      Practice

      (1/5)
      1. What does creating a VM instance in Google Cloud allow you to do?
      easy
      A. Create a database
      B. Store files permanently
      C. Run a virtual computer in the cloud
      D. Send emails automatically

      Solution

      1. Step 1: Understand VM instance purpose

        A VM instance is a virtual machine, like a computer inside the cloud.

      2. Step 2: Identify correct function

        Running a virtual computer matches the VM instance role, unlike storing files or sending emails.

      3. Final Answer:

        Run a virtual computer in the cloud -> Option C

      4. Quick Check:

        VM instance = virtual computer [OK]
      Hint: VM means virtual machine, a computer in the cloud [OK]
      Common Mistakes:
      • Confusing VM with storage service
      • Thinking VM creates databases directly
      • Assuming VM sends emails automatically
      2. Which command correctly creates a VM instance named my-vm in zone us-central1-a with machine type e2-medium and image debian-11?
      easy
      A. gcloud create vm my-vm --zone us-central1-a --type e2-medium --image debian-11
      B. gcloud compute vm create my-vm --zone=us-central1-a --machine-type=e2-medium --image debian-11
      C. gcloud instances create --name my-vm --zone us-central1-a --machine e2-medium --image debian-11
      D. gcloud compute instances create my-vm --zone=us-central1-a --machine-type=e2-medium --image-family=debian-11 --image-project=debian-cloud

      Solution

      1. Step 1: Check correct command structure

        The correct command starts with 'gcloud compute instances create' followed by the instance name.

      2. Step 2: Verify flags and parameters

        Flags like '--zone', '--machine-type', '--image-family', and '--image-project' must be exact and use '=' sign.

      3. Final Answer:

        gcloud compute instances create my-vm --zone=us-central1-a --machine-type=e2-medium --image-family=debian-11 --image-project=debian-cloud -> Option D

      4. Quick Check:

        Correct gcloud syntax = gcloud compute instances create my-vm --zone=us-central1-a --machine-type=e2-medium --image-family=debian-11 --image-project=debian-cloud [OK]
      Hint: Use 'gcloud compute instances create' with exact flags [OK]
      Common Mistakes:
      • Using wrong command verbs like 'create vm'
      • Missing '=' in flags
      • Wrong flag names like '--machine' instead of '--machine-type'
      3. What will happen if you run this command?
      gcloud compute instances create test-vm --zone=us-east1-b --machine-type=n1-standard-1 --image-family=ubuntu-2004-lts --image-project=ubuntu-os-cloud
      medium
      A. The command will fail due to missing machine type
      B. A VM named test-vm will be created in zone us-east1-b with Ubuntu 20.04 OS
      C. A VM will be created but with default image, not Ubuntu
      D. The VM will be created in the wrong zone

      Solution

      1. Step 1: Analyze command parameters

        The command specifies instance name, zone, machine type, image family, and image project correctly.

      2. Step 2: Understand image selection

        Using '--image-family=ubuntu-2004-lts' with '--image-project=ubuntu-os-cloud' selects Ubuntu 20.04 LTS image.

      3. Final Answer:

        A VM named test-vm will be created in zone us-east1-b with Ubuntu 20.04 OS -> Option B

      4. Quick Check:

        Correct flags create VM with specified OS [OK]
      Hint: Image family + project picks correct OS image [OK]
      Common Mistakes:
      • Confusing image-family with image name
      • Omitting image-project causes errors
      • Wrong zone spelling
      4. You tried to create a VM with:
      gcloud compute instances create vm1 --zone=us-west1-c --machine-type=e2-small --image=debian-10

      The command failed with an error about the image. What is the likely cause?
      medium
      A. The image name 'debian-10' is incorrect or deprecated
      B. The zone 'us-west1-c' does not exist
      C. The machine type 'e2-small' is invalid
      D. You forgot to specify the project

      Solution

      1. Step 1: Check image parameter validity

        Using '--image=debian-10' is often invalid because images require full name or image family with project.

      2. Step 2: Understand error cause

        Image errors usually mean the image name is wrong or deprecated, not zone or machine type.

      3. Final Answer:

        The image name 'debian-10' is incorrect or deprecated -> Option A

      4. Quick Check:

        Image errors = wrong image name [OK]
      Hint: Use image family and project, not just image name [OK]
      Common Mistakes:
      • Assuming zone or machine type caused image error
      • Not specifying image project with image family
      • Using outdated image names
      5. You want to create a VM instance that automatically allows HTTP traffic and uses a custom startup script to install software. Which command correctly achieves this?
      hard
      A. gcloud compute instances create web-vm --zone=us-central1-a --machine-type=e2-medium --image-family=debian-11 --image-project=debian-cloud --tags=http-server --metadata=startup-script='sudo apt-get update && sudo apt-get install -y nginx'
      B. gcloud compute instances create web-vm --zone=us-central1-a --machine-type=e2-medium --image=debian-11 --allow-http --script='install nginx'
      C. gcloud compute instances create web-vm --zone=us-central1-a --machine-type=e2-medium --image-family=debian-11 --image-project=debian-cloud --firewall=http --startup='apt-get install nginx'
      D. gcloud compute instances create web-vm --zone=us-central1-a --machine-type=e2-medium --image=debian-11 --http --metadata=startup='install nginx'

      Solution

      1. Step 1: Enable HTTP traffic with tags

        Using '--tags=http-server' allows HTTP traffic via firewall rules.

      2. Step 2: Add startup script correctly

        '--metadata=startup-script=' followed by the script installs nginx on startup.

      3. Step 3: Verify image and machine type

        Using '--image-family=debian-11' and '--image-project=debian-cloud' is correct for Debian 11.

      4. Final Answer:

        gcloud compute instances create web-vm --zone=us-central1-a --machine-type=e2-medium --image-family=debian-11 --image-project=debian-cloud --tags=http-server --metadata=startup-script='sudo apt-get update && sudo apt-get install -y nginx' -> Option A

      5. Quick Check:

        Tags + metadata=startup-script = correct setup [OK]
      Hint: Use --tags for HTTP and --metadata for startup script [OK]
      Common Mistakes:
      • Using wrong flags like --allow-http or --http
      • Incorrect metadata key name
      • Not specifying image project with image family
