You have a VNet that is currently using Azure-provided DNS. You need to change the VNet to use a custom DNS server. What is the effect of this change on existing VMs in the VNet?

Existing VMs immediately start using the new DNS server without any action.

Existing VMs will continue using Azure-provided DNS until they are deleted and recreated.

Existing VMs must be restarted or have their network interfaces updated to pick up the new DNS settings.

Existing VMs will use both Azure-provided DNS and the custom DNS server simultaneously.

You have a VNet with VMs that need to resolve both Azure-provided names (e.g., 'vm1.internal.cloudapp.net') and names in a private DNS zone 'corp.local'. You set the VNet DNS server to a custom DNS server. What must the custom DNS server do to ensure both resolutions work?

Use Azure-provided DNS for all queries

Host a copy of the private zone locally

Forward queries for 'corp.local' to Azure DNS (168.63.129.16) and resolve other names itself

Forward all queries to Azure DNS

A company has a public DNS zone 'contoso.com' in Azure. They have a web app with a custom domain 'app.contoso.com' that is behind Azure Front Door. They want to ensure that internet clients can resolve 'app.contoso.com' to the Front Door endpoint. What should they create in the public zone?

An NS record delegating 'app' to Front Door's name servers.

A TXT record with the Front Door verification code.

A CNAME record pointing to the Front Door endpoint hostname (e.g., 'contoso.azurefd.net').

An A record with the Front Door endpoint's IP address.

You need to enable DNS resolution between an on-premises network and Azure VNets. You plan to use Azure DNS Private Resolver. What is the primary function of the Azure DNS Private Resolver?

It hosts public DNS zones for internet-facing domains.

It blocks DNS queries from the internet to Azure VNets.

It provides a private IP address for every VM in a VNet.

It forwards DNS queries between on-premises networks and Azure VNets.

You need to configure a VNet to use a custom DNS server. Where do you specify the custom DNS server address for the VNet?

In the VM's network interface (NIC) settings.

In the Azure DNS zone's settings.

In the virtual network gateway's settings.

In the VNet's DNS settings, under 'Custom DNS'.
