DP-300 Implement a secure environment Practice Question
Which THREE of the following are required to configure Microsoft Entra authentication for an Azure SQL Managed Instance?
⚠ Common exam trap
A common mix-up: candidates confuse the 'Directory Readers' role assignment (which is required) with optional network settings like VNet isolation or public access, leading them to incorrectly select C or E as necessary steps.
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
✓
Enable the managed instance system-assigned managed identity.
Enabling the system-assigned managed identity for Azure SQL Managed Instance is required because Microsoft Entra authentication relies on this identity to authenticate the instance itself against Microsoft Entra ID. Without a managed identity, the instance cannot securely obtain tokens or perform directory lookups needed for authentication and authorization.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable the managed instance system-assigned managed identity.
Why this is correct
The managed identity is used to authenticate to Entra ID.
- ✓
Set a Microsoft Entra admin for the managed instance.
Why this is correct
An Entra admin must be configured to enable Entra authentication.
- ✗
Ensure the managed instance is deployed in a different virtual network from the clients.
Why it's wrong here
VNet placement is independent of Entra authentication.
- ✓
Grant the managed instance identity the 'Directory Readers' role in Microsoft Entra ID.
Why this is correct
This permission allows the instance to query Entra ID for user/group membership.
- ✗
Configure the managed instance to allow public network access.
Why it's wrong here
Public network access is not required; Entra auth works over private connections.
