Common Mistakes to Avoid
Candidates usually commit common mistakes during DEA-C01 preparation. Candidates are required to understand AWS service selection, along with memorising concepts. You should not ignore lower- weight exam domains, as it can be asked in exams.
Always remember to study from updated AWS features, otherwise you will not be well prepared for your exam.
You should not skip real practical practice or training, as scenario based questions are asked in examination. Confusing Kinesis Data Streams with Amazon Data Firehouse, mixing IAM permissions with Lake Formation controls, overlooking cost optimization are some of the common mistakes done by candidates.
Exam Day Tips
- If the question gives a scenario and is long, read the last sentence and try to determine the key requirement.
- Consider using the words "least operational effort," "lowest cost," or "near-real-time" to help you determine service selection.
- Remove the word which is technically feasible but operationally less efficient.
- Identify hard questions to review and respond to questions as if they were correct (no penalty for guessing, AWS will only penalize for not answering).
- Use the last 10-15 minutes to check the answers.
- Before taking an online exam, ensure that the system, identity, and workspace requirements are met, as well as the proctoring requirements.
