Exam Details: What to Expect
Exam Format
Candidates should be fully prepared for an advanced-level exam that goes beyond basic vSphere configuration and into complex infrastructure design and optimization.
- Type: Advanced-level certification exam
- Duration: 135 minutes
- Question Format: Primarily scenario-based multiple-choice questions requiring deep technical knowledge.
- Passing Score: VMware does not officially disclose the required percentage, but successful candidates often score above 300 out of 500.
- Prerequisites: No strict formal requirements, but in-depth vSphere 8.x experience is crucial.
This exam is not about memorizing basic facts it demands an architectural mindset, with the ability to evaluate complex business and technical requirements to develop optimal vSphere designs.
Key Topics Covered
Success in this exam requires strong command over multiple domains. VMware focuses on real-world scenarios where candidates must design, optimize, and troubleshoot vSphere-based architectures.
Here are the main areas covered:
- Compute Design – Advanced strategies for CPU and memory allocation, ensuring optimal performance in enterprise environments.
- Storage Design – Selecting between vSAN, NFS, and VMFS while considering performance, redundancy, and scalability.
- Networking Design – Designing robust networking architectures, including vSphere Distributed Switches (vDS) and NSX-T for micro-segmentation and network security.
- Availability & Recovery – Implementing high-availability (HA) and distributed resource scheduling (DRS) strategies, along with backup and disaster recovery solutions.
- Security & Automation – Role-based access control (RBAC), encryption, and automation strategies with vRealize for efficiency and compliance.
What’s New in vSphere 8.x That You Must Know?
VMware vSphere 8.x introduces key improvements that make it a more powerful, scalable, and automated virtualization platform. Candidates taking this exam must understand these new capabilities:
- Distributed Services Engine – Enhances workload performance by offloading networking and security functions to DPUs (Data Processing Units).
- vSAN 8 Architecture – Delivers higher performance and resilience, with new storage policies for workload optimization.
- Tanzu Kubernetes Grid Integration – Makes Kubernetes deployment more streamlined, reducing operational complexity.
- vSphere Trust Authority – Strengthens security by managing cryptographic operations centrally, protecting workloads.
How to Prepare Without Wasting Time
Get Familiar with Official VMware Docs
VMware provides official documentation and whitepapers that serve as the best primary study resource. These documents offer detailed technical explanations of vSphere 8.x architecture, networking, storage, and security.
Hands-on Practice is Key
Experience matters. If you don’t have access to a live VMware environment, use VMware Hands-on Labs (HOLs) to gain real-world exposure. VMware’s virtual labs allow candidates to explore vSphere features without setting up their own infrastructure.
Use Practice Tests to Gauge Readiness
Taking mock tests is a great way to assess knowledge gaps and get comfortable with the exam format. VMware’s exams often include scenario-based questions, so understanding how real-world solutions apply to exam questions is essential.
Join VMware Study Groups
Online communities like VMware forums, LinkedIn groups, and Reddit communities are valuable resources. Engaging with professionals who have already passed the exam provides practical insights that may not be covered in official VMware materials.
Preparing for VMware 3V0-21.23 is a commitment, but with the right mix of study resources, hands-on practice, and community engagement, candidates can develop the expertise needed to excel in advanced VMware design.
