AWS Certified Machine Learning - Specialty Exam Prep Add-On (exam retired March 31, 2026)Domain 1 · Data Engineering

An ML team needs to land 10 GB/hour of clickstream events into S3 in near real time, partitioned by event date. They want the lowest operational overhead. Which combination best fits?

Confidence

Two habits before the first question

  • EVIDENCE-BACKEDAnswer from memory first, then check. It feels harder than rereading, and it works better. (Roediger and Karpicke, 2006 and others)
  • EVIDENCE-BACKEDSet the confidence slider before you check. Your rating on each question shows where you feel sure and are wrong. (Couchman et al., 2016)
Why this works

EVIDENCE-BACKED At least one peer-reviewed study or official source found the effect or states the fact. A study can be small.

Tested students kept more at two days and one week than students who restudied, and the result held in a randomized trial with medical residents at six months.

Per-question confidence predicted real exam performance far better than post-exam feelings.
