CompTIA Server+ — Practice Questions and Mock Exam

CompTIA Server+ (SK0-005) validates the skills required to manage and troubleshoot servers in data centers, on-premises, and hybrid environments. It covers server hardware installation, server administration, security and disaster recovery, and troubleshooting. Server+ is the industry standard for server professionals and aligns with NICE and DCWF cybersecurity workforce frameworks. Recommended prerequisites include CompTIA A+ certification or equivalent knowledge with two years of hands-on experience in a server environment.

Server Administration carries the most weight at 30%, covering OS installation against core network services, staying up via clustering and redundant paths, and virtualization. Troubleshooting follows at 28%, then Security and Disaster Recovery at 24% and Server Hardware Installation and Management at 18% — the smallest domain, though it still covers RAID configuration and out-of-band management that show up again inside the Troubleshooting questions.

Administration and Troubleshooting together make up well over half the exam, so the blueprint favors candidates who can both configure a server correctly the first time and diagnose it when something breaks later. Hardware Installation's smaller share doesn't reduce its importance elsewhere: RAID levels and physical component knowledge from that domain resurface as the technical foundation for Troubleshooting and Security questions rather than staying contained to their own section.

The SK0-005 exam contains a maximum of 90 questions in a 90-minute window, mixing multiple-choice and performance-based formats. Performance-based questions run through simulated environments (configuring RAID arrays, troubleshooting network connectivity, interpreting server logs) rather than asking for a fact recalled from memory. The passing score is 750 on a scale of 100 to 900.

Every domain of the COMPTIA-SERVER exam has enough questions in the pool to practice it in depth. A mock exam asks 90 questions in one sitting, on the same 90-minute clock as the real thing.

How long you'll need depends on how much hands-on experience you bring. The rest is set by the vendor: how the exam is delivered, how soon you can retake it, and how long the credential stays valid.

CompTIA Server+ SK0-005 is delivered at Pearson VUE testing centers worldwide or online with a proctor, in English and Japanese. Server+ moved into CompTIA's continuing education program on October 1, 2025 and now runs on a three-year renewal cycle with 50 CEUs plus annual CE fees. Earning or renewing Server+ does not renew any other CompTIA certification, and a 30-day grace period applies for outstanding CEUs or fees.

Performance-based questions get underestimated relative to their difficulty — practicing RAID configuration, command-line administration, and network troubleshooting hands-on matters more than reading about them. Troubleshooting is the second-largest domain at 28%, and it rewards systematic methodology over memorized fixes, the same way the standard RAID levels get confused when candidates know the names but not which configuration survives which kind of drive failure. Physical hardware topics (hot-swappable components, out-of-band management through IPMI, iLO, or iDRAC, power redundancy) are easy to skip in a mostly software-focused study plan, and so is the fact that SK0-005 tests Windows Server and Linux administration equally rather than favoring one platform.
