3V0-21.21 Exam FAQs for 2026 Candidates
Which certification does the 3V0-21.21 exam lead to?
The 3V0-21.21 exam is the official VMware exam behind the VCAP-DCV Design 2021 certification, validating the skills measured by the VMware Advanced Design VMware vSphere 7.x credential. It sits at the Advanced / Expert (VCAP-DCV Design) level of the VMware certification program. It also connects to VCAP-DCV Design, so the knowledge you build here carries over to those tracks as well.
How many questions are on the 3V0-21.21 exam, and how much time do I get?
The 3V0-21.21 exam contains 60 questions to be completed within 150 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.
What score do I need to pass the 3V0-21.21 exam, and what does it cost?
The passing score for the 3V0-21.21 exam is 300 (scaled), and the official registration fee is USD $250 (approx official retail). Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 90 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.
Are there any prerequisites for the 3V0-21.21 exam?
VMware Certified Professional – Data Center Virtualization (VCP-DCV) or equivalent experience recommended Requirements can change when VMware revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
Can I try the 3V0-21.21 practice questions before I buy?
Yes. Getcertkey provides a free 3V0-21.21 PDF demo so you can review the question style and answer quality before purchasing. Every purchase also includes 365 days of free updates — if VMware revises the exam during that period, the updated material reaches you at no cost. Once the free-update year ends, you can extend your update service at a 50% discount.

VMware Advanced Design VMware vSphere 7.x Sample Questions:
Question 1
An architect is designing a new vSphere platform to meet a list of requirements from the security team.
Which two requirements would be classified as non-functional requirements? (Choose two.)
A. Migration of virtual machines between hosts must be encrypted
B. Data integrity must be ensured
C. A common content library must be maintained across all data centers
D. Log information must be verbose to support incident resolution
E. Critical events generated within the platform must be logged to an external Syslog service
Question 2
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. Virtual Guest Tagging (VGT)
C. Private VLANs (PVLAN)
D. vSwitch VLAN Tagging (VST)
Question 3
A new real-time financial service application is being developed by the engineering team at a financial firm and will be released as a public Software-as-a-Service (SaaS) offering. The solutions architect has designed and deployed a new vSphere environment and the supporting network infrastructure for hosting all public services. ESXi hosts are configured to use Precision Time Proalhazi@1tocol (PTP) and a local stratum-1 network time server.
Application provisioning and scaling will be managed by VMware vRealize Automation and can be run on Microsoft Windows or multiple distributions of Linux.
Which three recommendations should the architect include in the design to ensure that the service maintain timekeeping within an accuracy of one second? (Choose three.)
A. Use a Linux distribution as the guest operating system.
B. Configure the chrony time-sync agent on each virtual machine guest operating system.
C. Set the virtual hardware device to use Host System Time (NTP) for each virtual machine running the application.
D. Add a precision clock virtual device to each virtual machine running the application.
E. Add a virtual watchdog timer (VWDT) device to each virtual machine running the application.
F. Use Microsoft Windows Server as the guest operating system.
Question 4
An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.
The platform has recently commissioned new hosts to update the development cluster.
The development cluster host configuration is:
4 ESXi hosts with 2 sockets × 16 cores
512 GB RAM divided evenly between sockets
There is no resource contention
The benchmarking cluster host configuration is:
8 ESXi hosts with 2 sockets × 8 cores
256 GB RAM divided evenly between sockets
There is no resource contention
The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.
What is a possible reason for the difference in performance test results between the development and benchmarking clusters?
A. The development cluster has more available RAM per host
B. The development cluster can support a lower %Ready time per vCPU
C. The database tier breaches a single NUMA node boundary for the development cluster
D. The database tier breaches a single NUMA node boundary for the benchmarking cluster
Question 5
An architect is designing a new backup solution for a vSphere platform that has been recently upgraded to vSphere 7.
The architect wants the backup solution to perform the following:
Full virtual machine image backup and restore
Incremental virtual machine image backup and restore
File level backup and restore within both Windows and Linux virtual machines LAN-free backup Which functional requirement should the architect include in the design of the new backup solution?
A. The backup solution must leverage virtual machine snapshots.
B. The backup solution must leverage VMware vSphere Storage APIs - Data Protection.
C. The backup solution must leverage the VMware Consolidated Backup (VCB) framework.
D. The backup solution must leverage VMware vStorage APIs for Data Protection (VADP).
