Cisco® 300-430 Exam Practice Questions (P. 2)

GPT-4o - Answer

In situations where OfficeExtend is used but users are experiencing issues accessing local resources like network printers, enabling the OEAP split tunnel feature is an effective solution. This configuration allows specific traffic to bypass the VPN tunnel, providing direct access to local network resources while still maintaining secure connectivity to corporate services. This setup minimizes the traffic load through the corporate network and ensures that local resources such as printers remain accessible to remote workers.

GPT-4o - Answer

The correct choice, 'remote LAN' (RLAN), relates to configuring OEAP to use multiple ports to expand the wired network capabilities. RLAN allows different ports on the OEAP to be associated with distinct VLANs, effectively extending the enterprise network's reach while maintaining appropriate security and segmentation. This is crucial for scenarios where multiple wired connections are necessary in a remote location linked via an OEAP.

GPT-4o - Answer

While FlexConnect local authentication does involve some aspects of client IP assignment and traffic handling, it primarily deals with authentication processes. The scenario described in the question, where IP subnet assignment dynamically controls where traffic is offloaded or tunneled, fits better with VLAN-based central switching. This feature ensures that if the client's assigned subnet is available at the remote site, traffic can be offloaded locally. If not, it's tunneled back to the WLC, aligning perfectly with the requirements stipulated.

GPT-4o - Answer

When encountering issues where APs are trying to associate to a WLC behind a NAT, using the correct settings can make a significant difference. In a scenario where both internal and external access points need to find and communicate with the WLC — like having Local Mode and OfficeExtend APs operational together — you should use the command 'config network ap-discovery nat-ip-only disable'. This configuration allows for the use of both NAT and non-NAT IP addresses in the discovery process, ensuring that APs can locate and connect to the WLC regardless of their network position. This command effectively reconciles AP discovery issues in mixed deployment environments.

GPT-4o - Answer

To enable 802.11r and CCKM in a distributed enterprise environment with APs configured in FlexConnect mode, the crucial implementation is the creation of FlexConnect groups. This setup is essential because CCKM fast roaming and consistent support for 802.11r require APs to manage authentication and reassociation swiftly and locally. FlexConnect Groups facilitate seamless roaming between APs within the same group by maintaining these fast transition capabilities, ensuring both efficient management and enhanced security across the wireless network.

GPT-4o - Answer

To rectify the issue of varying WLAN functionality in different AP modes, configuring a Cisco FlexConnect group with WLAN-VLAN mapping is required. This setup ensures each WLAN is correctly associated with its respective VLAN, thereby facilitating optimal flexibility and performance in either AP mode. This approach manages the VLAN associations effectively when APs switch between Local and FlexConnect modes, addressing the unique requirements of each WLAN under different operational modes.

GPT-4o - Answer

When configuring the network for voice traffic class of service with regard to queue order and DSCP settings, the correct command is indeed `mls qos trust dscp`. This command ensures that the switch port respects the DSCP markings on incoming packets for queue decisions and maintains these markings when packets are forwarded. This setting is crucial for maintaining the integrity of voice traffic prioritization across network segments. Be mindful that while `mls qos trust cos` seems related, it prioritizes based on CoS tags, which primarily affects internal switch traffic handling rather than inter-switch DSCP consistency.

GPT-4o - Answer

AutoQoS on the Cisco Catalyst 9800 Series Wireless Controller is designed to match traffic based on predefined conditions and then assigns each of these matched packets into specific QoS groups. This functionality aids in prioritizing traffic efficiently and ensures better network performance and management. This specific behavior is fundamental for optimizing wireless network traffic which corresponds with the complexities and demands of modern network environments.
