EC688 wrong - phreak - 06-12-2022

which option must be used to support a wlc with an ipv6 management address and 100 cisco aironet 2800 series access points that will use dhcp to register?

answer is showing 43 but that is for ipv4
answer should be 52 (https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-0/IPV6_DG.html#pgfId-102185)


The CAPWAP protocol allows a lightweight access point (AP) to use DHCP to discover a wireless controller to which it is connected to. Cisco lightweight APs running 8.0 and above support DHCP discovery for both IPv4 and IPv6 networks:

[Image: blank.gif]IPv6—Cisco lightweight APs implement DHCPv6 option 52 (RFC 5417) to supply the IPv6 management interface addresses of the primary, secondary, and tertiary wireless controllers.
