Question 1 of 94

An administrator is installing a Platform Services Controller Instance.
Which two options are available during the installation process? (Choose two.)

choose deployment size

specify vSphere administrator credentials

enable Enhanced Linked Mode

create a vCenter Single sign-on domain

join an existing domain

Correct Answer: D, E

When installing a Platform Services Controller (PSC) instance, you have the options to create a vCenter Single Sign-On (SSO) domain and to join an existing domain. Creating a vCenter SSO domain allows the PSC to manage multiple vSphere components securely. Joining an existing domain integrates the PSC instance into an already configured domain, enabling linked mode for managing multiple vCenters. These options are critical for setting up and extending a vSphere environment efficiently.

Question 2 of 94

A vSphere Administrator has multiple virtual machines running on a VMFS datastore.
Which option prioritizes the disk access for the virtual machines?

Disk Shares

Disk Mode

Disk Type

Hard Disk

Correct Answer: A

Disk Shares is the correct option. In a VMware vSphere environment, disk shares are used to prioritize disk access among virtual machines. By assigning different share values, a vSphere administrator can control the relative priority of disk input/output (I/O) operations for virtual machines that share the same datastore, ensuring that more important virtual machines receive appropriate resources over less critical ones.

Question 3 of 94

An administrator has an environment with these conditions and requirements:
✑ The host provides 6GHz of CPU and 32GB of memory
✑ The host is shared between the Marketing and QA departments
✑ The QA department needs a higher compute resource priority
How can the administrator meet the conditions and requirements?

Adjust NIOC or SIOC as appropriate to give the QA department a higher compute priority within the cluster.

Create a resource pool for each department and use the Shares attribute to prioritize the allocation of resource.

Assign affinity or anti-affinity rules to the appropriate VMs for each department.

Set the VM priority to high for QA department VMs and normal for Marketing department VMs.

Correct Answer: B

The best way to meet the conditions and requirements is to create a resource pool for each department and use the Shares attribute to prioritize the allocation of resources. This approach allows the administrator to allocate a higher priority for compute resources to the QA department while maintaining control over the distribution of resources between the Marketing and QA departments. Adjusting NIOC or SIOC and setting VM priorities are not the correct approaches as they do not achieve the required prioritization within a shared host environment effectively. Affinity rules are used more for VM placement rather than setting resource priorities.

Question 4 of 94

What is a benefit of using resource pools?

Increased visibility of user activity

Increased vMotion efficiency for a set of VMs

Increased accuracy for proactive resources for a set of VMs

Increased ease of reserving resources for a set of VMs

Correct Answer: D

Resource pools help in organizing and simplifying the management of resources by allowing administrators to easily allocate and reserve resources for a specific set of Virtual Machines (VMs). This increased ease of reserving resources is particularly beneficial in environments where specific resource allocation and prioritization are necessary.

Question 5 of 94

This error is generated when a vSphere administrator takes a VM snapshot:
An error occurred while taking a snapshot: Failed to quiesce the virtual machine
What should the administrator investigate to determine the cause of the failure?

Check if the virtual machine is already running on snapshots.

Check if the virtual machine is in suspended state.

Check if VMware Tools is installed on virtual machine.

Check if the virtual machine has an ISO mounted.

Correct Answer: C

The error message 'Failed to quiesce the virtual machine' indicates that the process of quiescing, which is typically performed by VMware Tools to prepare the virtual machine for snapshotting, has failed. Therefore, the most pertinent action is to check if VMware Tools is installed on the virtual machine, as this is a necessary component for the quiescing process during snapshot creation.
