AZ-104: Microsoft Azure Administrator Full Course - Private Zone - Scenario II

The video tutorial explains the use of DNS private zones across multiple virtual networks, focusing on a scenario with two virtual networks: one for registration and one for resolution. It describes how DNS records are managed and how DNS query behavior changes, including forward and reverse queries. The concept of split horizon functionality is introduced, where reverse DNS queries are scoped to the same virtual network. The tutorial concludes with a preview of a DNS name resolution lab demonstration.

What is the primary purpose of using DNS private zones across multiple virtual networks?

• To improve network speed

• To increase the number of virtual networks

• To share a common DNS zone for resolution and registration

• To enable public access to virtual machines

In the described setup, what happens when a DNS query is made from a VM in the resolution network for a VM in the registration network?

• It receives an error message

• It receives a public IP address

• It receives a DNS response with the private IP of the VM

• It receives no response

What is the expected result of a reverse DNS query from a VM in the resolution network for a VM in the registration network?

• It receives a timeout error

• It receives an NX domain

• It receives the private IP of the VM

• It receives the FQDN of the VM

What is the outcome of a reverse DNS query from a VM in the resolution network for another VM in the same network?

• It receives the FQDN of the VM

• It receives the private IP of the VM

• It receives an NX domain

• It receives a successful response

What functionality is described by the term 'split horizon' in the context of DNS queries?

• It increases DNS query speed

• It enables public DNS queries

• It restricts reverse DNS queries to the same virtual network

• It allows DNS queries to be resolved across different networks
