- Application layer
- Network layer
- Data layer
45. What information is in the data payload of the Ethernet frame?
- IP datagram
- network interface
- ART message
- Handshake
46. When constructing the Ethernet datagram to send the packet from Router Y to Router Z, what information needs to be in the destination MAC address?
- Computer 2’s MAC address
- Router Y’s MAC address
- Computer 1’s MAC address
- Router Z’s MAC address
47. Computer 1 on Network A sends a packet to Computer 2 on Network C. What's the second step that Router Z does after receiving the Ethernet frame?
- Sends an ARP broadcast message
- Sends back the packages to router Y for confirmation
- Calculates a checksum and compares this checksum with the one in the Ethernet frame header
- Strips away the Ethernet frame, leaving the IP datagram. Performs a checksum calculation against the entire datagram
48. Computer 1 on network A, with IP address of 10.1.1.10, wants to send a packet to Computer 2, with IP address of 192.168.1.14. If the TTL value was set to 64 at the beginning, what is the value of the TTL once it reaches its destination?
- 0
- 61
- 65
- 63
49. Computer 1 on network B, with IP address of 192.168.1.121, wants to send a packet to Computer 2, with IP address of 10.1.1.8.
