Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q97-Q102):

NEW QUESTION # 97
Which integration type enables seamless data exchange between Cisco technologies and third-party ITSM platforms?

Answer: C

Explanation:
API integration enables seamless data exchange between Cisco technologies and third-party ITSM platforms, facilitating automation and interoperability in network assurance.


NEW QUESTION # 98
Users on remote sites are reporting voice issues, can you identify possible causes and next steps from the following exhibits?



Answer: C


NEW QUESTION # 99
A CPU utilization alert for Endpoint Agents is triggering too frequently, creating alert noise. Which of the following steps would help reduce the sensitivity of the alert rule? (Select two)

Answer: B,D

Explanation:
Alert fatigue is a major operational challenge in network assurance. To make a CPU utilization alert for Endpoint Agents less sensitive and reduce "noise," an engineer must implement statistical filters that ignore transient spikes or isolated events.
The two most effective methods are:
Increase the agent count (Option A): By requiring a higher number or percentage of agents to simultaneously exceed the threshold, the system ensures the alert represents a widespread environmental issue rather than a single user running a CPU-intensive background process.
Require more rounds of data (Option C): Instead of alerting on a single measurement (1 of 1 round), the engineer can configure the rule to require the threshold to be breached for multiple consecutive checks (e.g., 2 of 3 rounds). This filters out brief, non-impactful CPU spikes that occur naturally during OS updates or browser startups.


NEW QUESTION # 100
Which alert rule configuration affects the end-user experience by monitoring CPU utilization and connectivity types?

Answer: C

Explanation:
User experience alert rules affect the end-user experience by monitoring CPU utilization, connectivity types, and other factors impacting usability.


NEW QUESTION # 101
You are investigating intermittent failures in a ThousandEyes transaction test targeting a web application that uses Basic Authentication. The failures occur randomly across different agents and times of day. What steps would you take to troubleshoot and resolve the issue? (Select all that apply)

Answer: A,C,D

Explanation:
Troubleshooting intermittent performance issues is a core component of the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum. When a transaction test using Basic Authentication fails randomly, the engineer must employ a multi-layered diagnostic approach to determine if the fault lies with the credentials, the network path, or the application server.
The first step is to verify the correctness of credentials (Option B). Because Basic Authentication encodes credentials in the header, any change in user permissions or account lockouts will trigger immediate failures. Performing manual logins from various geographical locations helps rule out location-based access control lists (ACLs) or regional IdP sync issues.
The most data-rich diagnostic step is to analyze the ThousandEyes waterfall charts and HTTP response codes (Option C). The waterfall view allows the engineer to see if the failure happens during the initial 401 Unauthorized challenge or after the credentials are sent. If the charts show high "Wait Time" or 5xx errors, the issue is likely server-side latency or instability. If the "Connect Time" is high, the problem may be network-layer congestion.
Finally, if the telemetry indicates that the network path is healthy but the server is intermittently returning errors or timing out, the engineer should contact the web application vendor (Option D).
Providing the vendor with the specific ThousandEyes "Share Link" allows them to see the exact same packet-level and browser-level data, proving that the issue is not with the client's network but with the server-side infrastructure. Disabling authentication (Option A) is not a valid troubleshooting step for a test designed specifically to monitor an authenticated workflow.
