NEW QUESTION # 12
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 the Designing 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 # 13

Answer: C
Explanation:
Prioritizing performance monitoring enhances user satisfaction when selecting a Cisco network assurance platform.
NEW QUESTION # 14
Review the exhibits. Based on the evidence, what seems to be the underlying issue?
Answer: B
NEW QUESTION # 15
What are the different ways to deploy a ThousandEyes Agent in a Switch? (Choose all that apply)
Answer: C
Explanation:
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)architecture, the deployment of ThousandEyes Enterprise Agents on switching infrastructure is designed to be highly flexible, catering to different management styles and network scales. Modern Cisco switches, specifically theCatalyst
9300 and 9400 Series, support the execution of containerized applications directly on the switch's hardware through theCisco IOS XE Application Hostingframework.1 Application Hosting (Option A)refers to the manual method using the Cisco IOS XE Command Line Interface (CLI). An engineer can use app-hosting commands to install, configure, and manage the Docker- based Enterprise Agent.2This provides granular control over resource allocation and networking for the container.Catalyst Center (Option B)provides a GUI-driven, automated workflow to deploy agents at scale across an entire campus fabric.3It simplifies the lifecycle management by handling the installation and activation across multiple switches simultaneously. For switches acting as edge devices in an SD-WAN fabric, Catalyst SD-WAN Manager (Option C)orchestrates the deployment through centralized policies and templates, allowing the agent to be pushed as part of a device configuration. Finally, while theThousandEyes Portal (Option D)is the management plane for tests, it is also where the Docker image and Account Group Token are obtained for any of the aforementioned deployment methods.
Each method provides the same end result: an Enterprise Agent running "on-box" to provide deep visibility into the network path starting directly from the access or core layer. Therefore,All of the above(Option E) is the correct answer as it encompasses the manual, automated, and orchestrated methods available for switch- based deployment as per the 300-445 ENNA official guidelines.
NEW QUESTION # 16
You are investigating intermittent failures in a ThousandEyes transaction test targeting a web application that uses Basic Authentication. The failures occur randomly across different agents and times of day. What steps would you take to troubleshoot and resolve the issue? (Select all that apply)
Answer: B,C,D
Explanation:
Troubleshooting intermittent performance issues is a core component of the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum. When a transaction test using Basic Authentication fails randomly, the engineer must employ a multi-layered diagnostic approach to determine if the fault lies with the credentials, the network path, or the application server.
The first step is to verify the correctness of credentials (Option B). Because Basic Authentication encodes credentials in the header, any change in user permissions or account lockouts will trigger immediate failures. Performing manual logins from various geographical locations helps rule out location-based access control lists (ACLs) or regional IdP sync issues.
The most data-rich diagnostic step is to analyze the ThousandEyes waterfall charts and HTTP response codes (Option C). The waterfall view allows the engineer to see if the failure happens during the initial 401 Unauthorized challenge or after the credentials are sent. If the charts show high "Wait Time" or 5xx errors, the issue is likely server-side latency or instability. If the "Connect Time" is high, the problem may be network-layer congestion.
Finally, if the telemetry indicates that the network path is healthy but the server is intermittently returning errors or timing out, the engineer should contact the web application vendor (Option D).
Providing the vendor with the specific ThousandEyes "Share Link" allows them to see the exact same packet-level and browser-level data, proving that the issue is not with the client's network but with the server-side infrastructure. Disabling authentication (Option A) is not a valid troubleshooting step for a test designed specifically to monitor an authenticated workflow.
