You support a high-traffic web application that runs on Google Cloud Platform (GCP). You need to measure application reliability from a user perspective without making any engineering changes to it.
What should you do?
Choose 2 answers

  1. Review current application metrics and add new ones as needed.
  2. Modify the code to capture additional information for user interaction.
  3. Analyze the web proxy logs only and capture response time of each request.
  4. Create new synthetic clients to simulate a user journey using the application.
  5. Use current and historic Request Logs to trace customer interaction with the application.

Answer(s): D,E

Explanation:

The most effective ways to measure application reliability from a user perspective without making any engineering changes are to create new synthetic clients to simulate a user journey using the application, and to use current and historic Request Logs to trace customer interaction with the application. These methods can help you monitor the availability, latency, and errors of your application from an end-user perspective .



You support an application deployed on Compute Engine. The application connects to a Cloud SQL instance to store and retrieve dat

  1. 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?
  2. Check the serial port logs of the Compute Engine instance.
  3. Use Stackdriver Profiler to visualize the resources utilization throughout the application.
  4. Determine whether there is an increased number of connections to the Cloud SQL instance.
  5. Use Cloud Security Scanner to see whether your Cloud SQL is under a Distributed Denial of Service (DDoS) attack.

Answer(s): C

Explanation:

The most probable cause of the database timeout is an increased number of connections to the Cloud SQL instance. This could happen if the application does not close connections properly or if it creates too many connections at once. You can check the number of connections to the Cloud SQL instance using Cloud Monitoring or Cloud SQL Admin API .



Your organization recently adopted a container-based workflow for application development. Your team develops numerous applications that are deployed continuously through an automated build pipeline to a Kubernetes cluster in the production environment. The security auditor is concerned that developers or operators could circumvent automated testing and push code changes to production without approval.
What should you do to enforce approvals?

  1. Configure the build system with protected branches that require pull request approval.
  2. Use an Admission Controller to verify that incoming requests originate from approved sources.
  3. Leverage Kubernetes Role-Based Access Control (RBAC) to restrict access to only approved users.
  4. Enable binary authorization inside the Kubernetes cluster and configure the build pipeline as an attestor.

Answer(s): D

Explanation:

The keywords here is "developers or operators". Option A the operators could push images to production without approval (operators could touch the cluster directly and the cluster cannot do any action against them). Rest same as francisco_guerra.



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?

  1. flex/connections/current
  2. tcp_ssl_proxy/new_connections
  3. tcp_ssl_proxy/open_connections
  4. flex/instance/connections/current

Answer(s): A
