Answers

1.

C Routers use IP and logical addressing to determine packet routing.

2.

B FTP is used to both send and receive data between hosts on the network.

3.

C SMTP is used to send or transport mail messages between hosts of a network.

4.

A Telnet allows for remote access and terminal emulation between hosts.

5.

C TCP uses virtual circuits to send sequenced, acknowledged, reliable data between hosts. UDP sends data unsequenced, unacknowledged, unreliable, but with low overhead.

6.

D Address Resolution Protocol is the correct term.

7.

B RARP is the protocol used by diskless workstations to determine their IP address given their MAC address.

8.

D, E TCP and UDP are the protocols used at the Transport layer in the TCP/IP protocol suite. The Host-to-Host layer functions like the Transport layer in the OSI model. In fact, the term “Transport layer” is often used interchangeably with Host-to-Host.

9.

E UDP is the connectionless Transport layer protocol while TCP is the connection-oriented Transport layer protocol. The Host-to-Host layer functions like the Transport layer in the OSI model. In fact, the term “Transport layer” is often used interchangeably with Host-to-Host.

10.

C SPX is the protocol used by the IPX/SPX protocol suite for connection-oriented data delivery at the Transport layer. The Host-to- Host layer functions like the Transport layer in the OSI model. In fact, the term “Transport layer” is often used interchangeably with Host-to-Host.

11.

B, C IP is used for the logical addressing of network devices and destination of network routes by routers.

12.

A, D NetWare servers always respond to local GNS broadcast requests by clients, and Cisco routers can be configured to respond to clients where NetWare servers do not exist on their local networks.

13.

A IPX is a protocol designed very much like UDP and is connectionless.

14.

C Every 60 seconds, servers exchange their SAP table entries to build a comprehensive list of network services.

15.

B The first 32 bits represent the assignable IPX network address, and the final 48 bits represent the node address, also known as the MAC address.

16.

B TCP is most like SPX and uses connection-oriented, sequenced, acknowledged, reliable, virtual circuits for data delivery.

17.

A, C Both IPX and IP are responsible for logical addressing at Layer 3 of the OSI model and are used by hosts, routers, and routing protocols to determine host and network addressing.

18.

C 10 bytes (80 bits) is the length of an IPX address using the 32-bit network address and the 48-bit node address.

19.

C, E SLARP is rare in today’s networks but was designed to resolve network addresses to MAC addresses and operates much like ARP.

20.

D An IPX address includes the node’s MAC addresses and eliminates the need for logical-to-physical address resolution used in IP networks.
