az-800 Practice Question 1897
Exam: az-800
Domain: Implement and manage an on-premises and hybrid networking infrastructure
Topic: Implement on-premises and hybrid name resolution
Difficulty: medium
In a hybrid environment, you need to ensure that internal on-premises resources can be accessed by external clients using a specific domain name. Which of the following should you configure to achieve this while maintaining separate internal and external DNS zones?
Answer Options
A
Configure Azure Private DNS zone for both internal and external clients
B
Set up Split-brain DNS with separate internal and external DNS zones
C
Enable DNS forwarding to an external DNS server for all queries
D
Use a single DNS zone with both internal and external records
Correct Answer
B: Set up Split-brain DNS with separate internal and external DNS zones
Explanation
Split-brain DNS allows different DNS zones to be used based on the source of the DNS query. This is ideal for hybrid environments where internal and external clients need to resolve names differently. Forwarding would only direct traffic to an external DNS server, and Azure Private DNS would not provide the split functionality required in this scenario.
