CompTIA Server+ (SK0-005) Study Guide [180 Minute Read]

A First-Principles Approach to Server Administration

Welcome to the CompTIA Server+ (SK0-005) Study Guide. This guide moves beyond surface-level memorization. It is designed to build a robust mental model of how servers are installed, managed, secured, and troubleshot—understanding the why behind every administrative decision, not just the what.

Each topic is aligned with the official CompTIA Server+ SK0-005 Exam Objectives, targeting the specific cognitive skills required for success. The SK0-005 exam heavily emphasizes "given a scenario" questions—roughly 55% of questions require you to apply knowledge to realistic situations, not just recall definitions. This guide prepares you to reason through those scenarios, not just recognize answers.

Exam Details: Up to 90 questions (multiple choice and performance-based) | 90 minutes | Passing score: 750/900

Prerequisites: CompTIA A+ certification or equivalent knowledge; 18–24 months hands-on server experience recommended. This guide assumes you understand basic networking, PC hardware, and OS fundamentals.

Exam Domain Weights

Server Administration dominates at 30%—if you're pressed for time, start there. But don't neglect Troubleshooting at 28%; the scenario-based questions in that domain require deep cross-domain knowledge. Together these two domains account for over half the exam.
