AWS - Route 53

You want to configure Route 53 to route traffic to two servers: one in US-East and one in US-West. You want 80% of traffic to go to US-East and 20% to US-West, but only if the servers are healthy. Which routing policy and configuration should you use?

AWeighted routing with health checks enabled on both records

BSimple routing with health checks enabled on both records

CLatency routing with weights 80 and 20 assigned

DGeolocation routing with health checks disabled

Step-by-Step Solution

Solution:

Step 1: Identify routing policy for traffic split with health checks
Weighted routing allows traffic split by percentages and supports health checks to route only to healthy servers.
Step 2: Exclude other options
Simple routing does not split traffic, latency routing does not use weights, and geolocation routing is based on user location, not weights.
Final Answer:
Weighted routing with health checks enabled on both records -> Option A
Quick Check:
Weighted routing + health checks = weighted traffic to healthy servers [OK]

Quick Trick: Use weighted routing with health checks for weighted, healthy routing [OK]

Common Mistakes:

Using simple routing for traffic splitting
Assigning weights in latency routing
Disabling health checks when needed
