- Question 1Intermediate
Object Storage · Multicloud Gateway
You are configuring the Multicloud Object Gateway (MCG) to store data in a hybrid environment. You need to ensure that specific data buckets are stored on an on-premises Ceph cluster, while others are stored in AWS S3. What MCG resource should you configure to define these specific storage targets?
Show answer & explanation
Correct answer: A
A
BackingStorein NooBaa (MCG) represents a connection to a specific storage target, such as an AWS S3 bucket or a local Ceph RGW. You create distinct BackingStores for each target and then map buckets to them. - Question 2Advanced
Troubleshooting · Component Failure
During a routine check, you notice that an OSD (Object Storage Daemon) pod is in a
CrashLoopBackOffstate. After inspecting the logs, you suspect a physical drive failure. Which OpenShift CLI command sequence is appropriate to identify the failed device associated with the OSD?Show answer & explanation
Correct answer: A
To identify the failed OSD, you first locate the OSD pods. Then, accessing the Ceph tools pod (or executing via the operator) allows you to run
ceph osd treeto see which OSD ID isdown. You can then map this ID to the physical device UUID in the OSD pod description or PV. - Question 3AdvancedSelect 2
Security · Encryption
An organization requires strict encryption for all data at rest within their OpenShift Data Foundation cluster. They want to manage the encryption keys using an external HashiCorp Vault. Which two actions are required to configure this? (Select TWO)
Show answer & explanation
Correct answers: B, D
The
StorageClusterCustom Resource must be configured withencryption: trueand thekmssection pointing to the connection details for the external Vault.ODF requires a Kubernetes Secret with specific keys (like address, token, etc.) to authenticate and communicate with the external KMS.
- Question 4Beginner
Backup and Restore · OADP
True or False: When using the OpenShift API for Data Protection (OADP) to back up applications backed by Ceph CSI volumes, you must have a Snapshot Controller installed and a VolumeSnapshotClass configured.
Show answer & explanation
Correct answer: A
True. OADP relies on the CSI snapshotting capabilities to take consistent backups of Persistent Volumes. This requires the Kubernetes Snapshot Controller and a valid VolumeSnapshotClass to mediate between the API and the Ceph storage backend.
- Question 5Intermediate
Object Storage · Bucket Policies
A storage administrator wants to configure a BucketClass in the Multicloud Object Gateway to improve data resilience. The goal is to ensure that every object uploaded is immediately copied to two different cloud providers (AWS S3 and Azure Blob). Which policy type should be selected in the BucketClass definition?
Show answer & explanation
Correct answer: C
The 'Mirror' placement policy creates full copies of the data across the defined BackingStores. This ensures that if one provider is unavailable, the data is accessible from the other.
- Question 6Intermediate
Operations · Scaling
You are expanding an internal mode OpenShift Data Foundation cluster. You have added three new worker nodes to the OpenShift cluster, each with appropriate raw disks. You want ODF to use these new nodes to expand capacity. What is the correct sequence of actions?
Show answer & explanation
Correct answer: D
ODF uses labels to identify which nodes are part of the storage cluster. Labeling the new nodes ensures the operator targets them. Depending on the deployment strategy (auto-discovery vs manual), you may then need to update the StorageCluster to reflect the intention to scale.
