Failed AWS Cloud Practitioner? Here's Your Recovery Plan

Pro tip: Beta exams are the exception: a beta version may be taken only once, and a failed beta attempt must wait until the standard exam is generally available. Cancelling an appointment more than 24 hours in advance refunds the fee, and each appointment can be rescheduled twice, so moving a booking is usually cheaper than sitting unprepared.

• Studying at Solutions Architect depth because the AWS documentation is right there.
  The CLF-C02 exam guide names five out-of-scope tasks: coding, cloud architecture design, troubleshooting, implementation, and load and performance testing. If a study session drifts into subnet math or IAM policy JSON, you are burning time the exam will not reward.
• Treating the shared responsibility model as a single fixed diagram.
  The exam guide explicitly asks you to describe how responsibilities shift depending on the service, giving Amazon EC2, Amazon RDS, and AWS Lambda as examples. Learn the split three times, once per service model, not once in the abstract.
• Skipping Domain 4 because 12 percent sounds trivial.
  Twelve percent of 50 scored questions is about six questions, and Domain 4 content is the most memorisable on the exam. Support plan tiers, Trusted Advisor check availability, and the five Amazon EC2 purchasing options are pure recall, so they are the cheapest points on the paper.
• Leaving hard questions blank to come back to them and running out of time.
  AWS states that unanswered questions are scored as incorrect and there is no guessing penalty. Answer every question on first pass, flag it, and revisit. A flagged guess is worth strictly more than a blank.
• Confusing AWS CloudTrail, Amazon CloudWatch, and AWS Config.
  CloudTrail records who did what through the API. CloudWatch collects metrics, logs, and alarms about how resources perform. Config records resource configuration state over time and evaluates it against rules. The exam tests this triangle repeatedly under Domain 2.
• Learning security service names without their jobs.
  Amazon GuardDuty detects threats from log analysis, Amazon Inspector scans workloads for vulnerabilities, Amazon Macie discovers sensitive data in Amazon S3, AWS Security Hub aggregates findings, AWS Shield defends against DDoS, and AWS WAF filters web requests. Questions describe the job and ask for the service.
• Assuming multiple response questions have exactly two correct answers.
  The exam guide says multiple response questions have two or more correct responses out of five or more options. Read the instruction line on each question, because the number you must select is stated there.
• Booking with a name in the AWS Certification Account that does not match the ID.
  AWS instructs test administrators not to allow a candidate to test if the first and last names on the ID and the account are not identical. Account name changes take two business days, so check the match at least a week before the exam.
• Relying on a quoted pass rate to judge readiness.
  AWS does not publish pass rates for any certification exam. Judge readiness on the AWS Official Practice Exam and on whether you can explain, not just recognise, each domain topic.
• Booking OnVUE without running the system test on the actual machine.
  AWS states that if your computer does not pass the system test, or you are more than 15 minutes late, you cannot launch the exam and your fee is forfeited. Run the Pearson VUE system test on the same laptop and network you will use on the day.
