VCP-VCF Administrator 2024 Question 246
Select 3An administrator needs to place a vSAN host into maintenance mode for hardware replacement. They want to ensure minimal data impact and that the cluster remains operational. Which steps should the administrator follow when setting the vSAN host into maintenance mode?
- A
Ensure there is sufficient free capacity in the vSAN cluster to accommodate data evacuation.
- B
Select the 'Ensure Accessibility' data evacuation option during maintenance mode initiation.
- C
Select 'No Data Migration' option to prevent any data movement during maintenance.
- D
Verify that the vSAN cluster is in a healthy state before placing the host into maintenance mode.
- E
Manually disable Storage DRS on the vSAN cluster before initiating maintenance mode.
Show answer and explanation
Correct answers: A, B, D
Explanation
When placing a vSAN host into maintenance mode, it is essential to ensure there is sufficient capacity for data evacuation, choose the appropriate evacuation option (such as 'Ensure Accessibility'), and verify that the cluster is healthy. These steps help maintain data availability and cluster functionality during maintenance. Avoid unnecessary steps like disabling Storage DRS, as vSAN handles these settings automatically.
- A. Correct.
Ensuring sufficient free capacity in the vSAN cluster is a critical step when placing a host in maintenance mode to avoid potential data movement failures.
- B. Correct.
The 'Ensure Accessibility' option is a common choice to maintain cluster availability while minimizing data evacuation time. It ensures that all data remains accessible during the maintenance period.
- C. Incorrect.
'No Data Migration' is not recommended in this scenario as it does not ensure data redundancy and might lead to data unavailability if there are further failures.
- D. Correct.
It is important to verify the vSAN cluster's health before initiating maintenance mode to avoid issues during or after the maintenance process.
- E. Incorrect.
Disabling Storage DRS manually is not required for vSAN clusters, as vSAN manages data placement independently.
