I feel like I saw customExecutionStats in a practice question, but I can't recall if it's the default mode.

I remember practicing a question like this, and I think executionStats was mentioned as a common option.

I think the default mode for explain() is queryPlanner, but I'm not completely sure.

I have a vague recollection that allPlansExecution is the default, but it could also be queryPlanner.

I've got this! The answer is C - Platform Events for the Salesforce to Legacy System direction, and Enterprise WSDL for the communication back. That matches the requirements perfectly.

Reducing makes sense to me based on what we practiced, but increasing one of them sounds plausible too. I just wish I could remember the exact wording from the materials!

Okay, I've got this. Gantt charts are great for illustrating task dependencies and showing how different tasks are related. That's definitely the best use of this tool.

I remember from my compliance training that concentration accounts can sometimes create monitoring challenges, so this description fits perfectly.
