CASE4

1.Since, you purchased a new PC that includes serial mouse,
an internal modem,two hard drives and two SCSI controllers. The
following IRQ remain eligible for use with a NIC are
IRQ3 = for COM2/COM4 or bus Mouses
IRQ4 = for COM1/COM2
IRQ10 = used for primary SCSI controller
IRQ11 = used for secondary SCSI controller

2.In this case it's good to get a minimun cost, it is good to buy a 32 bit bus-
mastering NICs with additionalRAM for all segments.
b.The required result but only one of the optional desired results, i'll use a
minimum cost for the network.
c.To get the required result but neither of the optional desired result, and buy
a expensive hardware for the Network.
d.To get the proposed solution but does not produce the required result.

3. Bob should run a dedicated cable from the server to Bob's machine, and put him on
his own network segment. That way, his laggard performance won't affect anyone
else. 8 bit NE1000 with a 32 bit NE3200 EISA card, he may encounter problems.He
most choice (b).

4. In this case I choice (b) Remove all non essential adapters and install the NIC
then use whateverIRQ's are available to install as many of the other adapters as
you can getworking.There are different method of checking the card to see whether
otherdevices can be found. Use Network Neighborhood and check for all devices on
thenetwork. Another method is to ping known devices by their IP address

CASE #3

1.XYZ Corp’s Nashua, NH, facilities are two office building located 400 feet apart, each with its own LAN. To connect the two networks, you plan to dig a trench and lay cable in conduit between the two buildings. You want to use fiber-optic cable, but your budget-conscious facilities manager wants to use thin wire Ethernet. What’s the best reason you can use to justify fiber-optic cable in this case?

Ans: D – Fiber-optic leaves more room for growth, and for future needs for increased bandwidth, than thinnest does.

2.Ans: B – The proposed solution delivers the required result but only one of the two optional desired results. Why? Because Fiber optics is possible to support the speed of up to 100 mbps.
Required result: The network must support speed of up to 100 Mbps.
Optional desired result: The network should be as secure as possible from electronic eavesdropping. To stay within TVBCA’s budget, the network should also be inexpensive as possible.
3.Ans: B - The proposed solution deliver the required result and only one of the two optional desired solution. The Category 5 UTP is capable to operate at speeds of up to 100 mbps.

4.Ans: B - The proposed solution deliver the required result and only one of the two optional desired result.
