1.A team of programmers is involved in reviewing a proposed design for a new utility class. After some discussion, they realize that the current design allows other classes to access methods in the utility class that should be accessible only to methods within the utility class itself.What design issue has the team discovered?（）A.Tight couplingB.Low cohesionC.High cohesionD.Loose couplingE.Weak encapsulationF.Strong encapsulation

2.A company that makes Computer Assisted Design (CAD) software has, within its application, some utility classes that are used to perform 3D rendering tasks. The company‘s chief scientist has just improved the performance of one of the utility classes‘ key rendering algorithms, and has assigned a programmer to replace the old algorithm with the new algorithm. When the programmer begins researching the utility classes, she is happy to discover that the algorithm to be replaced exists in only one class. The programmer reviews that class‘s API, and replaces the old algorithm with the new algorithm, being careful that her changes adhere strictly to the class‘s API. Once testing has begun, the programmer discovers that other classes that use the class she changed are no longer working properly.What design flaw is most likely the cause of these new bugs?（）A.InheritanceB.Tight couplingC.Low cohesionD.High cohesionE.Loose couplingF.Object immutability

3.Which of the following is NOT a security feature relating to user accounts？（）A、Some commands can be password protected requiring logged in customers to re-enter their password.B、A user account can be disabled automatically， after a specified number of invalid login attempts.C、An account can have multiple valid passwords at the same time， any of which can be used to access the account.D、The password policy feature can allow the system to require passwords to include a minimum number of numeric characters.E、Logged in customers can be logged off of the system after a specified period of inactivity.

4.A team of programmers is reviewing a proposed API for a new utility class. After some discussion,they realize that they can reduce the number of methods in the API without losing any functionality.If they implement the new design, which two OO principles will they be promoting?（）A.Looser couplingB.Tighter couplingC.Lower cohesionD.Higher cohesionE.Weaker encapsulationF.Stronger encapsulation
