A Kubernetes node is allocated a /26 CIDR block (64 unique IPs) for its

address space.

If every pod on this node has exactly two containers in it, how many pods can

this address space support on this node?

Show Suggested Answer Hide Answer
Suggested Answer: E

A Kubernetes node is allocated a /26 CIDR block (64 unique IPs) for its address space. This means that the node can assign up to 64 IP addresses to its resources, such as pods and containers. If every pod on this node has exactly two containers in it, then each pod will need two IP addresses, one for each container. Therefore, the node can support up to 32 pods, since 64 / 2 = 32. The other options are incorrect because they either exceed the available IP addresses or do not account for the number of containers per pod. Reference:

I thought it would be more than that, but I guess not.

A /26 block gives 64 IPs, so 32 pods max with 2 containers each.

I'm a bit confused about the options. Are we supposed to consider the IPs used by services too, or just the pods?

This question seems familiar; I practiced something similar where we calculated pod limits based on IP allocation. I hope I got it right!

I think we might need to divide the total IPs by the number of containers per pod, which is 2. So, could it be 32 pods?

I remember that a /26 CIDR block gives us 64 IPs, but I'm not sure how many pods we can actually run with two containers each.

Hmm, I'm not sure about this one. I know CIDR blocks and pods, but the interaction between them is tripping me up. I'll have to think it through step-by-step.

I've got this! The key is that each pod has 2 containers, so the total number of pods is half the number of IPs in the CIDR block. The answer must be 32.

Wait, I'm a bit confused. Does the question mean 32 pods per namespace, or 32 pods total? I need to make sure I understand the requirements.

Okay, let's see. A /26 CIDR block means 64 unique IPs, and each pod has 2 containers. I think I can figure this out.

Ah, I see what they're trying to do with the 'service routing' option, but that's not really relevant to the question. The answer is definitely 64 pods.

The correct answer is B) 64. The /26 CIDR block provides 64 unique IP addresses, and since each pod has exactly two containers, the address space can support 64 pods.
