VMware 2V0-621D Dumps Questions 2021

NEW QUESTION 1
An administrator needs to migrate a legacy physical application server to a virtual machine within a vSphere 6 cluster. As part of the conversion, the administrator must reduce the size of the virtual disks.
What action should the administrator take to create a virtual machine with smaller virtual disks than the original physical server?

• A. Shut down the physical server and use VMware Converter cold cloning with volume- based cloning at the disk level.
• B. Use VMware Converter hot cloning with volume-based cloning at the block level.
• C. Shut down the physical server and use VMware Converter cold cloning with volume- based cloning at the file level.
• D. Use VMware Converter hot cloning with volume-based cloning at the file level.

Answer: D

Explanation: Use VMware converter hot cloning with volume-based cloning at the file level to create a virtual machine with smaller virtual disks.

NEW QUESTION 2
An administrator is troubleshooting a CPU issue for a virtual machine. The following is seen in esxtop:
✑ CPU0 is at 100% usage
✑ The remaining logical CPUs are close to 0%
✑ %RDY value is consistently above 10%
What is likely the cause of the CPU issue?

• A. The virtual machine has a CPU limit configured.
• B. The virtual machine’s guest operating system is configured for SMP.
• C. The virtual machine has CPU affinity configured.
• D. The virtual machine is configured with a CPU reservation.

Answer: C

Explanation: By setting a CPU affinity on the virtual machine you are limiting the available CPUs on which the virtual machine can run. It does not dedicate that CPU to that virtual machine and therefore does not restrict the CPU scheduler from using that CPU for other virtual machines.

NEW QUESTION 12
In a vSphere High Availability cluster, what is the VM Monitoring I/O stats interval default value?

• A. 60 seconds
• B. 90 seconds
• C. 120 seconds
• D. 180 seconds

Answer: C

Explanation: Occasionally, virtual machines or applications that are still functioning properly stop sending heartbeats. To avoid unnecessary resets, the VM Monitoring service also monitors a virtual machine's I/O activity. If no heartbeats are received within the failure inter’al, the I/O stats interval (a cluster-level attribute) is checked. The I/O stats interval determines if any disk or network activity has occurred for the virtual machine during the previous two minutes (120 seconds). If not, the virtual machine is reset. This default value (120 seconds) can be changed using the advanced attribute das.iostatsinterval.

NEW QUESTION 17
A user notifies an administrator that Content Libraries are not visible. What is a possible solution?

• A. Assign the user the read-only role at the global permission level.
• B. Assign the user the read-only role at the vCenter Server root level.
• C. Assign the user the read-only role at the vCenter Server data center level.
• D. Assign the user the read-only role at the vCenter Server cluster level.

Answer: A

Explanation: The direct parent for content libraries is the global root. This means that if you set a permission at a vCenter Server level and propagate it to the children objects, the permission applies to data centers, folders, clusters, hosts, virtual machines, and so on, but does not apply to the content libraries that you see and operate with in this vCenter Server instance. To assign a permission on a content library, an Administrator must grant the permission to the user as a global permission. Global permissions support assigning privileges across solutions from a global root object.

• Development pool - Low Share value with 10 virtual machines
Given this configuration, what is the expected performance for each group of virtual machines during contention?

• A. Virtual machines in the Production pool will perform two times as well as those in the Infrastructure pool.
• B. Virtual machines in the Infrastructure pool will perform four times as well as those in the Development pool.
• C. Virtual machines in all resource pools will perform equally.
• D. Virtual machines in the Development pool will perform two times as well as those in the Infrastructure pool.

Answer: C
