Question 35
The production application is currently deployed on virtual machine instances under the management of a managed instance group in Compute Engine. The instances receive traffic through an HTTP(s) load balancer. However, users are currently unable to access the application. The goal is to implement a monitoring method that will notify when the application is not available.
What method would be the best option for you to select?
- A Stackdriver uptime checks
- B Smoke tests
- C Cloud Load Balancing - heath checks
- D Managed instance group - heath checks
Reveal correct answer
Correct answer: A
Explanation
The correct technique to implement monitoring of an application deployed on Compute Engine virtual machine instances controlled by a managed instance group and accessed via a HTTP(s) load balancer is Stackdriver uptime checks. According to the Professional Google Cloud Developer documentation, Stackdriver uptime checks can help verify that your application is available and accessible to users by sending periodic requests to a specified URL and checking for expected responses. Uptime checks can be configured to monitor the load balancer's IP address or the instances themselves, and can be set up with alerting policies to notify you when the application is unavailable. This makes Stackdriver uptime checks the ideal choice for monitoring the availability of an application deployed on Compute Engine virtual machines and accessed via a HTTP(s) load balancer.Discussion
