An organization needs to route traffic from an Azure subnet through a network virtual appliance (NVA) before it reaches the internet. Which Azure feature should be used?
Answer: User Defined Route (UDR)
User Defined Routes (UDRs) override Azure's default system routes, allowing you to direct traffic to a next-hop such as an NVA.
What is the purpose of the 'effective routes' view in Azure Network Watcher?
Answer: It shows the combined routing table applied to a network interface
The effective routes view combines system routes, user-defined routes, and BGP routes to show the actual routing table used by a network interface.
Which Azure networking component operates as a stateful packet filter and can be associated with both subnets and individual network interfaces?
Answer: Network Security Group (NSG)
NSGs are stateful packet filters that contain inbound and outbound security rules and can be applied at the subnet level or directly to a network interface.
When configuring VNet peering between two virtual networks in different Azure regions, what is this configuration called?
Answer: Global VNet peering
VNet peering between virtual networks in different Azure regions is called global VNet peering, and it uses the Microsoft backbone network.
A subnet has a route table with a user-defined route pointing 0.0.0.0/0 to an NVA. What happens to traffic destined for an Azure Storage service endpoint configured on the same subnet?
Answer: Traffic goes directly to Azure Storage via the service endpoint route
Service endpoint routes have a longer prefix match than 0.0.0.0/0 and take precedence, routing storage traffic directly to the service over the Azure backbone.
What is the CIDR notation for a subnet that contains exactly 256 IP addresses?
Answer: /24
A /24 prefix leaves 8 bits for host addresses, providing 2^8 = 256 total IP addresses in the subnet.
Which Azure DNS feature allows you to use custom domain names for resources within a virtual network without deploying your own DNS servers?
Answer: Azure Private DNS zones
Azure Private DNS zones provide name resolution for resources within and across virtual networks using custom domain names without requiring custom DNS infrastructure.
