Option B is the only system profile that aligns with the Webex Contact Center Desktop WebRTC requirements shown in the exhibit. Cisco's desktop system requirements identify supported browsers and agent device models for calling, including Webex Calling desktop/app computer audio and WebRTC handling from Agent Desktop. A practical WebRTC station must have sufficient bandwidth, a supported operating system and browser, and browser settings that do not block required desktop behavior. Option A is weak because the 384 Kbps bandwidth value is below the practical WebRTC threshold shown by the comparison choices. Option C explicitly disables JavaScript, which prevents the browser-based desktop and WebRTC interaction logic from functioning properly. Option D uses a virtual desktop infrastructure condition, which is not the straightforward supported physical workstation profile presented by the question. Option B provides Windows 11, Chrome, physical host type, adequate bandwidth, a medium security level, and disabled pop-up blocking, making it the compliant choice.

The registration refresh interval is derived from the expires value multiplied by the refresh ratio. In Cisco IOS XE Local Gateway configuration for Webex Calling, the registrar command commonly uses an expires value and a refresh-ratio. With expires 240 and refresh-ratio 50, the gateway refreshes registration at 50 percent of 240 seconds, which is 120 seconds, or exactly two minutes. Option B uses refresh-time, which is not the documented parameter used in the provided command style. Option C would refresh at 60 seconds because 50 percent of 120 is 60. Option D would refresh at 150 seconds because 50 percent of 300 is 150. The correct answer is therefore the command that sets expires to 240 with refresh-ratio 50 over TLS using the sips scheme. This aligns with Cisco's registration-based Local Gateway model, where the SBC must keep SIP registration active toward Webex Calling.
