Q86. Which two statements correctly describe how EX Series switches use captive portal for Layer 2 authentication? (Choose two.)

The captive portal is the default Layer 2 authentication method that is applied before other methods such as 802 1X or MAC RADIUS.

The captive portal authentication allowlist works for devices that do not have HTTP capabilities.

The captive portal is configured on Layer 3 interfaces and does not participate in Layer 2 authentication on EX Series switches.
