VMware Virtualization Basics — Lesson 3: Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics

Learning Objectives

• Translate a realistic infrastructure or application requirement into an executable approach for Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics.
• Use VM network-and-storage map with connectivity checks to verify configuration, connectivity, security, and expected behavior.
• Explain how to recover safely when a VM connected to a valid port group on the wrong VLAN occurs.

Detailed Topics

• Standard switches
• Port groups
• VLAN concepts
• Physical adapters
• Vmkernel services
• Datastores
• VMFS
• NFS
• Storage paths
• And connectivity basics
• Decision ownership, prerequisites, and acceptance evidence for Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The instructor builds a representative scenario for Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics, narrating each decision and showing how it contributes to a usable understanding of VMware virtualization fundamentals, including ESXi hosts, vCenter inventory, virtual machines, networking, storage, resource use, availability, and routine administration. The demonstration records VM network-and-storage map with connectivity checks so learners can compare design intent with observable behavior.

Hands-On Exercise

Configure and test Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics with representative infrastructure or application data. Use “a VM connected to a valid port group on the wrong VLAN” as the troubleshooting challenge, compare hypotheses, retest the affected path, and complete VM network-and-storage map with connectivity checks for review.

1. Define the requirement and identify dependencies before changing the environment.
2. Create a baseline result that can be compared with later changes.
3. Reproduce the exception and test one hypothesis at a time.
4. Complete the evidence record and obtain peer or instructor review.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how VM network-and-storage map with connectivity checks should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

Avoid changing multiple settings at once while troubleshooting Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics. Preserve the failing example, review VM network-and-storage map with connectivity checks, and verify whether “a VM connected to a valid port group on the wrong VLAN” is the root cause. After remediation, confirm downstream effects and add a monitoring action.

Validation Checklist

• The scope of Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics is clear, including what is deliberately excluded from the test.
• Evidence in VM network-and-storage map with connectivity checks supports each material decision and outcome.
• A negative test demonstrates that controls reject or expose an invalid condition.
• Open risks, owners, due actions, and production safeguards are documented.

Lesson Outcome

Learners can apply Standard switches, port groups, VLAN concepts, physical adapters, vmkernel services, datastores, VMFS, NFS, storage paths, and connectivity basics, explain the decisions made, and defend the result with VM network-and-storage map with connectivity checks.
