CompTIA CV0-004 Glossary: Cloud, Virtualization, and Operations Terms

CompTIA CV0-004 glossary of cloud deployment, service models, virtualization, and operations terms.

On this page

Use this glossary when CompTIA Cloud+ (CV0-004) terms start to blur together. The goal is practical recognition, not encyclopedia coverage.

Core terms

Term Exam meaning
IaaS Infrastructure as a service: virtualized compute, storage, and networking managed by the customer above infrastructure.
PaaS Platform as a service: managed runtime or service platform for applications.
IaC Infrastructure as code: repeatable infrastructure definitions.
RTO Recovery time objective: acceptable time to restore service.
RPO Recovery point objective: acceptable data loss window.
Shared responsibility Security and operations split between provider and customer.

Confusion pairs

Pair How to separate them
Cloud architecture vs Deployment and automation Ask which layer the scenario is testing, then match the answer to that layer only.
Control vs evidence A control changes behavior; evidence proves behavior or supports investigation.
Managed service vs custom build Managed services win for lower operational effort unless the requirement needs unsupported customization.
Prevention vs detection Prevention blocks or reduces a bad event; detection finds or reports that it happened.

How to study terms

Do not memorize terms in isolation. For each term, write one scenario where it is the best answer, one scenario where it is a distractor, and one signal that proves it worked.
