Select the correct statement(s) regarding Frame Relay (FR). a. FR is a connection-oriented standard that operates at the OSI lay
ers 1 and 2 b. FR packets are variable length, therefore Packet delays can be unpredictable c. FR was principally designed for "bursty" digital network traffic d. all of the statements are correct
Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI reference model. i.e Layers 1 and 2 They are designed to cope with bursty traffic. Frame relay is also a form of data networking based on packet switching in which the packets are variable in length and experience packet delays.
Based on the above definition the correct statement is option d as all of the statements define in the other option correctly defines the function of frame relay.
