   A company is deploying lightweight APs in a remote office. The APs will connect to a local switch, but the WLC is located at the headquarters and is reachable only over a routed WAN. The APs need to join the WLC. What is required for the APs to successfully join the WLC?

   • AThe switch ports must be configured as trunk ports.
   • BThe APs must be on the same VLAN as the WLC.
   • CThe APs must have IP reachability to the WLC management interface.
   • DThe APs must be configured with the WLC's hostname.

   A company is deploying a new WLC that will manage 200 APs. The WLC has four 1 Gbps uplink ports. To provide redundancy and increase bandwidth for management traffic, the engineer wants to combine these ports into a single logical link. Which feature should be configured on the WLC and the connected switch?

   • AConfigure each port as a separate access port and use Spanning Tree Protocol for redundancy.
   • BConfigure each port as a trunk port and rely on load balancing across the four links.
   • CConfigure a Link Aggregation Group (LAG) on the WLC and an EtherChannel on the switch.
   • DConfigure the WLC ports as a single port channel and the switch ports as individual access ports.

   A network engineer is troubleshooting a lightweight AP that is not providing wireless service. The AP is connected to a switch port configured as a trunk with native VLAN 1. The AP's management IP is on VLAN 10, and the SSID is mapped to VLAN 20. The AP can ping the WLC, but clients cannot get IP addresses. What is the most likely cause?

   • AThe AP is using an access port instead of a trunk.
   • BThe switch port does not allow VLAN 20 on the trunk.
   • CThe WLC is not configured with the correct management interface.
   • DThe switch port is a trunk, but the native VLAN is not the management VLAN.

   In a centralized WLAN architecture, what is the primary role of a wireless LAN controller (WLC)?

   • ATo forward all client data frames directly between wireless clients on the same AP without involving the wired network
   • BTo physically connect wireless clients to the wired network using Ethernet cables
   • CTo provide centralized management, configuration, and coordination of multiple access points
   • DTo replace the need for a switch by providing both wired and wireless connectivity

   A network administrator is deploying lightweight APs in a remote site. The APs are connected to a local switch, and the WLC is at the headquarters. The APs need to discover the WLC, but the DHCP server at the remote site does not support option 43. The administrator wants to avoid configuring each AP manually. What is the best alternative?

   • AConfigure DNS with a record for 'CISCO-WLC' pointing to the WLC's IP address.
   • BConfigure the APs with the WLC's IP address manually.
   • CUse Layer 2 broadcast discovery.
   • DUse a local WLC at the remote site.
