WPA2 Personal (PSK) authentication relies on a shared secret (preshared key) configured on both the wireless LAN controller (WLC) and the client device. In the exhibit, the WLAN is configured with WPA2 and PSK (set-key ascii MyKey123), which means the network expects clients to use the same preshared key to authenticate. To enable client connectivity, the preshared key must be manually entered on each client device; this aligns the client and WLC authentication parameters. Options B, C, and D are unrelated to WPA2 Personal: MAC filtering is a security policy mechanism, Active Directory integration supports WPA2 Enterprise with 802.1X authentication, and client certificates are used for certificate-based EAP methods, not PSK. Cisco Wireless Core Technologies emphasize that PSK deployments require consistent key configuration across the WLAN and clients, and that the preshared key is the critical element for successful authentication. This ensures secure, encrypted communication while providing simple setup for small or branch deployments without an enterprise RADIUS infrastructure. Reference topics:Client Connectivity Configuration — WPA2 Personal, preshared key authentication, WLAN configuration, branch deployment WLAN security.

Client exclusion is a feature in Cisco Catalyst 9800 WLCs that allows the administrator to temporarily block clients exhibiting misbehavior, such as excessive retries, excessive bandwidth usage, or roaming issues. The IOS XE CLI command for enabling client exclusion in a WLAN policy isclient-exclusion < timeout > , where < timeout > defines the duration (in seconds) the client is prevented from associating with the WLAN. Option D correctly usesclient-exclusion 120to block the misbehaving clients for 120 seconds. Option A (exclude 120) is not valid IOS XE syntax. Option B (exclusionlist timeout 120) is also incorrect as it refers to internal exclusion lists, not the WLAN policy applied to live clients. Option C (security exclusion timeout 120) is invalid and does not configure client exclusion at the WLAN policy level. Cisco Wireless Core Technologies emphasize using client exclusion policies during high-density events or temporary network congestion to ensure network fairness, protect overall WLAN performance, and maintain connectivity for well-behaving clients.

AI Enhanced RRM is not a static-threshold tuning feature and it is not designed to simply raise AP transmit power. Cisco defines AI Enhanced RRM as a radio resource management technology that applies artificial intelligence and machine learning to optimize RF environments, uses distributed data collection from Cisco wireless controllers with cloud-based analytics, and automates adaptive RF parameter tuning for Cisco wireless networks.

The operational model is telemetry-driven. RF telemetry is collected from APs by the Catalyst 9800 WLC, sent through Cisco Catalyst Center to the Cisco AI Analytics Cloud, analyzed by RRM algorithms, and then configuration-change information is returned through Catalyst Center toward the managed wireless infrastructure. Cisco’s AI-Enhanced RRM deployment guide further identifies DCA, TPC, FRA, and DBS as examples of optimizations performed, meaning the feature enhances dynamic RF control rather than disabling it.

Therefore, option D is the only correct answer. Options A, B, and C describe either legacy/static behavior, harmful power-only logic, or a fixed RF design model that contradicts Cisco AI Enhanced RRM. Reference topics:Automation and AI — AI/ML-driven RF optimization, Catalyst Center assurance, RRM telemetry, DCA, TPC, FRA, and DBS.

When deploying a Lightweight Access Point (LWAPP) in a Cisco wireless network, proper Layer 3 configuration is essential for management and connectivity to the Wireless LAN Controller (WLC). Each LWAPP requires a valid IP address, subnet mask, and default gateway to communicate beyond its local subnet. In the exhibit, the AP is assigned 172.16.100.104/24, but the previously configured gateway was incorrect, preventing communication with the WLC. Cisco IOS XE requires that the AP’s IP interface be configured with the correct default gateway to route traffic properly. The correct syntax iscapwap ap ip < AP-IP > < Subnet-Mask > < Default-Gateway > . Option D matches the IP, subnet mask, and gateway for the given network, ensuring the AP can reach the WLC for LWAPP registration. Option A only changes the gateway without setting the IP explicitly, which is insufficient if the IP needs adjustment. Option B incorrectly configures the controller’s IP, which does not affect the AP’s default gateway. Option C uses an incorrect subnet mask (255.255.255.192), which would place the AP in a different subnet, breaking connectivity. Proper default gateway configuration is critical to avoid registration failures and management issues. Reference topics:Client Connectivity Configuration — LWAPP AP IP configuration, default gateway, WLC communication, Layer 3 reachability.

The failure is occurring during WPA/WPA2 key management, not during mobility anchoring. The radioactive trace showsFailed to validate eapol mic. MIC mismatchfollowed byFailed to validate eapol key m2, which means the authenticator and supplicant derived different key material during the PSK handshake. Cisco’s Catalyst 9800 client-connectivity troubleshooting maps this log pattern directly to a wrong password condition and lists the corrective actions as fixing the password on the endpoint or on the SSID/WLAN. The11r MIC validation failedphrase does not automatically make 802.11r the root cause; it only shows that the failed MIC validation occurred while Fast Transition key logic was in use. Disabling 802.11r would be a workaround only for client capability or FT interoperability issues, but the trace points to PSK mismatch. Removing the anchor WLC would break the intended DMZ anchoring design, and matching WLANs on foreign and anchor is required for anchor deployments, but it would not produce this EAPOL M2 MIC failure. The correct remediation is to ensure the client-entered PSK matches the WLAN PSK. Reference topics: WPA/WPA2-PSK authentication, EAPOL 4-way handshake, Catalyst 9800 radioactive trace analysis, and client connectivity troubleshooting.

The correct answer isreduction of co-channel interference. AI-RRM in Cisco Catalyst Center is designed for RF optimization, not IP addressing, software scheduling, or user identity classification. Cisco describes AI-enhanced RRM as applying artificial intelligence and machine learning to optimize RF environments and automate/adapt RF parameter tuning for Cisco wireless networks. This is directly tied to operational RF outcomes such as improved channel planning, transmit power behavior, channel width decisions, and better spectrum utilization.

Co-channel interference occurs when multiple AP radios operate on the same channel within hearing range, forcing devices to share airtime and increasing contention. AI-RRM uses telemetry, analytics, and learned RF behavior to recommend or apply more optimal RF configurations. Cisco specifically states that AI-enhanced RRM optimization can produce improvements such as up to a40 percent reduction in co-channel interferenceand SNR gains for wireless clients. Cisco’s AI-RRM deployment guidance also identifies AP radio distribution and utilization analysis as critical for minimizing co-channel interference and optimizing wireless performance.

Therefore, option B is the only operational outcome aligned with AI-RRM’s purpose. Reference topic:Automation and AI — Cisco Catalyst Center AI-RRM, RF analytics, RRM automation, channel optimization, and wireless AIOps.

For Cisco Catalyst 9176 APs deployed at remote sites without DHCP option 43, automatic WLC discovery can be accomplished using DNS-based CAPWAP controller discovery. By creating a DNS A record namedcisco-capwap-controller. < domain > that resolves to the WLC management IP address, APs can query DNS and locate their centralized controller automatically, eliminating the need for site visits or manual configuration. This method is preferred for large-scale or satellite deployments where APs may exist on different subnets and traditional DHCP-based discovery is unavailable. Option A is impractical because manually assigning static IPs to hundreds of APs is operationally complex and error-prone. Option B, using a multicast group, is not supported for cross-subnet controller discovery in CAPWAP; multicast is limited to local subnets. Option D (ap-discovery) is not a recognized standard for WLC discovery; Cisco specifically documentscisco-capwap-controlleras the required DNS entry for CAPWAP-based automatic discovery. This approach ensures zero-touch provisioning, simplifies network operations, and guarantees that APs join the correct controller, supporting centralized management and consistent configuration across multiple campuses. Reference topics:Wireless Network Implementation — CAPWAP discovery, DNS-based controller discovery, Catalyst 9800 WLC onboarding, zero-touch provisioning.

The command that enables 802.1X client authentication for this WLAN issecurity dot1x authentication-list ISE_GROUP. On a Cisco Catalyst 9800 WLC, the WLAN configuration defines Layer 2 security behavior, including whether the SSID uses 802.1X and which AAA method list is used for EAP/RADIUS authentication. Cisco documents the CLI workflow for 802.1X WLAN authentication as entering WLAN configuration mode and applyingsecurity dot1x authentication-list < authenticate-list-name > , explicitly describing this as the step to enable the authentication list for 802.1X security. Cisco’s Catalyst 9800 configuration example also shows the exact formsecurity dot1x authentication-list ISE_GROUPand states that the WLAN is then configured with 802.1X authentication.
