Question 3

You operate a set of Compute Engine VMs running a web application.

Using only Cloud Console, what is the fastest way to verify recent snapshot creation activity for these disks?

Accepted Answer

Open Compute Engine > Snapshots and check the creation timestamps of recent snapshots to see if they match the schedule interval.

Answer

Create a Cloud Monitoring uptime check against the VMs to detect whether the disks are reachable.

Answer

Enable the Cloud Monitoring agent on each VM and build a dashboard that plots disk I/O throughput.

Answer

Request a quota increase for persistent disk snapshots in the affected region.

Question 4

Open the 'orders-api' service in the Cloud Run section of the Console and view the automatically collected logs in the LOGS tab.

Answer

Install the Ops Agent inside the container image, redeploy the service, and view the metrics in Cloud Monitoring.

Answer

Create a Cloud Logging export sink to BigQuery and run SQL queries to find the 500 responses.

Answer

SSH into the underlying Compute Engine instance backing the Cloud Run service and tail the container log file.

Question 6

You have just installed the Google Cloud CLI on your new laptop. Before you can run commands against your company's project, you need to authenticate your user account so gcloud can obtain and store credentials. Which command should you run to sign in with your Google account through a browser-based flow?

Accepted Answer

gcloud auth login

Answer

gcloud auth activate-service-account

Answer

gcloud config set account

Answer

Question 7

You have just installed the Google Cloud CLI on a new workstation and authenticated with your corporate account. Before running deployment commands, you want to quickly confirm which account, project, and default region/zone the CLI will use for subsequent commands. Which command should you run?

Accepted Answer

gcloud config list

Answer

gcloud auth login --verify

Answer

gcloud projects describe

Answer

gcloud info --run-diagnostics

Question 8

You just installed the Google Cloud CLI on a new laptop and authenticated with your corporate account. Every time you run 'gcloud compute instances create', the CLI prompts you to select a zone interactively, which slows down your scripting. You want the CLI to stop prompting and always target europe-west1-b by default, without having to pass a flag on each command. What should you do?

Accepted Answer

Run 'gcloud config set compute/zone europe-west1-b' to store the default zone in the active configuration.

Answer

Set an environment variable 'GCLOUD_ZONE=europe-west1-b' in your shell profile.

Answer

Add '--zone=europe-west1-b' to every command using a shell alias, since gcloud cannot store a default zone.

Answer

Run 'gcloud init' again and choose europe-west1-b, which is the only way to persist a zone.

Question 9

You have just installed the Google Cloud CLI on a new workstation and authenticated with your corporate account. You will be running dozens of gcloud commands against a project named 'analytics-prod-421' over the next few hours, and you do not want to append the --project flag to every command. What is the most efficient way to make all subsequent gcloud commands target this project by default?

Accepted Answer

Run 'gcloud config set project analytics-prod-421' to set the project in the active configuration.

Answer

Set an environment variable 'export GOOGLE_PROJECT=analytics-prod-421' before running each command.

Answer

Run 'gcloud projects update analytics-prod-421 --set-default' to mark the project as the CLI default.

Answer

Edit the ~/.config/gcloud/credentials.db file to add the project ID as the default value.

Question 10
