You provide support for a multi-region web service operating on Google Kubernetes Engine (GKE), which is managed by a Global HTTP/S Cloud Load Balancer (CLB). Due to legacy reasons, user requests are initially processed by a third-party Content Delivery Network (CDN) before being directed to the CLB. While an availability Service Level Indicator (SLI) is already in place at the CLB level, you seek to enhance monitoring to address potential risks such as load balancer misconfigurations, CDN failures, or other global networking issues. Where should you implement this new SLI? (Select two options.)
