Module 15 study guide
Module 15 · Work through your exam, one topic at a time.
Module 15 is a multiple-choice examination organised around five domains: Fundamentals and Core Concepts (20%), Planning and Design (20%), Implementation and Configuration (25%), Operations, Monitoring, and Maintenance (20%), and Troubleshooting and Governance (15%). The weighting tells you where the marks sit: implementation and configuration is the single largest block, and the two 20% planning and operations domains together account for a further 40%, so an approach that only drills definitions and terminology will leave a large share of the paper untested. Candidates best suited to this exam are practitioners who already work with the subject matter day to day and need a structured way to confirm and fill gaps in their knowledge, rather than complete beginners looking for a first introduction. Preparation should be built around the published content outline: work through each domain, map your existing experience against the objectives, and spend the most time on the objectives you cannot yet explain or demonstrate without notes. The Module 15 study guide has 5 sections and about 2,042 words.
01Fundamentals and Core Concepts
This domain tests whether you can reason about a solution as a lifecycle system rather than a feature list. Questions target boundaries, requirement quality, constraints, trade-offs, and the feedback loops that keep a system fit for purpose.
400 words, about 2 min02Planning and Design
This domain tests how you turn validated requirements into an architecture and delivery plan that survive real constraints. Questions target architecture decisions, capacity, failure domains, recovery objectives, and review evidence.
424 words, about 2 min03Implementation and Configuration
This domain tests whether you can move from an approved design to a repeatable, auditable running state. Expect questions on infrastructure as code, environments, secrets, deployment strategy, and configuration control.
392 words, about 2 min04Operations, Monitoring, and Maintenance
This domain tests whether you can keep a live service healthy and prove it. Expect SLIs and SLOs, alert design, on-call practice, patching, backup restore, and maintenance planning.
419 words, about 2 min05Troubleshooting and Governance
This domain tests structured diagnosis under pressure and the controls that keep decisions defensible. Expect incident triage, change correlation, postmortem quality, and governance evidence.
