Exam 2V0-21.23 topic 1 question 88 discussion

DE A - no NTP support in VMware Tools B - no official support in doc C - no support for ESXi only Workstation D - describle in doc E - VMXNET 3 is not supported by OS drivers

https://docs.vmware.com/en/VMware-Tools/12.2.0/com.vmware.vsphere.vmwaretools.doc/GUID-6994A5F9-B62B-4BF1-99D8-E325874A4C7A.html

Honestly I don't see how Vmware tools could deal with unsupoorted network drivers. And it is common to have a host shared drive in guest. So for me is C and D.

From the official guide: VMware Tools enhances the performance of a VM and makes many of the ease-of-use features in VMware products possible: • Faster graphical performance • Shared folders between host and guest file systems • Copying and pasting text, graphics, and files between the virtual machine and the host or client desktop • Scripting that helps automate guest operating system operations Although the guest operating system can run without VMware Tools, many VMware features are not available until you install VMware Tools. For example, if VMware Tools is not installed in your VM, you cannot use the shutdown or restart options from the toolbar. You can use only the power options.

CD (Support for unsupported network device drivers) is not a valid use case for VMware Tools. VMware Tools provides drivers for supported devices to enhance performance and compatibility but does not support unsupported drivers.

C & D: From the official VMware book: VMware Tools enhances the performance of a VM and makes many of the ease-of-use features in VMware products possible: • Faster graphical performance • Shared folders between host and guest file systems • Copying and pasting text, graphics, and files between the virtual machine and the host or client desktop • Scripting that helps automate guest operating system operations Benefits and features include: • Device drivers — SVGA display — VMXNET/VMXNET3 — Balloon driver for memory management — Sync driver for quiescing I/O — Paravirtual SCSI controller • Increased graphical performance •Improved mouse performance • Guest OS heartbeat service • Time synchronization • Ability to shut down the VM remotely

CD is correct

Selected Answer: DE Reference: https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-esxi-host-client/GUID-28C39A00-743B-4222-B697-6632E94A8E72.html

De is correct D because vnic drivers are required.

I'm going B&D Why B is valid: "Salt requires a salt-minion to be deployed in the guest. Salt specific guest variables are set on the host side per VM basis and subsequently read by VMware Tools inside guest. VMware Tools then downloads the salt bundle and spins up a salt-minion instance inside the guest." https://docs.vmware.com/en/VMware-Tools/12.2.0/com.vmware.vsphere.vmwaretools.doc/GUID-373CD922-AF80-4B76-B19B-17F83B8B0972.html

if guest OS runs on workstation, C is right. now this subject is focus on vsphere, i don't think C is suitable

VMware Tools allows you to open file share paths between hosts and VMs as an experimental feature. However, this is not recommended for vSphere environments due to security concerns, so it's hard to see this as a use case. So I'm going to go with a very vague statement: unsupported network driver support.

Ill go with D&E

Tricky, but as per the lecture manual: A - no, NTP not used B - no, quite clearly C - Yes, shared folder access D - Yes, ability to remotely shut down E - no. While VMXNET3 driver provided, there are many other unsupported drivers which VM tools is not going to include either.

AD the official blue print only mentions Time sync and remote shutdown Yes you can share folders but thats using vmware workstation; this exam doesn't include this.

VMTools only syncs with host , no external NTP source. VMTools also enables Shared Folders between host and guest file systems ( on VMware Workstation and VMware Fusion ). https://docs.vmware.com/en/VMware-Workstation-Pro/17/com.vmware.ws.using.doc/GUID-D6D9A5FD-7F5F-4C95-AFAB-EDE9335F5562.html

C&D - checked in the student book as RainWhisper said
