A company wants to apply role-based access control lists (ACLs) on AOS-CX switches, which are implementing authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants to centralize configuration as much as possible. Which correctly describes your options?
Answer : A
Centralized Role Configuration on CPPM:
CPPM can assign roles to clients dynamically during authentication.
However, the actual ACL policies (e.g., firewall policies) must already exist and be referenced locally on the switch.
CPPM cannot directly configure ACL details on AOS-CX switches.
Option Analysis:
Option A: Correct. The role is defined on CPPM, but it references a policy pre-configured on the switch.
Option B: Incorrect. This does not align with Aruba's centralized role-based access control design.
Option C: Incorrect. CPPM cannot configure the ACL policies and classes directly; they must exist locally.
Option D: Incorrect. Policies can be referenced centrally but not fully configured on CPPM.
A company has HPE Aruba Networking APs running AOS-10 and managed by HPE Aruba Networking Central. The company also has AOS-CX switches. The security team wants you to capture traffic from a particular wireless client. You should capture this client's traffic over a 15-minute time period and then send the traffic to them in a PCAP file. What should you do?
Answer : B
Packet Capture in Aruba Central:
Aruba Central provides tools for remote packet captures directly from the APs.
On the 'Security' page for the AP, you can initiate a packet capture session, specifying the client device and capture duration.
The traffic is captured into a PCAP file, which can be downloaded and analyzed using tools like Wireshark.
Option Analysis:
Option A: Incorrect. While possible via CLI, Aruba Central provides a simpler method for packet captures.
Option B: Correct. Aruba Central's 'Security' page allows you to capture and export client traffic efficiently.
Option C: Incorrect. The 'Live Events' page focuses on monitoring events, not packet captures.
Option D: Incorrect. Port mirroring on the switch captures AP traffic but requires more manual configuration and does not isolate client-specific wireless traffic easily.
A company needs you to integrate HPE Aruba Networking ClearPass Policy Manager (CPPM) with HPE Aruba Networking ClearPass Device Insight (CPDI). What is one task you should do to prepare?
Answer : B
ClearPass Device Insight Integration:
To integrate ClearPass Device Insight (CPDI) with ClearPass Policy Manager (CPPM), you must enable the Insight feature in the CPPM server configuration settings.
This ensures CPPM can share and receive profiling data with CPDI for device identification.
Option Analysis:
Option A: Incorrect. Root CA certificates are not required for this integration.
Option B: Correct. Enabling Insight on CPPM is essential for the integration to function.
Option C: Incorrect. WMI, SSH, and SNMP are not part of the CPDI integration prerequisites.
Option D: Incorrect. The Data Collector token is relevant to Aruba Central, not CPDI integration.
A company wants you to create a custom device fingerprint on CPPM with rules for profiling a group of specialized devices. What is one requirement?
Answer : A
Custom Device Fingerprinting on CPPM:
To create a custom fingerprint, you first need to connect a known device of that type to the network.
CPPM will discover the device in its Endpoints Repository, allowing you to analyze its attributes (e.g., MAC OUI, DHCP options) and create custom profiling rules.
Option Analysis:
Option A: Correct. Discovering a known device in the Endpoints Repository is a prerequisite for creating accurate custom fingerprint rules.
Option B: Incorrect. CPDI integration is not required for custom fingerprints on CPPM.
Option C: Incorrect. XML rules are not pre-defined; they are created dynamically based on observed attributes.
Option D: Incorrect. The 'Automatically download Endpoint Profiler Fingerprints' setting is unrelated to custom profiling.
Refer to the exhibit:
The exhibit shows the TACACS+ enforcement profile that HPE Aruba Networking ClearPass Policy Manager (CPPM) assigns to a manager. When this manager logs into an AOS-CX switch, what does the switch do?
Answer : A
TACACS+ Enforcement Profile:
The profile specifies a Service Attribute under Aruba:Common with:
Name: Aruba-Admin-Role
Value: operators
AOS-CX Role Mapping:
On Aruba AOS-CX switches, the Aruba-Admin-Role attribute maps the authenticated user to predefined roles:
operators: Operator-level privileges (read-only access, limited commands).
administrators: Full administrator privileges.
Other roles like auditors may exist based on configuration.
Analysis:
The value operators explicitly maps the user to operator-level privileges, granting read-only access to the AOS-CX switch.
Since the Aruba-Admin-Role is correctly set and recognized, the switch assigns the appropriate role without errors.
Option Breakdown:
Option A: Correct. The switch assigns operator-level privileges based on the Aruba-Admin-Role value.
Option B: Incorrect. Administrator-level privileges require the role value to be administrators.
Option C: Incorrect. The manager is successfully authenticated and authorized; there is no error.
Option D: Incorrect. There is no reference to an auditor role in the configuration shown.
Conclusion:
The operators value in the TACACS+ enforcement profile ensures that the manager is assigned operator-level privileges on the AOS-CX switch.
