Designing and Implementing Enterprise Network Assurance(300-445 ENNA) 300-445 Exam Questions with Experts Answers Updated Recently

For theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)exam, monitoring remote workforces requires a strategy that captures both the user's local environment and the regional internet health. In a scenario involving Cisco AnyConnect VPN, the "last mile" connectivity of the employee is often the most significant variable in application performance.

Utilizing the ThousandEyes Endpoint Agent(Option D) is the most effective way to monitor this environment. Because the agent resides directly on the remote employee's machine, it can monitor the performance of the web application both "inside" and "outside" the VPN tunnel. It provides visibility into the local Wi-Fi signal strength, the health of the AnyConnect client, and the latency experienced as traffic traverses the VPN headend. This allows engineers to differentiate between a slow home internet connection and an issue with the VPN concentrator.

Deploying ThousandEyes Cloud Agents(Option A) serves as a critical baseline. By running tests from Cloud Agents in the same regions as the remote employees, the engineer can determine if the "internet" in that region is healthy. If a Cloud Agent in London shows a perfect response time while an Endpoint Agent in London shows high latency, the engineer can immediately isolate the problem to the user's specific setup or the VPN path, rather than a regional ISP outage.

Other options are less suitable for monitoring theremote employee's experience:

AppDynamics (Option B)provides server-side code visibility but cannot see the user's home Wi-Fi or local network path.

Enterprise Agents on the VPN concentrator (Option C)can monitor the pathfromthe data center to the app, but they cannot see the path from theuserto the concentrator.

Enterprise Agents in the data center (Option E)provide an "inside-out" view of the app's health but miss the entire remote access experience.
