Please answer the following questions asking for protocols we’ve encountered thus far. When stating the protocol, use ONLY the acronyms that describe them (e.g. “UDP”). No answer should repeat: a. I’m a host that just attached to a public network. I obtain an IP automatically via: _______?(Which protocol?) b. I’m an application wishing to establish a reliable connection with a server via port 80.Therefore, I open a connection-oriented session using: _______ ?(Which protocol?) c. I want to reach a web server host at www.google.com, so I then obtain its IP addressusing _______ ?(Which protocol?) d. Once I connect, I---the application---pull/retrieve the web page using _________?(Which protocol?) e. Whoa, I’m the server! You tried to reach a PORT number that actually doesn’t exist!Therefore I convey my error and reply back by using ________ ?(Which protocol?) f. Hold it right there, cowboy, I’m a router!
