Options A and B? What is this, amateur hour? Everyone knows you gotta use those indexed fields to handle big data, am I right?

Definitely, queries A and B won't cut it for handling large data volumes. We need to leverage those indexed fields.

I agree with you, Emile. Option C uses a bind variable which can handle large data volumes efficiently.

Ooh, tough choice, but I think I'll go with B and D. Indexing on the external ID fields seems like a good way to speed things up.

I'm going with C and D. Using an IN clause with a list variable and filtering on the indexed IsDeleted field should be pretty efficient.

Haha, I bet the exam writers are trying to trick us with those other options. Who would use a query with a null check on Name? That's just asking for trouble!

Option D looks good to me. Filtering by Name and IsDeleted is a smart way to avoid the soft-deleted records and optimize the query for large data volumes.
