Not sure about the transient keyword, does it really help that much?

Wait, can you really avoid heap limits with SOQL for loops?

I practiced a similar question where querying related objects in a collection helped manage heap size. That might be a good option here too.

I think the transient keyword is useful, but I can't recall if it applies to collections in triggers.

I'm not entirely sure, but I feel like setting collections to null after use might also be a good practice to avoid heap limits.

I remember studying the heap limit errors, and I think using SOQL for loops could help reduce memory usage.

This seems like a straightforward question about best practices for managing the Valid To date for Knowledge articles. I think I know the answer, but I'll double-check the options to be sure.

This seems pretty straightforward. I'd go with option C - using PowerShell to deploy the additional stores should be the most efficient approach.

Hmm, this seems like a tricky one. I'll need to carefully review the details about the LTM device configuration and the specific issue with the HTTPS sessions.

I think deploying HA pairs in clustering mode is an advanced setup we went over. It might be option D, but I feel like there's more nuance to it.
