NEW QUESTION # 50
An engineer is trying to configure a Page Load test and is trying to assign the east1-agent-1 to run it, but cannot see that agent listed. What is the reason that the designated agent does not appear?
Answer: B
Explanation:
In the framework of Designing and Implementing Enterprise Network Assurance (300-445 ENNA), selecting the appropriate agent for specific test types is a critical configuration step. The ThousandEyes platform utilizes different agent binaries and capabilities depending on the underlying hardware and software environment. Specifically, Page Load tests and Transaction tests require the agent to have a browser engine (Chromium) installed and functional to render web content and measure DOM-related metrics.
According to the ENNA implementation guidelines, not all Enterprise Agents support these browser- based tests. The exhibit displays a "New Test" configuration screen where the engineer is searching for "east1-agent-1". While other agents like "west-2-ag-1" are visible, the designated agent is missing because it does not support Page load tests (Option D). This common occurrence happens when an Enterprise Agent is deployed on resource-constrained hardware-- such as certain Cisco Catalyst 9000 switches or Cisco ISR 4000 series routers--where the Chromium browser package is either not supported or has not been enabled due to memory and CPU limitations.
NEW QUESTION # 51
Refer to the exhibit. An engineer receives a P1 incident from an office that is experiencing issues with Microsoft Teams. What is the root cause of the issue?
Answer: D
NEW QUESTION # 52
The network team has deployed Webex RoomOS Endpoint Agents and integrated Webex Control Hub with ThousandEyes. The VoIP team wants to know which metrics they can collect from the Webex Control Hub view. Where does the VoIP team find the network data?
Answer: B
Explanation:
According to the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, the integration between ThousandEyes and Webex Control Hub provides a streamlined troubleshooting experience for collaboration services. For the VoIP team to access the specific ThousandEyes network telemetry--such as latency, loss, and jitter--they must navigate to the Network Path (Option B) section within the Troubleshooting tab of the Control Hub.
The Network Path visualization is a direct result of the ThousandEyes Endpoint Agent data being pulled into the Webex interface. When a user or RoomOS device experiences poor audio or video quality during a meeting, the Control Hub's troubleshooting view displays a "Network Path" line under the participant's details. By clicking on this line, the VoIP team can see a hop-by-hop breakdown of the entire route from the collaboration device to the Webex media node. This view highlights specific hops where performance is "Poor" (red), "Fair" (yellow), or "Good" (green) based on predefined thresholds for latency (>400ms) or loss (>5%).
NEW QUESTION # 53
Refer to the exhibit.
A network engineer is tasked with configuring an alert that will trigger if the HTTP server responds with a server error. What alert conditions should be configured to meet the specified requirements?
Answer: C
Explanation:
56
In theDesigning and Implement7ing Enterpr8ise Network Assurance (300-445 ENNA)framework, configuring effective alert rules is critical for distinguishing between standard network noise and actionable application-layer failures. ForWeb - HTTP Servertests, ThousandEyes allows engineers to monitor both network-level metrics (like Connect time) and application-level indicators (like HTTP response codes).
The requirement is to trigger an alert specifically when the HTTP server responds with aserver error. In the HTTP protocol, server errors are categorized as the5XXseries of status codes (e.g., 500 Internal Server Error,
503 Service Unavailable, 504 Gateway Timeout). To meet this requirement, the engineer must configure a location alert condition where theMetricis set toResponse Codeand the condition value isserver error(5XX) (Option D).
Reviewing the other options:
* Error type is any (Option A):While this would capture server errors, it would also trigger for 4XX client errors (like 404 Not Found) and network-layer timeouts, making it too broad for a specific "server error" requirement.
* Wait Time is Dynamic (Option B):This monitors the time-to-first-byte using statistical baselining.
While high wait times oftenprecede5XX errors, this condition only alerts on latency, not on the actual error code itself.
* Response Time (Option C):Similar to wait time, this monitors performance speed rather than the logical success or failure of the server's response.
By specifically selectingResponse Code: server error(5XX), the engineer ensures that the operations team is only notified when the application backend is experiencing a functional failure, rather than just a slow response or a client-side misconfiguration.
