問題 #43
A major corporation wants to migrate to Webex Contact Center but requires that the current PSTN carrier and enterprise PBX based agents be retained in its on-premises environment.
Which action must the engineer take to meet this requirement?
答案：A
解題說明：
A Local Gateway design is the correct migration pattern when the enterprise wants to retain an existing PSTN carrier and on-premises PBX-based agent environment. Cisco positions Local Gateway as the component that integrates the existing on-premises deployment with Webex Calling, allowing organizations to migrate at their own pace while continuing to use existing PSTN and call-control investments. In this design, an on-premises SBC, commonly Cisco Unified Border Element or another supported border element, routes calls between the enterprise environment and Webex Calling/Webex Contact Center. Porting DIDs to Cisco Calling Plan would replace the PSTN arrangement rather than retain it. Asking the PSTN carrier to forward all contact center numbers to Webex Calling may work for a simple design, but it does not retain PBX-based routing and agent connectivity in the same controlled way. The requirement is implementable, and Local Gateway is the documented method. Reference: Cisco Help, Get started with Local Gateway; Webex Contact Center Data Sheet.
問題 #44
A user has the agent role and plans to sign in to Cisco Webex Contact Center desktop.
Which system meets the requirements for WebRTC as the agent phone device?
A )
B )
C )
D )
答案：D
解題說明：
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.

問題 #45
A customer wants to enable the Real Time Transcription (RTT) feature only for specific queues. This feature is enabled by using the Start Media Stream node in Flow Designer, so the administrator decides to control the enablement using a function. The function must check two input variables: queue_ID for the selected agent queue (a string) and queue_IDs for the list of queues that require the RTT feature (a list of dictionaries, where each dictionary has an id key for the queue ID). The function returns a boolean variable rtt_Enabled to the flow, which indicates whether RTT should be enabled.
Which function is correct when using Python?
A )
B )
C )
D )
答案：C
解題說明：
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. Reference: Cisco Help, Build and manage flows with Flow Designer; Flow Designer function runtime documentation.
問題 #46
During troubleshooting, an engineer observes high packet loss affecting Webex meetings. Which symptom is MOST likely experienced by users?
答案：C
解題說明：
Packet loss directly impacts real-time media streams, causing symptoms such as choppy audio, robotic voice quality, frozen video, or one-way audio. Collaboration applications are highly sensitive to packet loss because RTP traffic depends on continuous packet delivery with minimal retransmission opportunities.
問題 #47
What are the two current default rate limits for a given client ID when Webex Contact Center APIs are protected with rate limiting? (Choose two.)
答案：A,E
解題說明：
Webex Contact Center API rate limiting is applied per client ID with default limits of 30 requests per second and 1800 requests per minute. These limits control both short burst traffic and sustained request volume for the client application.
