CompTIA Network+ N10-006 Q140

A network technician is attempting to connect a new host to existing manufacturing equipment on an Ethernet network. The technician is having issues trying to establish communication between the old equipment and the new host. The technician checks the cabling for breaks and finds that the CAT3 cable in use is in perfect condition. Which of the following should the technician check to ensure the new host will connect?

A. Confirm the new host is using 10GBaseSR due to the manufacturing environment
B. Confirm the new host is compatible with 10BaseT Ethernet
C. Confirm the existing 10Base2 equipment is using the proper frame type
D. Confirm that CSMA/CD is disabled on the Ethernet network

Correct Answer: B
Section: Industry standards, practices, and network theory

The question states that the equipment is old and that CAT3 cabling is being used.
10BaseT Ethernet networks are old and slow by today’s standards. 10BaseT Ethernet networks use CAT3 UTP cabling and offer a maximum bandwidth of just 10Mpbs.
A new host computer nowadays will have a network card that supports 1000Mpbs to be used with CAT5, CAT5e or CAT6 network cables in a 1000BaseT network. In this question, we need to check that the network card on the new host computer is backwardcompatible with the old 10BaseT network.
