An administrator manually configures a reference ESXi host that meets company security standards for vSphere environments. The administrator now needs to apply all of the security standards to every identically configured host across multiple vSphere clusters within a single VMware vCenter instance.

Which four steps would the administrator complete to meet this requirement? (Choose four.)

Extract the host profile from the reference host
Export the host profile from vCenter.
Import host customization on the reference host.
Attach the host profile to each cluster that requires the secure configuration.
Check the compliance of each host against the host profile.
Reset host customization on the reference host.
Remediate all non-compliant hosts.

Correct answer: ADEG

Explanation:

To apply the security standards from a reference host to other hosts across multiple clusters, the administrator needs to extract a host profile from the reference host, which captures its configuration settings; attach the host profile to each cluster that requires the same configuration; check the compliance of each host against the host profile, which compares their settings; and remediate all non-compliant hosts, which applies the configuration settings from the host profile.References:https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-F8F105EC-A6EA-4

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.)

Set appropriate permissions on the virtual machine.
Create a virtual machine customization specification.
Upgrade the virtual hardware.
Convert the virtual machine to a template.
Take a snapshot of the virtual machine.

Correct answer: BD

Explanation:

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.

An administrator has a requirement to revert a running virtual machine to a previous snapshot after a failed attempt to upgrade an application. When the administrator originally took the snapshot, 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.)

The virtual machine will be restored to the parent snapshot
The virtual machine will be restored in a powered off state
The virtual machine will be restored to the child snapshot
The virtual machine will be restored in a powered on state
The virtual machine will be restored in a suspended state

Correct answer: AB

An administrator is tasked with configuring remote direct memory access (RDMA) over Converged Ethernet

Which two types of adapters must the administrator configure? (Choose two.)

Paravirtual RDMA adapter
RDMA network adapter
Software iSCSi adapter
Fibre Channel over Ethernet (FCoE) adapter
Software NVMe over RDMA storage adapter

Correct answer: BE

Explanation:

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.https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-storage/GUID-F4B42510-9E6D-4446-816A-501286

An administrator is asked to segregate virtual machine (VM) traffic by VLAN on a vSphere standard switch

The following requirements must be met:

VLAN ID on the switch port group must be 4095.
VLAN tagging must be done at the VM level.

Which tagging mode is required?

External Switch Tagging (EST)
None
Virtual Guest Tagging (VGT)
Virtual Switch Tagging (VST)

Correct answer: C

Explanation:

The tagging mode that is required is Virtual Guest Tagging (VGT), which allows VLAN tagging to be done at the VM level. VGT requires that the VLAN ID on the switch port group be set to 4095, which is a special value that indicates that packets from all VLANs are allowed to pass through.

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?

Use the Stage and Install option to resume the staging.
Use the Resume option to resume the staging.
Use the Unstage option to restart the staging.
Use the Stage Only option to restart the staging.

Correct answer: B

Perfmon
df
esxtop
vSphere Client

Correct answer: AC

Which three features are only available when using vSphere Distributed Switches instead of vSphere Standard Switches? (Choose three.)

802.1Q tagging
Port mirroring
Netflow
Configuration backup and restore
IPv6 support
IPv4 support

Correct answer: BCD

Explanation:

Three features that are only available when using vSphere Distributed Switches instead of vSphere Standard Switches are port mirroring, which allows monitoring network traffic on a virtual switch port; Netflow, which allows collecting IP traffic information from a virtual switch; and configuration backup and restore, which allows saving and restoring distributed switch settings.References:https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-D5960C77-0D1https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-A59628EA-985https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-E9EB9D18-692

An administrator needs to consolidate a number of physical servers by migrating the workloads to a software-defined data center solution.

Which VMware solution should the administrator recommend?

VMware Horizon
VMware vSAN
VMware vSphere
VMware

Correct answer: C

Explanation:

Option C is correct because VMware vSphere is the solution that provides a software-defined data center platform that can consolidate physical servers by migrating the workloads to virtual machines. Option A is incorrect because VMware Horizon is a solution for virtual desktop infrastructure (VDI) and application delivery. Option B is incorrect because VMware vSAN is a solution for software-defined storage that is integrated with vSphere. Option D is incorrect because VMware NSX is a solution for software-defined networking that is integrated with vSphere. References: https://www.vmware.com/products/vsphere.html

What are two uses cases for VMware Tools? (Choose two.)

Time synchronization with an NTP server
Direct deployment of the Aria Automation Config minion
Share folders between ESXi hosts and guest OS file systems
Ability to shut down a virtual machine remotely
Support for unsupported network device drivers

Correct answer: BD

Explanation:

https://www.stevenbright.com/2022/03/deploy-salt-minions-automatically-using-vmware-tools/Two use cases for VMware Tools are direct deployment of the Aria Automation Config minion and ability to shut down a virtual machine remotely. Direct deployment of the Aria Automation Config minion is a feature that allows the administrator to deploy a configuration management agent to a virtual machine using VMware Tools. This feature enables automation and orchestration of virtual machine configuration tasks. Ability to shut down a virtual machine remotely is a feature that allows the administrator to gracefully power off a virtual machine from the vSphere Client or other VMware products. This feature requires VMware Tools to be installed and running on the guest operating system.
