Palo Alto Networks NetSec-Pro Exam - Topic 4 Question 2 Discussion

Actual exam question for Palo Alto Networks's NetSec-Pro exam

Question #: 2
Topic #: 4

Which set of attributes is used by IoT Security to identify and classify appliances on a network when determining Device-ID?

AIP address, network traffic patterns, and device type

BMAC address, device manufacturer, and operating system

CHostname, application usage, and encryption method

DDevice model, firmware version, and user credential

Show Suggested Answer

Suggested Answer: B

IoT Security uses MAC address, device manufacturer, and OS information to identify and classify devices via Device-ID.

''IoT Security uses passive network traffic analysis to fingerprint devices based on the MAC address, manufacturer, and operating system to ensure accurate classification.''

(Source: IoT Security Device-ID and Classification)

These attributes provide a robust, manufacturer-agnostic method to fingerprint IoT devices.

I thought it was more about the device type and network patterns, but now I'm second-guessing myself after reviewing the options.

I feel like it could be about IP addresses too, but I can't recall if they use that for Device-ID specifically.

I remember practicing a question similar to this, and I think the MAC address is definitely a key attribute.

The question seems straightforward, but I'm not sure if option D is a trick answer. Device model, firmware version, and user credential could also be used for Device-ID.
