질문 # 120
A university lecture hall has a Cisco wireless high-density network with this configuration: * 5 GHz only * 20- MHz channels * UNII-1, UNII-2, and UNII-2E channels * TPC minimum = 8 * TPC maximum = 14 The lecture hall is 200 feet by 100 feet and has 16 Cisco APs that use directional antennas. Which feature must be included in the design to mitigate and reduce high-channel utilization from rogue APs?
정답：C
설명：
Receive Start of Packet (RxSOP) is a Cisco proprietary mechanism that defines the minimum received signal threshold at which an access point will acknowledge an 802.11 frame and begin processing it. In a high- density lecture hall environment with 16 APs and directional antennas on a constrained channel plan, rogue APs operating on the same or adjacent channels contribute directly to elevated channel utilization by causing unnecessary medium contention, virtual carrier sensing via NAV, and clear channel assessment deferral. By raising the RxSOP threshold on the legitimate APs, the engineer creates a higher signal floor requirement - only signals above the configured RxSOP level are processed. Signals from distant rogue APs, arriving below this threshold, are silently discarded rather than processed, preventing them from consuming airtime through CCA deferral and NAV mechanisms. Band select (Option A) encourages dual-band clients to move to 5 GHz but does not address rogue interference. 802.11w (Option B) is a management frame protection standard, not an interference mitigation tool. DFS detection (Option D) is for radar avoidance on UNII-2 channels, not rogue AP mitigation.

질문 # 121
An engineer configured the optimized client roaming on Cisco WLC with an RSSI threshold of -72 dBm. Clients report frequent disconnections. What must be configured for the AP to guide the client to a better AP?
정답：D
설명：
The scenario presents a critical distinction in where Cisco WLC features are configured.
Optimized roaming on Cisco WLC is a radio-level feature that monitors connected client RSSI and, when a client's signal falls below the configured threshold (-72 dBm), triggers a disassociation to force the client to reconnect to a stronger AP. However, without a mechanism to guide the client proactively before reaching the threshold, clients that disassociate simply reconnect to whatever AP their device selects, potentially causing the reported frequent disconnections. BSS Transition Management (802.11v) is configured at the SSID level and provides the complementary mechanism: before the client reaches the RSSI threshold, the AP sends a BSS Transition Management Request pointing the client toward a specific target AP with stronger signal. The correct architecture requires: optimized roaming configured at the radio level (triggering disconnection when RSSI falls too low) combined with BSS transition enabled at the SSID level (guiding the client to a better AP before forced disconnection).
질문 # 122
A customer has a centralized wireless deployment with N+1 high availability and few open authentication SSIDs configured. After failover, all APs are broadcasting all SSIDs, but the clients are assigned IP addresses from a different subnet. The WLANs on both WLCs are configured with the same dynamic interfaces. Which feature must be incorporated in the wireless design of the second controller?
정답：D
설명：
VLAN Select is a feature that allows for the dynamic assignment of clients to different VLANs from a pool based on various criteria, such as load balancing or location. In a centralized wireless deployment with N+1 high availability, if clients are receiving IP addresses from a different subnet after failover despite the WLANs being configured with the same dynamic interfaces, the issue is that the second controller ' s WLAN interface mapping resolves to a different VLAN or DHCP scope. VLAN Select ensures that client VLAN assignment is consistent regardless of which controller the client connects to, preventing the subnet change behavior observed during failover. Without VLAN Select, even identically named dynamic interfaces on two WLCs may map to different VLANs if the underlying switch configuration differs. RF Protocol (Option A) controls radio parameters. AP Groups (Option B) control SSID and VLAN assignments per AP cluster. AAA Override (Option D) allows RADIUS servers to assign per-user VLANs, which requires authentication - but these SSIDs use open authentication.

질문 # 123
A school deploys a Cisco wireless infrastructure in its classrooms to support a high density of mobile devices. The network administrator wants to bond channels in groups of two and only allow APs to send 802.11 management frames at 24 Mbps. What should be included in the design to accomplish this objective?
정답：B
설명：
For a high-density classroom deployment using 5 GHz with channel bonding in groups of two (40 MHz channels), the correct configuration is to set the channel width for 802.11a (5 GHz) to 40 MHz and set the 24 Mbps data rate to Mandatory. Channel bonding refers to combining two adjacent 20 MHz channels into a single 40 MHz channel, doubling the channel width. Since the requirement specifies 5 GHz operation (where high-density design is appropriate), this must be applied to the 802.11a radio profile, not 802.11b (which operates only on 2.4 GHz). Setting 24 Mbps as Mandatory ensures that APs transmit management frames (beacons, probe responses, and other control frames) only at 24 Mbps -- this is how the 'only allow APs to send 802.11 management frames at 24 Mbps' requirement is implemented.
질문 # 124
A wireless engineer must design a backhaul link. The engineer has a mesh access point that has a wired connection back to the infrastructure. What must be changed in the AP role before a change is made in the AP mode?
정답：C
설명：
In Cisco mesh networking architecture, access points are classified into two primary roles: Root Access Points (RAP) and Mesh Access Points (MAP). A RAP is an access point that maintains a wired Ethernet backhaul connection back to the network infrastructure, while a MAP operates wirelessly, relying on mesh backlinks to upstream RAPs. When an engineer needs to change an AP mode - such as switching to bridge mode to extend the mesh - the AP role must first be defined correctly. The AP must be designated as a RAP before any mode-level configuration changes are applied. This sequencing is critical because the AP role defines the fundamental backhaul path; changing the mode without first establishing the role results in misconfiguration and potential connectivity loss. The RAP communicates directly with the wired infrastructure via its Ethernet port, making it the gateway for all downstream MAPs in the mesh topology. Options A (monitor), C (bridge), and D (local) refer to AP modes, not roles, and cannot be configured until the role is properly defined.
