Show answer
Any private IP address range (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 or other RFC 1918 ranges)- Can a subnet in a VNet span multiple Azure regions?
Show answer
No, a subnet must reside entirely within a single region- What is the minimum subnet prefix size allowed in Azure?
Show answer
/29 (provides 8 addresses, 5 of which are reserved by the system)- How many virtual networks can a single subscription have by default?
Show answer
50 virtual networks (can be increased by submitting a quota increase request)- What are Azure Virtual Network service endpoints?
Show answer
Direct connections that provide secure, private access to Azure services without routing traffic over the public internet- Does intra-region VNet peering incur data transfer charges?
Show answer
