Question 1

You are leading a DevOps project for your organization. The DevOps team is responsible for managing the service infrastructure and being on-call for incidents. The Software Development team is responsible for writing, submitting, and reviewing code. Neither team has any published SLOs. You want to design a new joint-ownership model for a service between the DevOps team and the Software Development team. Which responsibilities should be assigned to each team in the new joint-ownership model?

Options :

A : DevOps team responsibilities Manage the service infrastructure Be on-call for incidents Perform code reviews Software Development team responsibilities Submit code to be reviewed by the DevOps team Publish the SLOs that the DevOps team must meet

B : DevOps team responsibilities Manage the service infrastructure Perform code reviews Software Development team responsibilities Submit code to be reviewed by the DevOps team Be on-call for incidents Publish the SLOs that the DevOps team must meet

C : DevOps team responsibilities Shared responsibilities for code reviews Software Development team responsibilities Manage the service infrastructure Be on-call for incidents on a rotation basis Adopt and publish SLOs for the service Submit code to be reviewed

D : DevOps team responsibilities Manage the service infrastructure Be on-call for incidents Software Development team responsibilities Adopt and publish SLOs for the service Submit code to be reviewed Shared responsibilities for code reviews

Answer: D

Question 2

The application is currently being operated on Compute Engine and the logs are being gathered using Stackdriver. Upon investigation, it has been discovered that certain fields in the log entries contain personally identifiable information (PII). In order to prevent this information from being recorded in new log entries, the affected fields must be restricted as soon as possible.What steps do you need to take?

Options :

A : Use the filter-record-transformer Fluentd filter plugin to remove log entry fields.

B : Use the fluent-plugin-record-reformer Fluentd output plugin to eliminate log entry fields.

C : Wait for developers to fix the application and confirm that PII is no longer visible in log entries.

D : Send log entries to Cloud Storage, then activate a Cloud Function to erase fields and store entries in Stackdriver using the Stackdriver Logging API.

Answer: A

Question 3

What is the advantage of adding a duration parameter to the alert criteria?

Options :

A : Increased error rates

B : Reduced alert frequency

C : Improved precision

D : Increased accuracy

Answer: D

Question 4

You support a Node.js application running on Google Kubernetes Engine (GKE) in production. The application makes several HTTP requests to dependent applications. You want to anticipate which dependent applications might cause performance issues. What should you do?

Options :

A : Instrument all applications with Stackdriver Profiler.

B : Instrument all applications with Stackdriver Trace and review inter-service HTTP requests.

C : Use Stackdriver Debugger to review the execution of logic within each application to instrument all applications.

D : Modify the Node.js application to log HTTP request and response times to dependent applications. Use Stackdriver Logging to find dependent applications that are performing poorly.

Answer: B

Question 5

Service Level Objectives (SLOs) must be established for a multi-region web application that receives high traffic. The customers anticipate the application to maintain high availability and provide prompt response times. At present, the customers are satisfied with the application's performance and availability. The current measurements show that the 90th percentile of latency is 120ms, and the 95th percentile of latency is 275ms over a 28-day period.What would be your recommended latency SLO for the team to meet before publishing?

Options :

A : 90 percentile '"" 100ms th 95 percentile '"" 250ms th

B : 90 percentile '"" 120ms th 95 percentile '"" 275ms th

C : 90 percentile '"" 150ms th 95 percentile '"" 300ms th

D : 90 percentile '"" 250ms th 95 percentile '"" 400ms th
