Cisco Designing and Implementing Enterprise Network Assurance 300-445 Prüfungsfragen mit Lösungen (Q91-Q96):

91. Frage
When selecting a Cisco network assurance platform, which factor should be prioritized for web applications?

Antwort: D

Begründung:
For web applications, user experience should be prioritized when selecting a Cisco network assurance platform to ensure optimal performance and usability.


92. Frage
In network assurance, what is the purpose of a local collection agent?

Antwort: B

Begründung:
The purpose of a local collection agent is to gather data from nearby devices within the same network segment, enabling detailed monitoring and analysis of local traffic patterns.


93. Frage
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?

Antwort: D

Begründung:
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.


94. Frage
Which integration type allows for seamless data exchange between Cisco technologies and external systems?

Antwort: B

Begründung:
API integration enables seamless data exchange between Cisco technologies and external systems, facilitating efficient network management and monitoring.


95. Frage
An engineer must configure a wireless alert in the Cisco Meraki dashboard to send an email to support@cisco.
com when a gateway AP loses its link to the network and comes online as a repeater. What set of actions accomplishes these goals?

Antwort: C
