Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q31-Q36):

NEW QUESTION # 31
What is the primary purpose of synthetic web tests in network assurance?

Answer: C

Explanation:
The primary purpose of synthetic web tests is to simulate user interactions with web applications, facilitating performance monitoring and optimization in network assurance.


NEW QUESTION # 32
Which Thousand Eyes test is specifically designed to assess the performance of DNS resolution?

Answer: D

Explanation:
The DNS test in Thousand Eyes is specifically designed to assess the performance of DNS resolution, identifying latency and response time issues in network assurance.


NEW QUESTION # 33
For managing and securing user endpoints in a distributed enterprise, which Cisco solution would you employ?

Answer: A


NEW QUESTION # 34
An architect needs to measure end-user experience for internal web applications and SaaS products. Which ThousandEyes agent should be deployed for this purpose?

Answer: D

Explanation:
In the context of Designing and Implementing Enterprise Network Assurance (300-445 ENNA), measuring the "lived experience" of an end-user requires data collection from the actual device being used to access the services. Unlike server-side or infrastructure-side monitoring, user experience (UX) monitoring must account for local variables like Wi-Fi signal quality, CPU/memory usage, and browser-level performance.
The Endpoint Agent (Option D) is the correct choice for this architecture. It is a lightweight software service installed directly on Windows or macOS workstations, as well as RoomOS devices. The Endpoint Agent provides a dual-monitoring approach: Real User Monitoring (RUM) and Scheduled Synthetic Tests. RUM captures actual browser sessions to SaaS (e.g., Salesforce, Microsoft 365) or internal apps, providing a "Experience Score" and a detailed waterfall view of page load components. Simultaneously, the agent can run background synthetic network tests to measure latency and path visualization from the user's specific location, whether they are in a branch office, at home on a VPN, or in a coffee shop.


NEW QUESTION # 35
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.
