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
✓
Implement an active-active architecture across on-premises and cloud
Using multiple availability zones within a region protects against data center failure. An active-active architecture ensures both on-premises and cloud are handling traffic, providing redundancy. Deploying in a single zone creates a single point of failure. Using only on-premises does not leverage cloud for HA. A single load balancer is a SPOF.
