Question 1

Nathan is an expert on all of the different kinds of process description tools. So, when his colleagues have questions, they know where to turn.
-One of the firm's trainee analysts is working on a financial process that will continue to print vendor payments until it reaches the end of the file. Which of the following processes will Nathan suggest the analyst to use?

Accepted Answer

The process of printing vendor payments until the end of the file involves a repetitive task. Therefore, the process description tool best suited for this scenario is iteration. Iteration is a looping process that repeats a set of instructions until a certain condition is met. In this case, the instructions are to print vendor payments and the condition to stop is reaching the end of the file. Therefore, Nathan will suggest the use of iteration for this particular process.

Accepted Answer

The answer of The major benefit of _____ is that...

Question 10

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-Data flow diagram (DFD) component that represents one or more data items

Accepted Answer

The component that represents one or more data items in a Data flow diagram (DFD) is called a data flow.

Question 11

A _____ is a graphical representation of the conditions, actions, and rules found in a decision table.

Accepted Answer

A decision tree is a graphical representation of the conditions, actions, and rules found in a decision table. A decision board, decision element, and decision point are not commonly used terms in the context of decision tables.

Question 12

The disadvantage of the four-model approach is that ____.

Accepted Answer

The four-model approach requires additional time and cost to develop a logical and physical model of the current system, which can be a disadvantage. This step may not always be necessary and can delay the development process.

Question 13

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-Shows how a system transforms input data into useful information

Accepted Answer

Data flow diagrams are used to illustrate how input data moves through a system and is transformed into useful information.

Answer: H
 A logical model shows how a system functions and processes data, without getting into the specifics of how it is physically implemented.

Note: Other choices may be involved in the process of analyzing and designing systems, but the given phrase specifically refers to the transformation of input data into useful information, which is best represented by a data flow diagram (DFD) or a logical model.

Question 14

The analysts at Techno InfoSystems are considering the four-model approach to system development for a new client.
-If they make use of the four-model approach, which of the following is a likely outcome?

Accepted Answer

The four-model approach involves the development of four different models, which will increase the time taken to develop the system as compared to using a single model approach.

Answer: B
 The four-model approach involves developing a logical and physical model of the current system, which will result in a better understanding of the current system and reduce the costs needed to develop the new system.

Answer: C
 The four-model approach involves developing multiple models, which will provide a clear picture of the current system functions before modifications are made. Therefore, this statement is incorrect.

Answer: D
 The requirements of a new information system may or may not be different from the current information system, and this statement is not directly related to the four-model approach.

Question 15

The analysts at Techno InfoSystems are considering the four-model approach to system development for a new client.
-Which of the following is a benefit if they use the four-model approach?

Accepted Answer

The four-model approach involves creating a current system model, a logical system model, a physical system model, and a design specification model. The benefit of creating a current system model is that it provides a clear picture of the system's functions before any modifications or improvements are made. Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately reflect the benefits of using the four-model approach.

Question 16

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-Ensures that the input and output data flows of the parent DFD are maintained on the child DFD

Accepted Answer

Balancing is the technique used in DFD that ensures that the input and output data flows of the parent DFD are maintained on the child DFD.

Question 17

The analysts at Techno InfoSystems are considering the four-model approach to system development for a new client.
-Which of the following provides a report of all data flows and data stores that use a particular data element?

Accepted Answer

Data dictionaries provide a detailed description of all data elements used in the system, including their definition, format, and relationship to other data elements. They also include information on all data flows and data stores that use a particular data element. Data types, databases, and data warehouses do not provide this level of detail on data flows and stores.

Question 18

The analysts at Techno InfoSystems are considering the four-model approach to system development for a new client.
-When data flow diagrams (DFDs) are drawn, which of the following conventions should be followed?

Accepted Answer

The answer of The analysts at Techno InfoSystems are considering...

Question 19

Many analysts follow _____, which means that they develop a physical model of the current system, a logical model of the current system, a logical model of the new system, and a physical model of the new system.

Accepted Answer

The four-model approach involves developing a physical and logical model of the current system and the proposed new system. This approach is commonly used by analysts during the system development life cycle to ensure that the new system meets the requirements of the current system and the needs of the stakeholders. The other choices, such as the Zachman Framework and Gane and Sarson symbol, are specific methodologies or techniques used in system analysis and design, but do not directly relate to the four-model approach.

Question 20

Nathan is an expert on all of the different kinds of process description tools. So, when his colleagues have questions, they know where to turn.
-Another of the firm's analysts is unable to figure out what is wrong with some structured English he has been using to describe the processing logic. Nathan walks over and spots the problem in an instant. Which of the following can Nathan identify as the problem?

Accepted Answer

Nathan is an expert on process description tools, and in structured English, a sequence, selection, or iteration structure must be used to describe processing logic. Nathan spotted the issue instantly, indicating that the problem was with the structure of the English rather than its formatting or vocabulary. The indentation of structured English is a matter of preference and does not affect its functionality. Similarly, the use of structured English as shorthand for code is a common practice that is not necessarily problematic.
