3V0-21.21 Online Practice Questions and Answers

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:

Cluster One Six ESXi hosts vSphere HA with host failures cluster tolerates = 1 Proactive HA is enabled and set to automated Fully Automated vSphere DRS Transparent Page Sharing (TPS) is enabled

Cluster Two Eight ESXi hosts vSphere HA with host failures cluster tolerates = 1 Proactive HA is disabled Partially Automated vSphere DRS Transparent Page Sharing (TPS) is disabled Cluster Three Three ESXi hosts vSphere HA with admission control is disabled Proactive HA is not supported Transparent Page Sharing (TPS) is disabled

Virtual Machine Resource Profile 1 Memory sharing techniques should not be used Virtual machines should be automatically restarted in the event of host failure if resources are available Automated initial virtual machine placement

Virtual Machine Resource Profile 2 Memory sharing techniques should not be used Virtual machines should be automatically restarted in the event of host failure regardless of available resources Automated initial virtual machine placement

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

A. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster One.

B. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster One.

C. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Two.

D. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two.

E. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Three.

Following a recent acquisition, an architect needs to merge IT assets into its current data center. The

combined vSphere environment will need to run the newly acquired company's virtual machines.

Network integration work has already been completed and the current environment has capacity to host all

virtual machines. The Operations team needs to identify which virtual machines belong to the acquired

company and report on their usage.

How should the architect merge the company's assets and virtual machines?

A. Leave the newly acquired company's assets in its current place

B. Lift and shift the acquired assets into the data center

C. Migrate the acquired company's virtual machines into the existing vSphere environment

D. Migrate and apply vSphere tags to the acquired company's virtual machines

A customer has a database cluster with 40/60 read/write ratio and a high IOPs requirement with no contention on an all-flash vSAN cluster.

Which two storage settings should be configured for best performance? (Choose two.)

A. IOPs limits enabled

B. RAID 1

C. Deduplication and Compression disabled

D. RAID 5/6

E. Deduplication and Compression enabled

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?

A. Separate Distributed Virtual Switches (DVS)

B. Private VLANs (PVLAN)

C. Virtual Guest Tagging (VGT)

D. vSwitch VLAN Tagging (VST)

A new vSphere platform is being created. The platform will host virtual machines that will run management services and line-of-business applications.

What should the architect consider when designing the number and type of clusters required?

A. Maximum tolerable downtime

B. Predicted platform growth

C. Auditing requirements for the virtual machines

D. The level of isolation required between virtual machine classifications

An architect is planning the physical server configuration for a vSAN-based infrastructure.

Which operations mode should a RAID controller support to minimize potential server downtime during physical disk failures?

A. RAID controller with Passthru mode

B. RAID controller with RAID 5 mode

C. RAID controller with RAID 10 mode

D. RAID controller with RAID 6 mode

The architect for a large enterprise is tasked with reviewing a proposed design created by a service partner.

Which design elements are expected to be detailed within the physical design section of the documentation?

A. A design diagram illustrating the configuration and specific attributes, such as IP addresses

B. A list of requirements, constraints, and risks

C. A solution architecture diagram with the components and data flow

D. An entity relationship diagram describing upstream and downstream dependencies for specific service components

Which of the listed requirements would be classified as a recoverability non-functional requirement?

A. The platform must be integrated with existing change control policies.

B. The platform must be able to support a maximum tolerable downtime (MTD) of 30 minutes.

C. Maintenance windows must be scheduled to take place monthly during an established overnight period.

D. The platform must be available 24 hours a day, 7 days a week with the exception of scheduled downtime.

An architect is tasked with designing a new VMware software-defined data center (SDDC) using VMware vSAN. The architect uses a storage assessment tool to determine the storage requirements for the new vSAN cluster. The new SDDC is going to be deployed into the existing data center and must be connected to a shared core network switch.

The architect decides to use vSAN ReadyNodes with the following configuration:

Two disk groups with:

-Write Intensive NVMe 800 GB drive for cache

-Four 3.84 TB Mixed Use NVMe for capacity Four 10 GbE ports

Which element represents a risk that should be included in this design?

A. The number of 10 GbE capable ports in the vSAN ReadyNode

B. The use of vSAN ReadyNodes

C. The existing network is 10 GbE capable

D. The use of NVMe drives for cache and capacity

A VMware Service Provider is tasked with delivering a solution for continuous availability for a subset of Tier 1 virtual machines (VMs) and vApps running in their vSAN environment. The VMs make up a mission-critical application and there can be no data loss in the event of an outage at their primary data center. In the event of a regional outage, they have established a 10-minute recovery point objective (RPO). Failover/ failback to the third site must be automated.

They have the following in place:

Two local data centers (primary and secondary) connected with 100 Gb dedicated fiber

-2ms round-trip time (RTT) latency between the sites A third data center located on another power grid

-70ms latency between the primary and secondary data centers Matching storage arrays at all locations Which two solutions could be used to meet the requirements? (Choose two.)

A. Site Recovery Manager

B. Snapshots

C. vSAN Metro Cluster

D. vSphere Data Protection

E. vStorage APIs for Array Integration (VAAI)
