When comparing IPv4 to IPv6, which of the following statements is true IPv4 uses a 32-bit address scheme, while IPv6 uses a 128-bit address scheme. In IPv6-enabled networks, static addressing is no longer allowed. FALSE Without IPv4's network address translation (NAT), IPv6 offers simpler packet construction and better support for peer...

NCTI 2-3 Questions and Answers 100% Pass What is the difference between the FTTN and FTTC topologies? An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. What are the three categories of the fiber-optic cable used to identify the location of the fiber in the network? Truck, branch, and drop Which type of fiber topology used in a PON places the PON splitters at the headend while providing one designated fiber for every customer premise?...

NCTI WIFI (2022/2023) Rated A+ Notes Single input, single output (SISO) - Most systems have one radio and one antenna, and some systems have one radio and two antennas. Multiple input, multiple output (MIMO) - These systems use multiple radio chains in a single wireless chipset. Multi-user MIMO (MU-MIMO) - These systems use each radio chain on an access point to transmit to a unique client.Correct answer: Wired Equivalent Protection (WEP) - This type of security setup should never be use...

NCTI RSC II CABLE NETWORK OVERVIEW: Understanding the Feeder System Questions and Answers with Verified Solutions What is one of the differences between tree-and-branch and hybrid fiber/coax (HFC) DESIGNS? Bandwidth in the downstream path. In the tree-and-branch design, the cable signal in the downstream path leaves the trunk at the bridge amplifier. There, It makes a transition to the feeder's domain, and the signal splits. What is the maximum number of output ports the split signal ca...
