Exam 350-050: CCIE™ Wireless Written (v2.0)

which WLAN or WLANs will still be correctly mapped to a local VLAN if an H-REAP mode AP moves between the two

Refer to the exhibit.

Two Cisco WLCs on a Cisco WiSM and in the same mobility group are both running 4.2.209.0
code. All the WLANs on both Cisco WLCs are configured for H-REAP local switching. Based on
the configurations that are shown, which WLAN or WLANs will still be correctly mapped to a local
VLAN if an H-REAP mode AP moves between the two controllers?

Which client or clients will need to process the multicast traffic?

Refer to the exhibit.

You have just configured multicast on the wired network and the controller. You configured the
multicast address on the Cisco WLC to be 239.0.1.25, with IGMP snooping disabled. Clients 1 and
3 are associated to AP1, and Client 2 is associated to AP2. All three clients are associated and
authenticated to WLAN 1. Using Client 1, you send an IGMP join request to test the multicast
application on the wireless network.
Which client or clients will need to process the multicast traffic?

Why were the APs unable to rejoin the Cisco WLC, and how can you prevent this from happening in the future?

After a scheduled downtime of your 5508 WLC, you notice that only a handful of the 100 APs are
rejoining the controller. All the APs are in the same subnet and use default settings. Cisco WLC
debugs indicate that the APs are sending discovery and join requests. Only after shutting down all
the switch ports that connect to the APs and turning five ports back on at a time can you rejoin all
the APs. Why were the APs unable to rejoin the Cisco WLC, and how can you prevent this from
happening in the future?
