Question 1

When drawing the tree, systems analysts do not have to identify:
A) all outcomes.
B) all actions.
C) the order.
D) all conditions.

Accepted Answer

A

Question 2

In order to use structured English, which convention is not advisable?
A) Express all logic in terms of sequential structures, decision structures, case structures, or iterations.
B) Blank a line and indent blocks of statements to show their hierarchy.
C) Use and capitalize accepted keywords such as IF, THEN.
D) Be careful when using "and" and "or."

Accepted Answer

Blank lines and indentation are not part of structured English.

Question 3

In order to determine the human information requirements using a decision analysis strategy, what must the systems analyst determine?
A) necessary data
B) objectives
C) information
D) data structure

Accepted Answer

To determine the human information requirements using a decision analysis strategy, the systems analyst must determine the objectives of the system. This involves identifying the goals and desired outcomes of the system, as well as determining the information needed to achieve those objectives. While necessary data, information, and data structure are all important considerations, they are secondary to determining the objectives of the system.

Question 4

Which of the following is not a problem when creating decision tables?
A) impossible situations
B) too many conditions
C) redundancy
D) contradictions

Accepted Answer

Having too many conditions can be a problem when creating decision tables because it can lead to confusion and make it more difficult to accurately analyze the data. However, impossible situations, redundancy, and contradictions are all problems that should be avoided when creating decision tables.

Question 5

Unlike the decision tree used in management science, what doesn't the analyst's tree contain?
A) decisions
B) conditions
C) outcomes
D) actions

Accepted Answer

The answer of Unlike the decision tree used in management...

Question 6

When creating process specifications, what needs to be done for manual tasks?
A) Create well-defined procedures for employees performing the tasks.
B) Replace them with automated processes.
C) Outline the decisions using a decision tree.
D) Nothing, they are not part of processing specifications.

Accepted Answer

For manual tasks, it is important to create well-defined procedures for employees performing the tasks to ensure consistency and accuracy. This can help to minimize errors and reduce the need for rework. Option B is not always feasible or cost-effective, and option C may not be relevant for all manual tasks. Option D is incorrect, as manual tasks can be an important part of processing specifications.

Question 7

Which of the following is not one of the main problems that can occur in developing decision tables?
A) incompleteness
B) impossible situations
C) contradictions
D) repetition

Accepted Answer

Repetition is not one of the main problems that can occur in developing decision tables. The main problems are incompleteness (where some combinations of conditions and actions are not accounted for), impossible situations (where no combination of conditions can result in a valid action), and contradictions (where some combinations of conditions cannot coexist).

Question 8

Process logic may be represented as:
A) structured English.
B) a decision table.
C) a decision tree.
D) a formula.
E) All of the above.

Accepted Answer

Process logic can be represented in various ways, based on the complexity and type of the process. Therefore, all the given options can be used to represent process logic in a different way. 
- Structured English provides written statements to describe the sequence of actions in a process. 
- A decision table is used when there are multiple conditions that determine the outcome of a process. 
- A decision tree presents the logic of a process in a tree-like structure, where each node represents a decision condition. 
- A formula computes a value based on given inputs, which can be used to define some logic in a process.

Thus, all of the above options could be appropriate choices to represent process logic, based on the requirement and context.

Question 9

Which of the following is not a business rule format?
A) business conditions and actions
B) user ethics
C) logical inferences
D) processing sequences

Accepted Answer

Business rule formats include business conditions and actions, logical inferences, and processing sequences. User ethics is not a business rule format but may be a consideration in determining business rules.

Question 10

Which of the following is not one of the three basic constructs used to code computer programs?
A) sequence
B) selection
C) iteration
D) computation

Accepted Answer

Computation is not one of the three basic constructs used to code computer programs. The three basic constructs are sequence, selection, and iteration. These constructs form the foundation for all computer programs.

Question 11

Which is not one of three main advantages of a decision tree over a decision table?
A) more correct as a communication tool
B) sequential structure of decision tree branches
C) conditions and actions of decision trees are found on some branches
D) more readily understood

Accepted Answer

Communication tool correctness is not one of the main advantages of a decision tree over a decision table. The three main advantages are the sequential structure of decision tree branches, the presence of conditions and actions on some branches, and the fact that decision trees are more readily understood.

Question 12

A goal of producing process specifications is to:
A) reduce process interactions.
B) build technical specifications for a specific computer language.
C) validate the system design, including data flow diagrams and the data dictionary.
D) design computer input and output processes.

Accepted Answer

The goal of producing process specifications is to validate the system design, including data flow diagrams and the data dictionary. This involves documenting how the system processes information, how data is transformed, and how it is stored. It is not about reducing process interactions, building technical specifications for a specific computer language, or designing computer input and output processes.

Question 13

When iteration is indicated for an element or a group of elements in the data dictionary:
A) a simple sequence of structured English statements is all that is necessary.
B) an IF..THEN...ELSE structured must be present in the structured English statements.
C) DO WHILE, DO UNTIL, or PERFORM UNTIL structured English statements must be included.
D) a decision table must be used to depict the logic.

Accepted Answer

When iteration is indicated for an element or a group of elements in the data dictionary, DO WHILE, DO UNTIL, or PERFORM UNTIL structured English statements must be included to depict the logic of the iteration. These statements allow the program to repeat a set of actions until a certain condition is met. Therefore, option C is the best choice.

Question 14

In order to build decision tables, what does the analyst not need to do?
A) Eliminate any impossible situations.
B) Simplify the table as much as possible.
C) Determine the minimum size of the table.
D) Eliminate inconsistencies.

Accepted Answer

The analyst does not need to determine the minimum size of the table; instead, they focus on eliminating impossible situations, simplifying the table, and eliminating inconsistencies to ensure clarity and accuracy.

Question 15

In a decision table, contradictions occur when:
A) an important condition is omitted.
B) when the situation cannot occur because there are two or more conditions that cannot occur at the same time.
C) identical sets of alternatives require the same action.
D) rules suggest different actions but satisfy the same conditions.

Accepted Answer

Contradictions in a decision table occur when rules suggest different actions but satisfy the same conditions, leading to conflicting outcomes.

Question 16

Which is the correct choice?
A) Use structured English when not every condition is relevant to every action.
B) Use decision tables when communication to end users is important.
C) Use decision trees when the sequence of conditions and actions is critical.
D) Use decision tables when there are many repetitious actions.

Accepted Answer

Decision trees are best when the sequence of conditions and actions is critical. They allow for easy visualization and understanding of complex decision-making processes. Structured English and decision tables can be used in certain contexts, but they do not prioritize the sequence of conditions and actions in the same way as decision trees.

Question 17

Primitive process specifications are not produced for:
A) processes that use decision trees.
B) processes for which prewritten code already exists.
C) processes that involve complex editing.
D) All of the above.

Accepted Answer

Primitive process specifications are only produced for processes that require new code to be written. Processes that use decision trees already have a predefined structure, and processes for which prewritten code already exists do not require new code to be written.

Question 18

Which is structured English not based on?
A) instructions organized into nested and grouped procedures
B) simple English statements
C) unstructured logic
D) add, multiply, move, and so on

Accepted Answer

Structured English is based on instructions organized into nested and grouped procedures, simple English statements, and specific commands such as add, multiply, move, and so on. Unstructured logic, however, is not part of structured English.

Question 19

When selection is indicated for elements in the data dictionary:
A) a simple sequence of structured English statements is all that is necessary.
B) an IF...THEN...ELSE structure must be present in the structured English statements.
C) DO WHILE, DO UNTIL, or PERFORM UNTIL structured English statements must be included.
D) a decision tree must be used to depict the logic.

Accepted Answer

An IF...THEN...ELSE structure is necessary to indicate selection in structured English statements, as it allows for decision-making based on conditions.

Question 20

Which of the following is not a business rule?
A) logical inferences
B) mathematical and functional derivations
C) programming language IF statements
D) definitions of business terms

Accepted Answer

Programming language IF statements are part of code logic, not business rules. Business rules are guidelines or constraints that govern business operations and decision-making.
