An administrator is attempting to use Update Manager to patch a cluster of ESXi 5.x hosts.
The administrator needs to stage the patches for a scheduled update after hours. When verifying the hosts after the scheduled upgrade, the administrator determines that one of the hosts was not remediated and patches are not staged. The host is using PXE as its boot method.
What condition would cause this behavior?
A. The host was rebooted prior to the scheduled remediation.
B. Remediating PXE-booted hosts using Update Manager is unsupported.
C. The user account used does NOT have the Remediate Hosts privilege.
D. The RAMdisk on the host has insufficient capacity.
Correct Answer: A
Explanation/Reference:
Explanation:
Update Manager 5.5 lets you to remediate PXE booted ESXi 5.x hosts. Update Manager does not apply patches that require a reboot to PXE booted ESXi hosts.
If there is any additional software installed on the PXE booted ESXi host, the software might be lost if the host restarts. You should update your image profile with the additional software so that it will be present after the reboot.
You can configure Update Manager to let other software initiate remediation of PXE booted ESXi 5.x hosts. The remediation installs patches and software modules on the hosts, but typically the host updates are lost after a reboot.
The global setting in the Update Manager Configuration tab enables solutions such as ESX Agent Manager or Cisco Nexus 1000V to initiate remediation of PXE booted ESXi 5.x hosts. In contrast, the Enable patch remediation of powered on PXE booted ESXi hosts setting in the Remediate wizard enables
Update Manager to patch PXE booted hosts.
To retain updates on stateless hosts after a reboot, use a PXE boot image that contains the updates. You can update the PXE boot image before applying the updates with Update Manager, so that the updates are not lost because of a reboot. Update Manager itself does not reboot the hosts because it does not install updates requiring a reboot on PXE booted ESXi 5.x hosts.
Incorrect Answers:
B: Remediating PXE-booted hosts using Update Manager is supported. Therefore, this answer is incorrect.
C: It’s unlikely that the problem was caused by a permissions issue; the remediation was successful on the other hosts in the cluster. Therefore, this answer is incorrect.
D: When you upgrade an ESXi host with less than 10MB of free space in its /tmp directory, although Update Manager indicates that the remediation process completed successfully, the ESXi host is not upgraded. Therefore, if the disk had insufficient space, a successful remediation would be reported so this answer is incorrect.
