Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a resource quota named mem-quota in the dev namespace.

Kubernetes

kubectl create quota mem-quota --hard=[1] --namespace=dev

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

Amemory=1Gi

Bcpu=2

Cpods=5

Dstorage=10Gi

💡 Hint

Common Mistakes

Using CPU or pod limits instead of memory for this quota.

Omitting the namespace flag.

The --hard flag sets the resource limits. Here, memory=1Gi limits memory usage to 1 GiB.

medium

Complete the YAML snippet to define a resource quota limiting pods to 10 in the test namespace.

Kubernetes

apiVersion: v1
kind: ResourceQuota
metadata:
  name: pod-quota
  namespace: test
spec:
  hard:
    pods: [1]

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

💡 Hint

Common Mistakes

Setting the value too low or too high.

Confusing pod count with CPU or memory limits.

The pods field under hard sets the maximum number of pods allowed. Here, it is set to 10.

hard

Fix the error in this command to apply a resource quota YAML file named quota.yaml to the prod namespace.

Kubernetes

kubectl apply -f [1] --namespace=prod

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

💡 Hint

Common Mistakes

Using wrong file extensions like .json or .txt.

Misspelling the file name.

The file name must match exactly. The standard YAML file extension is .yaml.

4fill in blank

hard

Fill both blanks to create a resource quota YAML that limits CPU to 2 cores and memory to 4Gi in the staging namespace.

Kubernetes

apiVersion: v1
kind: ResourceQuota
metadata:
  name: cpu-mem-quota
  namespace: staging
spec:
  hard:
    cpu: [1]
    memory: [2]

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

💡 Hint

Common Mistakes

Using units for CPU like '2Gi'.

Setting memory without units.

The CPU limit is set as a number (2 cores), and memory uses units like Gi. So CPU is 2 and memory is 4Gi.

5fill in blank

hard

Fill all three blanks to create a resource quota YAML that limits pods to 3, CPU to 1, and memory to 2Gi in the qa namespace.

Kubernetes

apiVersion: v1
kind: ResourceQuota
metadata:
  name: qa-quota
  namespace: qa
spec:
  hard:
    pods: [1]
    cpu: [2]
    memory: [3]

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

💡 Hint

Common Mistakes

Mixing up the order of values.

Forgetting units for memory.

The pods limit is 3, CPU is 1 core, and memory is 2Gi as per the question.
