Using Aruba best practice what should be enabled for visitor networks where encryption is needed but authentication is not required?

• A. Wi-Fi Protected Access 3 Enterprise
• B. Opportunistic Wireless Encryption
• C. Wired Equivalent Privacy
• D. Open Network Access

Answer: (B)

The idea here is to provide encryption without requiring any user credentials on a guest network. Opportunistic Wireless Encryption delivers exactly that: it enables encryption on an open network by having the access point and each client derive a unique session key during association. This means traffic is protected from eavesdroppers even though no password or certificate is entered, which matches the need for encryption without authentication. WPA3 Enterprise would require 802.1X authentication and a backend, which adds authentication that isn’t desired here. Wired Equivalent Privacy is an outdated, insecure standard that isn’t recommended for modern networks. An Open Network Access would be truly unencrypted, leaving traffic exposed, so it doesn’t meet the encryption requirement. Therefore, Opportunistic Wireless Encryption is the best fit for visitor networks where encryption is needed but authentication is not required.
