Simulate real exam conditions
For the most realistic DVA-C02 simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (130 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
What this DVA-C02 mock exam covers
This free DVA-C02 mock exam uses the same question distribution as the real AWS Certified Developer Associate DVA-C02 exam. Each session draws questions proportionally from all 4 blueprint domains published by Amazon Web Services, so the topic mix you see accurately reflects what you'll face on test day.
DVA-C02 Domain Distribution
Development with AWS Services
Security
Deployment
Troubleshooting and Optimization
Every question is written by certified engineers against the 2026 DVA-C02 exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Mock exam vs practice test: what's the difference?
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your DVA-C02 study plan.
Practice test — for learning
Use the DVA-C02 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the DVA-C02 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

Sample DVA-C02 mock exam questions

A developer has an AWS Lambda function that processes messages from an Amazon SQS queue. The function is configured with a batch size of 10, reserved concurrency of 5, and a timeout of 5 minutes. The SQS queue has a large backlog, and CloudWatch metrics show high throttling (Throttles) for the Lambda function. The function is idempotent and can process up to 100 messages in a single invocation. What is the MOST effective way to increase throughput without increasing the reserved concurrency?

A developer has an AWS Lambda function that needs to read objects from an S3 bucket in another account. The Lambda function's execution role includes an IAM policy that allows s3:GetObject on the bucket. The bucket owner has added a bucket policy that grants s3:GetObject to the Lambda execution role. However, the Lambda function receives Access Denied errors. The S3 bucket uses SSE-KMS for encryption. What is the most likely cause?

A developer is using AWS CodeDeploy with a blue/green deployment strategy to update an application running on Amazon ECS with the Fargate launch type. After the new (green) task set is created and traffic is shifted to it, users immediately report errors when trying to write data. The developer discovers that the green task set is connecting to a different database than the blue task set. The database endpoints are configured in the ECS task definition. What is the simplest way to prevent this issue in future deployments?

A developer deployed a new version of an AWS Lambda function that is part of a serverless application. The function uses an Amazon DynamoDB table as a data store. After deployment, the developer notices that the function's latency has increased significantly for some requests. CloudWatch traces show that the increase is due to DynamoDB throttle events. The function is configured with a reserved concurrency of 100 and the DynamoDB table has 5 read capacity units (RCUs) and 5 write capacity units (WCUs). What is the most effective way to reduce the throttling while maintaining application performance?

DVA-C02 exam-day strategy
Sitting the DVA-C02 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The DVA-C02 gives you 0.4 minutes per question. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most DVA-C02 distractors contain a subtle error — look for absolute language (always, never, only) as a red flag.
Amazon Web Services writes many DVA-C02 questions as realistic IT scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real DVA-C02 is a mental marathon. In the week before your exam, do at least two full 300-question sessions on separate days to build concentration stamina. If you cannot focus for 130 minutes in practice, you will struggle on exam day.

Scaled scoring
The DVA-C02 uses scaled scoring — your raw percentage correct is converted to a score out of 1000. Consistently scoring above 80% on mock exams puts you well above the 720 threshold, giving you a buffer for any unexpected question types on the real exam.
DVA-C02 mock exam — frequently asked questions
Is this DVA-C02 mock exam free?
Yes — all mock exam questions are completely free with no account required. Create a free Courseiva account to save your scores, see per-domain performance, and track your readiness over time. The platform is free forever, supported by advertising.
How does the DVA-C02 mock exam differ from the practice test?
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
What score should I aim for before booking my DVA-C02 exam?
Aim for consistent scores of 80% or above on full-length DVA-C02 mock exams before booking your test date. The official passing score of 720/1000 corresponds to roughly 72–75% correct answers, so an 80% buffer accounts for the difficulty variation and question styles on the real exam.
How many times should I do a full DVA-C02 mock exam?
Most candidates who pass DVA-C02 on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
Are these DVA-C02 mock questions the same as exam dumps?
No — all Courseiva questions are original, written by certified engineers against public Amazon Web Services exam blueprints. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your Amazon Web Services certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
