On the network shown in the figure, host A logs in to router A through Telnet and obtains the configuration file of router B through FTP on the remote CLI. How many TCP connections exist on router A?
I feel like it might be four connections, considering the initial Telnet and then the FTP control and data connections, but I could be overthinking it.
I've got it! The Telnet connection from Host A to Router A is one TCP connection. The FTP connection from Host A to Router B is another TCP connection. That's 2 TCP connections on Router A.
Okay, let me think this through. The first statement says no assumptions are made about the distribution, the second says the parameters don't relate to the sample, and the third says the sample and distribution have no parameters in common. I think I've got a handle on this, but I'll double-check my understanding.
I bet the guy who wrote this question was sitting in a router lab, sipping on a cup of coffee, thinking 'Let's see if these candidates can handle this one!'
This question is a piece of cake! The host A has a Telnet connection to router A, and then an FTP connection to router B. That's 2 TCP connections, so the answer is D) 2.
