Answer: D

Explanation:

According to the VMware vRealize Operations Install and Configure Guide1, when upgrading the vRealize Operations cluster via the Administration UI, the cluster status should change from offline to online after the upgrade process is completed. However, if the cluster status remains offline or fails during the upgrade, the administrator can use the Finish Installation option to resume the upgrade process. The Finish Installation option attempts to bring the cluster online and complete the upgrade. The administrator can monitor the progress of the upgrade from the Administration UI or the Cluster Management page.

The other options are not suitable for managing this problem and continuing the installation process. The Rollback Installation option is used to revert the cluster to the previous version of vRealize Operations, not to resume the upgrade process. The Rollback Installation option is only available if the cluster is online and the upgrade has failed. The administrator should not manually take the cluster offline, as this would interrupt the upgrade process and cause data loss or corruption.
