Answer:
The statements which are true are;
- A user-defined data type can include other user-defined data types
- A user-defined data type is defined using a class
- A user-defined data type can include a list
Explanation:
A user-defined data type (UDT) is a datatype that is defined and derived by the use of the datatypes which preexist including existing user-defined datatypes and the built-in datatypes
It is therefore true that a user-defined data type can include other user-defined data types
A class is a user-defined data type that contains both its member data and member functions, that can be used when an instance of the class is first created
Therefore, a user-defined data type is defined using a class
In a user-defined data type, a variable has actual data within it which can include an array or list
Therefore a user-defined data type can include a list.
Answer:
False
Explanation:
BugTraq is a high volume, full disclosure mailing list for the detailed discussion and announcement of computer security vulnerabilities, not US-CERT

Answer: Probability/impact risk matrix
Explanation: Probability/impact risk matrix is type of matrix that defines the probability as well as impact that depicts whether the risk is low ,high or moderate.
Impact matrix is sort of tool which helps in conversion of any plan into a action. Probability matrix help in defining the chances in defining the risk.The positioning of the impact value of risk is plotted on the vertical axis and performance value on the horizontal axis.
Thus probability/impact matrix is the correct tool for the problem mentioned in the question.
