質問 # 17
A customer wants a network engineer to design a Cisco wireless solution that will have redundancy through SSO and LAG. APs in the executive office must reassociate to the WLC as soon as possible in the event of a failure. The WLCs are located in a remote data center. The head office uses a WAN for connectivity with the data center. Which priority must be incorporated in the design to be assigned to the executive APs?
正解：B
解説：
Cisco WLC AP Failover Priority governs the order in which APs are processed when a WLC recovers and APs begin re-associating. The priority levels are: Critical, High, Medium, and Low.
During recovery situations, the WLC will accept and process AP join requests in order of priority -- Critical priority APs are processed first, before all other priority levels. In a deployment where the WLC is located in a remote data center connected via WAN, the join process for all APs is slower due to WAN latency and potential bandwidth constraints. Under these conditions, assigning Critical priority to executive office APs ensures they are at the front of the processing queue and restore service before lower-priority APs. The executive office designation implies business- critical operations requiring the fastest possible wireless restoration -- a requirement that directly maps to the Critical priority level.

During a client roaming event, which device is responsible for communicating the new Layer 2 EID mapping of a wireless supplicant to the fabric domain?
正解：B
解説：
During a client roaming event in a Cisco SD-Access fabric deployment, the Wireless LAN Controller (WLC) is responsible for communicating the new Layer 2 Endpoint ID (EID) mapping of a wireless supplicant to the fabric domain. In the SD-Access architecture, the WLC acts as a mobility orchestrator and serves as the interface between the wireless domain and the wired fabric. When a client roams from one AP to another, the WLC detects the roaming event and updates the fabric control plane with the new EID-to-RLOC (Routing Locator) mapping by notifying the fabric control plane node (CP). This ensures that the fabric knows the client's new location and can route traffic correctly without interruption. The Border Node (BN) handles traffic between the fabric and external networks. CP1 and CP2 are control plane nodes that maintain the mapping database but receive EID update notifications from the WLC -- they do not initiate the EID mapping communication themselves.
質問 # 19
A company is upgrading its wireless infrastructure and is in a state of transition. Some parts of the company's building still run on the legacy WLC. The new WLC is not located at the same site as the legacy WLC. The company requires seamless client inter-controller roaming between the new WLC and the legacy WLC, with no disruptions. Both WLCs are separated by firewalls. Which troubleshooting command validates that the mobility control packets between the WLCs can be sent and received?
正解：C
解説：
The command 'debug mobility handoff enable' is used to validate the mobility control packets between Wireless LAN Controllers (WLCs). This command enables debugging of the handoff process, which is critical for ensuring seamless client roaming between controllers. When WLCs are separated by firewalls, it is essential to confirm that mobility control packets can traverse these firewalls without being dropped or rejected. The 'debug mobility handoff enable' command allows network administrators to monitor the handoff process in real time and identify whether mobility PDUs are being exchanged successfully. If mobility control packets are being blocked by the firewall, this debug output will show failures in the handoff sequence. This command directly validates bidirectional mobility traffic flow, making it the correct troubleshooting tool for the scenario described.
質問 # 20
A customer has two Cisco Catalyst 9800 Series WLCs named WLC-A and WLC-B in an N+1 configuration with the same WLANs but different Layer 3 interfaces for each WLC, and APs in local mode. WLC-A manages Building A APs and WLC-B manages Building B APs. The customer wants users to remain connected and retain their session state including the IP address when moving between buildings. How must this requirement be incorporated into the design?
正解：C
解説：
The requirement for users to retain their session state and IP address when roaming between buildings managed by different WLCs is a Layer 3 roaming scenario. In Cisco's wireless architecture, IP address preservation across controller boundaries is achieved through inter- controller mobility -- specifically the foreign-anchor mobility tunnel mechanism. When a client roams from Building A (WLC-A) to Building B (WLC-B), WLC-B becomes the foreign controller and WLC-A becomes the anchor controller. WLC-B tunnels the client's traffic back to WLC-A, allowing the client to retain its original IP address even while physically associated to an AP managed by WLC-B. This requires a mobility tunnel between WLC-A and WLC-B with both controllers configured in the same mobility group name -- the group name is the trust identifier that permits the mobility tunnel and anchor- foreign relationship to form. Without the same group name, the controllers will not form a trusted mobility peer relationship.
質問 # 21
A consulting engineer for a copper mine is trying to extend the network connectivity of autonomous trucks via Cisco IW3702 APs. The WGB design requirements include: latency- sensitive application (truck slows at 10 sec, stops at 20 sec of connection loss), aggressive scanning and roaming, enterprise-grade security without certificates on each AP, multiple clients in different VLANs on the WGB, and channel scan parameters restricted to only channels in the truck path. Which design approach meets the requirements?
正解：C
解説：
This WGB (Workgroup Bridge) design scenario requires satisfying multiple simultaneous constraints. EAP-FAST (Flexible Authentication via Secure Tunneling) is the correct authentication protocol because it provides enterprise-grade 802.1X security using protected access credentials (PAC) without requiring a certificate to be installed on each AP or WGB device
-- directly satisfying the enterprise-grade security without certificates requirement. EAP-TLS (Options B and D) requires client certificates on every authenticating device, which is explicitly excluded. Mobile station mode is required rather than static mode (Options C and D) because mobile station mode enables the WGB to aggressively scan and roam to optimal mesh neighbors dynamically, evaluating neighbor signal quality and switching to better RAPs/MAPs as the truck moves along its path. Static mode fixes the WGB to a specific channel or AP, preventing the aggressive scanning and roaming required for the latency-sensitive application. The dot1q- capable switch connection supports multiple clients in different VLANs via 802.1Q VLAN tagging between the WGB and the truck's local network switch.
