                                        Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q49-Q54):

                                        NEW QUESTION # 49
                                        A company is noticing sporadic slowdowns in their web application performance, impacting user experience.
                                        They suspect it might be related to high CPU utilization on employee laptops, potentially caused by background processes. Which ThousandEyes alert type and condition combination would be most effective in identifying if endpoint CPU performance is contributing to this issue?

                                        Answer: B

                                        Explanation:
                                        In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)curriculum, isolating performance issues on end-user machines requires a combination of application-layer experience data and local system telemetry. When an architect suspects that local hardware constraints, such as high CPU usage, are degrading the digital experience, theEndpoint Agentis the required vantage point.
                                        The correct combination isReal User Tests > Endpoint, CPU utilization # %(Option C). This alert configuration is effective for several reasons:
                                        * Targeted Visibility:It directly monitors the user's device (Endpoint) where the hardware bottleneck is suspected to reside.
                                        * Real-Time Context:By utilizingReal User Tests (RUM), the agent gathers performance data during actual user activity (e.g., browsing the web application). This ensures that the CPU spikes are correlated with active application usage, providing a representative view of the impact on experience.
                                        * Threshold Alerting:The condition monitors for CPU utilization exceeding a defined percentage threshold (# %). This allows IT teams to be notified only when the CPU load reaches problematic levels that are known to cause application sluggishness or browser "freezing".
                                        Alternative options are less effective for this specific troubleshooting goal:
                                        * Option A:Monitors network loss, which would not identify a local CPU bottleneck.
                                        * Option B:Monitors path length (hops), which is a routing metric irrelevant to local hardware performance.
                                        * Option D:Monitors memory load during scheduled tests. While memory is a factor, the specific suspicion in this scenario is CPU utilization, and scheduled tests do not always capture the same load impact as a real user interacting with the browser.


                                        NEW QUESTION # 50
                                        Employees and customers of a retail company are experiencing performance issues with the store website, such as slowness during the login process or failure when adding items to the cart.
                                        Which test type is the most useful for identifying the root cause of these problems?

                                        Answer: B

                                        Explanation:
                                        In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, selecting the appropriate test type is essential for isolating performance bottlenecks in complex web applications. When users report issues with specific multi-step workflows--such as logging into a portal or interacting with a shopping cart--the Transaction test type (Option C) is the most effective tool.


                                        NEW QUESTION # 51
                                        An engineer configures an alert rule to trigger when an interface on a network switch goes down or when the amount of incoming traffic exceeds half the interface link speed. Drag and drop the options from the bottom onto the boxes in the alert rule configuration screen. Not all options are used.

                                        Answer:

                                        How do scripting agents contribute to network assurance?

                                        Answer: A

                                        Explanation:
                                        Scripting agents automate network tasks to enhance operational efficiency and ensure consistent network performance.


                                        NEW QUESTION # 53
                                        When selecting a Cisco network assurance platform, what factor should be prioritized for efficient network troubleshooting?

                                        Answer: D

                                        Explanation:
                                        Prioritizing alerting mechanisms is crucial when selecting a Cisco network assurance platform for efficient network troubleshooting and issue resolution.
