3V0-21.23 Free Practice Test

An architect is tasked with recommending a solution for a company that is running out of VLANs. Currently the company is running two separate data centers based on vSphere including an Enterprise Plus license. In the first data center, the problem was solved by using VMware NSX and overlay network. In the second data center, there is currently no VMware NSX implementation in place and no budget for additional licenses.
What should the architect recommend as a potential solution to provide support for additional VLANs?

1. A. Separate Distributed Virtual Switches (DVS)
2. B. Private VLANs (PVLAN)
3. C. Virtual Guest Tagging (VGT)
4. D. vSwitch VLAN Tagging (VST)

Correct Answer: A

An architect is designing a VMware software-defined data center (SDDC) solution based on the following customer requirements:
The solution must initially support 1,000 virtual machines
The solution must scale to support the concurrent running of up to 5,000 virtual machines
The production environment should be delivered across two data centers
The solution should have a maximum tolerable downtime (MTD) of four hours
The solution should have a monthly service availability target of 99.8%
Which two assumptions could the architect make based on the information from the customer to help size the solution? (Choose two.)

1. A. The number of vSphere hosts in a cluster
2. B. The average resource utilization of a virtual machine
3. C. The size (CPU/RAM/storage) of the average virtual machine
4. D. The guest operating system for each virtual machine
5. E. The size (CPU/RAM/storage) of the vSphere hosts

Correct Answer: AE

During a requirements gathering workshop, the customer provides the following requirement (REQ) and constraints (CON):
REQ01: The customer is looking for a way to limit database virtual machine (VM) placement to save on CPU licensing costs.
CON01: There is a single cluster with no budget to scale.
CON02: All virtual machines must run on the consolidated cluster.
Which two design decisions should the architect make to meet the customer requirement? (Choose two.)

1. A. The solution must use VM-VM anti-affinity rules
2. B. The solution must use vSphere DRS in manual mode
3. C. The solution must use a vRealize Orchestrator workflow for VM placement
4. D. The solution must use VM-Host affinity rules
5. E. The solution must use vSphere VM and host DRS groups

Correct Answer: DE

An architect is tasked with planning the design of a new vSphere environment. When commissioned, this environment will be used to migrate an existing set of virtual machines.
An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided.
In order for each virtual machine to be migrated, which two data sources with peak and average utilization data are required for sizing? (Choose two.)

1. A. %Ready
2. B. Disk Write latency
3. C. CPU
4. D. Ballooned memory
5. E. IOPS

Correct Answer: BE

An architect is considering placement of virtual machines within an existing VMware software-defined data center (SDDC).
During the discovery phase, the following information is documented:

Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)

1. A. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster One.
2. B. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster One.
3. C. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Two.
4. D. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two.
5. E. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Three.
