Cisco 350-101 Dumps Questions Answers

Central Web Authentication is the correct design for an open guest SSID that redirects users to a captive portal before allowing network access. Cisco describes CWA as a guest-redirection method where the redirect URL and redirect ACL are centrally controlled and communicated to the WLC through RADIUS, with the external authentication system handling the login workflow. On a Catalyst 9800 WLAN, Cisco’s configuration flow for Central Web Authentication requires AAA/ACL configuration, including the AAA server list and an ACL tied to the WLAN so client access can be controlled before and after authentication.

Option D is the only answer that satisfies all requirements: captive portal redirection, post-authentication restriction to Internet-only access, and policy enforcement through ACLs. VLAN-level segmentation is implemented through the WLAN policy profile, which maps guest clients to the guest VLAN rather than the staff VLAN. WPA2-PSK is invalid because the guest SSID must not require a password. A local web server alone does not enforce Internet-only authorization or staff-network isolation. mDNS is unrelated to captive portal authentication or guest segmentation.

The correct answer isreduction of co-channel interference. AI-RRM in Cisco Catalyst Center is designed for RF optimization, not IP addressing, software scheduling, or user identity classification. Cisco describes AI-enhanced RRM as applying artificial intelligence and machine learning to optimize RF environments and automate/adapt RF parameter tuning for Cisco wireless networks. This is directly tied to operational RF outcomes such as improved channel planning, transmit power behavior, channel width decisions, and better spectrum utilization.

Co-channel interference occurs when multiple AP radios operate on the same channel within hearing range, forcing devices to share airtime and increasing contention. AI-RRM uses telemetry, analytics, and learned RF behavior to recommend or apply more optimal RF configurations. Cisco specifically states that AI-enhanced RRM optimization can produce improvements such as up to a40 percent reduction in co-channel interferenceand SNR gains for wireless clients. Cisco’s AI-RRM deployment guidance also identifies AP radio distribution and utilization analysis as critical for minimizing co-channel interference and optimizing wireless performance.

Therefore, option B is the only operational outcome aligned with AI-RRM’s purpose. Reference topic:Automation and AI — Cisco Catalyst Center AI-RRM, RF analytics, RRM automation, channel optimization, and wireless AIOps.

An RTS frame is an 802.11control frameused in the Request to Send/Clear to Send exchange. Cisco identifies RTS as a Request to Send frame and explains that 802.11 control frames assist in delivering data frames between stations. Cisco further states that the RTS/CTS function is optional, helps reduce collisions when hidden stations are associated to the same access point, and that a station sends an RTS frame as the first phase before transmitting a data frame.

Therefore, option B is correct because the RTS frame requests access to the wireless medium before data transmission. If the receiving station or AP replies with CTS, nearby stations defer transmission based on the duration information, reducing collision probability. This is especially relevant in hidden-node environments where two clients can hear the AP but cannot hear each other. Option A refers to RF spectral-mask compliance, which is a physical-layer regulatory concept. Option C confuses NAV behavior with roaming; RTS/CTS may influence virtual carrier sensing, not client roaming updates. Option D is unrelated because frame compression is not an RTS function.
