Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q24-Q29):

NEW QUESTION # 24
What is the primary purpose of implementing synthetic web tests?

Answer: A

Explanation:
The primary purpose of implementing synthetic web tests is to monitor web application performance, identifying issues such as latency and downtime proactively.


NEW QUESTION # 25
What is the primary function of a scripting agent in network assurance?

Answer: C

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


NEW QUESTION # 26
What is the first step in establishing a metric baseline for network performance analysis?

Answer: C

Explanation:
Defining key performance indicators (KPIs) is the initial step in setting a metric baseline for network performance analysis.


NEW QUESTION # 27
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.


NEW QUESTION # 28

Refer to the exhibit. An engineer set the default alert condition for the network alert rule, but NOC operators report that they are getting too many false-positive alerts. Which action reduces the noise while adhering to the company ' s operational requirements?

Answer: D


NEW QUESTION # 29
......
