質問 # 88
An onsite engineer is working to connect devices to the wireless network using central switching in a corporate environment. Security protocols and network-specific settings must be configured as per enterprise policy. After the initial wireless settings are applied on an iOS tablet, the engineer must ensure that VLAN ID 10 is assigned on the client device to complete a successful enterprise Wi-Fi connection. Which action meets this requirement?
正解：D
解説：
In a centrally switched deployment, the WLAN traffic is tunneled via CAPWAP from the AP to the WLC, where VLAN assignment occurs. To ensure that client devices are placed into the correct VLAN (in this case, VLAN 10), the WLAN policy profile must define the VLAN mapping. This allows the WLC to tag client traffic appropriately when forwarding to the upstream switch. Option C is correct because it configures the WLAN profile (policy profile) with VLAN 10, ensuring all clients associating with the WLAN are mapped to the proper VLAN automatically.

In an RF environment, what does high interference result in?
正解：B
解説：
The correct answer is B. inconsistent channel performance . In WLAN RF design, interference is unwanted RF energy in the same or adjacent frequency space that reduces the usable quality of a channel. Cisco defines interference as unwanted RF signals in the same frequency band that can cause degradation or loss of service.
When interference increases, the channel becomes less predictable: clients and APs experience higher contention, more retries, lower modulation rates, reduced throughput, and unstable latency.
Cisco also notes that overlapping channels can create RF interference, leading to connectivity issues and poor throughput. In co-channel interference scenarios, adjacent radios on the same channel interfere with network performance through collisions or excessive CSMA deferrals, degrading WLAN performance. This directly maps to inconsistent channel performance because the channel may appear usable at one moment and congested or impaired the next.
The other answers are not the best operational result. Frame aggregation may be impacted indirectly, but it is not the primary RF-level outcome. Scheduled contention access is not caused by interference. Extended coverage patterns are related to antenna gain, transmit power, and propagation, not high interference.

質問 # 90
Which solution enables a seamless user experience when roaming in a wireless network?
正解：D
解説：
Fast transition is the correct solution because it refers to IEEE 802.11r Fast BSS Transition, which reduces the authentication delay when a wireless client roams from one AP to another.
Cisco describes 802.11r Fast Transition as a feature for seamless wireless roaming and states that, after configuration, the WLAN supports faster client roaming between access points. Cisco's Catalyst 9800 roaming documentation also identifies 802.11r as the mechanism focused on seamless transition between APs, while 802.11k and 802.11v assist with neighbor reporting and network-assisted roaming decisions.
The core advantage is that key negotiation and authentication preparation occur before or during the roam, reducing the interruption experienced by latency-sensitive applications such as voice, video, collaboration tools, and real-time enterprise applications. Static VLAN policy only controls segmentation and does not accelerate roaming. Optimized roaming can help discourage sticky clients from remaining associated to poor-quality APs, but it is not the primary fast-roam authentication mechanism. A redundant RF profile is not an 802.11 roaming solution.
質問 # 91 
Refer to the exhibit. A client authenticates via 802.1X against an ISE server that is configured to return a specific VLAN ID (VLAN 100) via an attribute value pair. However, the administrator notices that the client is placed in the wrong VLAN (VLAN 50). What must the administrator implement to resolve the issue?
正解：A
解説：
In this scenario, the client is placed in the wrong VLAN (VLAN 50) even though the ISE server is configured to assign VLAN 100. The key part of the issue is that the VLAN assignment returned by ISE is not being applied correctly.
Option A: "Configure the policy profile to allow ISE to override the VLAN."This is the correct answer. The policy profile on the Wireless LAN Controller (WLC) should be configured to allow the ISE server's VLAN assignment to override the locally configured VLAN settings on the WLC. Without this, the WLC might default to its pre-configured VLAN (VLAN 50) instead of the VLAN assigned by ISE (VLAN 100).
Option B: "Configure VLAN 100 as an SVI on the WLC."This option is unnecessary. While an SVI (Switched Virtual Interface) is required to route between VLANs, it is not the cause of the issue here. The problem is that the correct VLAN (VLAN 100) is not being applied to the client, not that the WLC lacks an SVI.
Option C: "Configure VLAN 100 on the trunk ports of the WLC."This option is also not relevant. The issue is not with trunking but with VLAN assignment from ISE. The trunking configuration ensures that VLANs are allowed across ports, but it does not address the client being placed in the wrong VLAN.
Option D: "Configure AAA VLAN enable on the WLAN."This option is not directly related to the issue.
While enabling AAA VLAN can allow for more dynamic VLAN assignments, the core issue is related to overriding the default VLAN setting from ISE, which is handled by configuring the policy profile on the WLC.
Therefore,Option Ais the correct solution, as it ensures the WLC will allow the ISE server's VLAN assignment to override the default VLAN on the WLC, resolving the issue of incorrect VLAN assignment.
質問 # 92
Refer to the exhibit. A network engineer is designing a Wi-Fi deployment for a high-density office environment. The engineer must select the appropriate channel plan to minimize co-channel interference (CCI) in the 2.4 GHz band. Which strategy is recommended to reduce CCI?
正解：A
解説：
In the 2.4 GHz band, IEEE 802.11b/g/n Wi-Fi uses channels that are 20 MHz wide but only partially non-overlapping. Cisco Wireless design guides recommend using only non-overlapping channels to prevent co-channel interference (CCI), which occurs when adjacent APs transmit on overlapping frequencies and contend for airtime, resulting in reduced throughput and increased latency. The standard non-overlapping channels in North America are 1, 6, and 11. By carefully assigning these channels to adjacent access points, the RF designer ensures that no two neighboring APs share overlapping channels, thereby minimizing CCI and improving overall network performance.
