Official blueprint
The CS0-003 exam covers 4 domains. Each domain has a defined weight — the percentage of exam questions it contributes. Courseiva has 503 practice questions mapped across these objectives.

Use this page to practise Security Operations questions for this certification. Focus on how the exam tests security operations in scenario format — understanding the why behind each answer builds more durable knowledge than memorising options.
162 practice questions available
Use this page to practise threats, attacks and vulnerabilities questions. CompTIA Security+ is scenario-heavy here — you must identify not just the attack type but the most appropriate response.
149 practice questions available
Incident Response questions always test the order of phases and the containment decision. Memorise the six phases in order and understand why containment comes before eradication — it is the most common sequence trap.
101 practice questions available
Use this page to practise Reporting and Communication questions for this certification. Focus on how the exam tests reporting and communication in scenario format — understanding the why behind each answer builds more durable knowledge than memorising options.
91 practice questions available
Start with the highest-weight domain — that's where most of your exam questions will come from. Work through each objective's practice questions until you can answer at least 85% correctly. Return to lower-weight domains last, and use the full practice test to test cross-domain recall.
