Set timeouts on your application so that you can fail requests faster.

B.

Send custom metrics for each of your requests to Stackdriver Monitoring.

C.

Use Stackdriver Monitoring to look for insights that show when your API latencies are high.

D.

Instrument your application with Stackdnver Trace in order to break down the request latencies at each
microservice.

You are creating a solution to remove backup files older than 90 days from your backup Cloud Storage bucket. You want to optimize ongoing Cloud Storage spend. What should you do?

B.

Create a shutdown script registered as a xinetd service in Linux and configure a Stackdnver endpoint
check to call the service.

C.

Create a shutdown script and use it as the value for a new metadata entry with the key shutdown-script
in the Cloud Platform Console when you create the new virtual machine instance.

D.

Create a shutdown script, registered as a xinetd service in Linux, and use the gcloud compute instances
add-metadata command to specify the service URL as the value for a new metadata entry with the key
shutdown-script-url

A recent audit that a new network was created in Your GCP project. In this network, a GCE instance has an SSH port open the world. You want to discover this network's origin. What should you do?
