A store-and-forward switch always stores the entire frame before forwarding

A store-and-forward switch always stores the entire frame before forwarding, and checks its CRC and frame length. A cut-through switch can forward frames before receiving the destination address field, thus presenting less latency than a store-and-forward switch. Because the frame can begin to be forwarded before it is completely received, the switch may transmit a corrupt or runt frame. All forwarding methods require a Layer 2 switch to forward broadcast frames.

The adjacent interfaces are passive.

The distance of 120 exceeds 15 hops.

R2 will not accept version 1 updates from R1.

Routes are being summarized by R1 but not by R2.



Refer to the exhibit. Two routers are unable to establish an adjacency. What is the possible cause for this?
