An independent study guide for VMware Certified Professional – VMware vSphere Foundation Administrator · by Tony Rough
Know which vSphere, vSAN and VCF Operations setting fits, and why.
Due on Amazon in October 2026, in Kindle and paperback editions.
This independent study guide for the VMware Certified Professional – VMware vSphere Foundation Administrator (VCP-VVF Administrator) exam turns what 2V0-16.25 expects you to understand into the comparisons, decisions and traps that day-to-day VVF administration depends on. The exam is based on VMware vSphere Foundation 9.0, and the book is too, written from Broadcom's own 9.0 documentation.
Thirteen chapters, each one readable on its own, that together cover every exam objective:
There are no exam questions in this book. It explains the knowledge the exam looks for, so you can reason through questions you have never seen and bring the same judgement to a real vSphere Foundation environment.
Written by Tony Rough, a cloud architect with over twenty years in IT infrastructure, whose VMware certifications began with vSphere data centre virtualisation and went on to the VCAP-DCD and VCAP-DCA in data centre design and administration.

Short excerpts from the book, exactly as they appear in it, so you can see how it explains things.
The opening of chapter 1 · Chapter 1: Virtualization and the VVF 9.0 architecture
VMware vSphere Foundation (VVF) 9.0 is a workload platform built on the vSphere hypervisor, with storage virtualization, Kubernetes and operations management added on top. Before any deployment or configuration task makes sense, an administrator needs a firm grip on what virtualization actually does, why organisations adopt it, and which pieces make up a VVF environment. This chapter covers those foundations, separates VVF from its larger sibling VMware Cloud Foundation (VCF), and lists the names that changed in the 9.0 release so that older terminology does not cause confusion later.
A comparison table · Chapter 1: Virtualization and the VVF 9.0 architecture · Principles of virtualization
Each virtual machine is stored as a group of files on a datastore. Because the whole machine is files, it can be copied, moved, archived and backed up much like any other data, which is the basis for templates, cloning and snapshots.
| File | Purpose |
|---|---|
.vmx |
Virtual machine configuration file |
.vmdk |
Virtual disk descriptor (characteristics of the disk) |
-flat.vmdk |
Virtual disk data |
.nvram |
BIOS or EFI settings |
.vswp |
Virtual machine swap file |
.vmsd / .vmsn |
Snapshot metadata / snapshot memory state |
.vmss |
Suspend state |
vmware.log |
Current log file (older logs are numbered) |
.vmtx |
Replaces the .vmx when a virtual machine is converted to a template |
A common trap · Chapter 1: Virtualization and the VVF 9.0 architecture · Principles of virtualization
Common trap: Assuming that hypervisor isolation makes network segmentation between virtual machines unnecessary - isolation stops one virtual machine touching another’s memory and data directly, but traffic between virtual machines on a shared network can still carry an attack, so virtual networks still need protecting.



Some sections of the book, free to read online:
What VVF 9.0 includes, what only VCF 9.0 adds, and where the two share a code base.
Storage pools or disk groups: the hardware, memory and network each vSAN architecture needs, and how failures differ.
The rules in a vSAN storage policy, their defaults, and how mirroring compares with erasure coding.
Per-host or vCenter-managed networking, and the features only a distributed switch brings.
Cluster resource percentage, slot policy and dedicated failover hosts compared, with what each reserves.
How each library type gets and shares its content, and when subscribers download items.
The two vSAN encryption services, the threat each addresses and which one needs a key provider.
Node layouts, failure protection and latency limits for each VCF Operations cluster model, and how a VVF platform reaches them.
