Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q99-Q104):

NEW QUESTION # 99
A corporation uses Cisco network devices. A network administrator must deploy a Cisco ThousandEyes Enterprise Agent to all corporate stores to monitor experience, but the administrator does not have servers or compute deployed. Which two agent deployment types would be the best fit for an edge retail location?
(Choose two.)

Answer: D,E


NEW QUESTION # 100
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?

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 # 101
Refer to the exhibit. Cisco ThousandEyes sent an alert that the bank website cannot be loaded in
10 seconds from the Sydney Cloud agent. What is the root cause of the website outage?


Answer: B

Explanation:
From the waterfall view, the critical delay occurs during the Receive phase of the large neo_background.jpg object:
- Receive time: 6472 ms
- Total load time: 7405 ms
- DNS, Connect, SSL, and Send times are normal.
A long Receive time indicates slow data transfer, not redirects, CPU issues, or missing objects.
This conclusively points to bandwidth throughput problems on the path between the Sydney Cloud agent and the bank site.


NEW QUESTION # 102
How do scripting agents contribute to network automation?

Answer: A

Explanation:
Scripting agents automate repetitive tasks to facilitate network automation and improve operational efficiency.


NEW QUESTION # 103
The following exhibit shows the Capacity Planning results for a router interface connected to an ISP, which provides a 1Gbps connection. Based on the evidence, which action is most likely to fix the observed behavior?

Answer: D

Explanation:
In the context ofDesigning and Implementing Enterprise Network Assurance (300-445 ENNA), capacity planning requires accurate baselining of interface bandwidth against its theoretical and provisioned limits.
AnalyzingExhibit 4.5 Question 4(image_79d4fc.jpg) reveals a significant discrepancy between the physical reality of the link and its configuration within the monitoring tool.
The exhibit displays a capacity planning dashboard with a calendar heatmap and traffic graphs. The heatmap for February through May shows a high frequency of "Severe" (red) utilization blocks. Looking at theEgress graph forTue May 07 2024, the traffic spikes clearly exceed 40.0 Mbps. Crucially, the dashboard indicates an
"Egress Capacity" of49.5 Mbpsand reports that the "Highest consumption" was 48.0 Mbps, representing97% of the available bandwidth.
However, the question states that the ISP provides a1 Gbps (1000 Mbps) connection. Since the actual traffic being sent is less than 50 Mbps, the link is nowhere near physical saturation. The "Severe" alerts and high utilization percentages are occurring only because the monitoring software (likely ThousandEyes or a similar NMS) is configured with aMaximum Capacityof only 49.5 Mbps for this interface. This misconfiguration causes the tool to calculate utilization based on a much smaller "pipe" than what actually exists, leading to false-positive alerts.
Therefore, the most likely action to fix this observed behavior is toreconfigure maximum capacity for the interface(Option B) to match the 1 Gbps specification.
* Option Ais unnecessary because the current link is only being utilized at ~5% of its 1 Gbps potential.
* Option Cis a restrictive policy change that is not justified given the actual available headroom.
* Option Dmight shift how data is displayed but will not fix the underlying mathematical error in utilization calculations.
