VMware Advanced Design VMware vSphere 7.x 3V0-21.21 Exam Dumps: Updated Questions & Answers (October 2025)

Question # 1

An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.

During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:

    The solution must initially support the concurrent running of 300 production and 600 development virtual machines.

    The production environment should be delivered across two geographically dispersed data centers. The development environment must be vSphere-based but does not have to be deployed on-premises.

    The two data centers are connected to each other through multiple diversely routed, high bandwidth and low latency links.

    The customer’s server hardware standard document states that all virtual infrastructure hosts must be based on blade architecture only.

    The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities, such as the monthly software patching and ad-hoc hardware break/fix.

    All virtual machine backups must be completed using the existing backup service. The recovery time objective (RTO) for the service is four hours.

    The recovery point objective (RPO) of the service is 24 hours.

Given the information from the customer, which two would be classified as assumptions within the design? (Choose two.)

A.

The backup service will store data in a secure facility

B.

The backup service has sufficient capacity for the new requirements

C.

The customer will update their hardware standard to support rack mount servers

D.

All virtual machines will be deployed with the same resource profile for production and development

E.

The clusters will have a minimum redundancy of N+1

Question # 2

Which two of the listed requirements would be classified as manageability non-functional requirements? (Choose two.)

A.

ESXi clusters must scale when compute resources are sustained above 70% for five business days

B.

vSphere Fault Tolerance must be supported to improve application uptime

C.

ESXi host updates must be installed within one week of release

D.

The vSphere environment must support administrator password rotation

E.

ESXi clusters must scale to 500 concurrent virtual machines

Question # 3

Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?

A.

A new subnet will be provisioned for vCenter HA services

B.

A vSphere cluster will consist of more than three nodes

C.

The deployed vCenter Server will be Tiny

D.

The vCenter HA network will support a latency of less than 50 ms

Question # 4

An architect is designing a new greenfield environment with 600 ESXi hosts in an automated fashion. The engineering department already has a PXE Boot server, TFTP server, and DHCP server set up with an NFS mount for their current Linux servers.

The architect must be able to demonstrate and meet a security requirement to have all infrastructure processes separated.

Which recommendation should the architect make for the ESXi host deployment?

A.

Request an isolated network segment to use and dedicate it to Auto Deploy functions

B.

Ask the business to expand the engineering environment to service the virtual environment as well

C.

Request a common shared network with flexible security measures to accommodate different auto deployment options

D.

Deploy each ESXi host individually and document it to satisfy security requirements

Question # 5

An architect is tasked with designing a new VMware software-defined data center (SDDC) solution for an online retail customer who has a primary and secondary data center as well as 10 distribution hubs.

The customer has provided the following business requirements to help inform the design:

    The solution must support the running of up to 1,000 concurrent virtual machines across the primary and secondary data center.

    The solution must support the running of up to 20 concurrent virtual machines in each distribution hub.

    The solution must support the separation of management and lines-of-business application virtual machines.

    All management components (including directory services, backup, automation, operations and logging) must be deployed to the primary data center.

    All virtual infrastructure components must have redundancy of N+1.

    All sites are connected to each other using a wide area network that has multiple diversely routed links.

    The solution should support a monthly uptime target of 99.9%.

    The recovery time objective (RTO) for the solution must be four hours.

    The recovery point objective (RPO) for the solution must be 24 hours.

Given the information from the customer, which assumption should the architect include in the design?

A.

All business application virtual machines can be deployed into a single cluster within the primary data center.

B.

Each distribution hub should be configured with a backup device.

C.

The wide area network has sufficient bandwidth to support centralized management.

D.

Each cluster will have a minimum of four hosts.

Question # 6

An architect is preparing a design for a company planning digital transformation. During the requirements gathering workshop, the following requirements (REQ) and constraints (CON) are identified:

    REQ01 The platform must host different types of workloads including applications that must be compliant with internal security standard.

    REQ02 The infrastructure must initially run 100 virtual machines.

    REQ03 Ten of the virtual machines must be compliant with internal security standard.

    REQ04 The internal security standard specifies logical network separation for in-scope applications.

    CON01 The customer has already purchased the licenses as part of another project.

    CON02 The customer has five physical servers that must be reused.

Additionally, based on resource requirements, four physical servers will be enough to run all workloads. Which recommendation should the architect make to meet requirements while minimizing project costs?

A.

Use Network I/O Control to ensure the internal security zone has higher share value

B.

Purchase additional servers and plan separate, isolated clusters for workloads that must be compliant with internal security

C.

Use a single cluster and ensure that different security zones are separated at least with dedicated VLANs and firewall

D.

Use a single cluster and configure DRS anti-affinity rules to ensure internal security compliant virtual machines cannot migrate between ESXi hosts.

Question # 7

An architect is designing a VMware solution for a customer to meet the following requirements:

    The solution must use investments in existing storage array that supports both block and file storage.

    The solution must support the ability to migrate workloads between hosts within a cluster.

    The solution must support resource management priorities.

    The solution must support the ability to connect virtual machines directly to LUNs.

    The solution should use existing 32G fabric infrastructure.

    There is no budget for additional physical hardware.

Which design decision should the architect make to meet these requirements?

A.

The ESXi hosts will leverage Fibre Channel (FC).

B.

The ESXi hosts will leverage iSCSI.

C.

The ESXi hosts will leverage Fibre Channel over Ethernet (FCoE).

D.

The ESXi hosts will leverage NFS.

Question # 8
