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.(lex/jnstance/connections/current
• B.tcp_ssl_proxy/new_connections
• C.tcp_ssl_proxy/open_connections
• D.flex/connections/current

You support an application that stores product information in cached memory. For every cache miss, an entry is logged in Stackdriver Logging. You want to visualize how often a cache miss happens over time. What should you do?

• A.Link Stackdriver Logging as a source in Google Data Studio. Filler (he logs on the cache misses.
• B.Create a logs-based metric in Stackdriver Logging and a dashboard for that metric in Stackdriver Monitoring.
• C.Configure BigOuery as a sink for Stackdriver Logging. Create a scheduled query to filter the cache miss logs and write them to a separate table
• D.Configure Stackdriver Profiler to identify and visualize when the cache misses occur based on the logs.

You are part of an organization that follows SRE practices and principles. You are taking over the management of a new service from the Development Team, and you conduct a Production Readiness Review (PRR). After the PRR analysis phase, you determine that the service cannot currently meet its Service Level Objectives (SLOs). You want to ensure that the service can meet its SLOs in production. What should you do next?

• A.Identify recommended reliability improvements to the service to be completed before handover.
• B.Adjust the SLO targets to be achievable by the service so you can bring it into production.
• C.Bring the service into production with no SLOs and build them when you have collected operational data.
• D.Notify the development team that they will have to provide production support for the service.

You are managing an application that exposes an HTTP endpoint without using a load balancer. The latency of the HTTP responses is important for the user experience. You want to understand what HTTP latencies all of your users are experiencing. You use Stackdriver Monitoring. What should you do?

• A.* In your application, create a metric with a metricKind set to DELTA and a valueType set to DOUBLE.
  * In Stackdriver's Metrics Explorer, use a Slacked Bar graph to visualize the metric.
• B.* In your application, create a metric with a metricKind set to CUMULATIVE and a valueType set to DOUBLE.
  * In Stackdriver's Metrics Explorer, use a Line graph to visualize the metric.
• C.* In your application, create a metric with a metricKind set to gauge and a valueType set to distribution.
  * In Stackdriver's Metrics Explorer, use a Heatmap graph to visualize the metric.
• D.* In your application, create a metric with a metricKind. set toMETRlc_KIND_UNSPECIFIEDanda valueType set to INT64.
  * In Stackdriver's Metrics Explorer, use a Stacked Area graph to visualize the metric.
