2V0-71.23 Question 178
Select 3You are tasked with implementing a backup and restore strategy for a Tanzu Kubernetes cluster running multiple critical workloads. The organization requires backup solutions that ensure consistent snapshots of the cluster and its associated persistent volumes. Which of the following steps are necessary to successfully back up and restore the cluster?
- A
Use Velero to back up the Kubernetes cluster's resources and persistent volume data.
- B
Manually copy etcd data from the control plane node to a secure location.
- C
Ensure that the CSI (Container Storage Interface) drivers support snapshot functionality for persistent volumes.
- D
Restart all workloads after restoring the cluster to ensure application consistency.
- E
Schedule regular backups to an offsite storage location for disaster recovery purposes.
Show answer and explanation
Correct answers: A, C, E
Explanation
To effectively back up and restore a Tanzu Kubernetes cluster, you need to leverage tools like Velero for resource and persistent volume backups. It is essential to verify CSI driver snapshot support to ensure compatibility with persistent volume snapshots. Additionally, regular offsite backups are crucial for disaster recovery. Manual etcd backups and restarting workloads are not recommended or required steps in this process.
- A. Correct.
Correct. Velero is widely used for backing up Kubernetes resources and persistent volume data. It provides consistent snapshots and integrates with Tanzu Kubernetes clusters.
- B. Incorrect.
Incorrect. While etcd contains cluster state information, manually copying etcd data is not a standard or recommended method for backup in Tanzu Kubernetes clusters.
- C. Correct.
Correct. Persistent volume snapshot functionality depends on the underlying CSI drivers. Ensuring CSI driver support is critical for successful volume backups.
- D. Incorrect.
Incorrect. While restarting workloads might occasionally be necessary, it is not a required step for a successful backup and restore process.
- E. Correct.
Correct. Regularly scheduling backups to an offsite location is a best practice for disaster recovery to ensure backups are safe from on-premises failures.
