In a FlexConnect group with local switching but central DHCP, clients can use features like multicast and static IP without any issues. However, fast roaming, which allows clients to move seamlessly between access points with minimal delay, requires the access points to handle client information locally. If the configuration is changed to allow local DHCP, then the access points can cache client credentials, enabling fast roaming.

To meet the requirement of allowing employees to easily onboard their personal devices and visitors to connect without reception desk intervention, configuring a self-registration guest portal on Cisco ISE is the appropriate solution. This feature enables guests to create their own accounts and gain network access, streamlining the process for both employees’ personal devices and visitors. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The Cisco Aironet 600 Series OfficeExtend APs support various Layer 2 security options, including WPA+WPA2 and 802.1X. WPA and WPA2 provide secure encryption for wireless data, while 802.1X offers a robust authentication framework. These security options ensure that the wireless network is protected against unauthorized access and data breaches, which is crucial for remote workers connecting to the corporate network. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 Cisco AVC (Application Visibility and Control) on a Cisco Wireless LAN Controller (WLC) is used to prioritize traffic by marking the packets. For Cisco IP cameras that use the wireless network, the AVC rule would be configured to mark the packets with a specific QoS value, ensuring that the video traffic is treated with higher priority as it traverses the network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

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

When setting up identity-based networking with ISE and configuring AAA override on the WLAN, the attributes that can be used to change the client behavior from the default settings include the DNS server and DSCP value. The DNS server attribute allows for the specification of a DNS server per client, which can be essential for directing traffic through specific network paths or applying policies based on domain name resolutions. The DSCP value attribute is used to mark the packets with a specific Quality of Service (QoS) level, which can prioritize or deprioritize traffic as needed. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

For a network using EIGRP and BGP within a single domain from a single source, Protocol Independent Multicast Sparse Mode (PIM-SM) is the most suitable multicast routing to be implemented. PIM-SM is efficient for networks with a large number of networks and few receivers, which seems to be the case for an all-company video meeting.

In a historic building where adding APs is challenging, the best approach to implement intrusion protection with a focus on on-channel attacks is to use APs in monitor mode with the Wireless Intrusion Prevention System (WIPS) submode. This setup allows the APs to dedicate their time to scanning the environment for threats without serving clients, which is suitable given the adequate coverage and the need to monitor for attacks. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

Local EAP (Extensible Authentication Protocol) allows wireless LAN controllers to directly authenticate clients using an internal database, which can be useful when external RADIUS servers are unreachable. By enabling local EAP, client devices can still connect to wireless networks even if communication with RADIUS servers fails, ensuring continuous network access for users. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To ensure reliable streaming of video content on the wireless network between Cisco FlexConnect APs, Multicast Direct must be enabled. This feature allows for efficient multicast traffic delivery by converting multicast streams into unicast streams for each client, which guarantees delivery even in environments where reliable multicast is not feasible. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
