- Which of the following characteristics below are associated with a UDP socket? Check one or more that apply.MCQ: Which of the following statement is TRUE? InetAddress is used by other network classes like Socket and ServerSocket to identify hosts. There are public InetAddress() constructors. Using InetAddress, arbitrary addresses may be created. InetAddress class represents as Port address.Assume that our LastPass web server is configured to use port 7777 rather than the default HTTP port. Also assume that two users on the website, X and Y, are using their home computers to visit the web server at the same time. Are all of the requests from X’s computerand Y’s computer being sent to the same socket at the web server? If yes, how does the webserver distinguish the requests from different clients? If not, do the different sockets both have port 7777? Why? Assume that the LastPass web server uses persistent connections.
- The following program sets up a single client/server connection. When the client connects, the server reads any incoming data as text and prints it out one line at a time. If the server receives the string “shutdown”, then it closes the socket and exits. Download this program Download this program into GCC and run the code. Then update your code to allow for the server to manage concurrent connections on the same port. Use IP address 127.0.0.1.

Question 2 options: True FalseRouter5 is in rom mode, and there is an enable password on it which we don't know. Bring it back to boot in normally, set new enable password of 'cisco' and restore its configuration. IF the original configuration is restored, the router should be able to ping the others without any further configuration. If the interface (on Router5) are down (it will be red) after you restore, bring the interface up with 'no shutdown command' Wait until you see the messege "from loading to FULL, LOADING done" BEFORE TRYING TO TEST PING 0x2102 (boot normally) (default)0x2120 (rom mode)0x2142 (ignore nvram content) This is all ONE question, please answer full question.
