Question 1

An administrator is preparing to perform an update to vSphere clusters that are running vSAN. The administrator wants to ensure that the following requirements are met as part of the update:

* All hosts in the cluster are updated with the same software.

* The firmware versions on the hosts are updated

* The new software versions are checked for compliance against the vSAN Hardware Compatibility List.

Which three steps should the administrator take to meet these requirements? (Choose three.)



Answer : A, B, E

The administrator should take these three steps to perform an update to vSphere clusters that are running vSAN:

Configure vSphere Lifecycle Manager with an image for the cluster, which allows the administrator to specify the desired ESXi version and firmware for the hosts in the cluster.

Register the vendor hardware management system as a vCenter Server extension, which allows the administrator to update the firmware on the hosts using vSphere Lifecycle Manager. The vendor hardware management system can also provide the firmware updates to vSphere Lifecycle Manager, so there is no need to download them from the vendor website separately.

Run a hardware compatibility check using vSphere Lifecycle Manager, which verifies that the new software and firmware versions are compatible with the vSAN Hardware Compatibility List.


Question 2

An administrator is responsible for performing maintenance tasks on a vSphere cluster. The cluster has the following configuration:

. Identically configured vSphere ESXi hosts (esx01, esx02, esx03 and esx04)

* All workloads are deployed into a single VMFS datastore provided by the external storage array

* vSphere High Availability (HA) has not been enabled

* vSphere Distributed Resource Scheduler (DRS) has not been enabled

Currently, a critical production application workload (VM1) is running on esx01.

Given this scenario, which two actions are required to ensure VM1 continues to run when esx01 is placed into maintenance mode? (Choose two.)



Answer : A, D

Two actions that are required to ensure VM1 continues to run when esx01 is placed into maintenance mode are enabling fully automated DRS on the cluster, which allows balancing the workload across hosts and migrating VMs without user intervention; and manually live migrating VM1 to another host within the cluster using vSphere vMotion, which allows moving a running VM without downtime.


Question 3

Which feature would allow for the non-disruptive migration of a virtual machine between two clusters in a single VMware vCenter instance?



Answer : A

vSphere vMotion allows for the non-disruptive migration of a virtual machine between two clusters in a single vCenter instance, as long as there is shared storage and network connectivity between the clusters.


vMotion is used to move the VM to a different cluster within the same vCenter. This only works if both clusters share the same storage. If they don't you also need to perform a Storage vMotion. Cross vCenter Migration is only used to migrate to a different vCenter.

Question 4

An administrator needs better performance and near-zero CPU utilization from the ESXI hosts for networking functions and processing. The administrator creates a new vSphere Distributed Switch and enables network offloads compatibility.

Which solution would help achieve this goal?



Answer : B

The solution that would help achieve better performance and near-zero CPU utilization from the ESXi hosts for networking functions and processing is Data Processing Units (DPUs), which are specialized processors that offload network services from the CPU and provide hardware acceleration.

Question 5

An administrator is adding a new ESXi host to an existing vSphere cluster. When selecting the cluster, the administrator Is unable to use the Cluster Quickstart workflow to add and configure the additional host.

What could be the root cause of this issue?



Answer : A

Option A is correct because it indicates that the administrator has previously dismissed the Cluster Quickstart workflow, which will prevent them from using it to add and configure an additional host. To use the Cluster Quickstart workflow again, the administrator must enable it in the cluster settings. Option B is incorrect because the administrator does not need to manually add the host to the cluster before using the Cluster Quickstart workflow, as this is one of the steps in the workflow. Option C is incorrect because the administrator does not need any special permissions to use the Cluster Quickstart workflow, as long as they have permissions to perform cluster operations. Option D is incorrect because there is no option to enable the Cluster Quickstart workflow in VMware vCenter, as this is a feature of vSphere clusters.

Question 6

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?



Answer : C

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.


Question 7

An administrator needs to configure a content library solution based on the following information:

* A new corporate virtual machine (VM) template is created every month to include all of the latest patches.

* The new VM template should be downloaded from the primary data center site (London) to two secondary data center sites (Tokyo and New York) as soon as possible.

* There is limited disk space available at one of the secondary data center sites (Tokyo) due to an ongoing data center consolidation project.

Which four steps should the administrator take to configure the content library solution before adding a VM template? (Choose four.)



Answer : B, D, E, G

The administrator should take these four steps to configure the content library solution before adding a VM template:

Create a new published content library at the primary site, which allows the administrator to share the VM template with other sites.

Configure the New York subscribed content library to download content immediately, which ensures that the new VM template is downloaded from the primary site as soon as possible.

Configure the Tokyo subscribed content library to download content when needed, which saves disk space at the secondary site by downloading only the metadata of the VM template until it is deployed.

Create a new subscribed content library in each secondary site, which allows the administrator to subscribe to the published content library at the primary site and synchronize the VM template.
