질문 # 99
An enterprise is using wireless as the main network connectivity for clients. To ensure wireless network availability, two standalone controllers are installed in the head office. APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried eping from the controller but fails.
Which protocol needs to be allowed between the networks that the controllers are installed?
정답：A
설명：
When eping (EoIP ping) fails between two Cisco Wireless LAN Controllers, it indicates that the data path of the mobility tunnel is blocked. In Cisco AireOS wireless networks, the mobility data path uses IP Protocol 97 (EtherIP -- Ethernet-over-IP encapsulation) for tunneling client traffic between the anchor and foreign controllers. This is distinct from the control path, which uses UDP port 16666. When the mobility data path (IP Protocol 97) is blocked by a firewall or ACL between the two controllers' networks, eping will fail because eping specifically tests the EoIP data encapsulation path. After a power cut, when clients disconnect and attempt to roam between APs on different controllers, the mobility tunnel must be operational for session continuity. If IP Protocol 97 is blocked, the mobility data plane cannot function, causing client disconnections during inter- controller roaming events. The other IP protocols listed (67, 77, 87) are not used for Cisco WLC mobility tunneling.
질문 # 100
A network engineer is configuring high availability on an access point. What is the maximum number of controllers that can be configured?
정답：A
설명：
When configuring high availability on a Cisco access point, the AP can be configured with a maximum of three controllers: a primary controller, a secondary controller, and a tertiary controller. This three-tier hierarchy defines the failover order - the AP first attempts to join its primary controller, then the secondary if the primary is unavailable, and finally the tertiary if both the primary and secondary are unreachable. After exhausting all three configured options, the AP enters a discovery process to find any available controller.
This three-controller configuration (primary, secondary, tertiary) allows network engineers to implement N+1 redundancy where critical APs can be directed to specific backup controllers in a deliberate sequence.
Limiting the configuration to only 2 controllers (as stated in Option B which would be incorrect) would reduce redundancy options for environments with geographically distributed controllers requiring specific failover paths.

질문 # 101
An enterprise network administrator is asked to set up an experimental WLAN for a collaboration project with a local service provider. The WLAN must be anchored to a WLC in the service provider data center using legacy mobility mode. After the configurations are completed on the WLCs and the firewalls in the path, the data path mobility tunnel is failing to come up. What should be performed by the administrator to debug the issue?
정답：B
설명：
When a data path mobility tunnel fails to come up between WLCs, one of the key troubleshooting steps is to verify whether the necessary ports are open through firewalls in the path. Cisco AireOS mobility tunnels use UDP port 16666 for mobility control traffic and IP Protocol 97 (EtherIP) for mobility data traffic in legacy mode. Establishing a Telnet connection from a local PC to the firewall on port 16666 tests whether the control path port is reachable and not being blocked by the firewall. If the Telnet connection fails, it confirms that the firewall is blocking port
16666, which would prevent the mobility control tunnel from establishing -- a prerequisite for the data tunnel. While a Telnet test to port 16666 specifically tests the control path, in practice this is the first verification performed when the data path cannot establish (since the data path depends on the control path being operational). IP Protocol 97 cannot be tested via Telnet (which is TCP).
질문 # 102
A customer has a Cisco wireless network with two Cisco Catalyst 9800 Series WLCs in a high availability cluster, 50 Cisco 2800I APs, and all SSIDs and services are 5 GHz only. A security mandate requires that rogue APs be scanned and identified in 2.4 GHz and 5 GHz bands without impacting existing client connectivity. How must the wireless network be reconfigured to meet the requirement without purchasing additional APs?
정답：B
설명：
The Cisco Aironet 2800 Series APs feature a dual-radio architecture with a dedicated 5 GHz radio (slot 1) and a Flexible Radio Assignment (XOR) radio (slot 0) that can operate in either 2.4 GHz or 5 GHz, or be assigned to monitor mode for scanning functions. Since all existing SSIDs and services are 5 GHz only, the slot 1 (dedicated 5 GHz) radio is responsible for all current client connectivity -- it must remain in Client Serving mode to maintain uninterrupted 5 GHz WLAN service. The XOR radio (slot 0), currently either idle or operating as a secondary 5 GHz radio, can be repurposed without impacting client service. Setting the XOR radio to Monitor mode enables it to continuously scan all channels across both the 2.4 GHz and 5 GHz spectrum for rogue AP detection, using the embedded CleanAir and WIDS capabilities. In Monitor mode, the XOR radio operates full-time as a dedicated scanner, providing rogue detection coverage on 2.4 GHz (previously uncovered since all services were 5 GHz) and supplementary scanning on 5 GHz.
This eliminates the need for additional dedicated monitor mode APs.
질문 # 103
Users who leave the office with a wireless headset must be able to hand oft the voice call with minimal disruption. The engineer drafted four possible Door plans for AP placement:
* red dots and arrows represent the direction of travel
* blue dots represent the AP placements
Which floor plan provides the requested functionality?
A)
B)
C)
D)
정답：D
설명：
VoWLAN handoff quality is fundamentally determined by the AP placement strategy relative to the direction of user movement. When a user is in motion carrying an active voice call, the roaming event must occur before signal quality degrades below the minimum acceptable VoWLAN threshold (typically -67 dBm for voice, with a minimum SNR of 25 dB). This requires the user to encounter increasing signal strength from a neighboring AP before the current AP ' s signal drops below the threshold. The optimal AP placement follows the principle of overlapping coverage along the predicted path of travel - APs must be positioned so that as a user moves, they progressively enter the coverage zone of the next AP while still within adequate range of the current one. Floor plan B represents the correct design where APs are positioned along the travel path with sufficient cell overlap (typically 15-20%) to ensure seamless 802.11r fast BSS transitions. Incorrect floor plans place APs perpendicular to travel direction, at path endpoints only, or with insufficient overlap zones - all of which create roaming dead zones where the handoff occurs too late, causing voice call disruption.
