NEW QUESTION # 36
Refer to the exhibit.
An engineer must use Cisco ThousandEyes testing to monitor their Cisco Catalyst SD-WAN fabric. Which SD-WAN component is being monitored by ThousandEyes?
- A. underlay
- B. overlay
- C. GRE tunnels
- D. IPsec tunnels
Answer: A
Explanation:
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)curriculum, understanding the visibility gap between the SD-WAN overlay and the transport underlay is a core competency. The provided exhibit illustrates a ThousandEyes Enterprise Agent deployed on aBranch Edge Routerperforming tests across two distinct paths:Internet(reaching a destination at 64.100.249.90) andMPLS (reaching a destination at 172.29.0.2).
According to the ENNA architecture guidelines, ThousandEyes is primarily utilized to provide hop-by-hop visibility into theunderlaynetwork. While SD-WAN controllers like vManage provide native monitoring for the overlay-the logical IPsec tunnels (Option B) that form the SD-WAN fabric-they often lack granular visibility into the physical service provider paths (the underlay) that carry those tunnels. The exhibit specifically highlights the agent probing the transport networks (Transport VPN0) directly, bypassing the overlay tunnels to measure the raw performance of the ISP and MPLS circuits.
By monitoring theunderlay(Option A), the engineer can identify if high latency or packet loss is caused by a specific hop within the service provider's infrastructure or at a peering point. This "underlay visibility" is critical for troubleshooting SD-WAN performance issues where the overlay may report a tunnel down, but the root cause lies in a BGP routing change or physical fiber cut in the provider network. ThousandEyes Enterprise Agents, natively integrated into Catalyst 8000 and ISR 4000 platforms, allow for this persistent underlay monitoring without additional hardware.
* Overlay (Option C):While ThousandEyes can monitor overlay performance, the exhibit's focus on the raw IP addresses (Internet and MPLS) in the transport VPN indicates an underlay test.
* IPsec/GRE Tunnels (Options B & D):These represent the transport mechanisms of the overlay.
ThousandEyes probes the pathunderthese tunnels to ensure the transport health is sufficient to support the fabric.

NEW QUESTION # 39
The network team has deployed Webex RoomOS Endpoint Agents and integrated Webex Control Hub with ThousandEyes. The VoIP team wants to know which metrics they can collect from the Webex Control Hub view. Where does the VoIP team find the network data?
- A. Network Path
- B. Devices
- C. Settings
- D. Users
Answer: A
Explanation:
According to theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, the integration between ThousandEyes andWebex Control Hubprovides a streamlined troubleshooting experience for collaboration services. For the VoIP team to access the specific ThousandEyes network telemetry-such as latency, loss, and jitter-they must navigate to theNetwork Path(Option B) section within the Troubleshooting tab of the Control Hub.15 TheNetwork Pathvisualization is a direct result of the ThousandEyes Endpoint Agent data being pulled into the Webex interface.16When a user or RoomOS device experiences poor audio or video quality during a meeting, the Control Hub's troubleshooting view displays a "Network Path" line under the participant's details.
17By clicking on this line, the VoIP team can see a hop-by-hop breakdown of the entire route from the collaboration device to the Webex media node. This view highlights specific hops where performance is
"Poor" (red), "Fair" (yellow), or "Good" (green) based on predefined thresholds for latency (>400ms) or loss (>5%).
While "Devices" (Option A) is where the agents are activated, and "Users" (Option C) allows for selecting a specific participant, the actualtelemetry metricsand the visualization of the network route are strictly located in theNetwork Pathview. This integration eliminates the need for the VoIP team to leave the Webex environment for initial triage, as they can identify if a problem is local to the branch office or deep within a service provider's network directly from the "Network Path" dashboard.
NEW QUESTION # 40
Which type of test are we using for these dashboards (Executive and IT Operations)?
- A. Agent to server
- B. Page Load
- C. HTTP server
- D. FTP
Answer: B
Explanation:
According to theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)data analysis guidelines, identifying the underlying test type is the first step in interpreting a dashboard. By observing the metrics displayed across both the Executive and IT Operations dashboards, we can definitively identify the test type asPage Load(Option B).
A Page Load test is a Web-layer test that uses a browser engine (Chromium) to fully render a page and collect advanced metrics beyond simple availability. Evidence for this test type in the dashboards includes:
* Page Completion Time:Displayed on the Executive dashboard map, this metric is specific to how much of the page successfully rendered.
* DOM Load Time:Found in the IT Operations dashboard, the Document Object Model (DOM) time is a browser-centric metric that measures when the page structure has finished loading.
* Waterfall Charts:While not a specific answer option, these are the foundation of Page Load tests, allowing for the timing of individual web components.
SimpleHTTP Servertests (Option A) only measure availability and response codes, missing the rendering metrics seen here.Agent to server(Option C) is a network-layer test that provides path visualization but no browser-level data.FTP(Option D) is a protocol-specific test not used for web application monitoring.
Therefore, the presence of DOM and Page Completion metrics confirms thePage Loadtest type.

NEW QUESTION # 45
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?
- A. Selecting the time period with the lowest network traffic volume.
- B. Capturing both peak and off-peak traffic patterns for a representative view.
- C. Ensuring the time period aligns with the organization's financial year.
- D. Limiting the time period to minimize the amount of data that needs to be analyzed.
Answer: B
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.

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 # 50
A network administrator wants to establish a baseline for CPU utilization on their core routers. Which data source would be MOST appropriate for this purpose?
- A. Network path visualization from ThousandEyes tests
- B. DNS resolution time from ThousandEyes tests
- C. HTTP Server response times from ThousandEyes tests
- D. SNMP data collected from the routers
Answer: D
Explanation:
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)framework, baselining is the process of establishing a "normal" performance profile for network infrastructure to enable the detection of anomalies. When the metric of interest is the internal health of a physical device, such asCPU utilizationon a core router,SNMP (Simple Network Management Protocol)is the industry-standard data source.
SNMP provides direct visibility into the device's control plane and hardware performance. By polling specific Object Identifiers (OIDs) from the router's Management Information Base (MIB), a monitoring system like Cisco Catalyst Centeror a third-party NMS can collect granular data on CPU cycles, memory allocation, and temperature. This "inside-out" telemetry is essential for baselining because it reflects the actual resource consumption of the router during various traffic loads.
Conversely, ThousandEyes tests (Options A, B, and D) provide "outside-in" synthetic data. WhileDNS resolution time(Option A),HTTP response times(Option B), andPath Visualization(Option D) are excellent for measuring end-to-end service delivery and network transit health, they do not report on the router's internal hardware state. For instance, a router could have 99% CPU utilization (indicating a potential crash), yet a ThousandEyes path test might still show a "green" path if the data plane (ASICs) is still forwarding packets efficiently. Therefore, to establish a reliable baseline for hardware-specific metrics like CPU,SNMP data(Option C) is the only appropriate source among the choices.
NEW QUESTION # 51
What is the primary function of a scripting agent in network assurance?

NEW QUESTION # 52
What Meraki platform supports ThousandEyes?
- A. Meraki MV (Smart Cameras)
- B. Meraki MX (Security Appliances)
- C. Meraki MR Series (Wireless Access Points)
- D. All of the above
- E. Meraki MS Series (Switches)
- F. Meraki MG (Cellular Gateways)
Answer: B
Explanation:
According to theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, the native integration of ThousandEyes within the Meraki portfolio is specifically focused on the Meraki MXsecurity and SD-WAN appliances. This integration allows users to install ThousandEyes Enterprise Agents directly on supported Meraki MX hardware, providing critical visibility into the performance of services that distributed users rely on.4 TheMeraki MX (Option A)supports the ThousandEyes Enterprise Agent as a containerized service that can be activated with a single click within the Meraki Dashboard.5This integration is designed to provide better monitoring and testing capabilities for customers interested in improving the quality of their experience and adding the appropriate SD-WAN policies to optimize network performance. By running the agent natively on the MX, administrators can monitor the performance of external applications and services directly from the SD-WAN sites, bridging the gap between local branch health and global internet performance.6 While Cisco continues to expand its assurance integrations across the portfolio, theMR (Wireless),MS (Switching),MV (Camera), andMG (Cellular)series do not currently support the native, "on-box" execution of the ThousandEyes Enterprise Agent. For these other platforms, visibility is typically achieved through passive monitoring viaMeraki Insight (MI)or by deploying ThousandEyes agents on connected client devices (Endpoint Agents) or nearby infrastructure. Therefore, theMeraki MXis the only verified platform supporting native ThousandEyes agent deployment in this context.
NEW QUESTION # 53
An architect needs to measure end-user experience for internal web applications and SaaS products.20 Which ThousandEyes agent should be deployed for this purpose?
- A. Cloud Agent
- B. Enterprise Agent
- C. Synthetic Agent
- D. Endpoint Agent
Answer: D
Explanation:
In the context ofDesigning 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 pe21rformance.
TheEndpoint 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)andScheduled Synthetic Tests.24RUM 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.25Simultaneously, 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.
Comparing other agents:
* Enterprise Agents (Option B)can simulate a user at a branch office, but they cannot provide insight into the specific health of an individual's laptop or their unique Wi-Fi environment.
* Cloud Agents (Option C)are entirely outside the user's network and cannot measure the performance of internal web applications or the "last mile" connectivity of the employee.
* Synthetic Agent (Option A)remains a distractor term.
By deployingEndpoint Agents, the architect ensures they have granular, contextual data that correlates application performance directly with the user's device and local network environment.
