The CompTIA Network+ is about building specialists' abilities so that they are effective in developing and executing functional networks. This considers vital networking devices like routers and switches as well as security and troubleshooting issues.

About Certification

The Network+ certification is intended for beginners, as being an entry-level certificate, it cultivates their knowledge in the field and prepares them for relevant tasks. Still, before going for it, the CompTIA A+ certification or an equivalent is recommended. Also, an applicant needs prior experience starting from 9 months in networking administration or support. In addition, to become Network+ certified, candidates need to pass N10-007 exam.

About Certification Exam

Exam N10-007 is expected to contain 90 questions and they will be of various types, such as performance-based, drag and drops as well as multiple choices. The passing mark is 720 out of 900 points. The timing necessary to complete the official test is 1.5 hours. Finally, the Network+ exam costs $329 to register.

CompTIA Network+ Topics

The Network+ certification guarantees that you are proficient in five unique topics. A look at each of them will bring a better understanding of the same. They are covered as follows:

• Networking Concepts

  This begins with the usage of ports in addition to protocols. Such include SNMP, SSH, RDP, DHCP, TELNET, HTTP, LDAP, and HTTPS. There is also the aspect of protocol types, for example, TCP, ICMP, IP, and UDP. The next domain looks at gadgets, apps, protocols as well as services within their proper OSI layers. This is where Layer 1 to Layer 7 protocols are checked. Other sections give exam-takers a chance to grasp features of routers and switches, appropriate constituents of IP addressing, network types, topologies as well as technologies, and wireless technologies. There are also areas that allow exploring of cloud concepts, network services, and their functions.

• Infrastructure

  Being part of the Network+ certification, this topic about Infrastructure begins by looking at how the right cabling solution can be deployed. These are solutions like media types, plenum, PVC, connector types, transceivers, copper cabling, termination points, etc. It's followed by issues about installing and configuring networking devices where firewalls, routers, switches, modems, hubs, and bridges are captured. To follow is how advanced gadgets for networking can be used. Included as well are multilayer switch, proxy server, load balancer, VPN concentrator, VoIP PBX, etc. You will also experience the uses of technologies geared for networking and virtualization. These cover elements of virtual networking like a virtual switch, virtual NIC, virtual firewall, and types of networking storage. The final domain concerns itself with WAN technologies.

• Network Operations

  First, this segment reviews managing networks using proper diagrams as well as documentation. Here, you will see diagram symbols, rack diagrams, labeling, etc. Second, it delves into concepts concerning disaster recovery and continuity where things to look at include power management, backups, and recovery. Third, the focus is on common procedures for scanning, patching, and monitoring as well as giving a summary of the outputs expected. Fourth, candidates come to learn about how mechanisms for remote access can be used. Finally, one must be great at identifying policies on top of best practices.

• Network Security

  Concerning the Network+ certification, the aspect of security is given enough focus as well. One of the domains exploring it regards physical gadgets of security used during detection and prevention. Another one reveals access controls and authentication procedures. Explored in this case are measures like authentication, access control, and authorization. Also, ways of securing basic wireless networks is another point of concern. Candidates will investigate more about WPA, CCMP-AES, MAC filtering, and others. After this, they will learn the forms of network attacks that are most common. They will look into DoS, insider threat, social engineering, evil twin, spoofing, deauthentication, VLAN hopping, DNS poisoning, etc. The next thing of interest is how device hardening related to networks is implemented. And the final part is to cover common methods of mitigation like signature management, network segmentation, and device hardening in addition to their uses.

• Network Troubleshooting & Tools

  This topic breaks down into five domains. The first one concerns the techniques of network troubleshooting. You will be made to know how to detect a problem, followed by establishing a theory on what may have caused it, testing that theory to know what the cause could be, and settling on the appropriate action to take in resolving it. Next is to apply the solution, verify if the system is fully functional, and where possible, implement measures that will help prevent problems. The second part of the topic enables you to delve into the usage of the right tools such as hardware and software. The third part is concerning troubleshooting issues that touch connectivity as well as performance. This includes attenuation, transceiver mismatch, latency, jitter, EMI, and damaged cables. For the fourth area, candidates will establish abilities in troubleshooting commonly occurring wireless connectivity issues and those that touch on performance. You will experience matters like refraction, reflection, interference, absorption, jitter, channel overlap, and wrong passphrase. The fifth and last bit concerns troubleshooting common issues affecting network service. This includes an incorrect gateway, incorrect time, incorrect netmask, IP addresses that are expired, and rogue DHCP server, among others.

Career Opportunities and Yearly Salary

IT infrastructure is a career field that is yet to be exploited fully. Networking in itself demands more talent because of the growing adoption of evolving technologies. By earning the Network+ certification, you hand yourself a chance of a lifetime. Organizations are searching for individuals with this certificate and who can offer the solutions they need regarding networking. In this case, they wish to fill positions such as a network administrator, junior systems engineer, computer technician, network field tech, and network analyst. When it comes to compensation, you will be looking at about $67k annually as PayScale.com proposes.

Career Path

CompTIA has lined up their certifications for those who may be interested to explore advanced IT skills. The Network+ is required for the Security+ certification. Once you have exploited networking and received the relevant certification, it means that you are now ready to acquire helpful abilities in cybersecurity. This is another area that continues to see a lot of jostling for talent by firms globally. This means the CompTIA Security+ is what you should exploit next.
