Sneak Peek: Network+ Cram Notes & Guide Welcome to Network+ Cram Notes! This brief guide should assist you in your path to Network+ certification, offering insight into the kind of key points frequently tested on the exam. Many obscure facts show up time and time again, and though they will seldom be found useful “in real life,” CompTIA continues to test on these points. Therefore, you should have a strong, working knowledge of the information in this Sneak Peek guide; the information in here can be considered as a “cram” guide and not a complete study guide, so it is still recommended that you read our study guide before reading this Sneak Peek. The best way to utilize these Network+ cram notes is to read it several times, especially right before the exam itself. It is definite that you will find questions on the exam that cover points found only in the cram notes, so make sure you can understand and comprehend each individual point – it could be the one that makes the difference between a passing and failing score (but let’s hope not). Topologies Associate easy management, centralization, and Ethernet (802.3) with the Star topology (each node has a media connection to a hub). Associate fail/chokepoints, terminating ends (terminators), and tokens with the Token Bus and Token Ring topologies. Remember that the Mesh topology provides the most redundancy because every node has a direct connection to every other node. Ad-hoc mode in Wireless networks features this kind of topology, though it is not physical per se. Another name for a Mesh network is a "peer-to-peer network;" this terminology is not exclusive to file sharing, either. 10Base2 is usually a kind of Token Bus network, while 10BaseT is usually in the form of a Star network. On Token networks, data is passed from each node physically connected between two communicating hosts. Therefore, a break in a token bus or ring network could lead to total network failure. In comparison, a break in a Star network media would only lead to the lack of availability of the host connected to the hub. Media Plenum grade cabling provides protection from the elements, and in particular, fire. Non-plenum-cabling (i.e. most cabling) does not provide such protection. Plenum cabling is usually employed in places where the risk of fire hazard is more common, such as the ceiling or between stories in a building. It is also used in mission-critical applications. Normal 10/100/1000BaseT or TX cable has a maximum length of 100 meters, but this can be extended with the use of a powered hub or a simple repeater.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
