Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q39-Q44):NEW QUESTION # 39
An engineer deployed a Cisco ThousandEyes Enterprise Agent on a Meraki MX to monitor a critical SaaS application. Which kind of monitoring has the engineer set up?
A. active monitoring
B. server monitoring
C. agentless monitoring
D. passive monitoring
Answer: A
Explanation:
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)curriculum, understanding the distinction between different monitoring methodologies is fundamental to architecting an effective assurance strategy. When an engineer deploys aThousandEyes Enterprise Agenton a Meraki MX appliance, they are implementingactive monitoring.
Active monitoring, as defined in standard network assurance frameworks like RFC 7799, involves the generation of synthetic traffic or "probes" that are sent across the network to a specific destination. These probes, which can utilize protocols such as ICMP, TCP, or HTTP/S, simulate real user transactions to measure performance metrics including latency, packet loss, jitter, and path visualization. The Enterprise Agent acts as a dedicated vantage point, executing these tests at scheduled intervals to provide a proactive baseline of network and application health. This allows the engineer to identify performance degradation or outages even when no real users are actively using the application, ensuring that issues are detected before they impact the business.
It is important to contrast this withpassive monitoring(Option B). In the Meraki ecosystem,Meraki Insight (MI)natively performs passive monitoring by observing and analyzing actual user traffic flows (HTTP/S data) as they traverse the MX appliance without injecting additional traffic. While passive monitoring is excellent for understanding real-world user experience and server response times, it relies on existing traffic and cannot provide hop-by-hop path visualization across the Internet in the same way active synthetic probing does.
By integrating the ThousandEyes Enterprise Agent-which runs as a containerized service within the MX architecture-the engineer gains the benefits of active monitoring directly from the branch edge. This eliminates the need for separate hardware and provides deep, "outside-in" and "inside-out" visibility into SaaS application performance. Therefore, the deployment of a ThousandEyes agent explicitly enablesactive monitoring(Option A) to supplement the native passive capabilities of the Meraki platform.
NEW QUESTION # 40
What aspect of network performance is typically monitored using alert rules related to congestion?
A. DNS resolution speed
B. Packet loss
C. Network latency
D. Server response time
Answer: B
Explanation:
Packet loss is typically monitored using alert rules related to congestion to detect and address network performance issues caused by network congestion and packet drops.
NEW QUESTION # 41
What feature does Thousand Eyes WAN Insights provide to enhance network troubleshooting?
A. Real-time traffic visualization
B. End-to-end encryption
C. Machine learning algorithms
D. Predictive analytics
Answer: A
Explanation:
WAN Insights offers real-time traffic visualization to facilitate network troubleshooting and performance optimization.
NEW QUESTION # 42
Why is it crucial to set alerting thresholds in network assurance?
A. To monitor real-time traffic
B. To trigger alerts based on predefined conditions
C. To optimize WAN performance
D. To generate automated reports
Answer: B
Explanation:
Setting alerting thresholds is crucial in network assurance to trigger alerts based on predefined conditions, enabling timely detection and response to network issues.
NEW QUESTION # 43
A network engineer deploys a ThousandEyes Docker agent on a switch using app-hosting. 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 app-hosting configuration. What is the next step to ensure the agent uses the proxy and appears online in the ThousandEyes portal?
A. No action required; the agent will pick up the configuration automatically
B. Restart the container using app-hosting stop appid agentname followed by app-hosting start appid agentname
C. Reinstall the agent using the app-hosting install command with the correct proxy settings
D. 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
Answer: D
Explanation:
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)implementation guide, the Cisco IOS XEApplication Hostinglifecycle is a critical concept for troubleshooting and configuration management. When an application environment variable-such as proxy settings-is modified in the app-hosting configuration, a simple restart of the container is insufficient.
The correct procedure involves moving the application back to theConfiguredstate before bringing it back to Running. This requires a four-step lifecycle execution (Option C):
* Stop:Terminates the current running instance of the container.
* Deactivate:Releases the hardware resources (CPU, Memory, Virtual Interfaces) and, crucially, detaches the previous runtime configuration.
* Activate:Re-allocates the resources andinjects the new configuration parameters(including the updated proxy settings) into the container's environment.
* Start:Initiates the container with the newly applied configuration.
Without thedeactivate/activatesequence, the container will continue to use the environment variables present at the time of its initial activation, causing the agent to remain offline as it fails to reach the ThousandEyes portal without the proxy.Reinstalling(Option B) is an unnecessary and time-consuming step that involves re- downloading or re-copying the image, whileNo action(Option D) will result in no change to the agent's connectivity status.
