HPE6-A78 Exam - 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.

Mirroring traffic to CPPM seems like a good idea, but I’m not clear on whether it’s necessary for just classifying endpoints.

I feel like we discussed sFlow in relation to traffic monitoring, but I can't recall if it directly helps with HTTP User-Agent strings.

I think option A is the way to go here. Creating a device fingerprinting policy that includes HTTP and applying it to the edge ports seems like the most direct way to get the necessary information to CPPM. I feel pretty confident about this one.

Okay, let me see if I can break this down. The key is that we need to get the HTTP traffic from the edge ports to CPPM so that it can use the User-Agent strings for classification. Option C, which talks about configuring CPPM as the sFlow collector, seems like it could work. I'll make a note to research sFlow a bit more.

Hmm, I'm a bit confused here. The question mentions that the company is only using CPPM and no other ClearPass solutions. So I'm not sure if option B, which talks about remote mirroring, would be the right approach. I'll need to think this through a bit more.

This seems like a straightforward question about configuring the ArubaOS-Switches to support the CPPM's requirement to use HTTP User-Agent strings for endpoint classification. I think option A is the correct answer.

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!

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?
