4 Top of FormWhich two statements accurately describe the result of entering the command BRT(config-if)# frame-relay map ip 10.1.10.1 35 on a router? (Choose two.)

The remote router updates the Frame Relay map table with DLCI 35 to reach the 10.1.10.0 network.

A Layer 2 address is statically mapped to a Layer 3 address.

Router BRT uses DLCI 35 to forward data to 10.1.10.1.
