VMware vRealize Network Insight: Install, Configure, Manage [V6.1] — Lesson 1: vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity

Learning Objectives

• Identify the architecture and operational choices that shape vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity.
• Run normal and boundary tests and record the outcome in vRNI deployment plan and data-source readiness assessment.
• Separate root cause from symptom when investigating a collector placed where it cannot reach management interfaces in a secured zone.

Detailed Topics

• VRealize Network Insight architecture
• Platform and collector nodes
• Sizing
• Deployment
• Licenses
• Certificates
• DNS
• NTP
• Data sources
• Credentials
• And connectivity
• Decision ownership, prerequisites, and acceptance evidence for vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The instructor builds a representative scenario for vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity, narrating each decision and showing how it contributes to a vRealize Network Insight 6.1 service that discovers network topology, analyzes traffic flows, validates application paths, identifies security opportunities, and accelerates troubleshooting. The demonstration records vRNI deployment plan and data-source readiness assessment so learners can compare design intent with observable behavior.

Hands-On Exercise

Work through a role-based scenario involving vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity. Validate the expected path, test “a collector placed where it cannot reach management interfaces in a secured zone,” choose the safest corrective action, and capture the reasoning and outcome in vRNI deployment plan and data-source readiness assessment.

1. Confirm scope, access, sample workloads, and acceptance criteria.
2. Perform the configuration or operation using a controlled sequence.
3. Inspect outputs and downstream effects rather than relying on task status alone.
4. Close with a support note, preventive action, and reproducible validation step.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how vRNI deployment plan and data-source readiness assessment should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

Diagnose vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity by checking effective state, ownership, dependencies, health, logs, and recent changes. Use vRNI deployment plan and data-source readiness assessment to locate the earliest divergence. Treat “a collector placed where it cannot reach management interfaces in a secured zone” as a hypothesis until the same test passes after correction and under a boundary condition.

Validation Checklist

• Configuration and source state used for vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity are versioned or otherwise traceable.
• Vrni deployment plan and data-source readiness assessment shows both baseline and accepted result.
• Security, performance, dependency, and resilience side effects are considered where relevant.
• Recovery steps and handover notes are usable by an operations practitioner.

Lesson Outcome

Learners can apply vRealize Network Insight architecture, platform and collector nodes, sizing, deployment, licenses, certificates, DNS, NTP, data sources, credentials, and connectivity, explain the decisions made, and defend the result with vRNI deployment plan and data-source readiness assessment.
