What's inside

2V0-16.25 isn't about remembering where a menu lives. It's about knowing which vSphere Foundation setting, policy, switch or VCF Operations feature meets a requirement, and why the alternatives fall short.

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.

Organised by technology

Thirteen chapters, each one readable on its own, that together cover every exam objective:

Inside

Understanding, not memorising

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.

Look inside

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.
