Which of the following WLC interfaces or ports should be used to make a connection between a VLAN and a WLAN?
Distribution system ports
Management interface
Service port
Virtual interface
Dynamic interface
Answer explanation
WLC dynamic interfaces are used to make a logical connection between a wired VLAN and a WLAN. On an IOS-XE WLC, the dynamic interface is simply the respective VLAN itself. Distribution system ports connect the WLC to the physical network where VLANs exist, while the WLC touches wireless users through its APs and WLANs. The management interface is used for only WLC management traffic. The service port is used for out-of-band management, and the virtual interface is used to relay client mobility functions like DHCP and web authentication.

What is the default session timeout that a controller enforces on wireless clients that connect to a WLAN?
60 seconds
600 seconds
1800 seconds
86400 seconds
0 seconds
Answer explanation
By default, clients are limited to a session timeout of 1800 seconds (30 minutes). You can configure the session timeout to be a value from 0 (no timeout) to 86400 seconds; if 802.1x is in use, the minimum timout is 300 seconds.

Suppose a Cisco WLC has one service port, one redundancy port, four distribution system ports, and one console port. To gain the most advantage out of the four distribution system ports with load balancing and redundancy, which of the following would be the best strategy?
Configure the distribution ports individually as access links.
Configure the distribution ports as a trunk link LAG.
Configure the distribution ports individually as trunk links.
Configure the distribution ports as an access link LAG.
Answer explanation
Because the WLC has four distribution system ports, they should be configured as a single logical LAG (link aggregation group). Distribution system ports should also always be configured as trunk links so that multiple VLANs can be mapped to WLANs on the WLC.

Suppose you need to connect two new Cisco APs to a switched network. One is an autonomous AP, the other a lightweight AP. The APs will be used to provide four WLANs that map to four VLANs. Which of the following correctly describes the wired network link that connects to the autonomous and lightweight APs, respectively?
access mode, access mode
access mode, trunk mode
trunk mode, access mode
trunk mode, trunk mode
Answer explanation
The autonomous AP will need a wired link configured in trunking mode so that all four VLANs can be carried over the single link. The lightweight AP needs its wired connection configured in access mode. The same four VLANs will be available at the AP, but they will be carried between the WLC and AP over CAPWAP tunnels.

When configuring a wireless LAN from an AireOS WLC, you create a dynamic interface and a wireless LAN. Which answers identify the correct configuration area where you configure the stated parameters? (Choose three answers.)
VLAN ID on the dynamic interface creation page
WLAN ID on the dynamic interface creation page
WLAN ID on the WLAN creation page
SSID on the dynamic interface creation page
SSID on the WLAN creation page
Answer explanation
The dynamic interface and WLAN configurations in an AireOS WLC define the settings for a LAN's wired (dynamic interface) and wireless (WLAN) sides. The dynamic interface creation page gives input fields for:
• A dynamic interface name
• The numeric VLAN ID used on the wired network (the distribution system)
The wireless LAN creation page allows for the definition of:
• The wireless LAN profile name
• The SSID
• A numeric WLAN ID (1-512)
To connect the parameters together, the WLAN configuration page has a field that references the dynamic interface name.
Of the various answers, one correct answer notes that you must configure the VLAN ID on the dynamic interface creation page. The other two correct answers list settings made on the WLAN creation page: the WLAN ID and the SSID.
