Server+ SK0-005 Exam Objectives: All Four Domains Broken Down

The efficient way to prepare is to follow the weighting rather than your comfort zone. CompTIA Server+ SK0-005 tells you exactly where the points are, and this article walks through all four domains, what each covers in practice, and how to prioritize your time.

For exam mechanics, see the format guide. For the whole path, the complete Server+ guide ties it together.

The weighting at a glance

Server Administration and Troubleshooting together are 58% of the exam. Plan your study hours accordingly — those two domains decide most of your result.

Domain 1: Server Hardware Installation and Management (18%)

The physical foundation — the smallest domain by weight, but concrete and testable.

Expect installing physical hardware (racking, chassis types and unit sizes, cable management, power connector types), server components and their purposes, and configuring server storage including RAID levels and storage technologies. You'll also cover the power and cooling considerations of a server room or data center. If you've built or racked servers, this domain will feel familiar; if not, hands-on time with real or lab hardware pays off.

Domain 2: Server Administration (30%)

The largest domain, and the operational heart of the exam.

It covers server operating system administration and installation, storage and virtualization management, network configuration and services on servers, and basic scripting for automation. High availability concepts live here too. This is where day-to-day server work is tested — deploying and configuring OSes, managing virtualization, and keeping services running. Because it's the biggest domain and heavily practical, it deserves the most study and lab time.

Domain 3: Security and Disaster Recovery (24%)

Protecting servers and keeping the business running when things go wrong.

You'll cover physical and logical security controls, server hardening, access controls, and data security, plus the disaster recovery half: backup methods and rotation schemes, replication, and recovery planning (including concepts like RTO and RPO). Server security is practical and control-driven, so understand not just what each control is but when and why you'd apply it. Disaster recovery rewards knowing the trade-offs between backup and recovery strategies.

Domain 4: Troubleshooting (28%)

The second-largest domain, and the reason hands-on experience matters so much.

It covers diagnosing and resolving problems across hardware, software, storage, security, and networking on servers. This domain draws on all three others, so it's best studied throughout rather than saved for last. It rewards a methodical approach — identify the problem, establish a theory, test it, implement a fix, and verify — applied to realistic server scenarios. People who've actually fixed servers have a real advantage here.

How to sequence your study

A sensible order: start with Server Hardware to build the physical foundation, invest heavily in Server Administration as the largest and most practical domain, cover Security and Disaster Recovery, and weave Troubleshooting throughout since it builds on everything. The study plan lays this out week by week.

Because so much of Server+ is applied, hands-on labs mapped to the objectives are the most efficient way to build real skill.

Practice against the objectives: CompTIA Server+ CertMaster Labs (SK0-005) offers guided, objective-aligned hands-on exercises. To cover every objective in a structured course, pair it with CertMaster Learn (SK0-005). As an Authorized CompTIA Partner, these are the official versions.

FAQ

Which domain is most important? Server Administration at 30%, closely followed by Troubleshooting at 28%. Together they're nearly 60% of the exam.

How technical is the Hardware domain? It's concrete and physical — racking, cabling, storage, and RAID. Hands-on familiarity with server hardware helps, even in a lab.

Do I need to know scripting? Basic scripting for automation is part of Server Administration. You don't need to be a developer, but recognize and understand simple scripts.

What disaster recovery concepts are tested? Backup methods and rotation, replication, and recovery planning concepts like RTO and RPO, plus the trade-offs between strategies.

Is troubleshooting just common sense? No. It's a methodical, scenario-driven skill that draws on every domain, and it's best built through hands-on practice.
