B. One of the DOM elements cannot be found in the server

C. The request timed out waiting for the server to respond

D. There is a misconfiguration in the application server

What is an important consideration when choosing a time period for collecting data to establish a baseline for interface utilization on a critical network link?

A. Selecting the time period with the lowest network traffic volume.

B. Ensuring the time period aligns with the organization's financial year.

C. Capturing both peak and off-peak traffic patterns for a representative view.

D. Limiting the time period to minimize the amount of data that needs to be analyzed.

An architect needs to analyze network path metrics from their internal network, specifically from the access layer to a cloud-hosted web server.1 Which ThousandEyes agent is most appropriate for this task?

A. Synthetic Agent

B. Enterprise Agent

C. Cloud Agent

D. Endpoint Agent

You're analyzing NetFlow data for a network supporting voice and video traffic. The data shows consistent spikes in delay and jitter during peak hours. Which optimization would you recommend?

A. Implement a complete QoS redesign

B. Increase bandwidth on all network links

C. Tune the existing QoS configuration to prioritize voice and video traffic

D. Replace all network hardware with newer models

A network engineer deploys a ThousandEyes Docker agent on a switch using apphosting. 7 The agent needs to communicate through a proxy server, but this configuration was missed during the initial deployment. The engineer adds the proxy settings to the apphosting configuration. What is the next step to ensure the agent uses the proxy and appears online in the ThousandEyes portal?

A. Restart the container using app-hosting stop appid agentname followed by app-hosting start appid agentname

B. Reinstall the agent using the app-hosting install command with the correct proxy settings

C. Execute the full agent lifecycle: app-hosting stop appid agentname, app-hosting deactivate appid agentname, app-hosting activate appid agentname, app-hosting start appid agentname

D. No action required; the agent will pick up the configuration automatically

The Endpoint stopped appearing online after it was moved to another network. The customer reviewed the endpoint logs but did not identify anything suspicious. The customer also confirmed that the endpoint was online on the old network, and the new network is fully operational. Other endpoints that were moved to the new network are also online. Since the new network is small, the admin is using static IP assignment. What is the best way to bring the endpoint online?

A. It may be an issue with the lack of space in the new network. The endpoint should be moved back to the old network.

B. The endpoint agent should be reinstalled to come online. This always helps.

C. The endpoint will automatically come online in 10-15 minutes, no action is needed.

D. Endpoint IP settings must be checked along with connectivity to c1.eb.thousandeyes.com.

Refer to the exhibit.

A. opentelemetry

B. custom-webhook

C. push-api

D. poll-api
