D sounds right. You definitely need an input method for N1 and N2.

Wait, are you sure about B? What if the inputs aren't integers?

A makes sense too. Without a print method, nothing shows up.

I feel like the sum should show up in the TextView after the button is clicked, so I'm leaning towards option B as the right answer.

I think we discussed needing to set up input methods for user data, so option D could be relevant too. But I'm not completely confident.

I'm not entirely sure, but I feel like we did a similar question where we had to convert inputs to integers first. That makes me lean towards option C.

I remember something about how the result should display in a TextView when a button is clicked, so I think option B might be correct.

Hmm, this looks like a tricky one. I'll need to think through the socket module syntax carefully.

I'm a bit confused by this question. There are a lot of business and technical concepts being thrown around. I'm not entirely sure what "SOA services orchestration and reusability" means in practical terms. I think I'd need to do some more research on SOA and business architecture before I could confidently answer this. Maybe I'll make a note to review those topics before the exam.

Ugh, I can never remember which component does what. I'll guess VPN filter just to be safe, but I feel unsure about that.

This one seems pretty straightforward. I'm pretty confident the answer is A - Daily Scrum, Sprint Review, and Sprint Retrospective.

Okay, I think I've got this. I just need to plug the numbers into the right formula and I should be able to determine the correct ratio.

Wait, how am I supposed to use this calculator if I don't have a way to input the numbers? Option D is the only logical choice here.

Option B is the way to go. The sum result will show up in the TextView as long as the button click event is properly implemented.

Haha, this code is missing the input method to enter the values of N1 and N2. Option D is the way to go, unless you want to do mental math every time!
