What is the maximum distance that can separate a 10BaseT node from its hub?
50 meters
100 meters
185 meters

The maximum distance between a 10BaseT node and its hub is 100 meters
When used for Ethernet, unshielded twisted pair uses what type of connector?
RG-58
RJ-45
RJ-11
RJ-45
UTP cable uses an RJ-45 connector when used for Ethernet. RG-58 is the type of coaxial cable used with 10Base2. RJ-11 is the standard four-wire connector used for regular phone lines. RS-232 is a standard for serial connectors
What is the maximum number of nodes that can be connected to a 10BaseT hub?
1024
500
100
1024
A 10BaseT hub can connect no more than 1024 nodes (computers)
Which of the following is not true of crossover cables?
They reverse the sending and receiving wire pairs.
They are used to connect hubs.
Both ends of a crossover cable are wired according to the TIA/EIA 568B standard.
Both ends of a crossover cable are wired according to the TIA/EIA 568B standard.
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 enables two hubs to communicate without colliding
Which of the following connectors are used by 10BaseFL cable? (Select two.)
SC
RJ-45
RJ-11
ST
SC
ST
10BaseFL uses two types of fiber-optic connectors called SC and ST connectors
Which networking devices can use the Spanning Tree Protocol (STP)?
Hubs
UTP cables
Switches
Switches
The Spanning Tree Protocol is unique to switches
What device directs packets based on MAC addresses?
Router
Hub
Switch
Switch
A switch uses MAC addresses to direct traffic only to the appropriate recipient
