Topic #: 2
A help desk technician is tasked with moving a user's computer to a makeshift office for renovations. Upon moving the computer, the technician notices the network card will not utilize anything beyond 10Mbps half- duplex. Which of the following is the most likely issue?

Suggested Answer: D Vote an answer

Hubs operate in half-duplex mode and are limited to low speeds like 10Mbps, making them the most likely cause for the network card's performance issue.
Why Not A (DSL): DSL relates to internet connectivity, not local network hardware.
Why Not B (Unmanaged switch): Unmanaged switches typically support full-duplex and higher speeds than
10Mbps.
Why Not C (NIC teaming): NIC teaming increases bandwidth and redundancy, and is not relevant to this issue.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.2, networking hardware.
