Longer multiple choice questions (3 points each) Coding Question - Fibonacci sequence You are to write a method named "Fibo" that takes as input an integer n, and returns the nth number in the Fibonacci sequence. If Fibo (n) denotes the nth number in the Fibonacci sequence, then recall for n > 2, Fibo (n) = Fibo (n-1) + Fibo (n-2), and Fibo (1) = 1 and Fibo (2) = 1. You are to assume that the user is always going to enter an input greater than 2. For example Fibo (4) = 3. Use the 7 following questions to "write" your code. Pay close attention to how your answers group together with each other. 26. Line 1 (A) public static int Fibo (int n) { (B) public static void main(String[] args) { (C) public static int Fibo () { (D) public static void Fibo (Double input) { (E) public static void Fibo (int n) {

29. Recall that some IP addresses are reserved for private use (e.g., in a home, small business, or portions of a larger network). An example are addresses 10.0.0.0 to 10.255.255.255, used for private networks. All IP packets have a source IP address and a destination IP address. Then a Network Address Translation (NAT) is used so that a) Packets passing from private network to public network have their destination addresses modified. b) Typically packets passing from the private network to the public network have their source addresses modified while packets passing from the public network back to the private network have their destination addresses modified. x c) Packets passing from public network to private network have their source addresses modified. d) Typically packets exchanged between private and public networks have both their source and destination addresses unchanged. e) All of the above
