HPE Aruba Certified Network Security Expert (ACNSX) — Question 17

A company requires access by all users, guests, and employees to be authenticated. Employees will be authenticated using 802.1X, whereas guests will be authenticated using captive portal. Which type of authentication must be configured on an AOS-CX switch ports where both guests and employees connect?

Answer options

• A. Both 802.1X and captive portal
• B. 802.1X only
• C. Both 802.1X and MAC-Auth
• D. 802.1X, captive portal, and MAC-Auth

Correct answer: C

Explanation

The correct answer is C, as both 802.1X and MAC-Auth can be used to authenticate devices connecting to the same switch port, allowing for flexibility in authentication methods. Option A is incorrect because a captive portal is specifically for guest access, not required for employees. Option B is wrong because it does not account for guest authentication needs. Option D is incorrect as MAC-Auth is not necessary when both 802.1X and captive portal are in use.
