Question 6

During the _____ phase of the systems development life cycle (SDLC),a team assesses how a system is working and takes steps to keep the system up and running.
A)planning
B)implementation 
C)maintenance
D)design

Accepted Answer

The maintenance phase is focused on keeping the system operational and addressing any issues that arise. During this phase, the team monitors the system to ensure it is working properly, performs updates and upgrades as needed, and provides support to users.

Question 10

In the extreme programming environment,_____ programming allows programmers to detect and correct programming mistakes as they go,which is faster than correcting them after an entire program has been written.
A)procedural
B)pair 
C)sequential
D)parallel

Accepted Answer

Pair programming is a practice in extreme programming where two programmers work together on one computer. One programmer writes the code while the other reviews every line of code. This allows mistakes to be detected and corrected as they are made, resulting in faster correction and a better-quality end product.

Question 11

Accepted Answer

The answer of Explain feasibility and its importance in designing...

Question 12

The fundamental principle behind _____ is that the self-contained blocks of codes can be reused in a variety of different applications,allowing new business processes to be created from a pool of existing services.
A)rapid prototyping
B)joint application design
C)service-oriented architecture
D)computer-aided systems engineering

Accepted Answer

The principle described is the core concept of service-oriented architecture (SOA), which allows businesses to create new processes by reusing existing services. Rapid prototyping refers to the quick creation of prototypes, joint application design is a collaborative approach to designing software, and computer-aided systems engineering is a methodology for designing and developing systems.

Question 17

The_____ is an incremental development process that has less emphasis on team coding and more emphasis on limiting a project's scope.
A)The V-shaped model
B)The joint application design approach
C)Rapid prototyping
D)Agile methodology

Accepted Answer

The Agile methodology is an incremental development process that focuses on collaboration, flexibility, and customer satisfaction. It emphasizes iterative, adaptive planning, evolutionary development, and delivery. It also places less emphasis on team coding and more emphasis on limiting a project's scope by breaking it down into smaller, more manageable portions. The other options listed do not address this specific aspect of development approach.
