Why Compute Engine provides VM flexibility in GCP - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the machine type for a VM instance.

GCP

machine_type = "zones/us-central1-a/machineTypes/[1]"

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using incomplete or incorrect machine type names.

Omitting the 'n1-' prefix.

The correct machine type format includes the prefix 'n1-standard-1' to specify the VM size.

medium

Complete the code to create a custom VM with specific CPU and memory.

GCP

custom_machine = f"custom-[1]"  # CPUs and memory in MB

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using commas or other separators instead of dashes.

Confusing memory units.

Custom machine types use a dash '-' to separate CPU count and memory size in MB.

3fill in blank

hard

Fix the error in the code to set the number of CPUs for a custom VM.

GCP

custom_cpu = int([1])  # Number of CPUs as integer

Drag options to blanks, or click blank then click option'

A'four'

B4.0

C4

D"4"

💡 Hint

Common Mistakes

Passing float values to int() causing errors.

Using non-numeric strings.

The number of CPUs must be converted from a string to an integer using int("4").

4fill in blank

hard

Fill both blanks to create a VM instance with a custom machine type and zone.

GCP

instance_config = {
  "machineType": "zones/[1]/machineTypes/custom-4-8192",
  "zone": "[2]"
}

Drag options to blanks, or click blank then click option'

Aus-central1-a

Beurope-west1-b

Casia-east1-c

Dus-west1-b

Attempts:

💡 Hint

Common Mistakes

Using different zones in machineType and zone fields.

Using invalid zone names.

The machine type and zone must match; here both use 'us-central1-a' for consistency.

5fill in blank

hard

Fill all three blanks to define a VM instance with custom CPU, memory, and zone.

GCP

vm_instance = {
  "machineType": "zones/[1]/machineTypes/custom-[2]-[3]",
  "name": "custom-vm-1"
}

Drag options to blanks, or click blank then click option'

Aus-east1-b

B6

C12288

Dus-west1-a

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing zone names or using invalid zones.

Using non-numeric CPU or memory values.

The zone is 'us-east1-b', CPU count is 6, and memory is 12288 MB for this custom VM.
