Topic 1 Question 30
2 つ選択You support a multi-region web service running on Google Kubernetes Engine (GKE) behind a Global HTTP/S Cloud Load Balancer (CLB). For legacy reasons, user requests first go through a third-party Content Delivery Network (CDN), which then routes traffic to the CLB. You have already implemented an availability Service Level Indicator (SLI) at the CLB level. However, you want to increase coverage in case of a potential load balancer misconfiguration, CDN failure, or other global networking catastrophe. Where should you measure this new SLI?
Your application servers' logs.
Instrumentation coded directly in the client.
Metrics exported from the application servers.
GKE health checks for your application servers.
A synthetic client that periodically sends simulated user requests.

👍 19celia202004102021/07/17BE is correct
👍 11Charun2021/06/28as there is an SLI already configured at LB level and they want to increase the coverage then I we need SLI which will detect CDN/LB failures as well. running health checks at application/server level wont cover this. so according to me option B & E are correct which are outside of the GCP infra, which give more coverage and resembles the use behavior
