az-800 Practice Question 1898
Exam: az-800
Domain: Implement and manage an on-premises and hybrid networking infrastructure
Topic: Implement on-premises and hybrid name resolution
Difficulty: medium
Your company has recently migrated some of its services to Azure but still needs to maintain access to on-premises resources via DNS. You want to ensure that these resources can be accessed using a consistent domain name without exposing them to the public internet. What solution should you implement to achieve this?
Answer Options
A
Implement DNS forwarding to an external DNS server
B
Configure Split-brain DNS with separate internal and external DNS zones
C
Deploy Azure Private DNS to manage private DNS zones
D
Use standard public DNS zones for both internal and external access
Correct Answer
C: Deploy Azure Private DNS to manage private DNS zones
Explanation
Azure Private DNS provides a way to manage private DNS zones within your virtual network, allowing you to control how names are resolved within your network without exposing them to the public internet. Split-brain DNS and DNS forwarding would not provide the isolation and control needed for private resource access.
