RSSI, or Received Signal Strength Indicator, is a measure of the detected power level of a radio signal at the receiver, expressed in dBm. It reflects the strength of the wireless signal received by the client or access point and is a critical metric for assessing coverage, link quality, and roaming decisions. Higher RSSI values (closer to 0 dBm) indicate stronger signals, while lower values (more negative) represent weaker signals. RSSI is used by Cisco wireless controllers and clients to make roaming decisions, select access points, and optimize transmit power levels. Option B, noise generated by interference, affects signal-to-noise ratio but does not define RSSI. Option C, QoS packet marking, pertains to network traffic prioritization, not RF measurements. Option D, wireless radio service ID, refers to identifying services on a network and is unrelated to signal strength measurement. Understanding RSSI is fundamental in RF planning, AP placement, and troubleshooting wireless coverage issues. Cisco Wireless Core Technologies emphasize monitoring RSSI to maintain adequate signal levels across the deployment, ensuring seamless connectivity and performance in high-density or challenging RF environments. Reference topics:RF Fundamentals — RSSI, signal strength, link quality, roaming, RF planning.

In Cisco Catalyst Center,device suppressionis the recommended method to prevent unnecessary alerts during planned maintenance windows. By enabling device suppression, the system temporarily suspends monitoring and alert generation for the selected devices while allowing telemetry collection to continue. This ensures that maintenance operations, such as firmware upgrades, configuration changes, or physical mesh AP servicing, do not trigger false-positive alarms. Once the maintenance window concludes, alerts resume automatically, and the engineer can verify that all services are operational and that no critical issues were overlooked.

Disabling telemetry on the WLC (option A) is not advised because it prevents visibility into device health and network performance, potentially causing gaps in monitoring data. Using SWIM (option B) is relevant for automated firmware updates but does not inherently suppress alerts during maintenance. Scheduling maintenance for devices (option C) without enabling device suppression may still generate alerts if the monitoring system detects device reboots or temporary unreachability.

Cisco wireless operational guides specifically highlightdevice suppression as the key tool for managing alerting behaviorduring planned events in mesh or enterprise WLAN deployments, providing a controlled approach to maintenance with minimal disruption to monitoring accuracy.

The correct authentication method isEAP-TLS. WPA2-Enterprise uses 802.1X/EAP authentication rather than a pre-shared key, and the supplicant, authenticator, and RADIUS authentication server participate in the enterprise authentication exchange. Cisco documentation states that in enterprise WPA/WPA2 operation, 802.1X/EAP is used for authentication and provides strong authentication between the client and authentication server.

The decisive requirement in the question iscertificate-based mutual authentication requiring both client and server certificates. Cisco explicitly describes EAP-TLS as requiring both server-side and client-side certificates, while PEAP requires only a server-side certificate and normally authenticates the client with password-based credentials inside the protected tunnel. Cisco Secure ACS documentation also states that EAP-TLS uses the certificates of the authentication server and the end-user client, enforcing mutual authentication.

MSCHAPv2 is a password-based inner authentication method, not certificate-based mutual authentication. PEAP protects credential exchange with a server certificate but does not inherently require a client certificate. TEAP can support flexible tunneled authentication, but the strict client-and-server certificate requirement maps directly toEAP-TLS.

TACACS+ is used for device administration, especially for GUI and CLI access to infrastructure platforms such as Cisco Catalyst 9800 WLCs, switches, and routers. Cisco defines TACACS+ as a security application that provides centralized validation for users attempting to access a device or network access server, and it separates authentication, authorization, and accounting functions for administrative control. Cisco ISE device administration documentation further states that TACACS+ is used to control and audit network device configuration, allowing devices to query ISE for administrator authentication and authorization while sending accounting records for logging administrator actions.

Therefore, the primary benefit is streamlined administrator access across platforms. Instead of maintaining local administrator accounts independently on every WLC or network device, TACACS+ enables centralized identity validation, role-based authorization, and consistent audit trails. Option A is incorrect because TACACS+ supports differentiated authorization rather than static grouping. Option B is the opposite of centralized accounting. Option D is inaccurate because TACACS+ is mainly for device administration, whereas client or endpoint network access is typically handled with RADIUS. Reference topics:Wireless Monitoring and Management — AAA for WLC administration, TACACS+ device administration, role-based access, and centralized audit control.

The correct command isreceiver ip address 198.51.100.10 57555 protocol tls-native profile spaces-profilebecause it matches the Cisco IOS XE model-driven telemetry subscription syntax used on Catalyst 9800 controllers. Cisco documents the receiver statement under telemetry ietf subscription as receiver ip address ip-address receiver-port protocol protocol profile name, and describes it as the command that configures the receiver IP address, port, protocol, and profile for telemetry notifications.

In the exhibit, the subscription already defines the telemetry feed: encode-tdl encoding, a native stream, the TDL URI for ewlc/wlan_config, the WLC source address, and an on-change update policy. What is missing is the collector destination. For Cisco Spaces or Catalyst Center-style integrations, the WLC must know where to export telemetry and which secure transport profile to use. Cisco troubleshooting examples for Catalyst 9800 telemetry use the same command structure: receiver ip address X.X.X.X 25103 protocol tls-native profile ... under the telemetry subscription.

Options A, B, and D are invalid because they reorder the CLI keywords. IOS XE telemetry configuration is parser-order sensitive: the command begins with receiver ip address, followed by the receiver port, then protocol, then profile. Reference topic:Wireless Monitoring and Management — Catalyst 9800 streaming telemetry, Cisco Spaces integration, TLS transport, and telemetry receiver configuration.

The correct answer isMake-before-break handover logic. This is a key feature in Cisco's Ultra-Reliable Wireless Backhaul (URWB) process that allows devices to establish a connection to the next AP (Access Point) before disconnecting from the current AP. This seamless transition ensures that there is no disruption in the wireless connection as the client roams between APs, which is especially important in environments where consistent, low-latency connectivity is essential, such as in real-time applications (e.g., voice or video).

Option A (Open roaming)refers to a method of allowing devices to roam freely across networks, but it doesn't address the specific need for a seamless handover process.

Option B (Fast client handoff)refers to methods used to speed up the roaming process, but it doesn’t specifically ensure that the next AP is connected before disconnecting from the current one.

Option C (802.11v high speed roaming)is an IEEE standard feature that helps optimize roaming behavior for fast-moving devices, butmake-before-break handover logicis the specific mechanism that allows for a seamless roaming experience.

Therefore,Make-before-break handover logic(Option D) is the correct answer as it directly addresses the need for devices to establish a reliable connection to the next AP during roaming before losing connectivity with the current one.
