Flow Control and Networking Fundamentals

The assignment content covers various topics in computer networking, including Flow Control, ATM, MPLS, IP V6, Frame Relay, X.25, and OSI layers. It asks multiple-choice questions on these topics, covering characteristics of ATM, correct statements about MPLS, motivations behind the development of IP V6, and more.

1. The object of the “Flow Control” is to allow the _______________Receiver
To control the rate of the transmission.
1. Sender
2. Receiver
3. Network Manager
4. Connection identity
2. Which are the characteristics assorted with ATM?
1. CIR, EIR and DLCI
2. QoS, AAL and OC3
3. Packet, Pads and three layers of protocols
4. Tokens, bridges and dual rings
3. Which is a correct statement about MPLS?
1. It provides a layer 2 label swapping alternative to IP
2. It switches IP packets along a path selected by the routing protocol
3. It is most useful in the control core portion of the internet and intranets
4. All of the above
4. The major motivation in the development of IP V6 is
1. Have many more available registered IP addresses
2. Increase the Maxiumum allowable size of IP packets
3. Provide IP virtual circuit services
4. Reduce the size of IP addresses
5. Frame relay circuits may be configured to have a committed information rate and
_____________ information rate.
1. Excess
2. Marginal
3. Maximum
4. Incremental
6. Which is an example of an IP address:
1. 300.25
2. 192.100.68.14
3. net19,host12
4. ox32-45-B8-OE-63

7. The legacy world-wide form of packets-switching network is called X._____,
which has been replaced in many instances by frame relay.
8. A frame relay connection may have a CIR and a(n) _______, often providing
capabilities comparable to fractional T1/E1 links (at a considerable cost reduction).
9. If a frame relay network becomes congested, some frames may be discarded.
(which ones?)
10. “ AAL5” is part of a networking technology called _______________.
11. ATM sends data in small units called _______, which consists of a ____ byte
(octet) header and a _____ byte (octet) payload.
12. ATM provides a defined Quality of Service (QoS), which supported different
types of traffic, including;
1_________
2. ________
3._________
13. Select the correct terms for operation at OSI layer 3:
 Data link or network layer
 Bridge or router
 Frame or packet
16. The IP Time To Live field is used to _________________________.
17 A “virtual circuit” is synonymous with:
 A datagram
 A connection
 Isochronous communications
 Connectionless communications
18. The X.25 standard defines:
 A packet assembler/disassembler protocol
 An interface to a packet-switched network
 A cell-replay approach to networking
 A proprietary approach to internetworking
19. In frame relay, if the user sends faster than the committed information rate within
the excess information rate, the network will:
 Discard the data
 Mark the data as being “Eligible for Discard”
 Delay sending the data with other packets
 Combine the data with other packets
