4
What three categories of problems do most networks fall into?
Most problems can be attributed to media, protocols, or transport.
5
What are the two contrasting factors in determining network design?
Cost and availability.
6
Why are desktop protocols least desirable for a large network?
Desktop protocols tie up large quantities of bandwidth with broadcasts. Excessive
broadcasts can render the network inefficient.
7
What solution should the CCDP employ when addressing a network with media
contention?
Switches.
8
When might an ATM switch improve an internetwork's design and performance?
For networks that require Quality of Service delivery.
9
What device should be used to filter broadcasts and multicasts?
Router.
10
What is the difference between a broadcast domain and a bandwidth domain?
A bandwidth domain consists of all traffic associated with a single port on a bridge or
switch. A broadcast domain consists of all traffic associated with a single port on a router.
11
What issues should you address when designing a campus LAN?
Server and client end stations.
Network infrastructure.
Network management.
Business concerns.
12
How can a VLAN improve network performance?
A VLAN isolates bandwidth segments. So, one user or a group of users who require large
amounts of bandwidth will not impact network performance for the rest of the network.
13
What device controls broadcasts and multicasts?
Router.
14
Name two protocols that are not recommended for WAN design.
NetBEUI and AppleTalk.
