Chapter 8 Business Telecom T/F
Routers use network layer address to forward packets between network segments.
True
A backbone network that connects many backbone networks spanning several buildings at a single location is often called an Internet backbone.
False
A hardware device that operates at the application layer is a router.
False
A switched backbone uses a bus topology
False
Backbone networks typically use lower speed circuits to interconnect a series of LANs and provide connections to other backbone networks.
False
Layer-3 switches switch messages based only on their data link layer address.
False
One advantage of a routed backbone is that is requires little management.
False
Routed backbones use switches that move packets based on data link layer addresses.
False
Routers can only connect the same type of cable.
False
Routers operate at the application layer.
False
The cable to connect BNs is usually twisted pair.
False
One difference between a switch and a router is that a router will only process messages addressed to the router (at layer 2), while a switch processes all messages.
True
Routers connect two or more network segments that use the same or different data link protocols, but the same network protocol.
True
Switches and routers are devices that can connect networks to the BN.
True
The distribution layer of a backbone connects LANs together.
True
The primary advantage of a routed backbone is that it clearly segments each part of the network connected to the backbone because each segment has its own subnet addresses that can be managed separately.
True
VLANs provide faster performance compared to switched, collapsed or routed backbone architectures.
True
A VLAN network assigns computers to LAN segments by hardware.
False
A VLAN requires the computer manager to reconfigure the physical cables to the switch if a computer is moved from one port to another port on a switch.
False
A backbone network is a high-speed network that connects many networks
True
A key advantage of a chassis switch is its flexibility.
True
A room that contains a rack of equipment for a rack-based collapsed backbone is also called the main distribution facility (MDF) or central distribution facility (CDF).
True
A routed backbone tends to be used more for large networks than VLANs, although VLAN high speed switches and this new type of LAN-BN architecture are now being considered.
True
Many routers have more sophisticated ACL software that enables the ACL to have different rules for different interfaces
True
One basic component of a backbone network is the hardware device that connects other networks to the backbone.
True
