Step-by-Step Solution
Solution:
Step 1: Understand combining routing policies
Latency-based routing directs users to the fastest region; failover routing provides backup if that region fails.Step 2: Apply combined strategy
Use latency-based routing for primary endpoints in multiple regions and failover routing to backup endpoints in each region. correctly uses latency routing for primaries and failover routing for backups per region.Final Answer:
Use latency-based routing for primary endpoints in multiple regions and failover routing to backup endpoints in each region. -> Option AQuick Check:
Latency + failover = fast and reliable routing [OK]
Quick Trick: Combine latency routing for speed and failover for backup [OK]
Common Mistakes:
- Disabling latency routing unnecessarily
- Using weighted routing instead of latency
- Skipping health checks in failover
