Cisco 300-830 Dumps

Option C is correct because it checks membership by comparing the selected queue_ID string to the id value in each dictionary in the queue_IDs list. The input structure says queue_ID is a string and queue_IDs is a list of dictionaries, with each dictionary containing an id key. A direct expression like agent_Queue in queue_List fails because it compares a string to whole dictionary objects, not to their id values. A loop that sets rtt_Enabled to False inside the else branch can also produce wrong results because a nonmatching later dictionary can overwrite a previous match. The Python any() expression is the cleanest correct logic: it returns True if at least one dictionary has an id equal to the selected queue. The function then writes rtt_Enabled into response.data for the flow to consume before deciding whether to start the media stream.

Cisco documents two Local Gateway trunking models for Webex Calling: registration-based trunks and certificate-based trunks. A registration-based trunk has the local gateway maintain SIP registration toward Webex Calling, and the signaling relationship is established through that registration. Cisco's trunk and dial plan documentation describes this model as an implicit connection based on the gateway's registration. A certificate-based trunk uses mutual TLS and certificate trust to authenticate signaling without SIP registration in the same way. These are the formal trunking choices used when integrating on-premises voice infrastructure with Webex Calling and, by extension, supporting Webex Contact Center telephony designs that use Local Gateway. DNS-based trunks are not a Cisco trunking model name in this context. PSTN trunks and enterprise trunks are generic or design descriptions, not the two Local Gateway models. For 300-830, the key is recognizing the official Webex Calling trunk model terminology.

Webex Contact Center APIs use OAuth 2.0 for authentication and authorization. Cisco's developer documentation for Webex and Webex Contact Center describes integrations as the mechanism used to request permission and obtain access tokens for API calls, using the OAuth 2.0 authorization framework rather than static API keys or basic HTTP authentication. OAuth 2.0 gives the platform scoped access control, token issuance, and administrative consent behavior appropriate for enterprise automation. Mutual TLS may be used in specific transport-security or trunking contexts, but it is not the authorization specification for normal Webex Contact Center REST APIs. Basic HTTP authentication would require sharing credentials directly with the client and does not match the Webex developer model. API key authentication is also not the supported authorization pattern for these Contact Center APIs. The typo in the original option has been corrected to OAuth 2.0.
