HP Exam HPE6-A84 Topic 4 Question 27 Discussion

Actual exam question for HP's HPE6-A84 exam

Question #: 27
Topic #: 4

You are setting up Aruba ClearPass Policy Manager (CPPM) to enforce EAP-TLS authentication with Active Directory as the authentication source. The company wants to prevent users with disabled accounts from connecting even if those users still have valid certificates.

As the first part of meeting these criteria, what should you do to enable CPPM to determine where accounts are enabled in AD or not?

AAdd an Endpoint Context Server to the domain controller with actions for querying the domain controller for account status.

BEnable OCSP in the EAP-TLS authentication method settings and configure an OCSP override to the domain controller FQDN.

CAdd a custom attribute for userAccountControl to the filters in the AD authentication source.

DInstall a Microsoft Active Directory extension in Aruba ClearPass Guest and set up an HTTP authentication source that points to that extension.

Show Suggested Answer

Suggested Answer: C

According to the ClearPass Policy Manager User Guide1, userAccountControl is a custom attribute in Active Directory that contains a set of flags that define the properties and behavior of user accounts. One of these flags is ACCOUNTDISABLE, which indicates whether the account is disabled or not. By adding this attribute to the filters in the AD authentication source, CPPM can retrieve this attribute for each user and use it as a condition in the enforcement policies to prevent users with disabled accounts from connecting even if they have valid certificates. Therefore, option C is the correct answer.

I'm a big fan of B. OCSP can give you that extra layer of security and visibility into user account status. Plus, it's a built-in feature of EAP-TLS, so it should be pretty straightforward to configure.

Barbra: That could work too, but I still think OCSP is a strong choice for this scenario.

I'm not sure, I think we should also consider adding a custom attribute for userAccountControl to the filters in the AD authentication source.

Yeah, I agree. It's a built-in feature of EAP-TLS, so it should be easy to set up.

I think B is a good option. OCSP can help us check user account status.

B looks like a clever solution to me. Querying the domain controller directly for account status could be tricky, and a custom AD extension feels like overkill. OCSP is the way to go!

Haha, D sounds like something a consultant would try to sell you. 'Oh, you need this custom extension to make it work? That'll be an extra $5,000 please.' I'm going with C - keep it simple!

C seems like the most straightforward option to me. Why overcomplicate things with OCSP or a custom extension when we can just add the userAccountControl attribute to the AD authentication source filters?
