Google Professional Cloud DevOps Engineer Exam - Topic 12 Question 9 Discussion

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?Choose 2 answers
C) Metrics exported from the application servers and D) GKE health checks for your application servers
A) Your application servers' logs
B) Instrumentation coded directly in the client
E) A synthetic client that periodically sends simulated user requests

A synthetic client? That sounds a bit overkill, right?

C could be useful, but not as proactive as E.

I feel like metrics from application servers could be useful, but I’m not sure if they would cover CDN failures effectively.

GKE health checks seem relevant, but I wonder if they would capture issues that happen before reaching the load balancer.

I remember we discussed measuring SLIs at different points in the architecture, but I'm not sure if application logs would give us the coverage we need.

I think using a synthetic client could be a good option since it simulates user requests, but I’m not entirely confident about how often it should run.

I like the idea of using a combination of workflow rules and formula fields in option D. That could be an efficient way to populate key fields without too much manual effort. I'll make sure to understand how those features work.

Hmm, this question seems to be asking about the advantages of load balancing. I'll need to think carefully about the key benefits it provides.
