NEW QUESTION # 53
An administrator is adding a new ESXi host to an existing vSphere cluster. When selecting the cluster, the administrator Is unable to use the Cluster Quickstart workflow to add and configure the additional host.
What could be the root cause of this issue?
- A. The administrator has previously dismissed the Cluster Quickstart workflow.
- B. The administrator must manually add the host to the cluster before using the Cluster Quickstart workflow.
- C. The administrator has not been assigned the required permissions to use the Cluster Quickstart workflow.
- D. The administrator must enable the Cluster Quickstart workflow option in VMware vCenter.
Answer: A
Explanation:
Option A is correct because it indicates that the administrator has previously dismissed the Cluster Quickstart workflow, which will prevent them from using it to add and configure an additional host. To use the Cluster Quickstart workflow again, the administrator must enable it in the cluster settings. Option B is incorrect because the administrator does not need to manually add the host to the cluster before using the Cluster Quickstart workflow, as this is one of the steps in the workflow. Option C is incorrect because the administrator does not need any special permissions to use the Cluster Quickstart workflow, as long as they have permissions to perform cluster operations. Option D is incorrect because there is no option to enable the Cluster Quickstart workflow in VMware vCenter, as this is a feature of vSphere clusters. Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vcenterhost.doc/GUID-9F9E3F8C-0E2B-4B6A-8C5C-3F8E5F6B4E9D.html
