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
✓
Restrict the NSG rule source IP to trusted administrative networks or implement Azure Bastion for secure management.
Exposing RDP directly to the internet is a high risk; remediation involves restricting the source IP range or using Azure Bastion.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Restrict the NSG rule source IP to trusted administrative networks or implement Azure Bastion for secure management.
Why this is correct
Restricting RDP source IPs or using Azure Bastion mitigates brute-force attacks.
- ✗
Disable the Azure Key Vault service across the subscription.
Why it's wrong here
Key Vault has no direct relationship with VM RDP exposure.
- ✗
Enable Azure Active Directory Pass-Through Authentication on the VM guest OS.
Why it's wrong here
PTA applies to Azure AD hybrid identities, not local VM RDP.
- ✗
Attach an AWS IAM instance profile to the Azure Virtual Machine.
Why it's wrong here
AWS IAM profiles cannot be attached to Azure VMs.
