VMware vSphere Foundation – Build, Manage, Operate[V9.0] FT — Lesson 2: Hosts, vCenter, Clusters, Networking, NFS, iSCSI, and VM Lifecycle

Learning Objectives

• Optimize the roles, prerequisites, dependencies, and decision points that shape hosts, vcenter, clusters, networking, nfs, iscsi, and vm lifecycle.
• Verify the workflow and produce Foundation build workbook and storage-network acceptance test that another practitioner can review and repeat.
• Diagnose “iSCSI paths appearing present while all traffic uses a single unintended VMkernel route” without introducing an unverified production change.

Detailed Topics

• host and vCenter build
• cluster configuration
• standard and distributed networking
• VMkernel services
• NFS datastores
• iSCSI configuration
• multipathing
• virtual-machine creation
• content and templates
• infrastructure validation
• Decision ownership and acceptance evidence for hosts, vcenter, clusters, networking, nfs, iscsi, and vm lifecycle
• Relevant security, performance, resilience, rollback, and support considerations

Instructor Demonstration

The instructor demonstrates host and vCenter build, cluster configuration, standard and distributed networking, VMkernel services, NFS datastores, iSCSI configuration, multipathing, virtual-machine creation, content and templates, infrastructure validation in a representative environment. Each material checkpoint is captured in Foundation build workbook and storage-network acceptance test, and the walkthrough contrasts the intended state with a condition where iSCSI paths appearing present while all traffic uses a single unintended VMkernel route.

Hands-On Exercise

Complete a controlled implementation or analysis for Hosts, vCenter, Clusters, Networking, NFS, iSCSI, and VM Lifecycle. Establish a known baseline, introduce or reproduce “iSCSI paths appearing present while all traffic uses a single unintended VMkernel route,” isolate the proven cause, apply a reversible correction, and record the accepted result in Foundation build workbook and storage-network acceptance test.

1. Confirm scope, identities, infrastructure, dependencies, and expected result.
2. Execute the planned configuration or operational sequence while preserving checkpoints.
3. Test one expected path, one boundary condition, and the identified failure path.
4. Retest after correction and document rollback, ownership, and preventive action.

Scenario Analysis

• Decide which requirement or dependency has the greatest influence on hosts, vcenter, clusters, networking, nfs, iscsi, and vm lifecycle.
• Compare two valid implementation or recovery choices and identify the evidence that would distinguish them.
• Explain how Foundation build workbook and storage-network acceptance test should be reviewed, retained, and handed to the next owner.

Troubleshooting Guidance

Begin with effective configuration, recent changes, connectivity, health, logs, and timing. Use Foundation build workbook and storage-network acceptance test to find the earliest divergence between expected and observed behavior. Treat “iSCSI paths appearing present while all traffic uses a single unintended VMkernel route” as a hypothesis until the corrected path passes both the original test and a boundary condition.

Validation Checklist

• The implemented state for hosts, vcenter, clusters, networking, nfs, iscsi, and vm lifecycle is traceable to approved inputs.
• Foundation build workbook and storage-network acceptance test contains baseline, test, correction, and accepted-result evidence.
• Security, capacity, performance, resilience, downstream impact, and rollback were considered where relevant.
• Monitoring, escalation, recovery, and support ownership are clear enough for operational use.

Lesson Outcome

Learners can apply Hosts, vCenter, Clusters, Networking, NFS, iSCSI, and VM Lifecycle, explain the decisions made, and defend the result with Foundation build workbook and storage-network acceptance test.
