Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.)
- Destination MAC addresses will never change in a frame that goes across seven routers.
- A packet that has crossed four routers has changed the destination IP address four times.
- Every time a frame is encapsulated with a new destination MAC address, a new destination IP address is needed.
- Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another.
- Destination IP addresses in a packet header remain constant along the entire path to a target host.
