Appian ACD201 Exam - Topic 4 Question 10 Discussion

Actual exam question for Appian's ACD201 exam

Question #: 10
Topic #: 4

You're creating a point-of-sale (POS) system for a customer which can associate the items in a transaction to a customer based on a membership number. The item stock table and the customer sales record are hosted elsewhere and need to be written to via POST APIs from an Appian process model. This all occurs within a transaction process model that you're creating.

Which two steps should you perform to design your process model to improve process memory? (Select two.)

BCreate the two POST APIs as asynchronous subprocesses.

CCreate the two POST APIs as synchronous subprocesses.

DAdd a terminate process node to the end of the process.

AEnsure that the entire process is activity-chained so that the person entering the transaction knows when the process is completed.

Show Suggested Answer

Suggested Answer: B, D

Creating the POST API calls as asynchronous subprocesses allows them to run independently, reducing memory usage in the main process.

Adding a terminate process node at the end ensures the process completes and releases memory as soon as its work is finished.

Optimizing the data structures used in the process model could be another way to improve performance.

Haha, I bet the customer will love it if the POS system crashes every time they try to make a purchase!

Implementing a batching mechanism to send multiple requests at once could also help.

I think caching the API responses would be a good way to improve process memory.

I feel like there's something about clearing unused variables or data after they're no longer needed, but I’m not confident if that’s one of the steps we should choose.

I practiced a similar question where we had to optimize a process model, and I think using sub-processes could help manage memory better, but I can't recall the specifics.

I remember something about minimizing the number of API calls to improve efficiency, so maybe batching requests could be one of the steps?

I think one step might involve using local variables to store data temporarily instead of relying on global variables, but I'm not entirely sure.

I've done a few POS integrations before. Caching data and managing transactions will be important for this one.

I'm a bit confused about the requirements for the POST APIs. I'll need to make sure I understand the integration points fully.

Okay, process memory is key here. I'll need to think about how to minimize data storage and reuse results where possible.

Hmm, this sounds like a complex integration challenge. I'll need to carefully plan out the data flows and error handling.
