Disaster recovery and backup strategies are essential for maintaining high availability and reliability in Kubernetes-based environments. This topic focuses on how Kubernetes handles failures, performs data backups, and restores workloads.
Through these carefully crafted multiple-choice questions (MCQs), learners can gain a strong understanding of best practices, built-in tools, and third-party options for disaster recovery in Kubernetes. These MCQs are especially valuable for those preparing for Kubernetes certifications, interviews, and real-world operational scenarios.
1.) What is the main component responsible for storing the Kubernetes cluster state?
2.) Which command is used to take a snapshot of the etcd database?
3.) Which of the following is NOT stored in an etcd snapshot?
4.) Which open-source tool is commonly used for Kubernetes backup and restore?
5.) What must be configured for Velero to store backups in AWS S3?
6.) How do you initiate a backup in Velero?
7.) What type of resource is used to capture volume snapshots in Kubernetes?
8.) Which plugin must be installed to use volume snapshots in Kubernetes?
9.) What does RTO stand for in disaster recovery?
10.) What happens if a backup file is corrupted?
