Asynchronous Transfer Mode Quiz

What is Asynchronous Transfer Mode (ATM)?

• A circuit-switched networking technology

• A packet-switching technology

• A hybrid technology combining circuit and packet switching

• A cell-based switching technology

ATM uses fixed-length cells of how many bytes?

• 48 bytes

• 53 bytes

• 64 bytes

• 128 bytes

How many bytes are allocated for the payload in an ATM cell?

• 53 bytes

• 48 bytes

• 5 bytes

• 56 bytes

How many bytes are allocated for the header in an ATM cell?

• 5 bytes

• 48 bytes

• 53 bytes

• 4 bytes

What is the primary benefit of ATM's fixed cell size?

• It reduces overhead.

• It simplifies hardware implementation.

• It helps in managing different types of traffic like voice, video, and data.

• It allows dynamic allocation of bandwidth.

Which layer of the OSI model does ATM primarily operate in?

• Data Link Layer

• Network Layer

• Physical Layer

• Transport Layer

What type of switching does ATM use?

• Circuit Switching

• Packet Switching

• Cell Switching

• Message Switching

Which of the following is a major application of ATM?

• Email transmission

• Voice and video transmission in real-time

• Web browsing

• File transfer

Which layer in ATM is responsible for cell multiplexing and switching?

• ATM Adaptation Layer (AAL)

• ATM Layer

• Physical Layer

• Transport Layer

Which of the following describes ATM Adaptation Layer (AAL)?

• It defines how ATM cells are transmitted on the physical medium.

• It provides mechanisms to adapt higher-layer protocols for ATM.

• It is responsible for multiplexing and demultiplexing cells.

• It handles error correction for ATM cells.
