VMware 2V0-21.23 Online Questions &
Answers
Question 161:
A virtual machine with a single 100 GB virtual machine disk file has a single 20 GB snapshot. The virtual machine is powered off.
How much additional free space on the datastore is required to delete the snapshot, committing the snapshot delta disk to the base disk? (Choose the best answer.)
A. 0 GB B. 100 GB C. 20 GB D. 120 GB
A. 0 GB
Question 162:
An administrator is configuring vSphere Lifecycle Manager to install patches to a vSphere cluster. The cluster runs workload virtual machines (VMs) that are incompatible with vSphere vMotion, and therefore cannot be live migrated between hosts during the installation of the patches.
Which configuration in vSphere Lifecycle Manager will allow the administrator to reduce the downtime associated with the patching operation without migrating the VMs?
A. Enable Distributed Power Management (DPM) and set the VM power state to the suspend to disk option B. Enable Quick Boot and set the VM power state to the suspend to disk option C. Enable vSphere High Availability (HA) admission control and set the VM power state to the suspend to memory option D. Enable Quick Boot and set the VM power state to the suspend to memory option
D. Enable Quick Boot and set the VM power state to the suspend to memory option
Explanation/Reference:
https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-lifecycle- manager/GUID-06A5D316-9452-4A5D-A5BB-3AEEFE0483B4.html The administrator should enable Quick Boot and set the VM power state to the suspend to memory option, which will allow the administrator to reduce the downtime associated with the patching operation without migrating the VMs. Quick Boot is a feature that skips the hardware initialization phase during host reboot, which reduces the system boot time. Suspend to memory is an option that preserves the state of the VMs in the host memory and restores them from memory after the reboot, which minimizes the VM downtime. These two features work together to optimize the remediation process and speed up the patching operation.

Question 163:
An administrator is utilizing Network I/O Control (NIOC) to allocate bandwidth utilization on a physical 10 Gbps adapter. What is the maximum amount of bandwidth that can be reserved? (Choose the best answer.)
An administrator plans to bring VMware vCenter offline in order to perform hardware mainte-nance on the host where the vCenter Server Appliance is running.
Which vSphere feature must be configured to ensure that vCenter users experience minimal downtime?
A. vSphere Distributed Resource Scheduler B. Hybrid Linked Mode C. vCenter Server High Availability D. Enhanced Linked Mode
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/Reference:
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.

Question 166:
An administrator remotely deploys VMware ESXi using an out of band management connection and now needs to complete the configuration of the management network so that the host is accessible through the vSphere Host Client.
The following information has been provided to complete the configuration: Host FQDN esxi01corp.local Management VLAN ID: 10 DHCP: No Management IP Address: 172.16.10.101/24 Management IP Gateway: 172.16.10.1 Corporate DNS Servers: 172 16.10.5, 172.16.10..6 DNS Domain: corp.local
In addition, all host configurations must also meet the following requirements:
The management network must use only IPv4 network protocols.
The management network must be fault tolerant
Which four high level tasks should the administrator complete in the Direct Console User Interface (DCUI) in order to meet the requirements and successfully log into the vSphere Host Client? (Choose four.)
A. Set the value of the VMware ESXi Management Network VLAN ID to 10 B. Configure at least two network adapters for the VMware ESXi Management Network C. Update the VMware ESXi Management Network IPv4 configuration to use a static IPv4 address D. Create a DNS A Record for the VMware ESXi host on the corporate DNS servers E. Disable IPv6 for the VMware ESXi Management Network F. Restore the original Management vSphere Standard Switch. G. Update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for ' names resolution
A. Set the value of the VMware ESXi Management Network VLAN ID to 10 B. Configure at least two network adapters for the VMware ESXi Management Network C. Update the VMware ESXi Management Network IPv4 configuration to use a static IPv4 address D. Create a DNS A Record for the VMware ESXi host on the corporate DNS servers

Question 167:
An administrator is tasked with looking into the disaster recovery options for protecting a database server using VMware vSphere Replication.
The following requirements must be met:
The virtual machine must remain online during the protection.
The virtual machine's snapshots must be used as part of the replication process.
Which step must the administrator complete to accomplish this task?
A. Configure the virtual machine storage policy. B. Enable guest OS VSS quiescing for this virtual machine. C. Perform a full initial synchronization of the source virtual machine to the target location. D. Configure network traffic isolation for vSphere Replication.
C. Perform a full initial synchronization of the source virtual machine to the target location.
A VMkernel port is labelled PROD01 and uses the default TCP/IP stack. Currently, this VMkernel port is configured for supporting live virtual machine (VM) migrations.
Which configuration change should the administrator make to isolate live VM migration traffic from other network traffic?
A. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion. B. Remove PROD01 and create a new VMkernel port with the TCP/IP stack set to provisioning. C. Create a new VMkernel port and set the TCP/IP stack to provisioning. D. Modify PROD01 by changing the TCP/IP stack to vSphere vMotion.
A. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion.
Explanation/Reference:
Select a TCP/IP stack from the list. Once you set a TCP/IP stack for the VMkernel adapter, you cannot change it later. If you select the vMotion or the Provisioning TCP/IP stack, you will be able to use only these stacks to handle vMotion or Provisioning traffic on the host. All VMkernel adapters for vMotion on the default TCP/IP stack are disabled for future vMotion sessions. If you set the Provisioning TCP/IP stack, VMkernel adapters on the default TCP/IP stack are disabled for operations that include Provisioning traffic, such as virtual machine cold migration, cloning, and snapshot migration.
What is a requirement of Storage I/O Control? (Choose the best answer.)
A. Storage connected through Fibre Channel B. Management by a single vCenter Server C. Datastores with multiple extents D. Automated storage tiering capabilities
What are two use cases for VMware vSphere+? (Choose two.)
A. Enhance on-premises workloads by managing them through the VMware Cloud Console B. Allow live migration between on-premises and VMware Cloud C. Increase the performance of the native vCenter vMotion capability D. Allow the creation of affinity and anti-affinity rules to be used during failover events E. Simplify vCenter lifecycle management through cloud-enabled automation
A. Enhance on-premises workloads by managing them through the VMware Cloud Console E. Simplify vCenter lifecycle management through cloud-enabled automation
