An administrator must gracefully restart a virtual machine (VM) through the vSphere Client but the option is greyed out. The administrator has full administrative access on VMware vCenter and all the objects available in vCenter, but has no access to log onto the operating system.
Which action should the administrator take to meet the objective?
If the option to gracefully restart a VM is greyed out in the vSphere Client, it indicates there might be a communication issue between the vCenter and the host, or the VMware Tools are not installed on the VM. Since the administrator has full administrative access on VMware vCenter and all objects but no access to log onto the operating system, the best course of action is to restart the vCenter. This action can help resolve any potential communication problems between the vCenter and the host, which might be causing the greyed-out option.
D. Migrating to another host seems like the sensible option, but this KB suggests Restarting the vCenter might be the answer. https://kb.vmware.com/s/article/82562 I'm guessing that if the issue is communication between the vCenter and the Host, a vMotion could become stuck if you're unlucky. As for installing the tools, you need to have access to the OS to do so.
Answer D. If the restart option is greyed out, that means the VMware Tools are not installed, or there is an issue on vCenter. If the VMware Tools are not installed, the only way to make the initial install is to log onto the guest OS...which is impossible here. We can then suppose the VMware Tools are already installed, but the communication with the vCenter does not work. So we restart the vCenter.
Installing VMware Tools will enable the graceful restart option for the virtual machine, as well as other features such as time synchronization and guest OS customization. It's not necessary to log into the OS in order to install VMware Tools. In vSphere Client – Hosts and Clusters view > right-click the Virtual Machine > Guest OS > Install VMware Tools.
C is not correct, because to install vmtools you need to have access to the OS: if you select install vmtoos from vCenter, there are only two options available: "mount" and "cancel". So, is not automatic process. I agree with mkhlszf, option D (restart vcenter) is the best option based in this KB: https://kb.vmware.com/s/article/82562
Instal Tools is correct
Update to D --> Because no Access to OS
VMware Tools allows detailed guest information to be displayed as well as allowing you to perform operations on the guest OS, e.g. graceful shutdown, reboot, etc. You should install VMware Tools.
correction - cannot install vmware tools without access to the OS, so the last resort will be to restart vcenter option D
Install VM Tools
Update to D --> Because no Access to OS
Must be D since according to this document (https://kb.vmware.com/s/article/1014294), you have to log on to a VM in order to install VMware Tools. The question says there's no access to the OS, and thus the administrator *cannot* install VMware Tools.
https://kb.vmware.com/s/article/82562 KB article stating issue can be caused by communication issue to be fixed by restarting vCenter
It says gracefully restart which would be unavailable if VMware Tools is not installed.
Option A From https://core.vmware.com/resource/vsphere-replication-technical-overview It recommends to upgrade hw version when detected symptoms like: Some virtual machine operations are greyed out and unavailable
restart vcenter https://kb.vmware.com/s/article/2048748
Link is dead :(
Is it expected that the VM has VMware Tools installed? It is a key information that is missing and are needed for gracefully restart/shutdown. This information completely changes the importance of the second one with "no access to log onto the operating system". If there are VMware Tools and the options are greyed out, then it can be vCenter problem, if not you need to install them on the VM. Probably the worst question in this dump.
C. It's not necessary to log into the OS in order to install VMware Tools. In vSphere Client – Hosts and Clusters view > right-click the Virtual Machine > Guest OS > Install VMware Tools. https://kb.vmware.com/s/article/2004754
Anywhere within that KB says you don't need to log into the OS to install vmtools. The way you said will mount the ISO, not install the vmtools.
I change to D. Reading other articles yo need to log into the OS
Installing VMware Tools will enable the graceful restart option for the virtual machine, as well as other features such as time synchronization and guest OS customization.
C is not possible as the there is no access to log into the operating system. automatic upgrade of tolls is possible when tools is installed, but automatic install of tools when its not present is not.
