CV0-004 Cloud Architecture and Design Practice Question
A company is deploying a web application that requires high availability across two geographically separate data centers. The application must be active in both sites simultaneously, and traffic must be load-balanced between them. Which architecture best meets these requirements?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Active-active architecture
Active-active architecture allows both sites to handle traffic simultaneously, providing load balancing and high availability. Active-passive would leave one site idle. Warm standby implies one site is not fully active. Fault tolerance (N+1) is a component-level concept, not a site-level architecture.
