Designing Cisco Network Service Architectures (ARCH, legacy) — Question 43

Which three statements about 802.1X are true

Answer options

• A. it is IEEE standard
• B. It works only with wired devices
• C. It can allow and deny port access based on device identity

Correct answer: A, B, C

Explanation

The correct answer includes A, B, and C because 802.1X is indeed an IEEE standard that primarily operates in wired environments, and it is designed to control port access based on the identity of the device. While it works primarily with wired devices, it can also support wireless devices in certain configurations, making option B less universally applicable.
