Which of the following is true about Ethernet crossover cables?
a. Pins 1 and 2 are reversed on the other end of the cable. b. Pins 1 and 2 on one end of the cable connect to pins 3 and 6 on the other end of the cable. c. Pins 1 and 2 on one end of the cable connect to pins 3 and 4 on the other end of the cable d. The cable can be up to 1000 meters long to cross over between buildings. |
b. Pins 1 and 2 on one end of the cable connect to pins 3 and 6 on the other end of the cable.

Each answer lists two types of devices used in 100BASE-TX network. If these devices were connected with UTP Ethernet cables, which pairs of devices would require a straight-through cable?
a. PC and router b. PC and switch c. Hub and switch d. Router and hub e.Wireless access point Ethernet ports |
b,d,e, Routers, Routers, wireless access point Ethernet ports, and PC NICs all send using pins 1 and 2, whereas hubs and switches send using pins 3 and 6. Straight-though cables are used when connecting devices that use the opposite pairs of pins to transmit data.

Which of the following is a collision domain?
a. All devices connected to an Ethernet hub b. All devices connected to an Ethernet switch c. Two PCs, with one cabled to a router Ethernet port with a crossover cable and the other PC cabled to another router Ethernet port with a crossover cable d. None of the other answers is correct. |
c. Two PCs, with one cabled to a router Ethernet port with a crossover cable and the other PC cabled to another router Ethernet port with a crossover cable

Which of the following describe a shortcoming of using hobs that is improved by instead of using switches?
a. Hubs create a single electrical bus to which all devices connect, causing the devices to share the bandwidth b. Hubs limit the maximum cable length of individual cables (relative to switches) c. Hubs allow collisions to occur when two attached devices send data at the same time. d. Hubs restrict the number of physical ports to at most eight. |
a. Hubs create a single electrical bus to which all devices connect, causing the devices to share the bandwidth
c. Hubs allow collisions to occur when two attached devices send data at the same time. |

Each manufacture puts a unique code into the first half of the address. d. The part of the address that holds this manufacturer's code is called the MAC e. The part of the address that holds this manufacturer's code is called the OUI |
b. Each manufacturer puts a unique code into the first 3 bytes of the address.
