HPE4-A50 Sample Questions

  1. Question 1

    Advanced

    Protect and Defend · Implement HPE Aruba Zero Trust Security

    A large financial institution is deploying a Zero Trust Security model using HPE Aruba Networking solutions. The design requires that all IoT devices connected to Aruba CX 6300 switches are automatically placed into a specific VXLAN-based overlay network without manual port configuration. The devices must be profiled by ClearPass, and the switch must download the tunneling configuration dynamically. Which mechanism should be configured on the AOS-CX switches and ClearPass to achieve this requirement?

    Answer and explanation

    Correct answer: B

    For dynamic VXLAN-based segmentation (often part of a User-Based Tunneling or UBT setup in modern AOS-CX architectures interacting with gateways), the ClearPass Policy Manager must return a Downloadable User Role (DUR) or Local User Role that specifies the gateway zone and the reserved VLAN (or VNI mapping) to direct traffic into the tunnel. This enables the 'colorless port' concept where the switch dynamically tunnels traffic based on the authenticated role.

  2. Question 2

    Intermediate

    Protect and Defend · Integrate HPE Aruba Networking solutions with ecosystem partner solutions

    You are integrating a third-party Mobile Device Management (MDM) system with ClearPass Policy Manager to enforce compliance checks for employee smartphones. The requirement is to deny network access if the device is 'Jailbroken' or 'Rooted'. After configuring the Endpoint Context Server in ClearPass, what is the immediate next step to use this data in an enforcement policy?

    Answer and explanation

    Correct answer: A

    After defining the Endpoint Context Server, you must ensure ClearPass knows how to interpret the data received. This often involves verifying the Context Server Actions (polling or webhook handling) or mapping the incoming MDM attributes (like 'device_compromised') to ClearPass dictionary attributes so they can be referenced in Role Mapping or Enforcement Policies.

  3. Question 3

    IntermediateMultiple answers

    Protect and Defend · Define PKI best practices

    A network administrator is designing a PKI solution for 802.1X authentication. The security policy mandates that all Windows corporate laptops authenticate using certificates issued by the internal Microsoft CA. The ClearPass server must validate the revocation status of these certificates in real-time. Which two configuration steps are required to meet this requirement? (Select TWO)

    Answer and explanation

    Correct answers: B, D

    Real-time revocation checking requires OCSP (Online Certificate Status Protocol). The OCSP URL must be configured in ClearPass (often within the CA certificate details in the Trust List or the Authentication Method settings) to allow it to query the CA's status responder.

    To validate client certificates, ClearPass must trust the issuing CA. This requires importing the Root and any Intermediate CA certificates into the Trust List.

  4. Question 4

    Advanced

    Analyze · Use HPE Aruba Networking solutions to log issues and monitor behavior

    You are creating a Network Analytics Engine (NAE) script on an Aruba CX switch to monitor for potential ARP spoofing attacks. The script should trigger an alert if the rate of ARP changes for a specific IP address exceeds a threshold. Which NAE specific database resource should your script monitor to detect this behavior?

    Answer and explanation

    Correct answer: B

    In the AOS-CX REST API and NAE database structure, ARP table information is typically found under the L3/Neighbors/ARP path (or similar depending on exact version, but 'Neighbors' is the key resource for ARP entries). Monitoring changes in this resource allows the script to track MAC address associations for IPs.

  5. Question 5

    Beginner

    Protect and Defend · Design and deploy Gateway IDS/IPS

    True or False: When configuring a Gateway IDS/IPS policy on an Aruba 9004 Gateway in an AOS 10 environment, you must enable 'Fail-Open' mode to ensure traffic continues to flow even if the IPS engine becomes overloaded or fails.

    Answer and explanation

    Correct answer: A

    True. In production environments where availability is critical, 'Fail-Open' is the standard best practice configuration. It ensures that if the IDS/IPS inspection engine fails or is overwhelmed, traffic is permitted to pass through without inspection rather than dropping all traffic (Fail-Close), which would cause a network outage.

  6. Question 6

    Advanced

    Protect and Defend · Implement role-based access control

    During a practical exam task, you are asked to configure a downloadable user role (DUR) on ClearPass for an Aruba CX switch. You need to ensure that the role places the user into VLAN 20 and applies a specific ACL named 'RESTRICT_HR'. Which syntax represents the correct format for the DUR content returned by ClearPass for an AOS-CX device?

    Answer and explanation

    Correct answer: A

    AOS-CX uses a structured configuration format for DURs. The content typically defines the role context and then its attributes. The correct syntax involves 'port-access role', setting the 'vlan access', and associating the policy (ACL). The syntax is distinct from the older AOS 8 style.
