💡 Hint

Common Mistakes

Using Pod or Service instead of PersistentVolumeClaim in kind.

The kind field specifies the type of Kubernetes object. For a PersistentVolumeClaim, it must be PersistentVolumeClaim.

Complete the code to specify the storage size requested in the PVC spec.

Kubernetes

spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: [1]

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

💡 Hint

Common Mistakes

Omitting units or using invalid units for storage size.

The storage field defines the amount of storage requested. 5Gi means 5 gibibytes.

Fix the error in the accessModes list to allow only one access mode: ReadWriteOnce.

Kubernetes

spec:
  accessModes:
    - [1]

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

AReadWriteOnce

BReadOnlyMany

CReadWriteMany

DWriteOnce

Attempts:

💡 Hint

Common Mistakes

Using invalid access modes like WriteOnce or ReadOnlyMany when only ReadWriteOnce is allowed.

ReadWriteOnce means the volume can be mounted as read-write by a single node. This is a common access mode for PVCs.

hard

Fill both blanks to specify the storage class name and the storage size in the PVC spec.

Kubernetes

spec:
  storageClassName: [1]
  resources:
    requests:
      storage: [2]

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

💡 Hint

Common Mistakes

Mixing storage class names with storage sizes or using invalid sizes.

The storageClassName defines the type of storage to use, e.g., fast-storage. The storage request defines the size, e.g., 10Gi.

5fill in blank

hard

Fill all three blanks to complete the PVC spec with access mode, storage class, and storage size.

Kubernetes

spec:
  accessModes:
    - [1]
  storageClassName: [2]
  resources:
    requests:
      storage: [3]

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

💡 Hint

Common Mistakes

Using incorrect access modes or mismatching storage class and size.

The PVC spec requires an access mode like ReadWriteOnce, a storage class name like fast-storage, and a storage size like 20Gi.
