Understand the certification
Certification Overview
VMware 3V0-21.21 (Advanced Design VMware vSphere 7.x) is the VCAP-DCV Design 2021 exam. It checks whether you can turn business requirements into a complete vSphere 7.x architecture design. The focus is on requirements analysis, conceptual design, logical design, and physical design.
Exam Sections
- Architecture and Technologies: the AMPRS design framework and how to apply it
- VMware Products and Solutions: vSphere 7.x, vSAN, NSX, and vCenter high availability
- Planning and Designing: functional and non-functional requirements, conceptual design, logical design, and physical architecture
- Installing, Configuring, and Setup: design decisions for component deployment and configuration
- Performance Tuning, Optimization, and Upgrades: upgrade paths and performance choices
- Troubleshooting and Repairing: design-level troubleshooting considerations
- Administrative and Operational Tasks: operational design choices
Who Is This For
This certification is aimed at senior engineers and architects with a valid VCP-DCV and several years of vSphere design experience.

Before you register
How difficult is the VMware 3V0-21.21 vSphere 7.x Advanced Design exam?
This is a VCAP-DCV Design (VMware Certified Advanced Professional) level exam, significantly more difficult than VCP exams. The exam is 90 minutes long with 65 questions, requiring a 70% passing score. It focuses on advanced architecture design skills, requiring you to design complete vSphere solutions based on business requirements.
What is the difference between VCAP-DCV Design and VCP-DCV?
VCP-DCV tests knowledge of vSphere installation, configuration, and management operations, while VCAP-DCV Design tests the ability to create architecture designs based on business requirements. VCAP requires you to analyze requirements, evaluate constraints, and design logical and physical architectures. It is a certification for senior architects.
What topics does the vSphere 7.x Advanced Design exam cover?
Key exam topics include: requirements analysis and conceptual design, vSphere compute (clusters, resource pools, DRS/HA) design, storage architecture design (vSAN, VMFS, NFS), network architecture design (VDS, NSX integration), management and monitoring design, and business continuity and disaster recovery solution design.
What prerequisites are needed for the VCAP-DCV Design certification?
You must first hold a valid VCP-DCV certification. We recommend 3-5 years of vSphere design and deployment experience, with familiarity in enterprise infrastructure design methodology. Knowledge of TOGAF or similar architecture frameworks for requirements gathering and design documentation is helpful.
How can I effectively prepare for the vSphere 7.x Advanced Design exam?
We recommend systematically studying the official VMware vSphere: Design course, focusing on developing architecture design thinking. Practice capacity planning, high-availability design, and disaster recovery solution design starting from business requirements. Use our practice questions for review, paying attention to constraints and design trade-offs in each question.
