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

The video tutorial discusses the importance of private DNS zones in Azure, using scenarios to illustrate their application. It explains how to set up a virtual network with Azure resources, ensuring private name resolution via DNS zones. The tutorial covers automatic DNS registration for VMs, creating private zones, and handling DNS queries and responses. It emphasizes the role of internal DNS for resolving internal resources within Azure.

What is the primary purpose of private DNS zones in Azure?

• To ensure name resolution is private within a virtual network

• To provide backup for DNS records

• To enhance the speed of internet access

• To make resources publicly accessible

In the given scenario, what types of resources are mentioned as being part of the virtual network?

• Web servers and storage accounts

• Virtual machines and SQL databases

• Load balancers and firewalls

• Blob storage and CDN

Why is it important for Azure to automatically register VMs into the DNS zone?

• To improve the performance of virtual machines

• To reduce the cost of DNS management

• To facilitate automatic updates of DNS records

• To ensure VMs are accessible from the internet

What happens when a DNS query is made from VM1 to resolve VM2 in the private zone?

• It receives a DNS response with the private IP of VM2

• It fails to resolve the query

• It receives a public IP of VM2

• It redirects to a different DNS server

What is the expected outcome of a reverse DNS query for the private IP of VM1?

• It provides the FQDN of VM1

• It returns the public IP of VM1

• It redirects to a public DNS server

• It results in a DNS error
