Q25 Key Vault Domain 4 · 20–25% of exam Priority · Real Exam

An application caches a secret in memory. What is the risk after a rotation?

  1. A Memory leak
  2. B The cached value becomes stale and authentication fails until the cache refreshes (correct answer)
  3. C The vault is locked
  4. D Nothing

Shortcut: Caching is necessary for latency and throttling reasons, but the cache must expire or respond to rotation events, otherwise the app keeps presenting a revoked credential.
