Actual exam question from CompTIA's 220-1101

Question #: 337
Topic #: 1

A technician installed a Cat 5 UTP cable approximately 275ft (84m) from a network switch in an office to a workstation located on a factory floor. The technician sees both a flashing green LED and a flashing orange LED on the workstation's NIC. Which of the following should the technician do FIRST?

A. Check for loose connections, pinched bends, and physical damage.
B. Install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run.
C. Replace the entire run of Cat 5 UTP cable with Cat 5 STP cable.
D. Upgrade the entire cable run to multimode fiber.

Selected Answer: A

less than 100m so its below its ethernet limitation, the orange and green lights meaning there is connection but there are issues like packets loss. And always CHECK first... so A

A is wrong B is correct The correct answer is B. Install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run. The problem is most likely caused by the excessive length of the Cat 5 UTP cable, which exceeds the maximum limit of 100 meters (328 feet) for Ethernet over twisted pair12. This can result in signal degradation, interference, and packet loss, which can affect the network performance and connectivity. The flashing green LED indicates that the NIC is receiving data, while the flashing orange LED indicates that the NIC is sending data3. However, these LEDs do not indicate the quality or speed of the data transmission, which may be poor due to the long cable run.

The best solution is to install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run. A powered hub is a device that can amplify and regenerate the signal, as well as provide additional ports for connecting more devices. A powered hub can extend the effective range of the cable and improve the network performance and connectivity1.

The other options are not the best solutions for this problem. Checking for loose connections, pinched bends, and physical damage is a good troubleshooting step, but it is unlikely to solve the problem if the cable is too long. Replacing the entire run of Cat 5 UTP cable with Cat 5 STP cable may reduce some interference, but it will not solve the problem of signal degradation due to the length. Upgrading the entire cable run to multimode fiber may provide better performance and range, but it will also require replacing the NICs and switches, which will be costly and time-consuming.

The technician should check the link status and cable connections as the first step. The flashing green LED indicates a successful link between the NIC (Network Interface Card) and the switch, while the flashing orange LED typically signifies network activity. However, this doesn’t guarantee proper communication. Here’s what the technician should do: Verify Cable Connections: Ensure that both ends of the Cat 5 UTP cable are securely connected to the NIC port on the workstation and the switch port in the office. Check for any loose or damaged connectors. Inspect Cable Length: Cat 5 UTP cables have a maximum recommended length of 100 meters (328 feet). Since the cable is approximately 275 feet (84 meters), it’s within the acceptable range. However, if there are additional patch panels or connectors along the route, the total cable length should be considered.
