AWS Certified Machine Learning Engineer – Associate (MLA-C02) Practice Tests

Validates skills in preparing data, building and tuning models, and deploying and securing machine learning workloads on AWS.

MLA-C02 questions are scenario-based multiple-choice and multiple-response items on SageMaker AI, Bedrock and ML pipelines, and the beta runs 85 questions in 170 minutes. We compared the main options on official coverage, exam-like difficulty and price.

Most people should start with AWS's free question set, add the official pretest, then use a bank written for MLA-C02. General availability is 14 January 2027, and English MLA-C01 ended on 28 September 2026.

Official Practice Question Set (MLA-C02)

20 AWS-written questions aligned to the MLA-C02 guide, with feedback on each answer choice and links to study resources. A retake reshuffles the same 20 questions.

Great fit if you want a free first look at MLA-C02 question style and the new generative AI topics.

Poor fit if you need a full-length rehearsal; take the Official Pretest.

Official full-length test

Official Pretest (MLA-C02)

AWS's full-length test with exam-style scoring and feedback on every answer choice. It lists 65 questions in 130 minutes, shorter than the 85-question, 170-minute beta exam.

Great fit if you want an AWS-written timed test, and also want the subscription's MLA-C02 domain practice courses.

Poor fit if you want a large pool of fresh questions or beta-length runs; add Maarek's exams.

Exam-like difficulty

Practice Exams: AWS Machine Learning Engineer Associate Cert

Three full-length 65-question tests, updated in September 2026 for MLA-C02, with detailed explanations. A 2026 passer found the MLA-C01 version as hard as the real exam, sometimes harder.

Great fit if you want exam-level difficulty and a way to practise multi-select questions.

Poor fit if you want beta-length runs; each test has 65 questions, not 85.

Cheap extra practice

AWS Certified Machine Learning Engineer Associate Practice Exams MLA-C02

Timed, review, section and randomized modes with explanations, reference links and flashcards. The page is labelled MLA-C02 but still carries MLA-C01 details, and MLA-C01 passers split on its quality.

Great fit if you want a cheap extra bank with explanations linked to AWS documentation.

Poor fit if you need heavy generative AI and agent practice; Tutorials Dojo publishes no question count, so lean on the official questions and Maarek.

What to look for in a AWS Certified Machine Learning Engineer – Associate practice test

  • Written for MLA-C02, not relabelled MLA-C01. MLA-C02 keeps four domains weighted 28%, 24%, 24% and 24% and adds foundation models, RAG, embeddings, Bedrock Guardrails, agents and LLM evaluation, while dropping SageMaker Neo edge optimization and bring-your-own-container. A bank built for C01 under-tests half of the new outline.
  • Question types as AWS lists them. AWS's exam guide lists multiple choice and multiple response only. Some banks advertise matching, ordering or case-study items; do not pick a bank for formats the guide does not list.
  • Multi-select practice. A multiple-response question earns credit only if you pick every correct option. A 2026 passer said select-two and select-three questions were the hardest part of Maarek's exams.
  • Explanations that name the service and the setting. Passers say the exam is about choosing the right SageMaker AI or Bedrock feature for a scenario, and that real distractors are closer than in mock exams. Prefer explanations that say why each wrong option fails.
  • Official wording first. The Practice Question Set and Pretest are the only AWS-written questions, and the only ones certain to follow the MLA-C02 guide. Use third-party banks for volume once you know the style.
  • Skip sites selling "real exam questions." Sites promising actual MLA-C02 questions or a guaranteed pass are selling leaked or copied items. AWS's certification agreement bans using leaked exam content and lets AWS revoke some or all of your AWS certifications. A real practice test explains why each answer is right; a dump only lists answers.

How to use AWS Certified Machine Learning Engineer – Associate practice tests

  • Start with the free 20 questions and the exam guide. Take AWS's question set cold, then mark which task statements you missed, especially the new RAG, Bedrock and agent tasks.
  • Review every explanation and cross-check misses. MLA-C01 passers say each bank had gaps or debatable answers. Check a missed question against AWS documentation or a second resource before you trust the key.
  • Link scenario keywords to services and settings. Passers recommend noting which words in a scenario point to a SageMaker AI feature, a Bedrock capability or a security setting, because the real answer options are harder to rule out than mock options.
  • Cover the new topics deliberately. A beta passer says the exam leans on generative AI and agents next to classic ML, with LLM evaluation easy to underestimate. If your bank has few such questions, add the MLA-C02 domain practice courses in Skill Builder.
  • Plan several weeks. Detailed pass reports describe a month or more of steady study even with a data or AWS background. Take full timed runs near the end rather than early.

AWS Certified Machine Learning Engineer – Associate practice test FAQ

Are there free MLA-C02 practice tests?

Yes. AWS's Official Practice Question Set has 20 questions with a free Skill Builder account. Tutorials Dojo's free sampler is still MLA-C01, so it is older than the current outline.

Is MLA-C02 harder than MLA-C01?

It is broader: AWS added generative AI, RAG and agent tasks to the classic ML engineering ones. One beta passer called it fair for people who build with SageMaker AI and Bedrock, while another failed and found the questions all over the place.

How many questions are on the MLA-C02 exam?

The beta has 85 questions in 170 minutes and costs $75, in English only. AWS's exam guide lists 65 questions, 50 scored and 15 unscored, and general availability is 14 January 2027.

Can I still use MLA-C01 practice tests?

Partly. Most C01 topics still appear, but C01 banks lack the generative AI, RAG and agent tasks added in C02. Use them for the classic ML half and cover the rest with AWS's official questions.
