2V0-71.23 Question 60
Select 3You have deployed a Tanzu Kubernetes Grid (TKG) management cluster in your environment. As part of common administration requirements, which actions should you take to ensure proper lifecycle management and operational readiness of the TKG clusters?
- A
Regularly perform backups of the management and workload clusters.
- B
Manually update Kubernetes versions on workload clusters without using Tanzu CLI.
- C
Monitor cluster health and resource utilization using tools like Prometheus and Grafana.
- D
Ensure proper Role-Based Access Control (RBAC) configurations are implemented for cluster users.
- E
Disable automatic reconciliation for cluster resources to avoid configuration drift.
Show answer and explanation
Correct answers: A, C, D
Explanation
Proper administration of Tanzu Kubernetes Grid requires adhering to best practices, including performing regular backups, implementing monitoring solutions, and configuring appropriate RBAC policies. These actions help maintain the clusters' reliability, security, and operational readiness. Manual updates and disabling reconciliation are not recommended, as they introduce unnecessary risks and go against the principles of Kubernetes lifecycle management.
- A. Correct.
Regular backups are critical for ensuring that the management and workload clusters can be restored in case of failure or data corruption. This is a best practice for any Kubernetes-based environment.
- B. Incorrect.
Manually updating Kubernetes versions is not recommended as it can lead to inconsistencies and errors. The Tanzu CLI provides a structured and validated way to upgrade clusters, ensuring compatibility and stability.
- C. Correct.
Monitoring tools like Prometheus and Grafana help administrators track the health and performance of clusters, which is essential for operational readiness and troubleshooting.
- D. Correct.
RBAC ensures that users and applications have appropriate permissions, enhancing security and compliance. Proper RBAC configurations are a fundamental requirement for managing Kubernetes clusters.
- E. Incorrect.
Disabling automatic reconciliation goes against the declarative nature of Kubernetes and Tanzu Kubernetes Grid. Reconciliation ensures that cluster resources remain in their desired state and prevents configuration drift.
