What is the smallest IP address range you can assign to an Azure subnet using CIDR notation?
- A/28
- B/30
- C/29✓
- D/24
Answer: The smallest subnet Azure supports is a /29, which contains 8 addresses. Azure reserves 5 addresses in every subnet (the network address, the default gateway, two for Azure DNS mapping and the broadcast address), so a /29 leaves 3 usable addresses. A /30 is too small to be accepted, while /28 and /24 are valid but larger.
How many IP addresses does Azure reserve in every subnet?
- A1
- B3
- C5✓
- D8
Answer: Azure reserves five addresses in each subnet: the network address, the broadcast address, and three for internal services (gateway and DNS mapping).
