Question 1

An administrator receives reports from the application team of poor performance of a virtual ma-chine (VM). The administrator reviews the virtual machine and discovers that it has 20 snapshots that are over 12 months old.

What could the administrator do to improve the VM's performance?

Question 2

An administrator is tasked with adding two additional hosts into an existing production vSphere cluster to support the need for additional capacity.

The vSphere cluster currently has four identically configured ESXi hosts (esxOT esx02. esx03 and esx04) that utilize Intel Skylake-based CPUs. The two new hosts (esx05 and esx06) are configured identically in terms of memory and storage to the existing hosts: but utilize Intel Ice Lake-based CPUs.

The administrator must ensure that:

* Any virtual machine migrates to any of the six ESXi hosts running in the cluster.

* There is no virtual machine downtime during the process of adding the new hosts.

Which step should the administrator take to meet these requirements?



Answer : C

The step that the administrator should take to meet these requirements is to configure Enhanced vMotion Compatibility (EVC) mode on the existing cluster and add the two new hosts into the cluster. EVC mode allows migration of virtual machines between different generations of CPUs by masking unsupported processor features. EVC mode can be enabled on an existing cluster without affecting powered-on virtual machines.

Question 3

The vCenter inventory contains a virtual machine (VM) template called Linux-01. The administrator wants to install a software patch into Linux-01 while allowing users to continue to access Linux-01 to deploy VMs. Which series of steps should the administrator take to accomplish this task?



Answer : C

The administrator should clone Linux-01, which creates a copy of the virtual machine template. The administrator should then convert the clone to a VM, which allows the administrator to power on and modify the virtual machine. The administrator should then install the software patch on the VM, which updates the application. The administrator should then convert the VM back to a template, which preserves the changes made to the VM and allows users to deploy VMs from it.

Question 4

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?



Answer : C

The administrator can find log files containing information related to user login activities on the vCenter Server Appliance, which is a preconfigured Linux-based virtual machine that runs all vCenter Server services. The log files are located in /var/log/vmware/vmware-vpx/vpxd.log and /var/log/vmware/sso/ssoAdminServer.log directories. Reference: https://docs.vmware.com/en/VMware-vSphere/8.0/com.vmware.vsphere.troubleshooting.doc/GUID-5F9A7E49-5F9E-4F8A-BE6A-CAC5EE8E3734.html


Question 5

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.)



Answer : B, D

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.

Question 6

Following a merger with another company, an administrator is tasked with configuring an identity source for VMware vCenter so that all vSphere administrators can authenticate using their existing Active Directory accounts. Each company has user accounts in their own Active Directory forests.

The following additional information has been provided:

* The corporate policy states that only Windows-based machine accounts are allowed in Active Directory. Which action should the administrator take to configure vCenter Single Sign-On (SSO) to meet this requirement?



Answer : A

Integrated Windows Authentication is now depreciated (from v7). 'The Active Directory over LDAP identity source is preferred over the Active Directory (Integrated Windows Authentication) option.' https://kb.vmware.com/s/article/78506


Question 7

An administrator is asked to configure a security policy at the port group level of a standard switch.

The following requirements must be met:

* The security policy must apply to all virtual machines on portgroup-1.

* All traffic must be forwarded, regardless of the destination.



Answer : D

The security policy that must be configured at the port group level to allow all traffic to be forwarded regardless of the destination is promiscuous mode set to accept, which allows receiving all traffic on a virtual switch port.
