Question 1

The function that provides the processing logic required by the human computer interaction layer is called presentation logic.

Accepted Answer

The presentation logic is responsible for taking user input from the human computer interaction layer and processing it through business logic to generate output for the user.

Question 2

A server in the server-based architecture performs application logic, data access logic, data storage, and presentation logic.

Accepted Answer

In server-based architecture, the server performs all application, data access, storage, and presentation logic.

Question 3

The languages in which the system needs to operate are documented as part of the customization requirements.

Accepted Answer

The answer of The languages in which the system needs...

Question 4

In a deployment diagram, a communication path represents a communication link between the nodes of the physical architecture, and communication paths may be stereotyped.

Accepted Answer

This statement is true. Communication paths in a deployment diagram represent communication links between physical nodes, and they may be stereotyped to indicate specific types of communication (e.g. synchronous, asynchronous, etc.).

Question 5

Assume that your network has a server and three clients, this network is an example of a four-tiered architecture.

Accepted Answer

A four-tiered architecture typically includes four layers: presentation tier, application tier, database tier, and client tier. In this scenario, there is only one server and three clients, which suggests a two-tiered or client-server architecture rather than a four-tiered architecture.

Question 6

Speed requirements, which are one kind of performance requirements, attempt to predict how many total and simultaneous users the system will need to support.

Accepted Answer

Speed requirements focus on how fast the system performs certain operations, not on how many users it can support simultaneously. That aspect is covered by scalability or capacity requirements.

Question 7

The major problem with a server-based architecture is that all data on the server must travel to the client for processing.

Accepted Answer

In a server-based architecture, the server typically processes the data and then sends the results to the client, rather than sending all data to the client for processing.

Question 8

In order to prepare computer systems for global communication, discrete multilingual systems contain separate parts that are written in multiple languages and must have each language reinstalled before it can be used.

Accepted Answer

The answer of In order to prepare computer systems for...

Question 9

Encryption and authentication requirements address virus control measures.

Accepted Answer

Encryption and authentication requirements do not directly address virus control measures. Virus control measures typically include anti-virus software, firewalls, and other security protocols.

Question 10

Capacity requirements, which are one kind of performance requirements, attempt to predict how fast the system should operate.

Accepted Answer

The answer of Capacity requirements, which are one kind of...

Question 11

Minicomputer typically costs hundreds of thousands of dollars while a mainframe costs millions of dollars.

Accepted Answer

Minicomputers are smaller and less expensive than mainframes, typically costing hundreds of thousands of dollars, whereas mainframes are larger, more powerful, and can cost millions of dollars due to their extensive processing capabilities and support for numerous users and applications.

Question 12

Maintainability and access control requirements are better met by the server-based architectures than the client-server architectures.

Accepted Answer

In server-based architectures, all the functionalities and data are centralized, making it easier to control and maintain access permissions. On the other hand, client-server architectures distribute functionalities and data between the client and server, making it harder to control and maintain access permissions. Therefore, server-based architectures are better suited for maintaining access control and maintainability requirements.

Question 13

The function that provides the logic related to the problem domain layer is called application logic.

Accepted Answer

The application logic is responsible for providing the logic related to the problem domain layer.

Question 14

Access control requirements state who can access data and what type of CRUD data access is permitted to each individual who has access to data.

Accepted Answer

Access control requirements define who can access data and specify the type of CRUD data access permitted to each individual who has access to data.

Question 15

Scalability is an important attribute in today's systems. Client-server architectures tend to be more scalable compared to the server-based architectures.

Accepted Answer

Client-server architectures can be easily scaled by adding more clients or servers to the system. This is because the load is distributed across multiple machines, making it more efficient and able to handle more traffic. Server-based architectures, on the other hand, rely on a single server to handle all requests, making it harder to scale as the load increases.

Question 16

Thin client-server architectures do not have the ability to address cultural and political requirements better than the server-based architectures.

Accepted Answer

Thin client-server architectures have the potential to address cultural and political requirements better than server-based architectures because they allow for greater customization and localization at the client end. However, the answer may also depend on the specific implementation and configuration of the architectures in question.

Question 17

System integration requirements document how the technical environment might change in the future and how the system must respond to future technical environment changes.

Accepted Answer

System integration requirements document how different systems will interact, communicate, and work together in the current environment, rather than focusing on future technical environment changes.

Question 18

"The system should be operational on a 24 / 7 basis for the users." This is an example of the availability and reliability requirements.

Accepted Answer

The statement highlights the requirement for the system to be available and reliable at all times, indicating its importance in ensuring uninterrupted service to users.

Question 19

The function that provides the processing required to query a database and other logic related to the data management layer is called presentation logic.

Accepted Answer

The function that provides the processing required to query a database and other logic related to the data management layer is called data access logic, not presentation logic. Presentation logic is concerned with how the data is displayed or presented to the user.

Question 20

Client-based systems are ill equipped to meet operational, performance, security, and cultural / political requirements.

Accepted Answer

Client-based systems rely on individual devices to run software, which can limit their ability to meet operational, performance, security, and cultural / political requirements. Centralized server-based systems may be better equipped to address these issues.
