Best practice to prevent robot crashes such as out of memory

[amodsinghal]

This is a question in the Mock exam. The middle two choices appear incorrect. Choice “A-Add Clear Collection…” appears to be reasonable as a best practice, but I think that answer was marked wrong. That leaves choice “D-After every transaction…” Yes, it will work to prevent crashes, but it appears to be a very expensive way to achieve this, because of the added overhead for each transaction. What is the best practice? Thanks in advance for clarifying.

I was also going through the practice recently.

Since the question is about “repetitive process and out of memory” , best way to do it is isolate the work flows. so the answer is B.

Hi Kayobot,

Can you elaborate on your answer?
The screenshot of this “Isolated” option doesn’t indicate anything relates to robot crash or out of memory. Sounds more like a good way to do “Error handling”.

Thank you!

Its is defined in the UiPath docs as the best practice to do so. Please see below

So the Answer is B

This is very interesting! Thanks a lot for sharing!
Seems like another thread has more discussion on the “isolated”.
