Q271.
Which of the following is not a workflow in RUP?

a.

Requirements workflow

b.

Deployment workflow

c.

Cleaning workflow

d.

Test workflow

Discuss
Answer: (c).Cleaning workflow Explanation:RUP distinguishes nine workflows, such as a requirements workflow, a test workflow, etc. Cleaning workflow is not one of the RUP workflow.
Q272.
What is the main focus of RUP's construction phase?

a.

Analyzing the problem domain

b.

Obtaining a sound architecture

c.

Developing deployable products

d.

Releasing the system to the user community

Discuss
Answer: (c).Developing deployable products Explanation:The construction phase in RUP focuses on developing deployable products, complete components are developed and thoroughly tested. User manuals are written. At the end of this phase, the first operational version of the system, the beta release, is ready.
Q273.
What is the main goal of RUP's inception phase?

a.

Resolving all major risks

b.

Clearing objectives and determining the scope of the project

c.

Developing an architecture

d.

Releasing the system to the user community

Discuss
Answer: (b).Clearing objectives and determining the scope of the project Explanation:The inception phase in RUP focuses on getting the objectives clear, what is the scope of the project, what are its boundaries, what are the acceptance criteria that will be used when the system is delivered to its customers? During this phase too, the overall cost, schedule and risks are estimated.
Q274.
What is the main goal of RUP's elaboration phase?

a.

Resolving all major risks

b.

Clearing objectives and determining the scope of the project

c.

Developing an architecture

d.

Releasing the system to the user community

Discuss
Answer: (c).Developing an architecture Explanation:The elaboration phase in RUP is mainly targeted at analyzing the problem domain, and obtaining a sound architecture. At the end of this phase, most use cases will be identified, and all major risks must be resolved.
Q275.
What is the main goal of RUP's transition phase?

a.

Resolving all major risks

b.

Clearing objectives and determining the scope of the project

c.

Developing an architecture

d.

Releasing the system to the user community and beta testing

Discuss
Answer: (d).Releasing the system to the user community and beta testing Explanation:In the transition phase, the system is released to the user community and beta tested.
Q276.
What is the main difference between maintenance and initial development of a system?

a.

The changes are being made to an existing product

b.

The system is developed from scratch

c.

The time pressure is less during maintenance

d.

The system's entropy decreases during maintenance

Discuss
Answer: (a).The changes are being made to an existing product Explanation:A considerable maintenance effort is inevitable. Each maintenance task, whether it concerns repairing an error or adapting a system to new user requirements, in principle entails all aspects of the initial development cycle. During maintenance, we also have to analyze the problem and conceive a design which is subsequently implemented and tested. The first big difference is that these changes are being made to an existing product.
Q277.
How does time pressure affect maintenance activities?

a.

Time pressure is not felt during maintenance

b.

Time pressure makes it easier to identify and repair errors

c.

Time pressure hampers thorough analysis and design step

d.

Time pressure increases the system's entropy

Discuss
Answer: (c).Time pressure hampers thorough analysis and design step Explanation:The second main difference, time pressure, has a much larger impact. Time pressure is most strongly felt when repairing errors, for then it is quite possible that certain parts of the organization have to shut down because the software is not operational. In such cases, we have to work against time to identify and repair the errors. Often one patches the code and skips a thorough analysis and design step. The structure of the system tends to suffer from such patches. The system’s entropy increases, which hampers later maintenance activities.
Q278.
How does patching the code during maintenance activities affect the system's structure?

a.

It improves the system's structure

b.

It has no effect on the system's structure

c.

It worsens the system's structure

d.

It increases the system's entropy

Discuss
Answer: (c).It worsens the system's structure Explanation:Often one patches the code and skips a thorough analysis and design step. The structure of the system tends to suffer from such patches. The system’s entropy increases, which hampers later maintenance activities.
Q279.
What happens when the system's documentation is not updated during maintenance activities?

a.

The system's documentation is updated automatically

b.

The system's entropy decreases

c.

Software and the corresponding documentation grow apart

d.

The system's structure improves

Discuss
Answer: (c).Software and the corresponding documentation grow apart Explanation:When the system's documentation is not updated during maintenance activities, the software and the corresponding documentation grow apart, which will hamper future maintenance activities. This makes it more difficult for maintainers to understand the system, and to make changes to it without introducing errors or causing other problems. This can lead to increased maintenance costs, and can make it more difficult to adapt the system to changing user requirements or to fix errors that are discovered later on.
Q280.
According to the laws of software evolution, what happens to a program that is changed over time?

a.

It becomes more structured and less complex

b.

It becomes less structured and more complex

c.

It remains the same level of complexity

d.

It becomes more efficient

Discuss
Answer: (b).It becomes less structured and more complex Explanation:The Law of increasing complexity states that a program that is changed becomes less and less structured and thus becomes more complex.
