Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q49-Q54):

NEW QUESTION # 49
What is an important consideration when choosing a time period for collecting data to establish a baseline for interface utilization on a critical network link?

Answer: C

Explanation:
Establishing an accurate baseline is a cornerstone of theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)methodology. A baseline must represent the "typical" behavior of the network across its standard operating cycle to be useful for anomaly detection and capacity planning. When monitoring interface utilization on a critical link, it is vital tocapture both peak and off-peak traffic patterns (Option C).
Most enterprise networks exhibit cyclical traffic patterns, often referred to as "diurnal" cycles, where utilization spikes during business hours (peak) and drops significantly at night or on weekends (off-peak). If an engineer only collects data during the lowest volume period (Option A), the baseline will be unrealistically low, leading to "false positive" alerts when normal business traffic returns. Conversely, only capturing peak data might hide background synchronization tasks or backup windows that occur during off-hours.
By selecting a representative time period-typically one full week or a month-the engineer ensures the baseline accounts for variations such as Monday morning "logon storms," mid-week steady states, and weekend maintenance. This comprehensive view allows the assurance platform (such asCisco Catalyst CenterorThousandEyes) to calculate a standard deviation and establish dynamic thresholds. If utilization deviates from these historically representative norms, the system can trigger an alert based on a true anomaly rather than a predictable daily surge. Aligning with a financial year (Option B) is irrelevant to technical performance, and limiting the data (Option D) compromises the baseline's statistical validity.


NEW QUESTION # 50
Which tool is commonly used for configuring network tests related to TCP/UDP performance?

Answer: C

Explanation:
Thousand Eyes is commonly used for configuring network tests related to TCP/UDP performance, offering comprehensive monitoring and analysis capabilities.


NEW QUESTION # 51
Drag and drop the Cisco Network Assurance platforms from the left onto the corresponding business cases on the right.

Answer:

Explanation:

Explanation:
AppDynamics
Catalyst Center
ThousandEyes
Meraki
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)architecture, each platform is positioned to address a distinct domain of visibility and management within the modern IT visibility framework.
AppDynamics(matched to Case 1) is specifically engineered for Full-Stack Observability and Application Performance Monitoring (APM). Its unique focus is linking technical application performance-such as code- level execution and database queries-directly to business outcomes and real-time business metrics. By doing so, it allows organizations to pinpoint how application latency impacts revenue or user satisfaction, making it the primary choice for business impact analysis.
Catalyst Center, formerly DNA Center (matched to Case 2), serves as the foundational controller for campus and enterprise network infrastructure. It leverages AI-driven insights to automate network operations, enforce security policies, and provide at-a-glance health monitoring for local devices and clients. It is the definitive management system for connecting and securing "inside" the corporate network perimeter.
ThousandEyes(matched to Case 3) provides "Internet Intelligence" and is the key solution for monitoring the service delivery chain across environments the enterprise does not own. By utilizing a global network of Cloud, Enterprise, and Endpoint agents, it provides end-to-end visibility from any user location to any application (SaaS or Cloud) over any network (Internet, ISP, or WAN).
Meraki(matched to Case 4) is a cloud-first platform designed for managing highly distributed network environments and IoT deployments. It provides end-to-end visibility through a simplified dashboard that integrates wireless health, switching, and security across thousands of sites, making it ideal for lean IT teams managing distributed retail or branch locations.
Each platform utilizes different data collection methods-active synthetic testing for ThousandEyes and passive monitoring/AI telemetry for Catalyst Center-to ensure comprehensive network assurance across the entire enterprise ecosystem.


NEW QUESTION # 52
Which monitoring method involves actively probing network devices and applications to collect data?

Answer: A

Explanation:
Synthetic monitoring involves actively probing network devices and applications to collect data, as opposed to passive monitoring which observes network traffic passively.


NEW QUESTION # 53
Which authentication method is commonly used in synthetic web tests for secure access to web applications?

Answer: A

Explanation:
Basic authentication is commonly used in synthetic web tests for secure access to web applications, providing a simple yet effective authentication mechanism in network assurance.
