I thought it would be more, but yeah, 32 makes sense.

Definitely 32, that's how CIDR works!

Totally agree, 32 pods sounds right!

Each pod has 2 containers, so 64 IPs means 32 pods.

I’m leaning towards 32 pods since each pod has two containers, but I’m worried I might be overthinking it.

I practiced a similar question where we had to calculate IPs for services, but this one feels a bit different. I hope I remember the right formula!

I think we might need to divide the total IPs by the number of containers per pod. So, could it be 32 pods?

I remember that a /26 CIDR block gives us 64 IPs, but I'm not sure how that translates to pods with two containers each.

This looks straightforward enough. The `set` will only contain unique elements, and the `count_if` function will count the number of even elements in the `set`. I'm pretty confident the answer is C, 7.

Ah, I've seen questions like this before. I think the key is to understand how oxygen can interact with the metal in the boiler to cause different types of corrosion. I'll work through that step-by-step.

Okay, I think the key here is using the product search index instead of directly querying the database. That should make the process more efficient and scalable. I'll go with option A.

I've got this one! Based on what I know about Krumholz's work, I'm pretty confident the answer is B - transactive planning. That model aligns with his emphasis on engaging the community and incorporating their knowledge and perspectives into the planning process.
