   An administrator is tasked with applying updates to a vSphere cluster running vSAN using vSphere Lifecycle Manager. Downtime to the ESXi hosts must be minimal while the work is completed. The administrator has already completed the following steps and no errors have been returned: Downloaded all applicable software and created a new image. Attached the new image to the cluster and run a compliance check against the image for the cluster. Ran a remediation pre-check for the cluster. Which two series of steps should the administrator perform to start the remediation of the cluster using the new image? (Choose two.)

   • A1. Use the Remediate option in vSphere Lifecycle Manager to remediate all of the ESXi hosts in the cluster in parallel. 2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts.
   • B1. Place each of the ESXi hosts into maintenance mode manually. 2. Use the Stage option in vSphere Lifecycle Manager to stage the required software on all ESXi hosts one at a time.
   • C1. Leave all ESXi hosts in the cluster operational. 2. Use the Stage All option in vSphere Lifecycle Manager to stage the required software onto all ESXi hosts one at a time.
   • D1. Leave all ESXi hosts in the cluster operational. 2. Use the Stage All option in vSphere Lifecycle Manager to stage the required software onto all ESXi hosts in the cluster in parallel.
   • E1. Use the Remediate option in vSphere Lifecycle Manager to remediate all of the ESXi hosts in the cluster in sequence. 2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts.

   Answer: DE

   Explanation

   DE D - In vSphere 8.0, staging exists as a separate operation that you can initiate. Staging is also automatically triggered when you remediate a cluster, a host in the cluster, or a standalone host. By default, vSphere Lifecycle Manager performs the staging operation onto all hosts in the cluster in parallel. E - You cannot remediate in parallel hosts in a vSAN cluster. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-lifecycle-manager/GUID-26EB282E-AD1E-425A-B4CF-1D70C0DE3C8F.html

   During the staging of a patch on a vCenter Server Appliance, an error was encountered and the process stopped. An administrator resolved the root cause and is ready to continue with the staging of the patch. From the vCenter Management Interface, which action should the administrator take to continue the process from the point at which the error occurred?

   • AUse the Stage and Install option to resume the staging.
   • BUse the Resume option to resume the staging.
   • CUse the Unstage option to restart the staging.
   • DUse the Stage Only option to restart the staging.

   Show answer

   Answer: B

   Explanation

   If vCenter Server encounters a problem staging the patches, the vCenter Server Management Interface displays the Resume button. Correct the problem preventing the patches from staging, and click Resume to finish staging the patches. The staging process resumes from the point at which vCenter Server encountered the problem.

   Refer to the exhibit.

   

   An administrator set up the following configuration: • The distributed switch has four ESXi hosts, and each host has two 10 Gbps NICs. • In the Network I/O Control configuration, the amount of bandwidth reserved for virtual machine (VM) traffic if 4 Gbps. The administrator wants to guarantee that VMs in the Retail distributed port group can access 50 percent of the available reserved bandwidth for VM traffic. Given this scenario, what should the size (in Gbps) of the Retail network resource pool be?

   • A40
   • B32
   • C8
   • D16

   Show answer

   Answer: D

   Explanation

   For anyone reading this in the future, the mistake is that each host has a pair of NICs. So you are multiplying by eight NICs, not four hosts.

4. Question 4 · 110 in bank

   Refer to the exhibit.

   

   An environment has the following configuration: 1. Resource Pool “RP-MOM” has a reservation of 6GHz and one running virtual machine (VM) “VM-M1” with 1 GHz reserved. 2. Resource Pool “RP-KID” has a reservation of 2GHz, and expandable reservations is activated. The administrator creates two VMs, “VM-K1” and “VM-K2”, in the “RP-KID” resource pool with 2GHz reserved for each, and turns on “VM-M1.” Given this scenario, which statement is true?

   • AThe administrator must deactivate expandable reservations to turn on VM-K2.
   • BThe administrator can create a third VM (“VM-K3”) at RP-KID and reserve 6GHz.
   • CVM-K2 can be powered on because it can get the resources needed from RP-MOM.
   • DVM-K2 cannot be powered on because there are not enough resources in RP-KID.

   Show answer

   Answer: C

   Explanation

   Key is expandable Expandable (default) The system considers the resources available in the selected resource pool and its direct parent resource pool. If the parent resource pool also has the Expandable Reservation option selected, it can borrow resources from its parent resource pool. Borrowing resources occurs recursively from the ancestors of the current resource pool as long as the Expandable Reservation option is selected. Leaving this option selected offers more flexibility, but, at the same time provides less protection. A child resource pool owner might reserve more resources than you anticipate

   Refer to the exhibit.

   

   An administrator is tasked with adding new capacity to an existing software-defined data center (SDDC). • The SDDC currently hosts two vSphere clusters (ClusterA and ClusterB) with different CPU compatibilities. • vSphere vMotion and vSphere Distributed Resource Scheduler (DRS) are currently in use in the SDDC. • The new capacity will be implemented by provisioning four ESXi hosts running a new generation of Intel Skylake CPUs. • All workload virtual machines (VMs) must support live migration to any cluster in the SDDC. The administrator noticed the running critical "evc1" virtual machine (VM) shown in the exhibit is not migrating using vSphere vMotion to the original Clusters A or B. Which three steps must the administrator take to support this functionality? (Choose three.)

   • ADisable the Enhanced vMotion Compatibility (EVC) on the VM.
   • BReboot the VM.
   • CConfigure the Enhanced vMotion Compatibility (EVC) on the VM to Intel Skylake.
   • DPower on the VM.
   • EConfigure the Enhanced vMotion Compatibility (EVC) on vSphere Cluster A and B to sup-port Intel Skylake.
   • FPower off the VM.

   Show answer

   Answer: ADE

   Explanation

   Looking exhibit the VM is already Powered Off so B and F are not correct also EVC are already Enabled so C are not correct so probably correct answers are A D E

   An administrator has a requirement to revert a running virtual machine to a previous snapshot af-ter a failed attempt to upgrade an application. When the administrator originally took the snap-shot, the following choices in the Take Snapshot dialog were made: • Snapshot the virtual machine’s memory = false • Quiesce guest file system = false What will be the result of the administrator selecting the “Revert to Latest Snapshot” option to return the virtual machine to a previous snapshot? (Choose two.)

   • AThe virtual machine will be restored to the parent snapshot
   • BThe virtual machine will be restored in a powered off state.
   • CThe virtual machine will be restored to the child snapshot
   • DThe virtual machine will be restored in a powered on state.
   • EThe virtual machine will be restored in a suspended state.

   An administrator is tasked with configuring certificates for a VMware software-defined data center (SDDC) based on the following requirements: • The solution should minimize the ongoing management overhead of replacing certificates. • No intermediate certificate authorities are allowed in the certificate chain. • All external traffic should be secured using certificates signed by an Enterprise Certificate Authority (CA). Which two actions should the administrator take to ensure the solution meets corporate policy? (Choose two.)

   • AReplace the solution user certificates with custom certificates generated from the Enterprise CA.
   • BReplace the machine SSL certificates with custom certificates generated from the Enterprise CA.
   • CReplace the machine SSL certificates with self-signed certificates generated from the VMware Certificate Authority (VMCA).
   • DReplace the VMware Certificate Authority (VMCA) certificate with a custom certificate gen-erated from the Enterprise CA.
   • EReplace the solution user certificates with self-signed certificates generated from the VMware Certificate Authority (VMCA).

    Refer to the exhibit.

    

    Given the configuration shown in the exhibit, what must the administrator do to delete only the latest version of the template?

    • AIn the SA-Templates folder, rename App-LibTemplate (2) to App-LibTemplate (4).
    • BCheck out App-LibTemplate (3) and delete the template from the SA-Templates folder.
    • CDelete App-LibTemplate (3) from the SA-Templates folder.
    • DRevert to App-LibTemplate (2) and delete App-LibTemplate (3).

    Show answer

    Answer: D

    Explanation

    D. Revert to App-LibTemplate (2) and delete App-LibTemplate (3). The exhibit likely shows multiple versions of a template within a versioned content library in VMware vSphere. Versioning ensures that templates can be updated while retaining older versions for rollback purposes. Deleting the Latest Version (App-LibTemplate (3)): VMware’s content library requires that the current version of a template be reverted to the previous version before the latest version can be deleted. This prevents accidental deletion of the latest version without first confirming the need to roll back to an older state. Steps to Delete the Latest Version: Revert to App-LibTemplate (2), which will make it the active version. After reverting, App-LibTemplate (3) becomes a historical version and can then be safely deleted.
