You support an application running on App Engine. The application is used globally and accessed from various device types. You want to know the number of connections. You are using Stackdriver Monitoring for App Engine. What metric should you use?

• A.flex/connections/current
• B.tcp_ssl_proxy/new_connections
• C.tcp_ssl_proxy/open_connections
• D.flex/instance/connections/current

You are configuring connectivity across Google Kubernetes Engine (GKE) clusters in different VPCs You notice that the nodes in Cluster A are unable to access the nodes in Cluster B You suspect that the workload access issue is due to the network configuration You need to troubleshoot the issue but do not have execute access to workloads and nodes You want to identify the layer at which the network connectivity is broken What should you do?

• A.Use Network Connectivity Center to perform a Connectivity Test from Cluster A to Cluster
• B.Use a debug container to run the traceroute command from Cluster A to Cluster B and from Cluster B to Cluster A Identify the common failure point
• C.Install a toolbox container on the node in Cluster A Confirm that the routes to Cluster B are configured appropriately
• D.Enable VPC Flow Logs in both VPCs and monitor packet drops

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

• A.Metrics exported from the application servers
• B.GKE health checks for your application servers
• C.Instrumentation coded directly in the client
• D.A synthetic client that periodically sends simulated user requests
• E.Your application servers' logs

You support an application deployed on Compute Engine. The application connects to a Cloud SQL instance to store and retrieve dat a. After an update to the application, users report errors showing database timeout messages. The number of concurrent active users remained stable. You need to find the most probable cause of the database timeout. What should you do?

• A.Use Cloud Security Scanner to see whether your Cloud SQL is under a Distributed Denial of Service (DDoS) attack.
• B.Check the serial port logs of the Compute Engine instance.
• C.Determine whether there is an increased number of connections to the Cloud SQL instance.
• D.Use Stackdriver Profiler to visualize the resources utilization throughout the application.
