AI-200 Event Driven Integration Practice Question
You are designing a disaster recovery strategy for an Azure Event Hubs namespace. You configure Geo-Disaster Recovery pairing between a primary region (East US) and a secondary region (West US). During a disaster drill, you trigger a failover. What happens to the DNS alias pointing to the Event Hubs namespace?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The alias is automatically updated to point to the secondary namespace, enabling client reconnection without changing connection strings.
When Geo-DR failover is invoked, the DNS alias is repointed from the primary namespace to the secondary namespace automatically, ensuring client connection strings referencing the alias continue working.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The primary namespace automatically becomes the replica of the secondary namespace without breaking the pair.
Why it's wrong here
Failover breaks the pairing; you must re-establish pairing in reverse after failover.
- ✓
The alias is automatically updated to point to the secondary namespace, enabling client reconnection without changing connection strings.
Why this is correct
The Geo-DR alias abstracts the underlying namespace endpoints, ensuring seamless failover redirection.
- ✗
The alias enters a Read-Only state for 24 hours while DNS propagation finishes globally.
Why it's wrong here
DNS propagation for Event Hubs alias failover completes rapidly (typically within minutes).
- ✗
The alias is permanently deleted and clients must be hardcoded with the secondary namespace connection string.
Why it's wrong here
The purpose of the alias is to avoid hardcoding new connection strings during failover.
