I think the answer to this is C.email
Answer:
FALSE
Explanation:
Because C1 and C2 implement the same interface, they both implement whichIsIt. The variable c is known as a polymorphic variable, meaning that it can change from being an C1 to a C2. So, the message c.whichIsIt( ); may invoke C1's whichIsIt or C2's whichIsIt. This can only be known at runtime.
Answer:
Extended authentication
Explanation:
Xauth = Extended authentication
An extended authentication can cause security to be increased because it requires the user to enter a username and password. These details would then be authenticated at the internal database of the controller. This extension is an ipsec extension which would enable VPN users to enter a username and password. These details would be required of the user while trying to connect and they would be checked against the login details registered by such a user.
For Arduinos, C++ wrappers around C are used. The goal is to hide the details with setting up and using the AVR, therefore, it's a pretty simple program.
Answer: C++
