Question 1
Computer 1 on network A, with IP address of 10.1.1.205, wants to send a packet to Computer 2, with IP address of 172.16.1.57. On which network is computer 2?
Network A
Network C
Network B
Local network
2.
Question 2
For what purpose would computer 1 send a FF:FF:FF:FF:FF broadcast ARP message to all nodes on network A?
To verify the internet connection
To obtain Computer 2 MAC address
To obtain Router Y’s MAC address
To calculate the TTL
3.
Question 3
Which layer constructs the IP datagram?
Application layer
Data layer
Network layer
Physical Layer
4.
Question 4
What information is in the payload section of the TCP segments?
The application layer data
ART Table
The MAC address of Computer 1
Handshake
5.
Question 5
When constructing the Ethernet datagram to send the packet from computer 1 to its gateway (Router Y), what information needs to be in the destination MAC address?
Router Z’s MAC address
Computer 2’s MAC address
Router Y’s MAC address
Computer 1’s MAC address
6.
Question 6
Computer 1 on Network A sends a packet to Computer 2 on Network C. What’s the last step that Router Z does after receiving the Ethernet frame?
Decrements the TTL by 1, calculates a new checksum, and makes a new IP datagram. This new IP datagram is again encapsulated on a new Ethernet frame.
Calculates a checksum and compares this checksum with the one in the Ethernet frame header
Sends back the packages to router Y for confirmation
Strips away the Ethernet frame, leaving the IP datagram. Performs a checksum calculation against the entire datagram

Question 7
Computer 1 on network A, with IP address of 10.1.1.8, wants to send a packet to Computer 2, with IP address of 172.16.1.64. If the TTL value was set to 64 at the beginning, what is the value of the TTL once it reaches its destination?
0
60
65
62

Question 8
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. Taking in consideration that computer 1 is sending a request to a web server on computer 2, listening on port 80, and the source port on computer 1 is 5000, which of the following contains the correct information for the first TCP segment of data?
Source Port: 80
Destination Port: 5000
Sequence Number: 1
Acknowledgment Number: 2
Source Port: 80
Destination Port: 5000
Sequence Number: 1
Acknowledgment Number: 1
Source Port: 5000
Destination Port: 80
Sequence Number: 1
Acknowledgment Number: 2
Source Port: 8081
Destination Port: 50
Sequence Number: 4
Acknowledgment Number: 1

Question 9
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 172.16.1.64. Which of the following has the correct IP datagram information for the fields: Version, minimum Header Length, Source IP, and Destination IP?
Version: 4
Header Length: 20
Source IP Address: 10.1.1.10
Destination IP address: 172.16.1.64
Version: 6
Header Length: 20
Source IP Address: 8a:1a:2b:3c:4d:5f
Destination IP address: 2a:2b:3c:4d:8f
Version: 5
Header Length: 16
Source IP Address: 171.1.1.1.
Destination IP address: 172.16.1.0/24.
Version: 4
Header Length: 32
Source IP Address: 10.1.1.1
Destination IP address: 172.16.1.1
