Answer:
D. BGP
Explanation:
In order to exchange routing information with another AS (Autonomous Systems) only, exterior routers use an exterior routing protocol, like BGP (Border Gateway Protocol) or EGP (Exterior Routing Protocol).
BGP is an application-layer protocol in the TCP/IP suite, that uses a well-known TCP port (179) in order to deliver information reliably.
It is important to note that in order to exchange routing data within his own AS, the router uses an interior routing protocol, like OSPF.

Answer:
Explanation:
The program in question would create a new Scanner Object which asks the user for the Username first. It would then save this input into a temporary variable and compare it to the actual username in the database. Since the username is not case sensitive, we would use the toLowerCase() method on both the input and the database username so that they match even if the letters are not the same case structure. If both usernames match then we would move on to ask the user for the Password and compare it with the database password for that user. Since this one is case sensitive we would compare as is. Finally, if both Username and Password match we would print "Hello World" otherwise we would print "Login Failed."
