I have a vague memory of option D, but I don't think PHP has a __toJson() method for objects.

Option C seems off to me; I don't recall using the new Json() syntax in PHP.

Wait, I'm a little confused. How do we determine the number of APs needed? Is it just a simple calculation based on the client count, or are there other factors to consider? I want to make sure I understand this properly before selecting an answer.

Hmm, I'm not entirely sure about this one. I think I need to double-check the GoldenGate documentation to make sure I fully understand the differences between the available options. I want to make sure I select the right approach for detecting update and delete conflicts.

This is a tricky one, but I'm pretty sure the answer is A. The other options seem to be describing physical characteristics, not leadership types. I'll mark A and move on.

Aha, I see what they're getting at. If an iRule references an event that doesn't occur, that could cause issues with the client's connection. I'll go with that option.

I wonder if option D involves turning the value into a Transformer first, and then converting it to JSON. Probably best to keep it simple with json_encode().

If I see 'Json' with a capital 'J', I automatically assume it's not the standard PHP function. json_encode() all the way!

Converting the value to an object and then calling a custom __toJson() method? That's just weird. json_encode() is the way to go.

Creating a new Json object and then converting it to a string? That seems overly complicated. I'll stick with the simple json_encode() method.
