In this scenario where branch wireless users can still associate locally but cannot access head office services due to WAN downtime indicates that Cisco FlexConnect is likely in use. The correct elements are: A - authentication-local/switch-local: This means that client authentication and data switching are happening locally at the branch. E - standalone mode: With WAN down, FlexConnect APs operate in standalone mode allowing clients to associate even without connectivity back to WLC. F - WEB authentication: This could be used as an authentication method regardless of WAN state since it’s processed locally at AP level. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

If the Cisco 5520 Series Wireless LAN Controller is no longer manageable via the network after implementing a CPU ACL, permit statements must be added to the top of the ACL in both directions (A). These statements should specify the network from which management is allowed and the virtual interface of the controller to ensure proper management access. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The issue is likely caused by the CPU ACL on the controller, which is blocking HTTP/HTTPS traffic from the guest clients. When a WLAN with Web Authentication is used, the wireless client’s browser is redirected to a web page for authentication. If the CPU ACL is configured to only allow controller web management traffic from the IT subnet, it may inadvertently block the necessary HTTP/HTTPS traffic for the Web Authentication process, leading to a timeout on the wireless client browser. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, specifically the sections discussing CPU ACLs and their impact on network traffic.

The Out-of-Sync alarms in Cisco Prime Infrastructure typically indicate that there is a discrepancy between the configuration of the APs as known by Prime Infrastructure and their actual configuration. To resolve this issue, the engineer can either manually synchronize the APs from Cisco Prime Infrastructure (A) or enable automatic synchronization on Cisco Prime Infrastructure © to ensure that the AP configurations are updated automatically. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

On the Global Configuration page of a Wireless LAN Controller (WLC), for an Access Point (AP) to use IEEE 802.1X for authenticating to the wired infrastructure, it is necessary to configure a RADIUS shared secret. This secret will be used by the AP as part of its credentials when communicating with a RADIUS server during the authentication process. References: (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

To prevent the network from a Layer 2 flooding of multicast frames and ensure a seamless transfer of multicast data to the client when roaming, IGMP snooping should be enabled on the WLC. This feature allows the WLC to monitor and control multicast traffic at Layer 2, preventing unnecessary multicast forwarding.

 The configuration for the Rogue Rule named “Rule 1” is set to classify an access point (AP) as malicious if it meets certain conditions. The rule specifies that the AP must have a Minimum RSSI (Received Signal Strength Indicator) of less than or equal to -65 dBm and must have been seen for a Time Duration greater than or equal to 3600 seconds. Among the options provided, both A and C have been seen for more than 3600 seconds, which satisfies the Time Duration condition. However, for the RSSI condition, only option C with an RSSI of -60 dBm meets the criteria of being less than or equal to -65 dBm. Therefore, option C is the correct answer, as it fulfills both conditions set by the Rogue Rule.

 The issue described indicates that authentication requests from the wireless network to the RADIUS server are being dropped. This problem is often due to a mismatch in shared-secret keys between the wireless controller and the RADIUS server. The shared secret is a password-like value that must be configured on both sides to ensure secure communication. By configuring both sides with matching shared-secret keys, it ensures that authentication messages are properly encrypted and decrypted by each party, allowing for successful user connection. References: (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

The Cisco Aironet 1800s Active Sensor is designed to work with Cisco DNA Center. It is a compact, flexible sensor that provides insights into the wireless network’s health and is used for proactive monitoring and troubleshooting. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, which includes information on Cisco DNA Center and compatible AP models.
