While they share some common ground, each serves a distinct purpose and targets different career stages. Practice with the free CompTIA practice test on PracticeTestGeeks (18 questions with answer explanations).
CompTIA A+ (CompTIA A+ Certification) is a widely recognized credential in its field. It validates foundational IT skills including hardware, software, networking, and troubleshooting, making it the standard starting point for IT careers.
Security+ (CompTIA Security+ Certification) serves a complementary but distinct purpose. It is the global benchmark for validating baseline cybersecurity skills, covering threat detection, risk management, and security architecture.
Understanding the differences between these two certifications is essential for making an informed career decision. Let's examine each aspect in detail, from exam structure and difficulty to long-term earning potential. CompTIA A+ Practice Test and Security+ Practice Test are both available on our platform to help you prepare for whichever path you choose.

When comparing difficulty, the CompTIA A+ is rated moderate while the Security+ is considered moderate-hard. This difference reflects the depth and breadth of knowledge each exam tests.
The CompTIA A+ exam consists of 90 per exam (2 exams) questions with a passing score of 675/900 (Core 1), 700/900 (Core 2). Candidates typically need 3–6 months self-study of dedicated preparation to feel confident on exam day.
The Security+ exam features Up to 90 questions with a passing threshold of 750/900. Most candidates invest 2–4 months study in preparation, though this can vary based on prior experience and study habits.
Both exams reward consistent, structured study. Practice tests are particularly valuable for building familiarity with question formats and identifying knowledge gaps before test day.
Career earnings are a major factor when choosing between certifications. CompTIA A+ holders can expect to earn $45,000–$60,000 annually, while Security+ credential holders typically earn $65,000–$85,000.
These figures represent national averages and can vary significantly based on location, years of experience, industry sector, and additional certifications held. Metropolitan areas and specialized roles often command premium salaries.
Beyond base salary, consider the long-term career trajectory. Some certifications open doors to management roles, specialized positions, or consulting opportunities that can significantly increase earning potential over time.
CompTIA A+ Prerequisites:
Security+ Prerequisites:
Be sure to verify the most current requirements with the official certifying body, as prerequisites can change. Some organizations offer waivers or alternative pathways for candidates with significant work experience.
For most professionals, starting with CompTIA A+ is the recommended path. It provides a solid foundation with a lower barrier to entry, building the knowledge base you need for more advanced certifications later.
Once you have your CompTIA A+ credential and some practical experience, moving on to Security+ becomes more achievable. The experience you gain working with your CompTIA A+ will make the Security+ study material more relatable and easier to grasp.
However, if you already have significant experience in the field, you may be able to pursue Security+ directly without CompTIA A+ as a prerequisite.
No matter which certification you choose, thorough preparation is the key to passing on your first attempt. Practice tests help you identify weak areas, build confidence, and get familiar with the exam format.
We offer comprehensive practice tests for both certifications:
Each practice test includes detailed answer explanations and hints to guide your study. Track your progress over multiple attempts to ensure you are fully prepared on exam day.
| Pros | Cons |
|---|---|
| CompTIA has a defined, publicly available content blueprint — candidates know exactly what to prepare for | The scope of tested content requires substantial preparation time that competes with existing professional or academic commitments |
| Multiple preparation pathways (self-study, courses, coaching) accommodate different learning styles and schedules | No single resource covers the full content scope — candidates typically need multiple study tools for comprehensive preparation |
| A growing ecosystem of study resources means candidates at any budget level can access quality preparation materials | Test anxiety and exam-day performance variability mean preparation effort does not always translate linearly to scores |
| Clear score reporting allows candidates to identify specific strengths and weaknesses for targeted remediation | Registration, preparation, and potential retake costs accumulate into a significant financial investment |
| Professional recognition associated with strong performance provides tangible career and academic benefits | Content and format can change between exam versions, making older preparation materials less reliable |

Which of the following describes a cloud computing delivery model in which clients rent computer resources from vendors that own and maintain all essential equipment and software rather than purchasing hardware and software?
Answer: A. IaaS
Infrastructure as a Service (IaaS) is a cloud computing model where a vendor provides virtualized computing resources over the internet. Clients rent fundamental IT infrastructure like virtual machines, storage, and networks, rather than purchasing and maintaining their own hardware. This allows clients to manage their own operating systems and applications while the vendor handles the underlying physical infrastructure.
