As a frame leaves a Layer 3 device, the Layer 2 encapsulation information is changed from what it was
when it entered the device. For what two reasons can this happen? (Choose two.)
A. The data is moving from 10BASE-TX to 100BASE-TX.
B. The W AN encapsulation type has changed.
C. The data format has changed from analog to digital.
D. The source and destination hosts are in the same subnet.
E. The source and destination MAC addresses have changed.

Which two statements are true regarding EIGRP? (Choose two.)
A. Passive routes are in the process of being calculated by DUAL.
B. EIGRP supports VLSM, route summarization, and routing update authentication.
C. EIGRP exchanges full routing table information with neighboring routers with every update.
D. If the feasible successor has a higher advertised distance than the successor route, it becomes the
E. A query process is used to discover a replacement for a failed route if a feasible successor is not identif from the current routing information.
