Accepted Answer

The IT architecture defines the approved network, data, interface and processing technologies, the ongoing process for researching emerging technologies, the strategy for integrating legacy systems and technologies into the application architecture, and the ongoing process for reviewing the application architecture for currency and appropriateness.

Question 2

Which of the following describes a rule of correctness for drawing a physical data flow diagram?
A) a system that works
B) a system that fulfills user requirements
C) a system that provides adequate performance (throughput and response timE.
D) a system that is adaptable to changing requirements and enhancements
E) all of these

Accepted Answer

A physical data flow diagram should represent a system that works, fulfills user requirements, provides adequate performance, and is adaptable to changing requirements and enhancements.

Question 3

The application architectural blueprint communicates which of the following design decisions?
A) The distribution of stored data across a network
B) The technology to be used to interface with other systems
C) The technology to be used to implement the user interface
D) The integration of any commercial off-the-shelf software
E) all of these

Accepted Answer

The application architectural blueprint typically encompasses all aspects of the system's design, including data distribution, interfacing technologies, user interface implementation, and integration of commercial software.

Question 4

In which application architecture do you NOT need to worry about developing for different computer architectures?
A) file server
B) distributed data client/server
C) network computing
D) distributed presentation client/server
E) distributed data and application client/server

Accepted Answer

In network computing, the focus is on using network resources and services, often abstracting away the underlying hardware architecture, so developers don't need to worry about different computer architectures.

Question 5

In which application architecture does the client PC do virtually all the actual work?
A) file server
B) distributed data client/server
C) network computing
D) distributed presentation client/server
E) distributed data and application client/server

Accepted Answer

In a file server architecture, the client PC is responsible for most of the processing work, while the server primarily provides file storage and retrieval services.
