) TCP is connection-oriented; UDP uses acknowledgements only
B.) TCP is connection-oriented; UDP is connectionless
C.) Both TCP and UDP are connection-oriented, but only TCP uses windowing D.) TCP and UDP both have sequencing, but UDP is connectionless

The correct answer(s): B
TCP provides guaranteed connection oriented delivery of packets, UDP does not.

222 What does the 'S' mean when looking at the routing table?

A.) Statically connected
B.) Directly connected
C.) Dynamically attached
D.) Shutdown route

Ans A
Statically connected routes are those that an administrator has manually entered into the routing table.

223 Why would you use static routing instead of dynamic routing?
A.) When you want automatic updates of the routing tables
B.) All the time
C.) When you have very few routes and want to conserve bandwidth
D.) When you have a gateway of last resort

Ans C
Static routes are typically used when there are very few routes and you want to conserve bandwidth. Since routing protocols are constantly sending their updates across the wire, it can cause a great deal of congestion.

224 On Cisco catalyst 5000 how would you set the second port on the controller in the first slot to full duplex?
A.) Set port duplex 1/1 full
B.) Set port duplex 1/2 full
C.) Set port duplex 0/1 full
D.) Set port duplex 0/2 full

Ans B
The syntax is: set type duplex slot/port <full/half>

225 What does the acronym ARP stand for?

A.) Address Resolution Phase
B.) ARP Resolution Protocol
C.) Address Resolution Protocol
D.) Address Recall Protocol

Ans C
The Address Resolution Protocol (ARP) resolved IP addresses to MAC addresses.

226 What is the default encapsulation of Netware 3.12?

A.) Ethernet_II
B.) 802.5
C.) 802.2
D.) 802.3

Ans C
The 802.2 Frame Type is the default frame-type for Netware 3.12.

227 Regarding frame relay, which of the following statements are true?

A.) You must use ANSI encapsulation if connecting to non-Cisco equipment B.) You must use IETF encapsulation if connecting to non-Cisco equipment C.) You must use Q.933a encapsulation if connecting to non-Cisco equipment D.) You must use Cisco encapsulation if connecting to non-Cisco equipment Ans B
Cisco's encapsulation for Frame relay is proprietary. To communicate with non-Cisco equipment when using frame-relay encapsulation, the IETF method must be used.

228 What is required to support full-duplex Ethernet?

A.) Multiple paths between multiple stations on a link
B.) Automatic sensing operation by all connected stations
C.) Loopback and collision detection disabled
D.) Full-duplex NIC cards

Ans C D
Full duplex ethernet requires that the NIC supports full-duplex, and loopback and collision detection are disabled.

229 Which layer is responsible for determining if sufficient resources for the intended communication exists?

A.) Application
B.) Network
C.) Session
D.) Presentation
E.) Transport

Ans A
The Application layer is responsible for determining if sufficient resources for the intended communication exists.

230 What are the 2 functions of the Data Link Mac layer?
A.) Handles access to shared media
B.) Manages protocol access to the physical network medium C.) Provides SAPs for higher level protocols
D.) Allows multiple devices to uniquely identify one another on the data link layer Ans B D
Media Access Control (MAC) -The MAC sublayer manages protocol access to the physical network medium. The IEEE MAC specification defines MAC addresses, which allow multiple devices to uniquely identify one another at the data link layer.

231 Describe End to End network services: (Choose all that apply) A.) Best Route selection
B.) Accomplished Segment by Segment, each segment is autonomous
C.) Flow Control & Data Integrity
D.) Best efforts packet delivery

Ans A B C D
All of the above End to End network services.

232 Which of the following provide correct information about a protocol at the transport layer of the OSI model?

A.) UDP - Provides Connectionless datagrams service
B.) TCP - Provides Connection Oriented Services
C.) SMTP - Provides Mail Exchange
D.) IP - Route determination
E.) TCP - Provides Flow Control and Error Checking
F.) FTP - Transfers of Files

Ans A B E
Only TCP and UDP work at the Transport layer of the above choices. IP is a Network layer protocol. SMTP and FTP are application layer protocols.

233 Which protocol works at the Internet layer and is responsible for making routing decisions?

A.) UDP
B.) IP
C.) TCP
D.) ARP

Ans B
Internet Protocol - IP provides routing and a single interface to the upper layers. No upper layer protocol and now lower layer protocol have any functions relating to routing. IP receives segments from the transport layer and fragments them into packets including the hosts IP
address.

234 Which layer is responsible for providing mechanisms for multiplexing upper-layer application, session establishment, and tear down of virtual circuits?

A.) Session
B.) Network
C.) Physical
D.) Transport
E.) Application
F.) Presentation

Ans D
The Transport layer does the following: Responsible for end-to-end integrity of data transmission.
