Discuss at least two security advantages of a host running virtualization.
What will be an ideal response?
The latest security updates can be downloaded and run in a virtual machine to determine compatibility. A snapshot of a state of a virtual machine can be saved for later use. Testing the existing security configuration, known as security control testing, can be performed using a simulated network environment on a computer using multiple virtual machines. Virtual machines can promote security segregation and isolation. A virtual machine can be used to test for potential malware.

Which of the following statements is true?
``` public class TestA { public static void main(String[] args) { int x = 2; int y = 20 int counter = 0; for (int j = y % x; j < 100; j += (y / x)) { counter++; } } } public class TestB { public static void main(String[] args) { int counter = 0; for (int j = 10; j > 0; --j) { ++counter; } } } ``` a. The value of counter will be different at the end of each for loop for each class. b. The value of j will be the same for each loop for all iterations c. Both (a) and (b) are true. d. Neither (a) nor (b) is true.

Is this server a stateful server? If so, what kind of state information (global or session) does it maintain?
Using the three-tier software architecture presented in this chapter, design and implement a client-server suite for the following protocol (it is not a well-known service): Each client sends to the server a name. The server accumulates the names received from successive clients (by appending each, with a linefeed (‘
’), to a static string). Upon receiving a name, the server sends the names that it has collected to the client. The figure below illustrates the sequence diagram of a session of the protocol.
