GCP - Cloud Load Balancing
You want to implement a global HTTP(S) Load Balancer that routes traffic to regional backend services based on user location for latency optimization. Which feature should you use?
ACloud CDN with geo-based cache keys
BCloud Load Balancing with geo-based routing using backend service regionality
CCloud Armor security policies
DBackend service affinity with session cookies
Step-by-Step Solution
Solution:
  1. Step 1: Identify feature for geo-based routing

    Google Cloud HTTP(S) Load Balancer supports routing to backend services in different regions to optimize latency based on user location.
  2. Step 2: Evaluate options

    Cloud CDN caches content but does not route by location, Cloud Armor is for security, session affinity manages sessions but not geo-routing.
  3. Final Answer:

    Cloud Load Balancing with geo-based routing using backend service regionality -> Option B
  4. Quick Check:

    Geo-routing uses backend regionality in load balancer [OK]
Quick Trick: Use backend regionality for geo-routing in load balancer [OK]
Common Mistakes:
  • Confusing CDN caching with geo-routing
  • Using security policies for routing
  • Relying on session affinity for location-based routing
