Wait, is it really '/wireless'? That seems off.

I thought it would just be 'wireless' without the slash.

The function returns a substring starting from the last '/' character.

I believe it should return '/wireless' since that's the part after the last slash, but I could be wrong about how substr handles the position.

I’m a bit confused. If strrpos gives the position of the last slash, does substr start from that position or the next character?

I think the function is supposed to return the substring starting from the last slash, but I'm not entirely sure how substr works with the position returned by strrpos.

I remember practicing a similar question where we had to extract parts of a file path. I think it was about getting the last part after the last slash.

Hmm, I'm a little confused. The question mentions removing field-level access from three profiles in the sandbox, but it's not clear which ones. I'll need to double-check that before deciding on the best approach.

Hmm, I'm a little unsure about this one. The question is asking about a specific type of incentive calculation, but the answer choices don't seem to clearly match the description. I'll need to think this through more carefully.

I'm pretty sure this is about internal controls for preventing fraud, so it's probably cash advances.
