Question 3

You are having router issues. You are trying to forward data to the destination 172.16.46.191/26. You hook up wireshark to the router to view the traffic flow. Wireshark shows that the router is dropping the data. Why is the router dropping the data? Pg 256

Answer 3

/26 is a 255.255.255.192 mask. Which would give you a block size of 64. Do the math and 191 is a broadcast IP and will be discarded by the router by default.

Question 6

You are troubleshooting a friends network. They cannot ping their router and they do not have access to the Internet. You decide to ping their loopback and you still get no response. What is the likely issue? Pg 258

Answer 6

If you ping the loopback and receive an “unable to contact IP driver, error code 2”, you need to reinstall the TCP/IP protocol suite on that can’t computer.
