A vSphere administrator needs to use vSphere Update Manager to perform orchestrated upgrades of virtual machines.
Which two options are available for virtual machine remediation? (Choose two.)
A. Upgrade virtual machine hardware
B. Upgrade VMware tools
C. Upgrade virtual machine appliances
D. Upgrade virtual machine guest OS
Correct Answer: AB
Explanation/Reference:
Explanation:
You can use an orchestrated upgrade to upgrade the virtual machine hardware and VMware Tools of all the virtual machines in the vSphere inventory at the same time, using baseline groups containing the following baselines:
VM Hardware Upgrade to Match Host
VMware Tools Upgrade to Match Host
Upgrading the virtual hardware of the virtual machines exposes new devices and capabilities to the guest operating systems. You must upgrade VMware Tools before upgrading the virtual hardware version so that all required drivers are updated in the guest. You cannot upgrade the virtual hardware of the virtual machines if VMware Tools is not installed, is out of date, or is managed by third-party tools.
You can manually remediate virtual machines and virtual appliances immediately, or can schedule a remediation at a time that is convenient for you.
You can perform an orchestrated upgrade by using a virtual machine baseline group. The VMware Tools upgrade baseline runs first, followed by the virtual machine hardware upgrade baseline.
Incorrect Answers:
C: You cannot upgrade virtual machine appliances with virtual machine remediation. Therefore, this answer is incorrect.
D: You cannot upgrade virtual machine guest operating systems with virtual machine remediation. Therefore, this answer is incorrect.
