CompTIA Network Plus Certification is an internationally recognized professional course. When it comes to network-related job roles, the CompTIA Network+ is state of the art certification in this domain. CompTIA is considered one of the best certifications for the experts serving the IT industry and is famous for offering vendor-neutral professional certification in around 120 countries. With a CompTIA Network plus certification, you become eligible to win several network administrator positions in any reputable facility.

Apart from an attractive salary, a CompTIA Network+ certification offers several benefits to the individuals. To study and successfully crack the CompTIA Network+ exam, the following steps are helpful.


CompTIA Network+ exam is relatively easier to pass as compared to other certification exams that haunt the beginners. That's why you can crack it in the first attempt. A minimum of 1-year experience in networking is recommended for a candidate who is willing to appear in this exam. If you are above average student and have sound research skills, you can crack it by attending online CompTIA network+ training programs, easily available. To crack the CompTIA Network+ exam, you need to acquire a rich knowledge of networking technologies. Below are the steps recommended for beginners to assure success:

STEP 1: Time Management

Managing time while solving the performance-based questions is crucial for success in the CompTIA Network Plus Certification exam. Performance-based questions are based on problem-solving and critical thinking abilities. Identify the problem before jumping directly to solve it in a hurry. Try to solve problems that you think you can solve easily and leave the puzzling one for the end. Don't waste too much time over one tricky question, putting others in a vulnerable condition of being missed due to time shortage. 

STEP 2: Identifying Hints

Learn to identify hints in the form of keywords or key phrases within a question. Pay extra attention to capitalized words or sentences as they are written in bold for some latent reasons. If you are facing trouble in answering a specific problem, then mold your plan of solving following the key phrases and capitalized words or sentences.

STEP 3: Deduction and Elimination

While solving multiple-choice questions, sometimes the right answer can be guessed after knowing the wrong answers and eliminating them based on obvious absurdness and ridiculousness. Among four choices, if you can't guess the right answer, you can eliminate the wrong ones based on their irrelative nature. There is no negative marking in CompTIA Network+ exam, so it's better to mark something rather than nothing.

STEP 4: Learn from Questions

Sometimes the answer to a previously asked question may repeat itself somehow in the form of the question asked later, or vice versa. If a hint is obvious from a new question that can give you an idea of how to solve the old one, revisit the leftover that you had not attempted for the first time.

After preparing theoretical aspects of the course, the next step for you is to get hands-on experience with a lab environment. Cybrary’s Insider Pro subscription contains all sorts of cybersecurity stuff. It also includes a batch of labs rich in CompTIA Network+ certification course material. The simulations they provide can let you save a lot of money that you otherwise might spend on equipment.


This course is engineered for entry-level network support and administration experts with a fundamental knowledge of network components, including both hardware and software, who are willing to enhance their expertise and understanding of broad networking concepts and enrich their skill set for a successful launch in the career of network administration. 

An average student willing to crack CompTIA Network+ exam should have a minimum of 1 year of professional IT support experience. Having CompTIA A+ certification or relevant knowledge is also helpful in the preparation process but not mandatory
