Question
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 two.)
Options
- AYour application servers' logs.
- BInstrumentation coded directly in the client.
- CMetrics exported from the application servers.
- DGKE health checks for your application servers.
- EA synthetic client that periodically sends simulated user requests.
