質問 # 70
Refer to the exhibit. A network administrator is working on a WLC to enable user access for employee tablets using PEAP-MSCHAPv2 with a RADIUS backend. The administrator verifies the external authentication configuration and plans to test network connectivity. Which code snippet must be added to the configuration for the WLC to support authentication with an external server?
正解：B
解説：
The missing command is radius server external-radius. On a Catalyst 9800 WLC, the external RADIUS server object must be declared first with radius server <server-name>. The following lines, address ipv4 10.10.10.100 auth-port 1812 acct-port 1813 and key radiuskey, are subcommands entered under that RADIUS server configuration mode. Cisco's Catalyst 9800
802.1X configuration workflow starts by declaring the RADIUS server, then adding it to a RADIUS server group, then creating the authentication method list, and finally mapping that list to the WLAN. Cisco's configuration guide example uses the same IOS XE structure: radius server
<name>, followed by address ipv4 ... auth- port 1812 acct-port 1813 and key ....
The server group later references server name external-radius, so the RADIUS server object must be named external-radius exactly. Option C would incorrectly create a server named RADIUS-GRP, which is already the AAA server group name, not the RADIUS server object.
Options B and D are invalid IOS XE syntax. PEAP-MSCHAPv2 itself is handled through the
802.1X/EAP exchange with the RADIUS server; the WLC acts as the authenticator and forwards authentication requests through the configured AAA method list.

What does a high SNR value result in?
正解：A
解説：
Signal-to-Noise Ratio (SNR) is a critical metric in wireless networking that quantifies the relationship between the received signal power and the background noise. A higher SNR indicates that the signal strength is significantly stronger than the noise level, which directly impacts the quality and reliability of wireless communication. When SNR is high, the receiver can more accurately decode transmitted frames, leading to fewer errors, reduced retransmissions, and improved data integrity. This results in more consistent throughput and better overall performance of wireless clients, especially in environments with high client density or potential sources of interference. Conversely, a low SNR increases susceptibility to multipath distortion, frame loss, and degraded network performance. Option C correctly identifies the outcome of a high SNR:
enhanced data integrity with fewer errors. Option A is incorrect because multipath distortion is primarily influenced by environmental reflections, not directly by SNR. Option B refers to antenna design and MIMO techniques, which affect directional gain and spatial streams but are independent of SNR measurement.
Option D is unrelated to SNR, as output frequency ranges are set by regulatory standards and hardware capabilities rather than signal-to-noise conditions. Cisco Wireless Core Technologies emphasizes monitoring SNR to optimize RF planning, AP placement, and client experience in enterprise wireless networks.
Reference topics:RF Fundamentals - SNR, signal quality, wireless performance, error rate, enterprise Wi-Fi.
質問 # 72
In an RF environment, what does high interference result in?
正解：B
解説：
High interference in a wireless RF environment disrupts the predictable behavior of 802.11 channels. Interference comes from co-channel devices, neighboring APs, non-Wi-Fi sources like microwave ovens, cordless phones, or other electronic equipment operating in the same frequency band. When interference is present, the channel experiences fluctuating noise levels, increased frame collisions, and packet loss, all of which lead to inconsistent channel performance.
This inconsistency manifests as variable throughput, increased retransmissions, and irregular latency, directly impacting both client experience and AP scheduling decisions. While frame aggregation may fail under interference, the primary and systemic effect is the variability in channel quality, not the failure of aggregation alone. Scheduled contention access (option C) is an intentional protocol mechanism of EDCA or TXOP scheduling, which operates independently of interference levels. Extended coverage patterns (option D) are the result of antenna design or AP placement, not RF interference.
Cisco's Wireless Design Guide emphasizes that RF interference results in erratic channel behavior, requiring careful channel planning, power adjustment, and spectrum analysis using tools such as Cisco DNA Spaces or Spectrum Expert to restore consistent performance.
質問 # 73
A Catalyst 9800 controller deployment requires seamless mobility across multiple controllers in the same mobility domain. Which feature enables this capability?
正解：C
解説：
Mobility groups allow wireless clients to roam seamlessly between controllers without losing connectivity or session information. Controllers exchange mobility data to preserve client state during roaming events. AVC and Hyperlocation provide analytics and location services rather than inter-controller mobility support.
質問 # 74
Refer to the exhibit. An engineer must configure wireless guest networking for a deployment at site A, which requires support for guest VLAN assignment and assignment for wlan guest- network 20. The controller will provide network segregation and restrict access to internal resources. Based on the configuration commands, which action meets the requirements?
正解：A
解説：
The exhibit creates WLAN profile guest-network with WLAN ID 20 and enables web authentication, but it does not yet define the client VLAN or bind the WLAN to a deployable policy.
On Catalyst 9800 controllers, the WLAN profile defines SSID and wireless/security characteristics, while the policy profile defines client-facing network policy, including VLAN assignment, AAA, ACLs, and switching behavior. Cisco's web authentication configuration guide states that the policy profile specifies client VLAN, AAA, ACLs, timeout settings, and related policy, and the VLAN is assigned under the policy profile.
The second required object is the policy tag, because a policy tag maps the WLAN profile to the policy profile. Cisco also notes that the default policy tag automatically maps only WLAN IDs 1 through 16; WLAN ID 17 or higher cannot use that default mapping. Since this WLAN is ID 20, a custom policy tag mapping is required. Mesh bridging, STP, AP group naming, or physical- interface isolation do not complete the Catalyst 9800 WLAN-to-VLAN policy model.
