Select the correct statement(s) regarding Frame Relay (FR). a. FR is a connection-oriented standard that operates at the OSI layers 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

d. all of the statements are correct

Explanation:

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.
