Appian ACD101 Exam - Topic 2 Question 19 Discussion

Actual exam question for Appian's ACD101 exam

Question #: 19
Topic #: 2

You are using a local variable in an expression rule to describe the height of an applicant.

Which statement correctly describes the application of Appian best practices for naming your local variable?

Alocal!hoaa - This employs the naming convention of abbreviating 'Height of an applicant' to minimize both the typing required by developers and the length of code Appian is required to parse.

Blocal!applicantHeight - This employs the naming convention of specifically describing the value contained by the variable.

Clocal!x - This employs the naming convention of using algebraic variables for a value that may either change over time or be used by future developers for other purposes.

Show Suggested Answer

Suggested Answer: B

The best practice for naming variables in Appian is to use clear and descriptive names that convey the purpose or content of the variable. Therefore, local!applicantHeight is the best option as it precisely describes the value contained by the variable, which is the height of an applicant. This naming convention aids in readability and maintainability of the code, making it easier for developers to understand and modify the code in the future.

Wait, local!x? That’s a bit too vague, right?

C just seems confusing, why not be specific?

A is way too abbreviated, not a fan.

I’m a bit confused about option C. Using 'local!x' seems too vague, but I guess it could work in some contexts? I’m not sure if it’s best practice though.

I think I saw a similar question in our practice tests. If I recall correctly, option B was highlighted as the best practice for naming conventions.

I'm not entirely sure, but I feel like using abbreviations like in option A could lead to confusion later on. We should aim for descriptive names, right?

I remember we discussed the importance of clear variable names in our last study session. I think option B makes the most sense for clarity.

I think the best approach here is to use the most descriptive variable name possible, which would be option B. "local!applicantHeight" clearly communicates the purpose of the variable, which is important for maintainability and understanding the code.

Option A seems like it might be the right answer - "local!hoaa" to abbreviate "Height of an Applicant". That would follow the convention of minimizing typing and code length. But I'm not 100% sure.

Hmm, I'm a bit unsure about this one. I know Appian has specific naming conventions, but I can't quite remember the details. I'll have to think this through carefully.

I'm pretty confident this is option B - "local!applicantHeight". Appian best practices recommend using descriptive variable names that clearly communicate the purpose of the variable.

This seems like a straightforward configuration question. I'll need to carefully read through the requirements and think about the different options.

Appian devs who use 'local!x' must also prefer their variable names to be as mysterious as their codebase. Just sayin'.

I'm with Dallas on this one. 'local!x' is the coding equivalent of shrugging your shoulders. Let's be better than that.
