Refer to the exhibit. Workstation A sends an IP packet to workstation B. Which two statements describe the encapsulation of the packet as it passes through the network? (Choose two.)
- The source Layer 3 address is changed when it is received at each router.
- The destination Layer 2 address of the frame does not change as it is forwarded.
- The Layer 2 header is stripped from the frame when it is received by each router.
- The Layer 3 header is stripped from the packet when it is received at each router.
- The Layer 2 header of the frame is reassembled when it is forwarded by each router.

Explanation: When a router receives a frame on an interface, it strips the Layer 2 frame header information from the frame. It checks the routing table to determine which interface to use to send the packet to its destination. Once the interface is known, the packet is encapsulated with a new frame header containing different source and destination MAC addresses. |
