Free VMware 3V0-21.23 Practice Test Questions 2026

An architect is documenting the design for a new multi-site vSphere solution. The customer has informed the architect that the workloads hosted on the solution are managed by application teams, who must perform a number of steps to return the application to service following a failover of the workloads to the secondary site. These steps are defined as the Work Recovery Time (WRT). The customer has provided the architect with the following information about the workloads:

Critical workloads have a WRT of 12 hours
Production workloads have a WRT of 24 hours
Development workloads have a WRT of 24 hours
All workloads have an RPO of 4 hours
Critical workloads have an RTO of 1 hour
Production workloads have an RTO of 12 hours
Development workloads have an RTO of 24 hours
The customer has also confirmed that the Disaster Recovery solution will not begin the recovery of the development workloads until all critical and production workloads have been recovered at the secondary site.

What would the architect document as the maximum tolerable downtime (MTD) for each type of workload in the design?

A. The different processor architectures across both sites will remediate against a shared vSphere Lifecycle Manager baseline.

B. The different processor architectures will be located in the same cluster to support vSphere Lifecycle Manager image-based remediation.

C. The different processor architecture within a single site will remediate against a single vSphere Lifecycle Manager image.

D. The different processor architectures across both sites will remediate against a single vSphere Lifecycle Manager image.

An architect is reviewing the security and compliance requirements for a new application that will be hosted on a vSphere 8 environment.

The following information has been noted about the new application:

The application stores and processes confidential data
The supporting virtual infrastructure is shared with other departments
No other application stores or processes confidential data
The application virtual machines must be able to run on any ESXi host in the cluster
The storage layer is a iSCSI attached SAN
Data at Rest Encryption is in place for each presented LUN validated to FIPS 140-2
No budget is available for additional infrastructure components or software
Application data must not be accessible outside of the application's virtual machines
The architect has been tasked with providing a secure virtual machine design to host the application.

Which three design elements must the architect include to meet the requirements?
(Choose three.)

A. Virtual Machine Encryption

B. The vSphere Native Key Provider

C. A new encrypted iSCSI LUN

D. External Key Management Service (KMS) provider

E. A new local VMFS volume

F. VMware vSAN

An architect is documenting the logical design for a new vSphere solution. The following requirements have been provided to the architect by the customer for the design:

The solution must be deployed in two locations: DC1 and DC2
The solution must limit the impact radius of accidental changes by administrators
The solution must meet a recovery time objective (RTO) of four (4) hours and recovery point objective (RPO) of 24 hours
The solution must allow workloads to run in both DC1 and DC2 during normal operations
The solution must allow workloads to be moved bi-directionally between DC1 and DC2
The solution must use hyper-converged infrastructure for the virtual machine storage
The customer has also confirmed that the network connection between DC1 and DC2 has a 10 Gbps bandwidth with a maximum round trip latency of 4 ms.

The architect recommends the following design decision:

Use separate clusters in DC1 and DC2 to form a multi-region design

What should the architect include as justification for this design decision?

A. Sufficient capacity must be deployed in both DC1 and DC2 to support all running virtual machines.

B. Using separate clusters mitigates the risk of an accidental change at the cluster level in DC1 from impacting DC2.

C. Using separate clusters is the only configuration available that supports the RTO of four (4) hours.

D. The network connection between DC1 and DC2 does not support the use of stretched clusters.

What is an example of an availability design quality?

A. A vSphere cluster is configured to support an N + 1 level of redundancy.

B. A vSphere cluster is configured to support a maximum tolerated downtime of one hour.

C. A vSphere cluster is configured to stage patches on ESXi hosts before applying them.

D. A vSphere cluster is configured to use a dedicated network adapter for vMotion traffic.

An architect is designing the datastore configuration of a new vSphere-based solution. The following information was obtained during the initial meeting with the customer: There is currently 500 production and DMZ virtual machine workloads spread evenly across the primary and secondary site.

The profile of the workloads (per site) is as follows:

- DMZ:

-- 75 x Small: 1 vCPU, 2GB RAM, 200 GB disk

- Production:

-- 50 x Small: 1 vCPU, 2 GB RAM, 200 GB disk
-- 100 x Medium: 2 vCPU, 4 GB RAM, 200 GB disk
-- 25 x Large: 4 vCPU, 8 GB RAM, 500 GB disk

The average IO Profile per workload is 70/30 read/write.
The solution should cater to 10% storage growth in the first year.
The solution should cater to 15% virtual machine snapshot overhead.
The storage team has confirmed:

- A scalable external storage array has been deployed per site to support the storage requirements.
- The storage array will connect to all hosts using a dedicated Fibre Channel storage area network fabric.
- Usable storage capacity is available in 10 TB LUNs.
- As many LUNs as required can be provided.
- Every effort should be made to ensure the number of required LUNs is minimized.

The security team has stated that all DMZ and production workloads must remain logically isolated from each other.

Given the information provided, which three design decisions should the architect make to meet the requirements? (Choose three.)

A. Six 10TB VMFS datastores will be configured on each site for all production workloads.

B. Four 10TB VMFS datastores will be configured on each site for all production workloads.Four 10TB VMFS datastores will be configured on each site for all production workloads.

C. Each 10TB LUN will be configured as a VMFS datastore.

D. Two 10TB VMFS datastores will be configured on each site for all DMZ workloads.

E. Each 10TB LUN will be configured as an NFS datastore.

F. Seven 10TB VMFS datastores will be configured on each site for all workloads.
