Q1. 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?
Answer: Network B
Explanation: Since Computer 1 is on network A (IP range 10.x.x.x) and Computer 2 is on network B (IP range 172.x.x.x), Computer 2 is on a different network.
Q2. Computer 1 wants to send a packet to Computer 2. Since computer 2 is not on the local network, Computer 1 checks the ARP table for the corresponding ______ that matches the gateway IP.
Answer: MAC address
Explanation: In ARP (Address Resolution Protocol), the MAC address is used to map the gateway’s IP address, allowing Computer 1 to send the packet to the gateway.
Q3. Which layer constructs the IP datagram?
Answer: Network layer
Explanation: The network layer is responsible for constructing and addressing the IP datagram, which includes the source and destination IP addresses.
Q4. What information is in the payload section of the TCP segments?
Answer: The application layer data
Explanation: The payload section of a TCP segment carries the data being transmitted, which is typically the application layer data.
Q5. 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?
Answer: Router Y’s MAC address
Explanation: Since the packet is being sent to the gateway, the destination MAC address in the Ethernet frame will be Router Y’s MAC address.
Q6. Computer 1 on Network A sends a packet to Computer 2 on Network C. What’s the first step that Router Z does after receiving the Ethernet frame?
Answer: Checks the destination IP address and changes it to its own
Explanation: When Router Z receives the Ethernet frame, it will check the destination IP address, then strip off the Ethernet frame, process the IP packet, and update the destination IP address as needed.
Q7. 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?
Answer: 0
Explanation: The TTL (Time to Live) field decreases by 1 with each hop. Once it reaches the destination, the TTL will be 0.
Q8. 1 on network C, with IP address of 172.16.1.57, wants to send a packet to Computer 2, with IP address of 192.168.1.14. 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 fourth TCP segment of data?
Answer: Source Port: 5000, Destination Port: 80, Sequence Number: 4, Acknowledgment Number: 5
Explanation: For the fourth TCP segment in the connection, the source port would be 5000, destination port would be 80 (web server), and the sequence and acknowledgment numbers would increment accordingly.
Q9. 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 172.16.1.57. Which of the following has the correct IP datagram information for the fields: Version, minimum Header Length, Source IP, and Destination IP?
Answer: Version: 4, Header Length: 20, Source IP Address: 192.168.1.121, Destination IP address: 172.16.1.57
Explanation: IPv4 has a version number of 4, and the minimum header length is 20 bytes. The source and destination IP addresses are correctly listed as Computer 1 and Computer 2.
Q10. The Cat6 cable is part of the ______ layer
Answer: Physical
Explanation: The Cat6 cable is part of the physical layer of the OSI model, as it is used to transmit data physically over the network.
