VCP-VCF Administrator 2024 Question 245
Select 4An administrator needs to place a vSAN host into maintenance mode for hardware maintenance. The cluster is configured with vSAN and has workloads actively running. Which considerations and steps must the administrator follow to ensure data availability and minimal disruption during this process?
- A
Choose the 'Ensure Accessibility' option to ensure data is accessible during maintenance.
- B
Select the 'Evacuate All Data' option to migrate all data off the host before entering maintenance mode.
- C
Ensure the cluster has adequate free capacity to accommodate the data evacuation if 'Evacuate All Data' is selected.
- D
Directly power off the host without placing it into maintenance mode to save time.
- E
Use the 'No Data Migration' option if minimal disruption is required and data redundancy is sufficient.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
When placing a vSAN host into maintenance mode, the administrator must select the appropriate data evacuation option based on the maintenance purpose and duration. 'Ensure Accessibility' is suitable for short-term maintenance, while 'Evacuate All Data' is recommended for longer or indefinite maintenance to ensure data safety. The 'No Data Migration' option is only appropriate if redundancy is sufficient and disruption is acceptable. Powering off the host without maintenance mode risks data loss or availability issues.
- A. Correct.
Correct: The 'Ensure Accessibility' option ensures that active workloads remain accessible by maintaining a single copy of data on other hosts in the cluster. This is useful for scenarios requiring minimal time in maintenance mode.
- B. Correct.
Correct: The 'Evacuate All Data' option migrates all data from the host to other hosts, ensuring no data is lost in case of prolonged maintenance or host removal.
- C. Correct.
Correct: Adequate free capacity in the cluster is necessary when evacuating data to avoid capacity or performance issues during the migration.
- D. Incorrect.
Incorrect: Powering off the host without entering maintenance mode can lead to data unavailability or integrity issues, as vSAN assumes the host is still active.
- E. Correct.
Correct: The 'No Data Migration' option can be used if the administrator is confident in the cluster's redundancy and the maintenance period is short.
