Atm Frame Relay — Test 1

Correct Answer: B. B. Asynchronous time division multiplexing
Explanation: ATM uses a constant data stream consisting of transmission cells to transmit information in a fixed division of time. The packet size remains fixed.

Correct Answer: B. B. 3
Explanation: The three layers are physical layer, ATM layer and application adoption layer. The physical layer corresponds to the physical layer, ATM layer corresponds to the data link layer and the AAL layer corresponds to the network layer of the OSI model.

Correct Answer: D. D. Networks covering any range
Explanation: ATM is a connection oriented network for cell relay which can be implemented for networks covering any area. It uses Time Division Multiplexing and supports voice, video and data communications.

Correct Answer: B. B. 48 bytes
Explanation: An ATM field contains a header and a payload. The header is of 5 bytes and the payload is of 48 bytes. The size of the header remains fixed.

Correct Answer: A. A. Virtual circuit networks
Explanation: ATM and frame relay are transmission modes in which information is transferred through electric circuit layer as packets. ATM has fixed packet size and frame relay has variable packet size.

Correct Answer: B. B. Loss of cell delineation
Explanation: The ATM has helped bring about the merger of computer and telecommunication networks. The ATM Forum, an organization that specifies standards for ATM implementation, has also provided a framework for network management. The subject of ATM is full of acronyms. Therefore LCD in ATM networks stands for ‘Loss of Cell Delineation’.

Correct Answer: C. C. . when the connection is established for long periods of time and not switched between sessions, a permanent virtual circuit (pvc) is established. advertisement
Explanation: The VP- VC can be established on a per session basis or on a permanent basis between a pair of end stations that carry large volumes of traffic. In the former ease, the circuit is established as and when needed and torn down after the session is over. This is called the switched virtual circuit (SVC). When the connection is established for long periods of time and not switched between sessions, a permanent virtual circuit (PVC) is established.

Correct Answer: A. A. Service provider
Explanation: There are two markets for ATM switches using ATM technology, public and private. A public network is the network that is established by the service provider. A private network is primarily a campus network.

Correct Answer: B. B. False
Explanation: The broadband network and the narrowband Integrated Services Digital Network (ISDN) are multimedia networks that provide integrated analog and digital services over the same network. The broadband network can transport very high data rate signals.

Correct Answer: C. C. WAN
Explanation: The broadband network can transport very high data rate signals. It is a multimedia transportation networking. The computer network uses the facilities of the telecommunication network fur transportation over WAN. Thus Broadband network management consists of managing the WAN using ATM technology.
