VMware 5V0-21.21: What You Need to Ask First
Recommended: VCP-DCV certification, 1–2 years hands-on experience with vSphere and vSAN; no mandatory prerequisite These requirements are set by VMware and can change, so confirm the current rules on the official exam page: https://www.broadcom.com/support/education/vmware/certification/5v0-21-21 before registering for the VMware HCI Master Specialist exam.
Delivery is instant: your 5V0-21.21 product is emailed within one minute of payment — download the attachment and start. If nothing arrives within 2 hours, check spam and contact support for an immediate resend. On failure: sit the corresponding 5V0-21.21 exam within 60 days of purchase, submit a scanned enrollment slip and the official Score Report PDF within 2 days after the exam, and the refund completes within 7 days. The policy covers the corresponding exam only; attempts within 3 days of purchase, exams never actually taken, free materials, and expired orders are excluded, and the candidate name must match the payer name. If you prefer, exchange your product for two free exam products of equal value and keep the update service on the original.
Registration runs through VMware's official channels:
The exam is delivered via Proctored online or onsite at Pearson VUE test centers, so pick the option that fits you when booking.
The VMware HCI Master Specialist exam contains 50–55 questions within 100 minutes. The ratio is the real challenge — content alone does not finish the exam, pacing does. Run full timed sessions in the Lead2PassExam test engine until finishing early feels normal on the real 5V0-21.21 exam.
These are the vendor's recommended training options:
Training builds the theory; the 68 practice questions for the 5V0-21.21 exam from Lead2PassExam test it under real exam conditions.
VMware spreads the VMware HCI Master Specialist syllabus over 5 areas, led by Installation, Configuration, and Setup (20%), Troubleshooting and Recovery (15%), Planning and Designing (25%). Study proportionally to those shares — the complete outline is in the section above this page.
The 5V0-21.21 exam is VMware's official certification test — passing it earns the VMware Certified Master Specialist - HCI 2021 credential at the Master Specialist / Advanced level. It measures practical IT ability objectively, which is why employers treat the VMware HCI Master Specialist certificate as a reliable signal — and why candidate numbers keep growing. It also relates to VMware Certified Professional - Data Center Virtualization (VCP-DCV), VMware vSAN Specialist, extending its value further.
Each VMware HCI Master Specialist attempt costs $250 USD, with 300 (scaled 100–500) as the pass mark. A retake charges the full fee again, so the smart move is arriving overprepared. Practice with Lead2PassExam until your timed mock scores clear 300 (scaled 100–500) comfortably, then book the 5V0-21.21 exam once.

After purchase, 365 days of free updates are included; once the year ends, extend the update service at a 50% discount from your member zone.

Correct Answer: A 🗳️
An administrator would like to upgrade ten identically configured 2-node vSAN clusters from vSAN 6.7 U3 to vSAN 7.0 U1. Currently, each 2-node vSAN cluster is using a dedicated vSAN witness host appliance. As a result of the upgrade, the administrator would like to leverage the vSAN shared witness feature to reduce the resources being consumed.
In preparation for the first vSAN cluster upgrade, the administrator has completed the following tasks:
1. Upgraded vCenter Server to vCenter Server 7.0 U1.
2. vSphere High Availability (HA) has been disabled on the vSAN Cluster.
3. Upgraded the vSAN witness host appliance to vSphere 7.0 U1.
4. Upgraded both vSAN data nodes to vSphere 7.0 U1.
The key requirement is to ensure that backwards compatibility to the existing version of vSAN is maintained during the upgrade process.
Which three additional steps should the administrator complete to ensure that subsequent clusters can share the same vSAN Witness? (Choose three.)
- A. Upgrade the vSAN On-Disk Format (ODF) to version 12.
- B. Upgrade the vSAN On-Disk Format (ODF) to version 13.
- C. Deploy a new vSAN 7.0 U1 witness host appliance to act as a shared witness.
- D. Update the vSAN cluster to use the new vSAN witness host appliance.
- E. Manually update the vSAN Witness with a vSAN 7 license key.
