Hands-on Projects
Project 4-1 – Project 4-6
No answers necessary.
Case Projects
Case Project 1
Because a 32-bit bus mastering NIC with additional on-board RAM gives you about as much speed as you can get when attaching a server to a cable segment, it definitely produces the required result of handling network traffic with reasonable response time. This also helps to guarantee that the server won't slow the network down. However, because it would be cheaper (in fact half the cost) to use plain-vanilla NICs on the relatively idle segments, this solution fails to keep the hardware costs to a minimum. Thus, the correct answer is b, which produces the required result but only one of the optional desired results.
Case Project 2
Check that all NICs support 100BaseT and if not, they should be replaced. The hub must support 100BaseT as well. A 10/100 hub could be purchased and that would allow a gradual migration to 100BaseT until all NICs are brought up to that speed.
Case Project 3
SNMP, IPSec, and QOS--to name a few
Case Project 4
Answers will vary, but some features will include hot-swappable, SNMP, QOS, and on-board processor.
