Cisco CCNP Designing and Implementing Enterprise Network Assurance with ThousandEyes (300-445 ENNA)

When users report that an app is slow, can your team prove where the problem is? Many teams cannot tell whether a fault is on the endpoint, inside the corporate network, or out on the internet. This course trains network engineers to use Cisco ThousandEyes to find that answer before users open tickets. It also prepares them for the 300-445 ENNA exam toward CCNP Enterprise.

Role fit: This is professional-level training for network engineers working on enterprise network assurance. Team Leads supporting Catalyst 9K environments will find it practical. It covers hosting Enterprise Agents on IOS-XE, including app-interface trunk and VLAN settings and the agent lifecycle commands.

Time investment: Plan for about 22 hours per learner across 27 skills. Learners get the most value with access to a ThousandEyes environment, because hands-on configuration supports both real-world use and exam preparation.

Change-management notes:

• Production rollouts of Endpoint Agents usually use bulk deployment.
• Enterprise Agents on Catalyst 9K switches need supported SSD storage.
• Alert rules need tuning so they fire when needed without flooding the team. The course practices this directly.

Two 20-question review quizzes help learners identify weak areas before the exam. Two lab challenges then validate hands-on setup of agents, alerts, tests, and dashboards.

IT teams complete this training to move from reactive firefighting to proactive network assurance with Cisco ThousandEyes. The course is built on hands-on configuration of agents, tests, alerts, and dashboards, so engineers can put what they learn to work in a live environment.

Scenarios your team will be ready for:

• Prove value on day one. When leadership invests in ThousandEyes and wants immediate results, your engineers will know which agent types deliver testing right away and which ones need deployment work first.
• Isolate where the problem lives. Engineers learn to compare cloud agent and enterprise agent results to tell whether degraded performance comes from your network and endpoints, the internet path, or the target. They also learn to use BGP and routing tests when only parts of the internet are misbehaving.
• Catch issues before users report them. The course explains why real user tests are authentic but sporadic, and why scheduled synthetic tests fill the gaps. Your team can detect a problem before users even reach the affected site.
• Deploy and maintain agents on IOS-XE infrastructure. Engineers practice hosting enterprise agents on IOS-XE platforms that support app hosting, including manual install steps, app interfaces, and the operational checks needed to bring agents online. They also troubleshoot Layer 2 and Layer 3 connectivity issues, such as trunk VLAN allowed lists, that can keep agents offline.

Business impact: faster mean-time-to-innocence for the network team, alert rules tuned to trigger when needed without flooding on-call staff, and safer test configurations that avoid overloading target servers. The course closes with lab challenges that mirror a real deployment, so your team is ready to configure ThousandEyes, not just prepare for the 300-445 ENNA exam.

Knowledge

• How ThousandEyes components fit together: agents, tests, alerts, views, and dashboards
• The differences between endpoint, enterprise, and cloud agents, where each is deployed, and which one supports day-one testing
• Synthetic active testing versus passive real user monitoring, including monitored domains and recorded sessions
• Test types across web, network, routing (BGP), DNS, and voice
• Alert logic, including threshold operators, global conditions, agent-percentage triggers, and event types

Ability

• Install endpoint agents manually and plan bulk deployment options for production rollouts
• Host enterprise agents on Cisco Catalyst 9K switches with SSDs using IOS-XE app hosting, from SSD install and app interface trunk and VLAN setup through the deploy, activate, start, stop, and deactivate lifecycle
• Troubleshoot agent Layer 2 and Layer 3 connectivity and safely change agent settings such as IP addresses
• Build alert rules that trigger when needed without flooding the team with noise
• Configure and interpret web, network, routing, DNS, and voice tests, including test intervals, agents, and viewpoints, so the team can isolate whether an issue sits in the local network, the internet, or the target
• Deploy dashboards and widgets, and manage users, account groups, and platform administration
