Use the following scenario to answer the 10 questions below:
You have 3 networks (A, B, and C) and 2 routers (Y and Z).
Network A has an address space of 10.1.1.0/24 and is connected to router Y, using the interface 10.1.1.1.
Network B has an address space of 192.168.1.0/24 and is connected to Router Y, using the interface
192.168.1.254. Network B is also connected with router Z, using the interface of 192.168.1.1.
Network C has an address space of 172.16.1.0/24 and is connected to router Z, using the interface
172.16.1.1. The diagram below represents these connections and interfaces.

TTL value
Destination MAC address
Port number
3.
Question 3

Question 5
When constructing the Ethernet datagram to send the packet from Router Z to Computer 2 which is on
Network C, what information needs to be in the destination MAC address?
1 point
Computer 1’s MAC address
No MAC address is needed
Computer 2’s MAC address
Router Y’s MAC address
6.
Question 6
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?
1 point
Sends an ARP broadcast message
Increases the TTL by one
Checks the destination IP address and changes it to its own
Calculates a checksum and compares this checksum with the one in the Ethernet frame header
7.
Question 7
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?
1 point
65
63
61
8.
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?
1 point
Source Port: 5000
Destination Port: 80
Sequence Number: 1
Acknowledgment Number: 2
Source Port: 8081
Destination Port: 50
Sequence Number: 4
Acknowledgment Number: 1
