A company uses Microsoft Entra ID. The security team needs to block all sign-in attempts from a list of known malicious IP addresses. They also want to block sign-ins that originate from anonymous proxy services. Which Microsoft Entra capability should they configure to meet these requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Conditional Access
Conditional Access can use named locations to block sign-ins from specific IP ranges and also block access from anonymous IP addresses using the 'Anonymous IP' location condition.
B
Distractor review
Identity Protection
Identity Protection detects risky sign-ins based on risk signals but cannot directly block sign-ins from a static list of malicious IP addresses.
C
Distractor review
Privileged Identity Management
Privileged Identity Management provides just-in-time privileged access and role activation, not IP-based blocking.
D
Distractor review
Access Reviews
Access Reviews are used for reviewing and certifying user access to resources, not for blocking sign-in attempts based on IP address.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.

FAQ
Questions learners often ask
What does this SC-900 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: Conditional Access — Conditional Access policies can define named locations, which include trusted or untrusted IP address ranges. The administrator can create a policy that blocks access from specified IP addresses and from locations marked as 'Anonymous IP addresses'. This meets the requirement to block malicious IPs and anonymous proxies. Identity Protection can detect risky sign-ins but does not directly allow blocking specific static IP lists. Privileged Identity Management and Access Reviews are unrelated to IP-based blocking.
