Hands-on Practice Priority
- Spend at least 60% of study time on hands-on labs - this certification heavily tests practical knowledge
- Complete all available VMware Hands-on Labs multiple times to build muscle memory
- Create your own test environment using VMware trial licenses if possible
- Practice onboarding at least 5-10 different VNF/CNF packages to understand variations
- Document every hands-on exercise with screenshots and notes for quick review
Master ETSI MANO Framework
- The ETSI NFV MANO architecture is foundational - understand how TCA implements it
- Create a detailed diagram showing MANO components and their VMware TCA equivalents
- Memorize the functions of NFV Orchestrator (NFVO), VNF Manager (VNFM), and VIM
- Understand reference points (Or-Vi, Or-Vnfm, Ve-Vnfm, Vi-Vnfm) and what they enable
- Study how TCA-CP and TCA-M map to ETSI MANO components
Focus on Lifecycle Management
- Understand the complete VNF/CNF lifecycle from onboarding through termination
- Memorize the sequence of operations for instantiate, scale, heal, and update workflows
- Know the difference between Day-0 (initial deployment), Day-1 (configuration), and Day-2 (ongoing operations)
- Practice troubleshooting failed lifecycle operations in labs
- Study rollback procedures and error handling mechanisms
TOSCA and Descriptor Files
- Learn TOSCA YAML syntax and common structures used in VNF descriptors
- Understand the relationship between NSD, VNFD, and deployment flavors
- Practice reading and interpreting TOSCA templates - exam may include code snippets
- Know common node types, capabilities, and requirements definitions
- Study validation errors and how to fix malformed descriptors
Service Chaining Concepts
- Understand how traffic flows through service function chains
- Learn about classifiers, service functions, and service function forwarders
- Practice designing multi-VNF services with proper chaining
- Know the difference between E-Line, E-LAN, and E-Tree connectivity models
- Study how network service descriptors define service chains
Monitoring and Troubleshooting
- Learn key log file locations and what to look for in each
- Understand common error codes and their meanings
- Practice using CLI commands for diagnostics and verification
- Study integration with vRealize Operations Manager for telco workloads
- Know how to interpret alarms and take corrective actions
- Familiarize yourself with API endpoints for troubleshooting
Exam Format Preparation
- The exam has 70 questions in 105 minutes - practice time management (90 seconds per question)
- Passing score is 300/500, meaning you need approximately 60% correct
- Questions may include multiple choice, multiple select, and drag-and-drop scenarios
- Scenario-based questions require understanding complete workflows, not just isolated facts
- Flag difficult questions and return to them - don't get stuck on any single question
- Read each question carefully - VMware exams often include subtle distinctions
Documentation Navigation
- Bookmark key sections of official documentation for quick reference during study
- Practice navigating the documentation quickly - understand the table of contents structure
- Create your own quick reference guide with page numbers for critical topics
- Pay special attention to 'Best Practices' and 'Troubleshooting' sections
- Review release notes to understand latest features and changes
Exam Day Tips
- 1Arrive 15 minutes early for online exams to complete system checks and avoid technical issues
- 2Read each question completely before looking at answers - VMware questions often have important details at the end
- 3Eliminate obviously wrong answers first in multiple-choice questions to improve odds
- 4For scenario-based questions, identify the goal first, then evaluate which answer achieves it correctly
- 5Watch for absolute words like 'always,' 'never,' 'only' - these are often indicators of incorrect answers
- 6Don't change answers unless you're certain - your first instinct is usually correct
- 7Use the flag feature liberally - mark questions you're unsure about and review them if time permits
- 8Manage your time: aim to complete 35 questions in the first 50 minutes, leaving time for review
- 9If you don't know an answer, make an educated guess - there's no penalty for wrong answers
- 10Stay calm and confident - associate-level certifications test practical knowledge you've practiced in labs
- 11For drag-and-drop questions, think through the complete workflow sequence before placing items
- 12Remember that some questions may have multiple correct technical approaches - choose the BEST practice according to VMware methodology
