Ethernet hubs take an incoming packet and \_\_\_\_ it out to the other connected ports. A) Amplify B) Repeat C) Filter D) Distort
B) Repeat. Hubs are nothing more than multi-port repeaters
What is appended to the beginning of the Ethernet frame? A) MAC Address B) Length C) Preamble D) CRC
C) Preamble - Appended to the front of the Ethernet frame is the PREAMBLE.
What type of bus does 10BaseT use? A) Bus B) Ring C) Star bus D) Bus Ring
C) Star Bus. 10BaseT uses a Star-Bus Topology
What is the maximum distance that can seperate a 10BaseT node from its hub? A) 50 Meters B) 100 Meters C) 180 Meters D) 200 Meters
B) 100 Meters. The Maximum distance between 10BaseT node and its hub is 100 Meters.
When used for Ethernet, un-shielded twisted pair uses what type of connector? A) RG-58 B) RJ-45 C) RJ-11 D) RS-232
B) UTP cable uses an RJ-45 connector when used for Ethernet.
What is the Maximum number of nodes that can be connected to a 10BaseT hub? A) 1024 B) 500 C) 100 D) 185
A) 1024. A 10BaseT hub can connect no more than 1024 nodes (computers)
Which of the following is not true of crossover cables?
A. They are a type of twisted pair cabling.
B. They reverse the sending and receiving wire pairs.
C. The are used to connect hubs.
D. Both ends of a crossover cable are wired according to the TIA/EIA 568B standard.
D. One end of a crossover cable is wired according to the TIA/EIA 568B standard; the other is wired according to the TIA/EIA 568A standard. This is what crosses the wire pairs and enable two hubs to communicate without colliding.
Which of the following connectors are uses by 10BaseFL cable? (Select Two) A. SC B. RJ-45 C. RJ-11 D. ST
A, D. 10BaseFL uses two types of fiber-optic connectors called SC and SDT connectors.

D) Switches. The Spanning Tree Protocol is unique to SWITCHES.
What device directs packet based on MAC Address? A) Router B) Hub C) Repeater D) Switch
D) Switch. A switch uses MAC addresses to direct traffic only to the appropriate recipient.
