An administrator is running a variety of vSphere 6.5 cluster configurations and is tasked with upgrading to vSphere 7.0.
Which two conditions could cause potential conflicts or outages to the virtual machines (VMs)? (Choose two.)
An administrator is running a variety of vSphere 6.5 cluster configurations and is tasked with upgrading to vSphere 7.0.
Which two conditions could cause potential conflicts or outages to the virtual machines (VMs)? (Choose two.)
When upgrading to vSphere 7.0, two potential conditions that could cause conflicts or outages to virtual machines include datastores attached to the hosts based on VMFS3 and the upgrade of a vSphere Distributed Switch with VMs attached. ESXi 7.0 no longer supports VMFS3 datastores and automatically upgrades them to VMFS5, which can create disruption if not handled properly. Additionally, upgrading a distributed switch can cause brief network interruptions, impacting the VMs connected to it.
A) No. No impact on VMs B) No. "ESXi and vCenter Server supports VMFS3, VMFS5, and VMFS6 datastores. You can continue to use existing VMFS3 datastores, but you cannot create new VMFS3 datastores." [https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vcenter.upgrade.doc/GUID-49E8A38B-A356-4665-8F95-38163FB3A220.html] C) Yes. "The upgrade of a distributed switch causes the hosts and virtual machines attached to the switch to experience a brief downtime. For more information, see KB 52621.". Although it says "You must upgrade to DVS version 6.0 or later before you upgrade to vCenter Server 7.0", and vCenter 7 supports DVS 6.5.0+, so that really depends on the version currently in use D) No. No impact on VMs. E) Outdated/incompatible VIBs could make the host instable and therefore potentially cause VMs outage
Mware vSphere 6.5 (ESXi 6.5) allows use of VMFS3 in a read/write mode however VMware vSphere 7.0 (ESXi 7.0) no longer supports VMFS3 datastores. This could potentially cause downtime for virtual machines.
Option E - can cause ESXi upgrade to fail, but has no impact on virtual machines. A host can have custom virtual installation bundles (VIBs) installed, for example, third-party drivers or management agents. When you upgrade an ESXi host to 7.0, all supported custom VIBs are migrated, regardless of whether the VIBs are included in the installer ISO. If the host or the installer ISO image contains a VIB that creates a conflict and prevents the upgrade, an error message identifies the VIB that created the conflict. So in this specific context this is not the right option.
You are correct that 7.0 does not support VMFS3 anymore and upgrades it automatically to VMFS5. But as far as I know this happens online even with running VMs. http://www.vmwarearena.com/upgrade-datastore-from-vmfs3-to-vmfs5/ Seems to be a tricky one here...I think I will go with C & E, becaus if some the possibility of instabilies after a successfull upgrade that may happen later.
In response to phukat, the question says "conflict" or "impact" so its not only impact to VMs we are looking for but conflicting config as well. You are correct VMFS is not supported in vSphere 7, but it will automatically upgrade those datastores non disruptively, so that is neither impact nor conflict. Custom VIBs however may cause a failure as you say, which is also a conflict, which is what the question asks for. So CE are the correct options.
B & C. B - ESXi can't use the VMFS3 datastores so the VM might need to be shutdown to migrate. C - Network interruption during the distributed switch upgrade. All other options are only impating Virtual Centre which has no direct impact on the VMs.
VMFS3 volumes ESXi and vCenter Server supports VMFS3, VMFS5, and VMFS6 datastores. You can continue to use existing VMFS3 datastores, but you cannot create new VMFS3 datastores. If you have VMFS3 datastores, upgrade them to VMFS6. For more information on VMFS datastores, see the vSphere Storage documentation.
It's C & E, distributed switches & third party vibs. Passed 500/500 today.
CE Correct Passed 500/500 Today 1-Dec-22
Cannot be B as VMFS3 is upgradable to VMFS5, however VMFS5 is supported but NOT upgradable and New VMFS6 news be created and VMS migrated to it
C and E.
Only viable options
cannot be B (Datastores attached to the hosts based on VMFS3) because once Esxi upgraded to 7 and rebooted it will detect VMFS3 and upgrades it to VMFS5, and esxi 7 can work with VMFS5 but canot upgrade it to VMFS6, in that case you will need to create new VMFS datastore and migrate the vms off VMFS5 (which is not need here), SO in Short NO way B. As NOTE i by Mistake give your answer thumbs up which i cannot remove!!!
Answer is C and E
correct
C and E
C and E is correct
Answer is C & E
C and E VMFS3 Datastores ESXi no longer supports VMFS3 datastores. The ESXi host automatically upgrades VMFS3 to VMFS5 when mounting existing datastores. The host performs the upgrade operation in the following circumstances: --------At the first boot after an upgrade to ESXi 7.0 or later, when the host mounts all discovered VMFS3 datastores. --------When you manually mount the VMFS3 datastores that are discovered after the boot, or mount persistently unmounted datastores. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-DAD74662-E09E-44A4-82F1-DB7A3433CEF9.html
CE is Correct
A D https://kb.vmware.com/s/article/78205 ESXi hosts running vSphere 6.0 or lower Distributed Virtual Switches running on version 6.0 or lower Host profiles based off an ESXi host running vSphere 6.0 or lower In vSphere 7.0, vCenter Server for Windows has been removed and support is not available. In vSphere 7.0, External Platform Services Controllers are removed.
Correct Answer is B & C A & D only impacts vCenter. E - with vSphere 7 host upgrade will migrate custom VIB. If any conflict occurs the host upgrade will fail so this only impact ESXi host and not VM.

new to here, unable to decide which one to take, it wort case if i go as its with the given answer without seeing the discussions will i able to pass? though low mark ok.
There are several questions were the wrong answers are marked. Therefore you should always check the discussions.
