1.1 CDS Exam Structure, Format & Certification Strategy

1.1 CDS Exam Structure, Format & Certification Strategy

Quick Summary: The ITIL 4 Specialist: Create, Deliver and Support (CDS) exam is a 40-question, 90-minute closed-book examination assessing your ability to integrate value streams, modern technologies, and operational practices. Passing requires 28 correct answers (70%). The exam exclusively targets Bloom's Levels 2 (Understanding) and 3 (Applying), demanding that you evaluate realistic organizational scenarios rather than recite definitions.

The ITIL 4 Specialist: Create, Deliver and Support (CDS) credential is a core specialist module within the ITIL 4 Managing Professional (MP) stream. While ITIL 4 Foundation introduces the conceptual scaffolding of the Service Value System (SVS), CDS explores the operational engine room of service management: how digital services are practically created, transitioned, operated, and continually improved.

Passing CDS requires an architectural mindset that views work as an end-to-end value stream, recognizes how practices supply capabilities across activities, and applies the four dimensions of service management to solve complex operational challenges.

Official PeopleCert Exam Specifications

The CDS examination is administered globally by PeopleCert under standardized testing criteria:

Mandatory Training Prerequisite

A strict PeopleCert rule is that passing the exam alone does not confer the credential. Two conditions must both be satisfied.

First, you must already hold an accepted prior certification. PeopleCert currently accepts any ITIL v3 certification, ITIL 4 Foundation, or the ITIL 4 Managing Professional certificate. Note that the old ITIL 4 Managing Professional Transition module was withdrawn on 30 September 2022 and is no longer an available route; candidates holding only ITIL v3 credits who want the full ITIL 4 scheme now start at ITIL 4 Foundation.

Second, you must complete an accredited training course through an Accredited Training Organization (ATO) or an official ITIL eLearning package. Independent exam takers will have their formal certificate and digital badge withheld until accredited course attendance records are validated.

The Three CDS Question Types

All 40 questions are multiple choice with four answer options, and there is no negative marking — never leave a question blank. However, the official syllabus defines three distinct question constructions, and candidates who expect only one of them lose marks to careless reading:

Exam mechanic: because list questions pair statements, confidently eliminating a single false statement removes two of the four answer options immediately.

Certification Timing: The 2027 Sunset

CDS is stable but time-boxed. PeopleCert states that the current plan is to sunset all ITIL 4 modules on 31 December 2027 as ITIL (Version 5) is introduced in phases. Three practical consequences follow:

• The CDS exam specification itself is unchanged — still 40 questions, 90 minutes, 70% to pass. Nothing in this guide is affected by the Version 5 rollout.
• If you intend to earn ITIL 4 Managing Professional, you must complete all four MP modules (CDS, DSV, HVIT, DPI) before the sunset date; leaving CDS until late 2027 leaves no room for a resit.
• ITIL 4 qualifications remain recognized as prerequisites on the Version 5 pathway, so passing CDS is not wasted effort. Holders progress through dedicated Bridge or Managing Professional Transition routes rather than restarting at Foundation.

Cognitive Depth: Bloom's Taxonomy Levels 2 and 3

The ITIL 4 Foundation exam features numerous Bloom's Level 1 questions testing raw definition recall. In contrast, the CDS examination completely eliminates Level 1 questions. The 40 questions are split exclusively between Bloom's Level 2 and Level 3:

• Bloom's Level 2 (Understanding - ~35% to 40%): Evaluates your ability to explain concepts, compare operating models, and contrast architectures. Examples include contrasting swarming models with tiered escalation or explaining why value stream mapping isolates wait time from process time.
• Bloom's Level 3 (Applying - ~60% to 65%): Evaluates your ability to apply ITIL concepts, techniques, and practices to concrete operational scenarios. Questions present mini case studies—such as a team experiencing deployment friction or a service desk overwhelmed by access requests—and require you to identify the optimal intervention.

Syllabus Weighting Across CDS Domains

The official syllabus divides content across three primary domains:

1. Plan and Build the Service Value Stream (~37.5% / ~15 Questions): Organizational structures, team culture, workforce planning, information models, collaboration tooling, modern engineering automation (RPA, AI/ML, CI/CD), and value stream mapping methodologies.
2. Practices Across Value Streams (~40% / ~16 Questions): Application of 12 core practices across value streams: Service Design, Software Development, Deployment, Release, Validation/Testing, Change Enablement, Incident, Problem, Service Desk, Knowledge, SLM, and Monitoring/Event Management.
3. Coordinate, Prioritize, and Source Work (~22.5% / ~9 Questions): Managing work as tickets, prioritization models (urgency vs. impact, Cost of Delay, FIFO), Kanban workflows, queue dynamics, WIP limits, Theory of Constraints bottlenecks, commercial sourcing, and buy-vs-build frameworks.

Strategic Deconstruction of Scenario Questions

To excel on Level 3 scenario questions, apply this four-step deconstruction method:

1. Dissect Customer Context and Desired Outcomes: Isolate the true customer and their target outcome. Scenarios often list multiple team frustrations, but only one primary business constraint. Determine whether the scenario prioritizes release velocity, service stability, compliance, or cost. Never pick a solution that accelerates speed if the scenario emphasizes unmanaged production outages.
2. Distinguish Practice Activities from Value Stream Steps: Do not confuse a practice with a value stream activity. A practice is a repository of organizational capabilities and resources; a value stream is the specific end-to-end journey of activities that cuts horizontally across practices to transform demand into value. When asked how to improve user request workflows, focus on handoffs and end-to-end flow rather than isolated practice tasks.
3. Avoid Local Optimization Traps: Local optimization occurs when a single team maximizes its isolated metrics at the expense of end-to-end value delivery. For example, developers automating daily releases without providing operational telemetry creates production instability. Correct answers always champion systemic flow and end-to-end quality.
4. Eliminate Plausible Distractors: Incorrect choices often cite valid ITIL concepts (e.g., "escalate to CAB", "log a problem record"). While legitimate in other situations, they are distractors if they do not resolve the specific bottleneck in the question stem.
