Networking Chapter 3

A network's physical topology refers to the arrangement of the cabling and how the devices connect to each other. True or False

A point-to-point topology is typically used for WAN connections or wireless bridges. True or False

A network's logical topology often depends on the central device's electronics. True or False

A collision can occur on a switch only if the switch is operating in full-duplex mode. True or False

In a physical bus topology, both ends of the medium must be terminated in order to prevent what? signal propagation signal bounce signal degradation collision

Which of the following is NOT an advantage of a physical star? easier network upgrades centralized monitoring and management of traffic use of faster technologies single point of failure

Which of the following is the physical topology that is daisy-chained like a bus and in which the cabling is brought around from the last device to the first device? physical bus physical star physical ring point-to-point

What is an advantage of a point-to-point topology? data travels on a dedicated link provides redundancy and fault tolerance relatively inexpensive a reliable and fast backbone

What type of logical topology is at work when using an Ethernet hub? logical bus logical ring switched topology hierarchical topology

In which topology does a central device communicate with two or more other devices and is used in WANs where a main office has connections to several branch offices via a router? logical bus logical star switched Point-to-multipoint

What is the most common topology and technology combination in use today? logical bus / Ethernet logical bus / wireless LAN logical ring / token ring switched / Ethernet

What is in an Ethernet frame's trailer? source MAC address destination MAC address frame payload cyclic redundancy check

What is the media access method used by Ethernet? CSMA/CD Token passing CSMA/CA Polling

Which of the following is true about collisions? They can only happen with switches They are a problem with Token Ring networks They can occur on Ethernet half-duplex networks Fewere computers means more collisions

When discussing Ethernet standards, what does the XBaseY terminology refer to? the length or type of cabling, the transmission speed, and the type of transmissions the transmission speed, the type of transmissions, and the length or type of cabling the transmission speed, the length or type of cabling, and the type of transmissions the length or type of cabling, the type of transmissions, and the transmission speed
