2V0-21.23: Professional VMware vSphere 8.x
An administrator set up the following configuration:
The distributed switch has three ESXi hosts, and each host has two 40 Gbps NICs.
The amount of bandwidth reserved for virtual machine (VM) traffic is 6 Gbps.
The administrator wants to guarantee that VMs in the Finance 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 Finance network resource pool be?
18
80
36
120
Answer is 18
VMs in the Finance distributed port group can access 50 percent of the available reserved bandwidth for VM traffic, the size of the Finance network resource pool should be 50 percent of the reserved bandwidth for VM traffic, which is 6 Gbps x 3 hosts = 18 Gbps

An administrator has mapped three vSphere zones to three vSphere clusters.
Which two statements are true for this vSphere with Tanzu zonal Supervisor enablement? (Choose two.)
One Supervisor will be created in a specific zone.
One Supervisor will be created across all zones.
Three Supervisors will be created in Linked Mode.
Individual vSphere Namespaces will be placed into a specific zone.
Individual vSphere Namespaces will be spread across all zones.
Answers are;
B. One Supervisor will be created across all zones.
E. Individual vSphere Namespaces will be spread across all zones.
In a three-zone deployment, all three vSphere clusters become one Supervisor.
In a three-zone Supervisor, a namespace resource pool is created on each vSphere cluster that is mapped to a zone. The namespace spreads across all three vSphere clusters in each zone.

Which deployment size should the administrator select?
Medium
Tiny
Large
Small
Answer is Small
Tiny (10 hosts 100 VMs): 2 vCPUs & 14GB RAM
Small (100 hosts 1000 VMs): 4 vCPUs & 21GB RAM
Medium (400 hosts 4000 VMs): 8 vCPUs & 30GB RAM
Large (1000 hosts 10000 VMs): 16 vCPUs & 39GB RAM
X-Large (2000 hosts 35000 VMs): 24 vCPUs & 58GB RAM

They must have a supported Wide Area Network (WAN).
They must have a minimum of a 10 Gbps network adapter.
They must have a minimum of a 1 Gbps network adapter.
Network latency must be more than 10 milliseconds.
Answers are;
A. Network latency must be less than 10 milliseconds. D. They must have a minimum of a 1 Gbps network adapter.
Network latency between the Active, Passive, and Witness nodes must have less than 10 milliseconds and a minimum of a 1 Gbps network.

An administrator is deploying a new all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA).
What is the minimum supported network throughput in Gb/s for each host?
50
10
25
1
Answer is 10
OSA requires a minimum of 10Gbps bandwidth while requires a 25Gbs bandwidth.

An administrator has a host profile named Standard-Config. The administrator wants to change the other host profiles to use only the storage configuration settings that are defined in the Standard-Config host profile.
What should the administrator do to make this change?
Export host customizations and import them to the other host profiles.
Copy the storage settings from Standard-Config to all other host profiles.
Duplicate the Standard-Config host profile and only modify the storage configuration settings.
Export the Standard-Config host profile and attach it to tile other hosts.
Answer is Copy the storage settings from Standard-Config to all other host profiles.
Option B allows the administrator to copy the storage settings from the "Standard-Config" host profile directly to all other host profiles. This ensures that the storage configuration settings are applied uniformly across all host profiles without affecting other settings.
Option A is incorrect because exporting host customizations doesn't address modifying host profiles with specific storage settings.
Option C is incorrect because duplicating the "Standard-Config" host profile would create a new host profile with all settings, not just the storage settings, and it would not affect the other existing host profiles.
Option D is incorrect because attaching the "Standard-Config" host profile to other hosts doesn't modify their existing host profiles to use the storage configuration settings defined in the "Standard-Config" profile.

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.
Answers are;
B. Create a virtual machine customization specification.
D. Convert the virtual machine to a template.
The question only speaks of what the administrator needs to do and prepare virtual machine for multiple users, so (A) permissions has nothing to do with it Upgrading virtual hardware (C) is a nice to have if required but not necessary taking a snapshot (E) will not prepare the VM. D kind of explains itself, B will allow you to customize the VM and avoid issues that come with just cloning such as repeated IPs, Macs, having the same hostname, etc, its the best practice.
An administrator is adding a new ESXi host to an existing vSphere cluster. When selecting the cluster, the administrator is unable to use the Cluster Quickstart workflow to add and configure the additional host.
What could be the root cause of this issue?
The administrator has previously dismissed the Cluster Quickstart workflow.
The administrator must manually add the host to the cluster before using the Cluster Quickstart workflow.
The administrator has not been assigned the required permissions to use the Cluster Quickstart workflow.
The administrator must enable the Cluster Quickstart workflow option in VMware vCenter.
Answer is The administrator has previously dismissed the Cluster Quickstart workflow.
You can use the Skip Quickstart button to exit the Quickstart workflow, and continue configuring the cluster and its hosts manually. You can add new hosts individually, and manually configure those hosts. Once skipped, you cannot restore the Quickstart workflow for the cluster.

If a distributed switch uses the “Route based on physical NIC load” load balancing algorithm, what does the mean send or receive utilization of an uplink need to exceed for the flow of traffic to move to the second uplink?
75 percent of the capacity over a 30 second period
60 percent of the capacity over a 30 second period
60 percent of the capacity over a 40 second period
75 percent of the capacity over a 40 second period
Answer is 75 percent of the capacity over a 30 second period
The distributed switch calculates uplinks for virtual machines by taking their port ID and the number of uplinks in the NIC team. The distributed switch tests the uplinks every 30 seconds, and if their load exceeds 75 percent of usage, the port ID of the virtual machine with the highest I/O is moved to a different uplink.
