Cisco 300-445 Exam Syllabus Topics:

TopicDetails
Topic 1
  • Platforms and Architecture: This domain covers understanding monitoring agent types and placement, active versus passive monitoring, and ThousandEyes WAN Insights. It addresses Cisco platform integrations, metric baselines, and selecting appropriate integration methods and assurance platforms based on business requirements.
Topic 2
  • Data Collection Implementation: This domain focuses on deploying enterprise and endpoint agents across infrastructure and end-user devices. It covers configuring network, DNS, voice, web, and endpoint tests using ThousandEyes and Meraki Insights, along with implementing synthetic web tests and authentication methods.
Topic 3
  • Insights and Alerts: This domain addresses configuring alert rules based on network conditions and end-user experience factors. It covers selecting metrics for stakeholders, validating alerts, and recommending network optimization for capacity planning.
Topic 4
  • Data Analysis: This domain encompasses diagnosing network issues like packet loss, congestion, routing, and jitter, plus end-device problems. It includes analyzing web application performance and identifying security threats such as DDoS attacks, DNS hijacking, and BGP hijacking.

Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q96-Q101):

NEW QUESTION # 96
Which Thousand Eyes test is specifically designed to assess the performance of DNS resolution?

Answer: D

Explanation:
The DNS test in Thousand Eyes is specifically designed to assess the performance of DNS resolution, identifying latency and response time issues in network assurance.


NEW QUESTION # 97
Refer to Exhibit:

A network engineer is deploying a Cisco ThousandEyes agent to monitor the network for a SaaS application without affecting the performance of the employee endpoints. Which ThousandEyes agent must be deployed to obtain the network metrics from branch A?

Answer: A

Explanation:
In the framework ofDesigning and Implementing Enterprise Network Assurance (300-445 ENNA), selecting the appropriate ThousandEyes agent type is critical to balancing visibility requirements with infrastructure constraints. For Branch A, the primary objective is to gain network-layer metrics (such as latency, packet loss, and jitter) and path visualization for a SaaS application while strictly avoiding any performance impact on employee endpoints.
TheEnterprise Agent(Option C) is the correct choice because it is designed for "inside-out" monitoring from within the corporate network environment. These agents are lightweight software probes that can be deployed on existing network infrastructure, such asCisco Catalyst 9300/9400 switchesorCatalyst 8000 Edge Platforms, using Docker containers or virtual machines. By hosting the agent on the branch router or a dedicated local server, the engineer can execute synthetic tests to the SaaS provider's destination. This approach provides the necessary network vantage point from Branch A without requiring any software installation or resource consumption on the individual employee workstations (endpoints).
Other agent types do not satisfy the specific constraints of this scenario:
* Endpoint Agentsare installed directly on user devices (Windows/macOS) to provide "last-mile" visibility. However, they use the endpoint's CPU and memory, which contradicts the requirement to not affect endpoint performance.
* Cloud Agentsare maintained by Cisco in global ISP data centers. While they provide "outside-in" visibility, they cannot capture internal branch network characteristics or the specific path from Branch A's internal local area network.
* Application Agentis a non-standard term and does not exist as a standalone agent type within the ThousandEyes architecture.
Therefore, deploying anEnterprise Agentwithin the branch infrastructure ensures that the network engineer obtains high-fidelity network metrics while keeping employee devices entirely unburdened.
Introduction to ThousandEyes
This video provides an essential overview of how ThousandEyes agents function within a CCNP-level enterprise network assurance strategy.


NEW QUESTION # 98
You want to monitor Microsoft Teams using ThousandEyes endpoint agents. Which tests are available for this type of application monitoring?

Answer: C

Explanation:
According to theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)best practices for collaboration monitoring,Microsoft Teams(as well as Webex and Zoom) is monitored using a combination ofScheduled and Dynamic tests(Option D).
* Scheduled Tests:These are used to proactively monitor the reachability and performance of the Microsoft Teams infrastructure. The Teams template typically includes scheduled HTTP Server tests to teams.microsoft.com and login.microsoftonline.com, along with network-layer tests to theTeams Transport Relay(e.g., worldaz.tr.teams.microsoft.com). These provide a continuous baseline of connectivity regardless of whether a user is currently in a call.
* Dynamic Tests:These are a unique feature for collaboration monitoring. When an Endpoint Agent detects that the Teams application has initiated a real-time media session (audio or video call), it automatically triggers aDynamic Testto the specific IP and port being used for that call. This allows IT teams to see the exact network path-including hop-by-hop latency and loss-of the actual call traffic while the session is active.
Real User Tests (Option C)are generally not used for Teams monitoring in the same way they are for web- based SaaS apps. Because most users utilize the Teamsdesktop clientrather than the browser, the RUM browser extension cannot capture the rich telemetry of the desktop application's internal signaling and media streams. Therefore, the specialized "Automated Session Testing" provided byDynamic Tests, combined with the proactive health checks ofScheduled Tests, constitutes the complete assurance strategy for Microsoft Teams.


NEW QUESTION # 99
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?

Answer: D

Explanation:
In the Designing 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 as CPU utilization on 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 Center or 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.


NEW QUESTION # 100
How does the integration between Cisco technologies streamline network management tasks?

Answer: A

Explanation:
Integration of Cisco technologies automates configuration workflows, simplifying network management tasks and improving efficiency.
