A hospital is deploying a wireless network to support critical medical devices that use multicast for real-time data streaming. The network uses a Cisco Catalyst 9800-CL WLC and lightweight APs. To ensure reliability, the network administrator must configure the system so that multicast traffic is converted to unicast for each subscribed client. However, they also need to prevent the WLC from being overloaded with IGMP reports from the wired network. Which configuration combination on the Catalyst 9800 WLC achieves these specific goals?

A retail company uses Cisco DNA Center Assurance to monitor its wireless network. An alert is generated for a specific AP indicating 'High RF Interference'. An engineer needs to determine the source of this non-Wi-Fi interference. Which feature within Cisco DNA Center Assurance should be used to classify the interfering device, such as a microwave oven or Bluetooth speaker?

A corporation is securing its wireless network using 802.1X with EAP-TLS. They are using Cisco ISE as the RADIUS server. A new requirement mandates that wireless clients must be validated against a specific value in the Subject Alternative Name (SAN) field of their certificate, in addition to the standard validation checks. Where in the Cisco ISE Authentication Policy is this specific check configured?

An engineer is deploying a FlexConnect wireless network for a large distribution center with multiple buildings. The design requires clients to maintain their IP address when roaming between APs connected to different switches, which are in different Layer 3 subnets. The WLCs are centralized in a corporate datacenter. Which two features must be configured to ensure seamless L3 roaming for the clients? (Select TWO)

A university is using Cisco CMX for location analytics in its library. To improve the accuracy of client location tracking for generating footfall heatmaps, the administrator plans to implement Cisco Hyperlocation technology. What is the primary hardware component that enables Hyperlocation on compatible Cisco Aironet APs?

To protect a Cisco Catalyst 9800 WLC from denial-of-service attacks, an administrator needs to create an access control list that filters traffic destined for the controller's CPU itself. This ACL should be applied to all traffic arriving at the controller, regardless of the ingress interface. Which type of ACL must be configured for this purpose?

A network engineer is configuring Quality of Service (QoS) on a Catalyst 9800 WLC to support voice over Wi-Fi clients. The corporate policy requires that all voice traffic originating from wireless clients be marked with a DSCP value of EF (46). Which configuration item within the C9800's policy model is used to apply this DSCP marking to the upstream traffic?

A warehouse is deploying an RFID asset tracking system that uses active Wi-Fi RFID tags. The tags associate with the wireless network to send their location data. The network is managed by a Cisco WLC and Cisco CMX. To ensure that CMX can accurately track these tags without requiring them to fully authenticate as data clients, which feature must be enabled on the WLC?

During a wireless network deployment, an engineer observes that Bonjour services, such as AirPrint, are not discoverable across different VLANs. The network consists of a Catalyst 9800 WLC, and clients are on a different VLAN than the Bonjour service providers. Which feature must be enabled on the WLC to facilitate this cross-subnet discovery?

True or False: When a FlexConnect AP is in standalone mode due to a WAN outage, it can perform 802.1X authentication for new clients if FlexConnect Local Authentication is enabled, even if the central RADIUS server (ISE) is unreachable.
