Appian ACD201 Exam - Topic 2 Question 18 Discussion

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? (Choose two.)
B) Create the two POST APIs as asynchronous subprocesses. and D) Add a terminate process node to the end of the process.
A) Ensure that the entire process is activity-chained so that the person entering the transaction knows when the process is completed.
C) Create the two POST APIs as synchronous subprocesses.

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.

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

Show Suggested Answer Hide 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.

I’m a bit confused about the activity-chaining part. Does that really help with process memory, or is it more about user experience?

I remember a similar question where we discussed the benefits of synchronous vs asynchronous calls. I feel like asynchronous might be the way to go here.

I think we should consider using asynchronous subprocesses for the POST APIs to improve memory, but I'm not entirely sure if that's the best approach.
