Google Cloud Professional Cloud Developer — Question 30

You have an application in production. It is deployed on Compute Engine virtual machine instances controlled by a managed instance group. Traffic is routed to the instances via a HTTP(s) load balancer. Your users are unable to access your application. You want to implement a monitoring technique to alert you when the application is unavailable.
Which technique should you choose?

Answer options

• A. Smoke tests
• B. Stackdriver uptime checks
• C. Cloud Load Balancing - heath checks
• D. Managed instance group - heath checks

Correct answer: B

Explanation

The correct answer is B, Stackdriver uptime checks, as it specifically monitors the availability of your application and can alert you when it is down. Option A, smoke tests, are typically used for basic functionality checks but do not directly monitor uptime. Options C and D refer to health checks that assess the health of the load balancer and the instance group, respectively, but they do not provide direct alerts for application availability.
