Exam Day Tips and Strategies

Before the Exam

• Arrive at the testing center 15-30 minutes early, or prepare your remote testing environment at least an hour before
• Bring valid government-issued ID matching your registration name exactly
• Review case studies one final time—you can access them during the exam on a split screen
• Ensure you’re well-rested; avoid cramming the night before
• Eat a proper meal and stay hydrated before your exam

During the Exam

• Read each question carefully—identify key requirements and constraints
• Use the case study split-screen feature for context on relevant questions
• Eliminate obviously wrong answers first to improve your odds
• Flag difficult questions and return to them after completing easier ones
• Aim to reach case study questions with 45-50 minutes remaining
• Don’t spend more than 2-3 minutes on any single question
• When two answers seem equally correct, choose the one that follows GCP best practices and managed services

Technical Tips

• For security questions, default to least-privilege access and managed encryption
• When cost optimization is mentioned, consider sustained use discounts, committed use, and right-sizing
• For hybrid scenarios, evaluate Cloud Interconnect vs. VPN based on bandwidth and reliability requirements
• Trust managed services over self-managed solutions unless specific requirements dictate otherwise
• Remember that Cloud Spanner is ideal for global consistency, while regional solutions may be more cost-effective for local workloads

Common Mistakes to Avoid

Mistake 1: Neglecting Case Studies

Problem: Many candidates skip reviewing the official case studies before the exam, wasting valuable time reading them for the first time during the test.

Solution: Study all four case studies (Altostrat Media, Cymbal Retail, EHR Healthcare, KnightMotives Automotive) thoroughly before exam day. Create one-page summaries highlighting key requirements, constraints, and likely architectural solutions.

Mistake 2: Focusing Only on Theory

Problem: The exam tests practical application, not just theoretical knowledge. Candidates who only read documentation without hands-on practice struggle with scenario-based questions.

Solution: Complete at least 40-50 hands-on labs on Cloud Skills Boost. Build personal projects implementing multi-region deployments, hybrid networking, and CI/CD pipelines.

Mistake 3: Underestimating the Well-Architected Framework

Problem: The Google Cloud Well-Architected Framework is fundamental to the exam, yet many candidates treat it as supplementary material.

Solution: Study each pillar (operational excellence, security, reliability, performance optimization, cost optimization, sustainability) and understand how to apply them when evaluating architectural trade-offs.

Mistake 4: Poor Time Management

Problem: With 50-60 questions in 120 minutes, spending too long on difficult questions leaves insufficient time for easier ones.

Solution: Practice with timed exams. Flag difficult questions and return to them later. Aim for an average of 2 minutes per question, leaving buffer time for review.

Mistake 5: Ignoring Recent GCP Updates

Problem: The 2025 exam includes new topics like Vertex AI, Gemini integration, and AI Hypercomputer that weren’t in older study materials.

Solution: Always check the official exam guide for updates. Follow the Google Cloud Blog for new service announcements and ensure your study materials reflect current content.
