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.

A Web Chat widget that is visible in configuration but does not load on the company website commonly points to an asset-domain mismatch. Cisco Webex Connect live chat assets require the website domain to be configured for the asset so the platform can validate where the widget is embedded. The exhibit shows the browser-side failure after widget code is implemented, which is consistent with the site domain not matching the domain configured for the Web Chat Asset. Missing Webex Connect flow configuration usually causes chat handling or routing failures after a chat is initiated, not the widget failing to load. A firewall block to a widget domain is possible in the real world, but the question says the engineer sees output in the browser while investigating Webex Contact Center, and the Cisco configuration control involved is the website domain on the asset. Content Security Policy allow-listing in Webex Contact Center is for desktop/embedded content behavior, not the primary asset-domain validation for web chat loading.

The Resolve Conversation node is a Webex CC Task/Engage integration node that depends on valid node authorization in Webex Connect. Cisco's Webex Connect documentation states that client applications such as Webex Connect must provide a valid access token to use Cisco Webex Contact Center and Webex Engage APIs, and that the token is generated from the configured node runtime authorization. If the Resolve Conversation node fails because it cannot call the Webex Contact Center integration properly, the administrator must authorize the Webex CC Task integration in Webex Connect with valid credentials. Changing the administrator password does not directly authorize the node runtime. Agent credentials are irrelevant because the flow node is running as an integration, not as an agent desktop session. A connector under Webex Contact Center integrations may be needed for some external API use cases, but the failing node shown is part of the pre-built Webex Connect/WxCC task authorization path.

SMS-based one-time passcode authentication requires generating the passcode and sending it to the user over SMS. Webex Connect includes a Generate OTP node for creating the random passcode and an SMS node for delivering the generated value to the customer's mobile number. Those two nodes form the minimum authentication workflow. A Profile node can retrieve or update customer profile information but does not generate or deliver the passcode. A Data Parser node can parse structured responses, which is useful after API calls, but it is not required to create and transmit an OTP. An Evaluate node can compare the customer's submitted passcode to the stored/generated value later in the flow, but the question asks which two nodes are needed to implement authentication via SMS using a randomly generated passcode. The foundational nodes are Generate OTP and SMS. Reference: Webex Connect Help, Generate OTP node; SMS Node; Webex Connect flow builder documentation.

The Webex App inside Agent Desktop is controlled through the desktop layout JSON, not merely by installing the Webex App separately. Cisco documentation for supervisor and desktop features points administrators to the webexConfigured setting in the Webex Contact Center desktop layout. The layout also uses the AgentX Webex component identifier to render the embedded Webex application area. That is why the two required parameter combinations are the desktopChatApp object with webexConfigured set to true and the component value agentx-webex. The value webex-app is not the documented component name for this layout object. A generic webexAppEnabled Boolean or webexApp enabled object may look plausible, but it is not the required JSON pattern in the Cisco desktop layout schema. The result is practical: if either the correct component or the webexConfigured flag is absent, the embedded Webex App will not display in Agent Desktop for agent-to-agent, supervisor, or SME collaboration.
