reads user profile data that can experience sudden spikes in traffic, while profile updates occur only occasionally. To reduce database load and latency you plan to add a cache. You also want to minimize operating costs and ensure profiles are not served stale for long periods. Which caching approach best satisfies these requirements?

  • Implement write-through caching to keep the cache synchronized with every database update

  • Employ a lazy-loading caching strategy with an appropriate time-to-live (TTL) to maintain freshness

  • Avoid caching and continue to serve all reads directly from the database

  • Use a read-through caching layer so the cache automatically fetches data on a miss
