Wait, are we sure about B? Can you really loop through values like that?

E looks wrong too, keySet() gives IDs, not Account records.

D seems off, you can't iterate a Map directly like that.

C is not valid, you can't use an index with a Map.

A and B are definitely valid!

I practiced a similar question, and I believe option B should work because it lets us loop through the values directly.

I'm a bit unsure about option C; I remember we can't use a traditional for loop like that with a Map, right?

I think option A is definitely valid since we're iterating over the keys of the map.

I feel like option D is incorrect, but I'm not completely sure why. Can we iterate over a map like that?

The AP failover priority seems like the most straightforward answer. I'll go with that unless I spot something else that seems more likely.

Hmm, this looks like a tricky one. I'll need to think through the possible causes carefully.
