possible. Which range should you use?
Given the typical subnet mask constraints, /8 (option B) is the largest block you can assign to a single subnet.
Probably B, since 10.0.0.0/8 covers more addresses than the other private ranges.
I think it’s gotta be B. The 10.0.0.0/8 range is definitely the biggest private IP block listed here, so it gives you the largest subnet possible if you ignore any platform limits. Plus, A is clearly invalid since 0.0.0.0/0 covers everything and isn’t a subnet range, just a default route. C and D are smaller blocks, so they don’t make sense for the “largest” requirement. So B makes the most sense for max size.
B/D? B has the biggest range, but some clouds limit subnet size to /16, which matches D. Without explicit limits, B seems right, but D fits real-world subnet max sizes better.
B vs D? B definitely gives a bigger range with its /8 mask compared to D’s /16. Even if there are platform limits, the question doesn’t mention any, so technically B covers the most IPs. A is obviously invalid since it’s the entire internet space, and C falls between B and D but still smaller than B. So I’d go with B for the largest possible subnet range.
Maybe D, since 192.168.0.0/16 is a standard private range and some platforms limit subnet sizes to /16 or smaller; A is definitely invalid as it covers all IPs, and B might be too large for a single subnet.
The question asks for the largest subnet range, and B (10.0.0.0/8) clearly covers the most addresses among private ranges. So B makes the most sense here.
Not C, because 172.16.0.0/12 is smaller than 10.0.0.0/8. So D is out too since 192.168.0.0/16 is even smaller. B is the biggest private range, so it fits best here.
B tbh, 10.0.0.0/8 is definitely the largest private address range you can use for a subnet in GCP. Even if GCP has some limits on subnet sizes, the question doesn’t say otherwise, so you go for the biggest valid CIDR block. The /12 or /16 options are smaller by design, and /0 isn’t a valid subnet range anyway. So, B just makes the most sense here as it maximizes the subnet size within private IP space rules.
B/D? 10.0.0.0/8 definitely gives you the biggest subnet range, but 192.168.0.0/16 is also pretty large and more common for private networks. A and C are smaller or invalid here.
B’s 10.0.0.0/8 makes the biggest subnet, right?
