I'm studying for my Network+ Exam. I'm going through some practice questions, and this one has uber-stomped me in the brain. I've been going through my textbook too, and can't find a concrete answer, so I'm turning here for help.
Here it goes:
Jeff, an administrator, has just finished installing a new switch and connected two servers with IPs of 192.168.105.20 and .30. The servers are able to communicate with each other, but are unable to reach the Internet. Jeff sees the following information in the switch configuration: interface VLAN 105 IP address 192.168.105.5 255.255.255.0 Jeff is able to ping the router at 192.168.105.1 from the switch. Which of the following is the MOST likely cause of the problem? Select one:
a. Jeff used a crossover cable to connect the switch to the gateway. b. The server is missing default-gateway information. c. A routing loop has occurred. d. The subnet mask is incorrect.
I know the right answer, but I can't put together why. Would someone be so kind as to explain?
