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

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

Correct Answer: B

Some of your production services are running in Google Kubernetes Engine (GKE) in the eu-west-1 region. Your build system runs in the us-west-1 region. You want to push the container images from your build system to a scalable registry to maximize the bandwidth for transferring the images to the cluster. What should you do?

1. A. Push the images to Google Container Registry (GCR) using the gcr.io hostname.
2. B. Push the images to Google Container Registry (GCR) using the us.gcr.io hostname.
3. C. Push the images to Google Container Registry (GCR) using the eu.gcr.io hostname.
4. D. Push the images to a private image registry running on a Compute Engine instance in the eu-west-1 region.

Correct Answer: C
Hostname Storage location gcr.io Stores images in data centers in the United States asia.gcr.io Stores images in data centers in Asia eu.gcr.io Stores images in data centers within member states of the European Union us.gcr.io Stores images in data centers in the United States

Your team is designing a new application for deployment both inside and outside Google Cloud Platform (GCP). You need to collect detailed metrics such as system resource utilization. You want to use centralized GCP services while minimizing the amount of work required to set up this collection system. What should you do?

1. A. Import the Stackdriver Profiler package, and configure it to relay function timing data to Stackdriver for further analysis.
2. B. Import the Stackdriver Debugger package, and configure the application to emit debug messages with timing information.
3. C. Instrument the code using a timing library, and publish the metrics via a health check endpoint that is scraped by Stackdriver.
4. D. Install an Application Performance Monitoring (APM) tool in both locations, and configure an export to a central data storage location for analysis.

Correct Answer: A

You are running a real-time gaming application on Compute Engine that has a production and testing environment. Each environment has their own Virtual Private Cloud (VPC) network. The application frontend and backend servers are located on different subnets in the environment's VPC. You suspect there is a malicious process communicating intermittently in your production frontend servers. You want to ensure that network traffic is captured for analysis. What should you do?

1. A. Enable VPC Flow Logs on the production VPC network frontend and backend subnets only with a sample volume scale of 0.5.
2. B. Enable VPC Flow Logs on the production VPC network frontend and backend subnets only with a sample volume scale of 1.0.
3. C. Enable VPC Flow Logs on the testing and production VPC network frontend and backend subnets with a volume scale of 0.5. Apply changes intesting before production.
4. D. Enable VPC Flow Logs on the testing and production VPC network frontend and backend subnets with a volume scale of 1.0. Apply changes in testing before production.

Correct Answer: D

You support a service that recently had an outage. The outage was caused by a new release that exhausted the service memory resources. You rolled back the release successfully to mitigate the impact on users. You are now in charge of the post-mortem for the outage. You want to follow Site Reliability Engineering practices when developing the post-mortem. What should you do?

1. A. Focus on developing new features rather than avoiding the outages from recurring.
2. B. Focus on identifying the contributing causes of the incident rather than the individual responsible for the cause.
3. C. Plan individual meetings with all the engineers involve
4. D. Determine who approved and pushed the new release to production.
5. E. Use the Git history to find the related code commi
6. F. Prevent the engineer who made that commit from working on production services.

Correct Answer: B
