Question

Frame Relay is a _________ layer protocol, generally used for ____.

a. Data link, WANs
b. Data link, LANs
c. Physical, WANs
d. Physical, LANs

Answer 1

Frame Relay is a Data link layer protocol utilized for WANs, enabling multiple virtual circuits to efficiently share the same physical network infrastructure.

Step-by-step explanation:

Frame Relay is a Data link layer protocol, generally used for WANs (Wide Area Networks). This protocol operates at the Data Link layer of the OSI model, which is responsible for data transfer between nodes on a network and provides mechanisms for error correction and flow control. Frame Relay is optimized for high performance and operates on a packet-switched network, which allows multiple virtual circuits to share the same physical network infrastructure, making efficient use of bandwidth.
