26. Frage
Refer to the exhibits.
HPE Aruba Networking ClearPass Policy Manager (CPPM) is authenticating 802.1X clients using Active Directory as the source. CPPM has a custom attribute for AD that uses AccountStatus as userAccountControl.
Which enforcement profile does CPPM apply to a client that:
Succeeds in authenticating to an active AD user account:
userAccountControl = 512
Does not succeed at authenticating as a computer
Antwort: D
Begründung:
The role mapping policy uses Evaluate all, so CPPM checks all role-mapping rules. The client has userAccountControl = 512, which matches the first AccountStatus rule and assigns role1.
The client does not authenticate as a computer, so it does not receive the built-in [Machine Authenticated] role. The enforcement policy uses First applicable, so CPPM checks the rules from top to bottom and applies the first matching rule only. Rule 1 requires role1 and [Machine Authenticated], so it does not match. Rule 2 requires role2 and [Machine Authenticated], so it does not match. Rule 3 requires only [Machine Authenticated], so it also does not match. Rule 4 requires role1, which matches. Therefore, CPPM applies profile3.
27. Frage
Refer to the exhibits.
You are setting up HPE Aruba Networking ClearPass Policy Manager (CPPM) to authenticate wireless clients with EAP-TLS and 802.1X. CPPM should assign clients to an AOS firewall role named contractors-fullaccess if the clients meet these requirements:
AD account is enabled: AccountStatus 512
Security group name is Contractors
What should you do to make these policies meet these requirements?
Antwort: B
Begründung:
The role mapping policy is configured to Evaluate all, so a client with an enabled AD account receives role1, and a client in the Contractors group receives role2. A client that meets both requirements receives both roles. The enforcement policy uses First applicable, and rule 1 already checks for both conditions: Tips:Role EQUALS role1 AND Tips:Role EQUALS role2.
Therefore, the matching logic is already correct. What is missing is the correct enforcement action. To assign an AOS firewall role, CPPM must return the appropriate RADIUS enforcement profile containing the Aruba-User-Role VSA set to contractors-fullaccess. Changing only role mapping names does not assign the firewall role. Adding a separate role2-only rule would incorrectly match Contractors users whose AD account status is not enabled.
28. Frage
Refer to the exhibit.
You have verified that AOS-CX Switch-1 has constructed an IP-to-MAC binding table in VLANs 10-19.
Now you need to enable ARP inspection for the endpoint connected to Switch-1. What must you do first to prevent traffic disruption?
Antwort: D
Begründung:
Dynamic ARP Inspection (DAI):
* ARP inspection verifies ARP packets against a trusted IP-to-MAC binding table to prevent ARP spoofing attacks.
* DHCP snooping is required to construct the IP-to-MAC binding table dynamically.
* To avoid traffic disruption, uplink ports that connect to trusted switches, DHCP servers, or routers must be explicitly configured as trusted ports for ARP inspection.
Steps to Prevent Traffic Disruption:
* Trust the Uplinks: ARP inspection must treat uplink ports as trusted to allow ARP traffic from legitimate DHCP servers and upstream switches.
* Enable DHCP Snooping: DHCP snooping must be enabled on Switch-2 to ensure consistent IP-to- MAC bindings upstream.
Why the Answer is Correct:
* Option A: Incorrect. ARP inspection on Switch-2 is important but not required first to prevent disruption on Switch-1.
* Option B: Incorrect. DHCP snooping must be enabled upstream eventually, but this alone will not stop immediate traffic disruption on Switch-1.
* Option C: Correct. Switch-1 uplinks must be trusted ARP inspection ports first to allow legitimate upstream traffic and prevent ARP disruption.
* Option D: Incorrect. Static bindings are not required if DHCP snooping is enabled, and they are manual, limiting scalability.
Conclusion:
To avoid traffic disruption, configure Switch-1 uplinks as trusted ARP inspection ports to ensure valid ARP traffic can pass upstream and downstream.
29. Frage
You need to use "Tips:Posture" conditions within an 802.1X service's enforcement policy.
Which guideline should you follow?
Antwort: D
Begründung:
When using "Tips
" conditions within an 802.1X service's enforcement policy, you should enable caching roles and posture attributes from previous sessions in the service's enforcement settings. This ensures that ClearPass retains posture information from previous authentications, which is necessary for making decisions based on the current posture state of an endpoint. By caching these attributes, ClearPass can apply appropriate enforcement actions based on the device's posture status.
30. Frage
You are configuring an HPE Aruba Networking VIA solution for a customer. The customer wants this behavior for remote clients that connect to the VPN:
* They forward internet traffic locally.
* They forward traffic destined to the data center over the VPN.
How can you configure this behavior?
Antwort: B
Begründung:
The requirement describes split tunneling. Internet-bound traffic should remain local at the remote client, while traffic destined for corporate data center networks should traverse the VPN tunnel. In Aruba VIA, this behavior is configured in the VIA Connection Profile by enabling split tunneling and defining which destination networks should be tunneled. Adding the data center networks to the tunneled networks list ensures only those corporate routes are sent through the VPN. Firewall roles control access permissions after authentication, but they are not the primary place to define the VIA client's split-tunnel routing behavior.
VPN pools assign client IP addresses, not destination routing rules. Therefore, split tunneling in the VIA Connection Profile is the correct configuration.
