HP HPE7-A02 Dumps Questions Answers

On Aruba Mobility Controllers, dataplane captures can include wireless frames encapsulated inside GRE (for example, ERM / remote mirroring or tunneled 802.11 data). If Wireshark does not have GRE dissection enabled, these packets may appear as generic IP/UDP payloads, and the inner traffic (client frames) will not decode correctly.

MC dataplane is exactly where GRE-encapsulated user traffic is likely to appear. Enabling GRE in Wireshark allows you to see and decode the inner payload (802.11/Ethernet/IP).

MC control plane traffic is generally not GRE encapsulated data traffic.

For gateways, captures exported as ERM over UDP often require different decoding (e.g., ARUBA_ERM, not generic GRE).

Thus, the most appropriate case to ensure GRE is enabled is when the capture came from the MC dataplane → Option D.

1. Understanding CPDI Risk Score and Posture Analysis

The Risk Score in ClearPass Device Insight (CPDI) is a numerical value representing the overall risk level associated with a device. It considers factors such as:

Posture Assessment: The device's compliance with health policies (e.g., OS updates, antivirus status).

Security Analysis: Vulnerabilities detected on the device, such as known exploits or weak configurations.

A Risk Score of 90 indicates a high-risk device, suggesting that the posture is unhealthy and vulnerabilities have been detected.

2. Analysis of Each Option

A. The posture is unknown, and CPDI has detected exactly four vulnerabilities on the device:

Incorrect:

The posture cannot be "unknown" because posture assessment is enabled in the settings.

CPDI does not explicitly indicate the exact number of vulnerabilities directly through the Risk Score.

B. The posture is healthy, but CPDI has detected multiple vulnerabilities on the device:

Incorrect:

A Risk Score of 90 is too high for a "healthy" posture. A healthy posture would typically result in a lower Risk Score.

C. The posture is unhealthy, and CPDI has also detected at least one vulnerability on the device:

Correct:

A high Risk Score of 90 indicates an unhealthy posture.

The presence of vulnerabilities (based on Security Analysis being enabled) further justifies the high Risk Score.

This combination of unhealthy posture and detected vulnerabilities aligns with the Risk Score and configuration provided.

D. The posture is unhealthy, but CPDI has not detected any vulnerabilities on the device:

Incorrect:

If no vulnerabilities were detected, the Risk Score would not be as high as 90, even if the posture were unhealthy.

Final Interpretation

From the configuration and Risk Score provided, the device's posture is unhealthy, and at least one vulnerability has been detected by CPDI.

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.
