💡 Hint

Common Mistakes

Using a template name that does not exist

Omitting the --template flag

The --template flag requires the exact name of the instance template to use for the managed instance group.

medium

Complete the code to update the size of the managed instance group to 5.

GCP

gcloud compute instance-groups managed resize my-group --size=[1] --zone=us-central1-a

Common Mistakes

Setting size to a smaller number accidentally

Using a non-numeric value

The --size flag sets the desired number of instances in the managed instance group.

3fill in blank

hard

Fix the error in the command to set the autohealing policy for the managed instance group.

GCP

gcloud compute instance-groups managed set-autohealing-policies my-group --health-check=[1] --initial-delay=300 --zone=us-central1-a

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

💡 Hint

Common Mistakes

Using a health check name that does not exist

Misspelling the health check name

The --health-check flag requires the exact name of the health check resource.

4fill in blank

hard

Fill both blanks to create a managed instance group with autoscaling enabled and set the max number of instances.

GCP

gcloud compute instance-groups managed create my-group --template=[1] --size=2 --zone=us-central1-a && gcloud compute instance-groups managed set-autoscaling my-group --max-num-replicas=[2] --zone=us-central1-a

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

💡 Hint

Common Mistakes

Using an invalid template name

Setting max replicas too low or too high

The first blank is the instance template name. The second blank is the maximum number of replicas for autoscaling.

5fill in blank

hard

Fill all three blanks to update the instance template, resize the group, and set the autoscaling minimum size.

GCP

gcloud compute instance-groups managed rolling-action start-update my-group --version=template=[1] --zone=us-central1-a && gcloud compute instance-groups managed resize my-group --size=[2] --zone=us-central1-a && gcloud compute instance-groups managed set-autoscaling my-group --min-num-replicas=[3] --zone=us-central1-a

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

💡 Hint

Common Mistakes

Mixing up template names

Setting size or min replicas incorrectly

The first blank is the new instance template name for the update. The second blank is the new size of the group. The third blank is the minimum number of replicas for autoscaling.
