Hands-On Practice is Critical
- Create an OCI Free Tier account immediately and practice every networking concept
- Build at least 5 different VCN architectures (hub-and-spoke, transit, multi-tier)
- Configure all three gateway types (Internet, NAT, Service) and understand their traffic flows
- Practice troubleshooting connectivity issues using VCN Flow Logs and Network Path Analyzer
- Set up and tear down resources repeatedly to memorize the configuration steps
Master the Documentation
- The official OCI documentation is your primary study resource - read it thoroughly
- Bookmark key documentation pages for quick reference during study sessions
- Pay special attention to 'Best Practices' and 'Limitations' sections in each service
- Study the architecture diagrams in the documentation - exam questions often reference similar scenarios
- Use the documentation search feature to explore related topics when studying a concept
Focus on Comparison and Selection
- Understand when to use Security Lists vs Network Security Groups (NSGs are more flexible)
- Know the differences between Network Load Balancer and Load Balancer (Application)
- Master FastConnect vs Site-to-Site VPN selection criteria and use cases
- Learn when to use Local VCN Peering vs Remote VCN Peering vs DRG
- Understand public vs private subnet use cases and routing differences
Understand Routing Deeply
- Route tables are fundamental to OCI networking - practice complex routing scenarios
- Understand how DRG route tables work with VCN attachments and IPSec connections
- Master the order of route evaluation and longest prefix match concepts
- Practice designing transit routing architectures with multiple VCNs
- Know how to troubleshoot routing issues using route table analysis
Study Real-World Architectures
- Review reference architectures in the OCI Architecture Center
- Understand enterprise patterns: hub-and-spoke, DMZ design, multi-tier applications
- Study hybrid connectivity patterns for connecting on-premises data centers
- Learn disaster recovery and high availability networking designs
- Practice drawing network diagrams for different business requirements
Memorize Key Limits and Quotas
- Know the default VCN limits (maximum VCNs per tenancy, subnets per VCN, etc.)
- Understand CIDR block restrictions and valid sizes for VCNs and subnets
- Memorize load balancer bandwidth limits and connection limits
- Learn FastConnect bandwidth options and regional availability
- Know security rule limits for Security Lists and NSGs
Practice Exam Strategy
- You need 68% to pass (approximately 38 correct out of 55 questions)
- Time management: 90 minutes for 55 questions gives you about 98 seconds per question
- Read questions carefully - OCI exams often test subtle differences between services
- Eliminate obviously wrong answers first to improve your odds
- Flag difficult questions and return to them after completing easier ones
- For scenario-based questions, identify the key requirement first (security, cost, performance)
Use Oracle LiveLabs Extensively
- Complete at least 10 networking-focused LiveLabs workshops before the exam
- LiveLabs provide pre-configured environments - no setup time wasted
- Follow the workshops exactly first, then try to recreate them from memory
- Pay attention to the CLI commands shown in workshops - understand what each parameter does
- Use LiveLabs to practice scenarios you can't easily create in Free Tier
Exam Day Tips
- 1Arrive at the test center 15-30 minutes early or test your online proctoring setup well in advance
- 2Bring two forms of ID if taking the exam at a test center
- 3Read each question completely before looking at answers - don't assume you know what's being asked
- 4Watch for absolute words like 'always', 'never', 'only' - they often indicate incorrect answers
- 5For design questions, consider cost, security, performance, and availability - not just functionality
- 6Use the mark/flag feature to note questions you want to review - don't spend too long on any single question
- 7Trust your hands-on experience - if a configuration 'feels wrong', it probably is
- 8Remember that OCI terminology is specific - 'Security List' is different from 'Network Security Group'
- 9If you're unsure between two answers, think about Oracle's recommended best practices
- 10Stay calm during the exam - 90 minutes is sufficient time if you've prepared well
- 11Review all flagged questions if time permits before submitting
- 12Don't change answers unless you're confident - your first instinct is often correct
