HP Exam HPE6-A78 Topic 3 Question 77 Discussion

Actual exam question for HP's HPE6-A78 exam
Question #: 77
Topic #: 3
[All HPE6-A78 Questions]

A company has Aruba Mobility Controllers (MCs), Aruba campus APs, and ArubaOS-Switches. The company plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type. This company is using only CPPM and no other ClearPass solutions.

The ClearPass admins tell you that they want to use HTTP User-Agent strings to help classify endpoints.

What should you do as a part of configuring the ArubaOS-Switches to support this requirement?

Show Suggested Answer Hide Answer
Suggested Answer: C

ArubaOS-Switches can use sFlow technology to sample network traffic and send the samples to a collector, such as ClearPass Policy Manager (CPPM), for analysis. sFlow can be configured to capture various types of traffic, including HTTP, which typically contains User-Agent strings that can be used for device fingerprinting and classification.

To support the requirement for using HTTP User-Agent strings to classify endpoints, the switches would need to be configured to send sFlow samples containing HTTP traffic to CPPM. CPPM would then analyze these samples and use the User-Agent strings to classify the devices.

Therefore, the correct action to configure ArubaOS-Switches would involve:

Configuring CPPM as the sFlow collector on the switches.

Enabling sFlow on the edge ports that connect to endpoints.

This approach allows the network traffic to be analyzed by CPPM without requiring any additional mirroring or redirection of traffic, which would be resource-intensive and potentially disruptive to network performance.

I wonder if any of these choices involve turning the switches into pretzel-shaped traffic collectors. That would be a fun engineering challenge!

Wait, did they really ask us to mirror traffic to CPPM's IP address? That's like handing your homework to the teacher before they even ask for it!

A) Create a device fingerprinting policy that includes HTTP, and apply the policy to edge ports.

Hmm, I'm not sure about these options. Wouldn't it be simpler to just enable HTTP inspection on the ArubaOS-Switches and let CPPM pull the data directly?

Exactly. We should focus on configuring the switches to work with CPPM in this specific scenario.

I see. So, we need to choose the option that aligns with using HTTP User-Agent strings for endpoint classification.

I'd go with C. Configuring CPPM as the sFlow collector is a clean way to capture the necessary data without messing with port mirroring.

Option B seems the most logical. Mirroring the edge port traffic to CPPM allows it to analyze the HTTP User-Agent strings and classify the endpoints.
