Technical certification mock tests
131 full-length mock tests across 16 awarding bodies. Browse them three ways — by subject, by the job you are working towards, or by the badge your employer asked for. They are the same catalogue seen from three sides.
What the exam is about.
Start here if you know the subject but not yet which badge carries it.
Cloud
Designing, running and securing infrastructure on someone else's hardware — the largest and fastest-moving family in the catalogue.
Security
Defensive and offensive security, governance and audit. The exams that gate most security roles, and several that gate the salary band above.
Networking
Routing, switching, SD-WAN and the operations of a real network — where the vendor's own kit is still the qualification employers look for.
DevOps & Platform
Automation, pipelines, containers and the platforms teams build on top of a cloud rather than beside it.
Data & AI
Data engineering, analytics and the machine-learning credentials that have appeared in the last three years.
ERP & Business Apps
Finance, supply chain and CRM platforms — the certifications that follow an implementation rather than a technology.
Project & Service Management
How the work is run rather than what it runs on: delivery, risk, agile practice and service management.
The ladder, in order.
Each path says what to sit first, what follows, and what to leave until you have the experience to answer it honestly.
Cloud Architect
Design systems that survive a failure you did not plan for, at a cost someone will actually sign off.
Cloud Developer
Write the services rather than run them — and find out where the platform will bill you for a design you thought was elegant.
Cloud Security Engineer
Identity, network boundaries and key management on infrastructure you do not own, across the three providers that host most of it.
DevOps & Platform Engineer
Pipelines, containers and the platform other engineers deploy onto.
IT Support to Sysadmin
The ladder most people actually start on: fix the desk, then the server, then the estate.
Microsoft 365 Administrator
Run the tenant every office actually lives in — identity, mail, compliance, and the calls that come with them.
Power Platform Consultant
Build the internal tooling a business asks for on Monday and wants by Friday, without it turning back into a spreadsheet.
Network Engineer
From a first switch to a routed, segmented, software-defined network you are on call for.
Network Automation Engineer
Stop configuring boxes by hand. The network becomes code, and the code becomes the thing you are reviewed on.
Data Centre Engineer
Fabric, compute and storage in the building the cloud is also made of.
Collaboration Engineer
Voice, video, and the meeting that has to work when everyone dials in at once.
Security Analyst
Detect, triage and respond — the ladder most SOC and blue-team roles are recruited against.
Penetration Tester
Break it on purpose, in scope, and write the report that makes someone fix it.
AI Governance & Assurance
Audit, risk and control for systems nobody can fully explain — the roles organisations are creating faster than they can fill them.
Data Engineer
Move data reliably, on a schedule, and be the person who knows why last night's load is late.
Data Analyst
Turn the warehouse into an answer someone can act on, and a chart that does not mislead them.
Database Administrator
Keep the store correct, fast and recoverable — the job everyone notices only when it is not being done.
AI Engineer
Build, ship and run systems with a model inside them — from the first prompt to the GPU cluster it eventually needs.
Machine Learning Engineer
Train it, evaluate it honestly, then keep it working once real traffic reaches it.
Dynamics 365 Consultant
Configure the finance and supply-chain system a business runs on, and own the gap between what it does and what they asked for.
CRM & Customer Experience Consultant
The sales, service and field side of the same platform — where the process matters more than the schema.
Project Manager
Run the delivery rather than the technology — predictive, agile, or the hybrid most organisations actually use.
IT Service Manager
Keep the service running as a product: incidents, changes, and the expectations set around them.
Scrum & Agile Practitioner
Facilitate the delivery rather than direct it, on the two frameworks most teams are actually running.
Whoever awards it.
Start here if someone has already told you the exam code.
