Explanation: Data is transmitted on copper cables as electrical pulses. A detector in the network interface of a destination device must receive a signal that can be successfully decoded to match the signal sent. However, the farther the signal travels, the more it deteriorates. This is referred to as signal attenuation.
Explanation: Crosstalk is a type of noise, or interference that occurs when signal transmission on one wire interferes with another wire. When current flows through a wire a magnetic field is produced. The produced magnetic field will interface the signal carried in the adjacent wire. 10. Refer to the graphic.
Explanation: Issuing the command ipconfig /all from the PC0 command prompt displays the IPv4 address and MAC address. When the IPv4 address 10.1.1.5 is pinged from PC0, the switch stores the source MAC address (from PC0) along with the port to which PC0 is connected. When the destination reply is received, the switch takes the destination MAC ...
Explanation: Network A needs to use 192.168.0.128 /25, which yields 128 host addresses. Network B needs to use 192.168.0.0 /26, which yields 64 host addresses. Network C needs to use 192.168.0.96 /27, which yields 32 host addresses. Network D needs to use 192.168.0.80/30, which yields 4 host addresses. 18.
ENetwork Chapter 10 – CCNA Exploration: Network Fundamentals (Version 4.0) 1. Refer to the exhibit. A student working in the lab selects a cable that is wired as shown. Which connection types can successfully be made with this cable?
Explanation: Optical fiber cable transmits data over longer distances and at higher bandwidths than any other networking media. Unlike copper wires, fiber-optic cable can transmit signals with less attenuation and is completely immune to EMI and RFI.

Which subnet mask would be assigned to the network address of 192.168.32.0 to provide 254 useable host addresses per subnetwork?
Question: What OSI physical layer term describes the physical medium for microwave transmissions? air. goodput. latency. throughput. Exam with this question: CCNA 1 v7 Checkpoint Exam: Ethernet Concepts Exam Answers. ← Previous Question.
In most platforms running IOS 12.0 or later, Cisco Express Forwarding is enabled by default. Cisco Express Forwarding eliminates the need for the recursive lookup. If Cisco Express Forwarding is disabled, multiaccess network interfaces require fully specified static routes in order to avoid inconsistencies in their routing tables.
Explanation: Fast-forward switching begins to forward a frame after reading the destination MAC address, resulting in the lowest latency. Fragment-free reads the first 64 bytes before forwarding. Store-and-forward has the highest latency because it reads the entire frame before beginning to forward it. Both fragment-free and fast-forward are ...
