Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q62-Q67):

NEW QUESTION # 62
Users at a remote corporate site (identified as s30 in the exhibit) are experiencing issues with a critical Enterprise Application hosted in the Data Center. The site connects to the central campus through an MPLS network.

The following exhibits show the network status before and after the issue began. Based on the information presented, what is the most likely cause of the problem and what actions would you take next as a Network Operations Engineer?

A. Check the routing tables on the MPLS network devices for any recent changes.
B. Review the bandwidth utilization at this site.
C. Reach out to the team that owns the Enterprise Application and have the server reviewed.
D. Escalate to the transmission media team and have the optic fiber between 10.84.30.1 and 10.87.16.53 checked.

Answer: D

NEW QUESTION # 63
What is a primary advantage of passive monitoring over active monitoring?

A. Passive monitoring can provide real-time data on network performance without adding traffic to the network.
B. Passive monitoring can directly measure the performance of specific network services or protocols.
C. Passive monitoring can measure the network's performance under synthetic conditions.
D. Passive monitoring allows for the generation of test traffic to simulate user behavior.

Answer: A

Explanation:
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) architecture, a critical design consideration is the impact of the monitoring solution on the production environment. The primary advantage of passive monitoring (Option B) is its non-intrusive nature; it provides insights into network performance and traffic composition without injecting additional
"synthetic" overhead into the data plane.
Passive techniques--such as Cisco Meraki Insight (MI), NetFlow, and SNMP--rely on the telemetry generated by existing user traffic or the device's own control plane. For example, Meraki Insight analyzes HTTP/S flows as they naturally pass through a Meraki MX appliance to derive application performance scores, rather than sending separate probes. This ensures that the monitoring tool itself does not consume bandwidth or contribute to network congestion, which is particularly vital in bandwidth-constrained branch environments or on high-utilization links.

NEW QUESTION # 64
Refer to the exhibit. For over an hour during the workday, users trying to join Webex meetings experienced significant issues joining and creating meeting invites. What is a reason for this issue?

A. The Cisco ThousandEyes agent is sending an incorrect payload to the destination.
B. The network is congested.
C. There is end-to-end network loss.
D. Errors are occurring in the application server.

Answer: D

Explanation:
The waterfall view shows HTTP 502 errors returned from webex.com.
All network phases (DNS, Connect, SSL, Send, Receive) are healthy, meaning the network path is not the cause.
A 502 response indicates a server-side application problem, confirming that the Webex application backend was generating errors during the affected period.

NEW QUESTION # 65
What capability does Thousand Eyes WAN Insights offer for network optimization?

A. Optimizing server performance
B. Predicting security threats
C. Analyzing WAN traffic
D. Enhancing endpoint security

Answer: C

Explanation:
Thousand Eyes WAN Insights offers the capability to analyze WAN traffic, identifying bottlenecks and optimizing network performance for improved user experience in network assurance.

NEW QUESTION # 66
What is the primary purpose of implementing synthetic web tests?

A. Testing network infrastructure
B. Analyzing browser waterfalls
C. Assessing security vulnerabilities
D. Monitoring web application performance

Answer: D

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