Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q32-Q37):

NEW QUESTION # 32
When configuring alert rules for end-user experience monitoring, what metric is commonly monitored to assess browser behavior?

Answer: D

Explanation:
Page load time is commonly monitored when configuring alert rules for end-user experience monitoring to assess browser behavior. Page load time measures the time taken for a web page to load completely in the user's browser, including downloading HTML, CSS, JavaScript, and media assets, providing insights into browser performance, responsiveness, and user experience.


NEW QUESTION # 33
Users on remote sites are reporting voice issues, can you identify possible causes and next steps from the following exhibits?



Answer: B


NEW QUESTION # 34
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: C

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 # 35
An engineer configures an alert on the Cisco Meraki cloud platform that meets these requirements:
The alert must monitor the traffic related to cisco.com on a per-flow basis.
The alert must upload the data to Cisco Meraki for further analysis.
Which type of alert must be used to meet these criteria?

Answer: D


NEW QUESTION # 36
What type of alert rule configuration is used to monitor VPN connectivity issues affecting the end-user experience?

Answer: A

Explanation:
Connectivity-based rules are used to monitor VPN connectivity issues affecting the end-user experience by setting thresholds for VPN connection establishment times, packet loss rates, and latency to detect connectivity failures, disruptions, or degradation and trigger alerts for immediate investigation and resolution.
