Question 7

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?

A. Upgrade the virtual hardware

B. Migrate the VM to another host

C. Install VMware Tools

D. Restart vCenter

Correct 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 8

An administrator is tasked with implementing a backup solution capable of backing up the Supervisor cluster, vSphere Pods, and persistent volumes.
Which two solutions must be used to meet this requirement? (Choose two.)

A. VMware vCenter

B. Standalone Velero and Restic

C. NSX-T Manager

D. vSphere Host Client

E. Velero Plugin for vSphere

Correct Answer:BE

Question 9

An administrator is deploying a new all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA).
What is the minimum supported network throughput in Gb/s for each host?

A. 50

B. 10

C. 25

D. 1

Correct Answer:B
The minimum supported network throughput in Gb/s for each host in an all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA) is 10.

vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds.
ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA
all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6815-sub3

Question 10

An administrator is tasked with deploying a new on-premises software-defined data center (SDDC) that will contain a total of eight VMware vCenter instances.
The following requirements must be met:
• All vCenter instances should be visible in a single vSphere Client session.
• All vCenter inventory should be searchable from a single vSphere Client session.
• Any administrator must be able to complete operations on any vCenter instance using a single set of credentials.
What should the administrator configure to meet these requirements?

A. Two Enhanced Linked Mode groups consisting of four vCenter instances each in a Single Sign-On domain.

B. A single Hybrid Linked Mode group consisting of four vCenter instances each in a Single Sign-On domain.

C. A single Enhanced Linked Mode group consisting of eight vCenter instances in one Single Sign-On domain.

D. A single Hybrid Linked Mode group consisting of eight vCenter instances in one Single Sign-On domain.

Correct Answer:B
To meet the requirements of viewing and searching all vCenter instances and inventory with a single vSphere Client session and a single set of credentials, the administrator needs to configure a single Enhanced Linked Mode group consisting of eight vCenter instances in one Single Sign-On domain.

Question 11

An administrator is tasked with configuring remote direct memory access (RDMA) over Converged Ethernet v2 (RoCE v2).
Which two types of adapters must the administrator configure? (Choose two.)

A. Paravirtual RDMA adapter

B. RDMA network adapter

C. Software iSCSi adapter

D. Fibre Channel over Ethernet (FCoE) adapter

E. Software NVMe over RDMA storage adapter

Correct Answer:BD
ESXi 7 and later supports RoCE v2 technology, which enables RDMA over an Ethernet network. Hosts use an RDMA network adapter installed on the host and a software NVMe over RDMA storage adapter.

Question 12

An administrator is tasked with allowing a single user the ability to take snapshots on a virtual machine. When looking in vCenter, the administrator can see that there are already users and groups assigned permissions on the virtual machine as follows:
•The group VMJJsers has the Virtual Machine Power User role.
•The group VM_Viewers has the Read Only role.
The administrator confirms that the user requesting the additional access is currently one of five members of the VM_Viewers group
Which two steps should the administrator take to grant this user the additional access required without impacting the user access of others? (Choose two.)

A. Add the user to the VM_Users group and leave the permissions on the virtual machine object unchanged

B. Add a new permission on the virtual machine object selecting the user and the new custom role.

C. Edit the Read Only role to add the Virtual Machine Snapshot Management privileges.

D. Create a new custom role with the Virtual Machine Snapshot Management privileges.

E. new permission on the virtual machine object selecting the VM_Viewers group and the new custom

Correct Answer:BD
The administrator should create a new custom role with the Virtual Machine Snapshot Management privileges, which allows the user to create, delete and revert snapshots. The administrator should then add a new permission on the virtual machine object selecting the user and the new custom role, which grants the user the additional access required without affecting other users or groups.
