Are you looking to move ahead in a networking job? Are you interested in a career with steady and ongoing opportunities? Then the CompTIA’s Network+ vendor-neutral certification might be a good choice. The credential can be a sure help to a successful network engineer or network administrator career.

According to the official website, the certification “helps develop a career in IT infrastructure covering troubleshooting, configuring, and managing networks,” which are duties central to those roles. The program helps professionals develop and update skill sets that CompTIA believes are essential for qualified IT professionals to master in order to be successful in a variety of entry-level and intermediate networking positions.

The Network+ certification can also be used as a stepping-stone to more advanced networking credentials, allowing a professional to stand out in the field and increase his or her credibility as an engineer or technician in network support and/or administration. From a job perspective, the CompTIA Network+ certification is able to open doors to plenty of employment opportunities. In fact, when evaluating prospective IT candidates, employers frequently look to this certification as an important criterion to fill network-related job roles.

In order to meet the demands of a field in constant evolution, the certification is updated periodically to reflect the skills and duties required today. In fact, the latest version of CompTIA Network+ was released in March 2018, when the new N10-007 replaced the older version (N10-006). The new test provides learning objectives that focus more on security and network resiliency. However, test takers should familiarize themselves with all new domain topics to be better prepared to take and pass the credential exam.

What Domains Are Covered on the Updated Network+ Exam?

 Here’s what you need to know about the N10-007 exam.

The older exam version concentrated mostly on technical aspects such as the configuration and management of network devices, as well as technologies including the cloud, virtualization and mobile devices. N10-007, instead, expands the focus to include a stronger emphasis on security and how to create wired and wireless networks that are not only efficient but also resilient. It also concentrates on the necessary interaction of network professionals with IT security staff. Newest advances in cloud computing and virtualizations are also covered, together with their proper implementation and best practices.

Therefore, reviewing these topics to pass the test and obtain the credential can help practitioners to understand today’s challenges for a network professional and the knowledge and skills that employers expect from them.

Exam Objectives (N10-006 vs N10-007)

Because CompTIA Network+ is accredited by the American National Standards Institute (ANSI) to show compliance with the International Organization for Standardization (ISO) 17024 Standard, the exam objectives undergo regular reviews and updates. As such, this enables one to stay current with new and evolving technologies and remain a sought-after network expert.
