Question 1.
How does IP dynamic addressing with DHCP differ from AppleTalk dynamic addressing?

a) DHCP requires a server; AppleTalk dynamic addressing does not.
b) AppleTalk dynamic addressing works best if the network is divided into zones; DHCP does not require zones.
c) DHCP requests are not forwarded by routers; AppleTalk requests are forwarded by routers.
d) AppleTalk requests are broadcast frames; DHCP requests are multicast frames.

Answer

Question 2.
How does IP's network layer differ from AppleTalk's network layer?

a) AppleTalk's network layer is connection-oriented, whereas IP's network layer is connectionless.
b) DDP includes source and destination socket numbers, whereas IP has no socket numbers.
c) TCP sequences each byte, whereas ADSP sequences each packet.
d) AppleTalk requires zones, whereas IP has no concept of zones.

Answer

Question 3.
What is the difference between an AppleTalk GetZoneList filter and a ZIPReply filer?

a) There is no difference. They are two ways to accomplish the same thing.
b) A GetZoneList filter is implemented on routers within the core of the network; a ZIPReply filter is implemented on stub routers with LANs attached.
c) A ZIPReply filter filters zones before sending the list of zones to an end user. A GetZoneList filter filters zones before sending a list of zones to an adjacent router
d) A GetZoneList filter filters zones before sending the list of zones to an end user. A ZIPReply filter filters zones before sending a list of zones to an adjacent router.

a) DHCP requires a server; AppleTalk dynamic addressing does not.
b) AppleTalk dynamic addressing works best if the network is divided into zones; DHCP does not require zones.
c) DHCP requests are not forwarded by routers; AppleTalk requests are forwarded by routers.
d) AppleTalk requests are broadcast frames; DHCP requests are multicast frames.

Answer
a) DHCP requires a server; AppleTalk dynamic addressing does not.

Explanation
With DHCP, an administrator must set up a DHCP server. AppleTalk dynamic addressing requires no server. Answer B is incorrect because zones have nothing to do with dynamic addressing. Answer C is incorrect because DHCP requests can be forwarded by a router if the router is properly configured as a DHCP relay agent. AppleTalk requests to determine a dynamic address are never forwarded by routers. Answer D is incorrect. AppleTalk uses multicast addressing. DHCP requests are usually sent as a broadcast.

a) AppleTalk's network layer is connection-oriented, whereas IP's network layer is connectionless.
b) DDP includes source and destination socket numbers, whereas IP has no socket numbers.
c) TCP sequences each byte, whereas ADSP sequences each packet.
d) AppleTalk requires zones, whereas IP has no concept of zones.

Answer
b) DDP includes source and destination socket numbers, whereas IP has no socket numbers.

Explanation
DDP is AppleTalk's network-layer protocol and it includes socket numbers in addition to source and destination addresses. Answer A is clearly wrong because DDP is connectionless, as is IP. Answer C is wrong because it does not refer to network-layer protocols. Answer D is wrong. Zones are not required if a network is a single LAN with no routers.

b) A GetZoneList filter is implemented on routers within the core of the network; a ZIPReply filter is implemented on stub routers with LANs attached.
c) A ZIPReply filter filters zones before sending the list of zones to an end user. A GetZoneList filter filters zones before sending a list of zones to an adjacent router
d) A GetZoneList filter filters zones before sending the list of zones to an end user. A ZIPReply filter filters zones before sending a list of zones to an adjacent router.

Answer
d) A GetZoneList filter filters zones before sending the list of zones to an end user. A ZIPReply filter filters zones before sending a list of zones to an adjacent router.

Explanation
You set up GetZoneList filters on stub routers with LANs attached in order to filter zones that appear in a Macintosh user's Chooser Window. You set up ZIPReply filters to affect which zones are returned when a router that has learned about a new network sends a query to learn the zone name(s) for the new network. Answer A is clearly not true. Answers B and C are wrong because their characterization of GetZoneList and ZIPReply filters is backwards.
