Wireless Infrastructure

A network engineer is deploying a new wireless LAN controller (WLC) in a campus network. The WLC must manage 200 access points across three buildings. The engineer configures the WLC with a management IP address and enables CAPWAP. However, the access points fail to join the WLC. The APs are in the same VLAN as the WLC and can ping the WLC's management IP. What is the most likely cause of the APs not joining?

A company is deploying a new wireless network in a large warehouse. The network engineer must choose between using a centralized WLC architecture (with CAPWAP tunnels) or a converged access (SD-Access) wireless architecture. The warehouse has high-density client areas and requires low latency for real-time applications like voice and video. Which architecture should the engineer choose and why?

A network engineer is troubleshooting a wireless network where clients in a conference room experience intermittent connectivity. The engineer notices that the access point in that room is showing a high number of CRC errors on its uplink interface. The AP is connected to a Cisco 9300 switch via a copper cable. What is the most likely cause of the CRC errors?

An engineer is configuring a new Cisco 9800 WLC in a branch office. The WLC will manage 50 APs and must provide guest access with a captive portal. The engineer configures a guest SSID with open authentication and a redirect ACL for the captive portal. However, after the configuration, clients can associate to the guest SSID but cannot reach the captive portal page. What is the most likely cause?

A network engineer is deploying a wireless mesh network using outdoor access points. The mesh APs are configured to use 802.11a/n on the 5 GHz band for backhaul and 802.11b/g/n on the 2.4 GHz band for client access. The engineer notices that the mesh backhaul links are unstable and have high packet loss. What is the most likely cause of the instability?

An engineer is configuring a Cisco 9800 WLC for high availability using a pair of WLCs in an active/standby configuration. The engineer configures the same SSID and security settings on both WLCs. However, when the active WLC fails, clients that were connected to the active WLC do not automatically reconnect to the standby WLC. What is the most likely cause?

A network engineer is troubleshooting a wireless network where clients in a specific area report slow speeds and frequent disconnections. The engineer uses a spectrum analyzer and finds high utilization on channel 11 in the 2.4 GHz band. The engineer also notices that several neighboring access points are using channel 11. What is the most likely cause of the issue?

An engineer is deploying a wireless network in a hospital that requires strict security and client isolation. The network must support 802.1X authentication for employees and a separate guest SSID with a captive portal. The engineer configures the WLC with RADIUS servers for 802.1X and a local web server for the captive portal. However, guest users can access the internal network after authentication. What configuration change is needed?

A network engineer is upgrading a legacy wireless network that uses autonomous access points to a centralized WLC-based architecture. The engineer has installed a Cisco 9800 WLC and is converting the autonomous APs to lightweight mode. After the conversion, the APs join the WLC, but the engineer notices that the APs are not broadcasting any SSIDs. What is the most likely cause?
