Show Suggested Answer

Suggested Answer: C

Subnets are the foundational building blocks used to deploy cloud resources in your public cloud VPC. They are bound to a single zone and cannot span multiple zones or regions, which helps with security, reduces latency, and improves availability. Create multiple VPCs and subnets easily by using the suggested prefix ranges and preconfigured network security policies or design and define your own address prefixes and custom security policies. CIDR blocks 161.26/16 and 166.8/14 are both reserved and routed into every subnet. Read about our service endpoints available for IBM Cloud VPC. The default quota limit for the number of subnets that can be created within a VPC is 15.

I thought it was 25 too, but I guess it's more.

It's 200 subnets, not 25!

I honestly can’t recall the exact number, but I remember it being less than 30. I hope it’s not 12!

I’m leaning towards 15 subnets as the answer. It seems like a common limit I’ve seen in other resources.

I practiced a question like this, and I feel like 64 subnets was mentioned. Maybe that’s for a different service?

I think the default limit is 25 subnets, but I’m not completely sure. I remember something about it being a higher number.

Okay, let me think this through step-by-step. The question is asking about the default quota, so it's likely one of the more common or standard limits. I'll go with C, 64, since that seems like a reasonable default.
