An administrator needs to update a VMware vCenter instance to a newer minor release version. Due to restrictions within the environment, the vCenter instance does not have access to the Internet As a first step, the administrator downloads the required update on another machine.


What are the next steps the administrator must perform to complete the update?

A Place the update ISO file in a Virtual Machine File System (VMFS) datastore.
Use the vSphere Client to select the update ISO file as the source for the update.


A.

Place the update ISO file in a Virtual Machine File System (VMFS) datastore.
Use the vSphere Client to select the update ISO file as the source for the update


B.

Mount the ISO update file to the CD-ROM drive of the vCenter instance
Use the vCenter Management Interface to select the CD-ROM as the source for the update


C.

Place the ISO update file in a folder accessible to the vCenter instance over HTTPS.
Use the vCenter Management Interface to select the update file as the source for the update


D.

Place the ZIP update file in a folder accessible to the vCenter instance over HTTPS Use the vSphere Client to select the update file as the source for the update.





B.
  

Mount the ISO update file to the CD-ROM drive of the vCenter instance

An administrator creates a virtual machine that contains the latest company-approved software, tools and security updates. Company policy requires that only full clones are allowed for server workloads.

A combination of which two tasks should the administrator complete to prepare for the deployment of this virtual machine for multiple users? (Choose two.)


A.

Set appropriate permissions on the virtual machine.


B.

Create a virtual machine customization specification.


C.

Upgrade the virtual hardware.


D.

Convert the virtual machine to a template.


E.

Take a snapshot of the virtual machine.





B.
  

Create a virtual machine customization specification.



D.
  

Convert the virtual machine to a template.



Option B and D are correct because they allow the administrator to create a virtual machine customization specification, which can be used to customize guest operating system settings for multiple virtual machines, and convert the virtual machine to a template, which can be used to create full clones of server workloads. Option A is incorrect because assigning appropriate permissions on the virtual machine does not prepare it for deployment for multiple users. Option C is incorrect because upgrading the virtual hardware does not prepare it for deployment for multiple users. Option E is incorrect because taking a snapshot of the virtual machine does not prepare it for deployment for multiple users.

Which step is completed during Stage 1 of the vCenter Server Appliance deployment?


A.

Join a vCenter Single Sign-On domain


B.

Create a new vCenter Single Sign-On domain


C.

Select the deployment size


D.

Configure SSH access





C.
  

Select the deployment size



The minimum network throughput in Gb/s for vSAN using the Express Storage Architecture (ESA) is 1 Gb/s, which is the minimum requirement for vSAN network adapters. However, VMware recommends using 10 Gb/s or higher for better performance and reliability.

Which two tasks can be completed using vSphere LifeCycle Manager? (Choose two.)


A.

Manage the firmware lifecycle of ESXi hosts that are part of a managed cluster with a single image.


B.

Check that the ESXi hosts are compliant with the recommended baseline and update the hosts


C.

Upgrade VMware vCenter from version 7 to 8.


D.

Check the hardware compatibility of the hosts in a cluster against the VMware Compatibility Guide (VCG) using baselines.


E.

Manage the firmware lifecycle of ESXi hosts are part of a managed cluster using baselines





B.
  

Check that the ESXi hosts are compliant with the recommended baseline and update the hosts



E.
  

Manage the firmware lifecycle of ESXi hosts are part of a managed cluster using baselines



A group of new virtual machines have been deployed using thin-provisioned disks due to the limited storage space available in an environment. The storage team has expressed concern about extensive use of this type of provisioning.
An administrator is tasked with creating a custom alarm to notify the storage team when thin provisioning reaches a certain capacity threshold.
Where must the administrator define this alarm?


A.

Datastore


B.

Data center


C.

Datastore cluster


D.

Virtual machine





A.
  

Datastore



Explanation
To create a custom alarm to notify when thin provisioning reaches a certain capacity threshold, the administrator must define this alarm at the datastore level, as it is related to datastore usage.

An administrator is tasked with configuring vSphere Trust Authority. The administrator has completed the following steps:

• Set up the workstation
• Enabled the Trust Authority Administrator
• Enabled the Trust Authority State
• Collected information about the ESXi hosts and vCenter to be trusted

A.

Import the Trusted Host information to the Trust Authority Cluster


B.

Import the Trusted Cluster information to the Trusted Hosts

An administrator Is performing maintenance activities and discovers that a Virtual Machine File System (VMFS) datastore has a lot more used capacity than expected. The datastore contains 10 virtual machines (VMs) and, when the administrator reviews the contents of the associated datastore, discovers that five- virtual machines have a snapshot file (-delta.vmdk flies) that has not been modified In over 12 months. The administrator chei kfl the Snapshot Manager within the vSphere Client and confirms that there are no snapshots visible.
Which task should the administrator complete on the virtual machines to free up datastore space?


A.

Consolidate the snapshots for each VM.


B.

Inflate the disk files for each VM.


C.

Delete all snapshots for each VM.


D.

Storage vMotion each VM to another datastore.





A.
  

Consolidate the snapshots for each VM.



Consolidating snapshots for each VM will merge any snapshot files that are not associated with a snapshot in Snapshot Manager into the base disk file and free up datastore space.

The presence of redundant delta disks can adversely affect the virtual machine performance. You can combine such disks without violating a data dependency. After consolidation, redundant disks are removed, which improves the virtual machine performance and saves storage space.

An administrator is investigating user logon failures for a VMware vCenter instance
Where can the administrator find log files containing information related to user login activities?

On the vCenter Management Interface


B.

On the ESXi host using the Direct Console User Interface (®)


C.

On the vCenter Server Appliance


D.

In the vSphere Client when viewing the vCenter virtual machine





C.
