20+ practice questions focused on Endpoints and Media Types — one of the most tested topics on the Cisco Certified Support Technician - Networking exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Endpoints and Media Types PracticeWhen creating a crossover cable using the TIA/EIA 568A and 568B standards, which TWO pairs of wires must be swapped at one end of the cable? (Choose TWO.)
Explanation: In a crossover cable, the transmit and receive pairs must be reversed at one end so that the TX of one device connects to the RX of the other. Under TIA/EIA 568A/568B, pins 1 and 2 carry the Green pair in 568A (or Orange in 568B), and pins 3 and 6 carry the Orange pair in 568A (or Green in 568B), so swapping the Green pair (option A) and the Orange pair (option C) exchanges the TX and RX paths. The Blue pair (option B) and Brown pair (option D) are not used for 10/100 Mbps Ethernet TX/RX and remain on pins 4-5 and 7-8 in both standards, so they are not swapped. Option E is invalid because TIA/EIA 568A/568B cables use only eight pins (1-8), not pins 9 and 10, and there is no Red pair in these standards.
A technician is troubleshooting a 'no link' light on a laptop connected to a wall jack. Which THREE physical layer issues could be the cause?
Explanation: While an administratively disabled port results in a 'no link' light, it is a configuration setting (Data Link layer) rather than a physical layer fault. A physical layer issue refers to the medium, connectors, or hardware signaling. A better third option would be a duplex mismatch or a faulty transceiver/NIC.
A technician is deploying a new wireless access point in a warehouse. The AP supports 802.11n and must provide coverage across a large open area with metal shelving. Which antenna type should be selected to best meet the coverage requirement?
Explanation: An omnidirectional antenna is designed to radiate signals uniformly in all directions on the horizontal plane, which is essential for covering a wide area like a warehouse. Unlike directional antennas that focus energy in a single direction, an omnidirectional antenna ensures that multiple client devices spread across the space can connect reliably, even with some obstructions.
A network engineer is connecting a Cisco switch to a server that requires 10 Gbps throughput over a distance of 150 meters. The switch supports SFP+ transceivers. Which type of transceiver and cabling should be used to meet these requirements?
Explanation: 10GBASE-SR with OM3 multimode fiber is the most appropriate solution because it supports 10 Gbps over distances up to 300 meters, meeting the 150-meter requirement. It balances performance and cost, unlike 10GBASE-T which is limited to 100 meters, or 10GBASE-LR which is overkill and more expensive for such a short run.
A network technician is connecting a Cisco Catalyst 2960 switch to a Cisco 2900 Series router using a copper cable. The switch port is a 10/100/1000BASE-T port, and the router interface is also 10/100/1000BASE-T. The technician wants to ensure the link operates at full duplex and the highest possible speed. Which type of cable should the technician use?
Explanation: The correct choice is a straight-through cable because the connection is between a switch and a router, which are different device types. Straight-through cables map pins 1-1, 2-2, etc., allowing the transmit pairs on one device to connect to the receive pairs on the other. This enables auto-negotiation to achieve full duplex and the highest speed. Crossover cables are for like devices, rollover for console, and coaxial is obsolete for this purpose.
