Discuss WGU Scripting And Programming Foundations (D278) Exam Topic 3 Question 9

A software developer determines the mathematical operations that a calculator program should support When two waterfall approach phases are involved?

ADesign and Testing

BImplementation and testing

CDesign and implementation

DAnalysis and design

Suggested Answer: D

Here's the typical flow of the Waterfall software development model:

Analysis:This phase focuses on defining the problem and gathering detailed requirements for the software. Understanding the specific mathematical operations to support is a key part of this phase.

Design:Designers turn the requirements from the analysis phase into a concrete blueprint for the software. This includes architectural and detailed design decisions covering how those mathematical operations will be implemented.

Implementation:Developers take the design and translate it into working code, writing the modules and functions to perform the calculations.

Testing:Testers verify the software to ensure it meets the requirements, including testing how the implemented calculator functions handle different operations.

Maintenance:Ongoing support after deployment to address bugs and introduce potential changes or enhancements.

Why the other options are less accurate:

A . Design and Testing:While testing validates the calculator's functions, thedeterminationof the required operations happens earlier in the process.

B . Implementation and Testing:Implementation builds the calculator, but the specifications and choice of operations happen before coding starts.

C . Design and Implementation:Though closely linked, the design phase finalizes the operation choicesbeforeimplementation begins.

B) Implementation and testing seems off. Testing comes after coding, right?

Novella 1 month ago

I feel A) Design and Testing is too late for defining operations.

Loren 1 month ago

True, but analysis is part of the design phase too.

Nelida 2 months ago

But what about D) Analysis and design? You need to analyze first!

Bette 2 months ago

I agree, C) is logical. You need a solid design before coding.

Cassie 2 months ago

I think it's C) Design and implementation. Makes sense to define first.

Vesta 2 months ago

True, but design shapes everything. C) is the best choice overall.

Jarvis 2 months ago

I feel B) is also valid. Testing is crucial after implementation.

Marshall 2 months ago

But without implementation, how do you test? C) is still better.

Lorrie 3 months ago

I'm leaning towards D) Analysis and design. You need to analyze requirements first.

Christoper 3 months ago

I agree, C) is logical. You need a solid design first.

Rolland 3 months ago

I think it's C) Design and implementation. Makes sense to define before coding.

Diane 3 months ago

What about B) Implementation and testing? That seems important too!

Kindra 3 months ago

I agree with C! You can't implement without a solid design first.

Celestina 4 months ago

Wait, is it really just those two phases? Sounds too simple.

Yuriko 5 months ago

I thought it was A) Design and Testing. Seems logical too!

Nickole 5 months ago

Definitely C) Design and implementation. That's how it usually goes!

Jeff 6 months ago

I keep mixing up the phases, but D) Analysis and design sounds like it could be part of the initial steps in the waterfall approach.

Della 6 months ago

I feel like I’ve seen a similar question before, and it was about B) Implementation and testing. That seems relevant too.

Dante 6 months ago

I'm not entirely sure, but I remember something about A) Design and Testing being important in ensuring the program meets requirements.

Chaya 6 months ago

I think the answer might be C) Design and implementation since those phases are closely related in the waterfall model.
