CompTIA Server+ (SK0-005) Practice Exams 2026

About the CompTIA Server+ SK0-005 Exam

CompTIA Server+ is a vendor-neutral certification that validates the hands-on skills required to manage and troubleshoot server hardware and software technologies in data center environments. The SK0-005 version covers modern server infrastructure including physical and virtual servers, storage technologies, disaster recovery planning, and security hardening. Server+ is recognized by the U.S. Department of Defense (DoD 8570) for server-focused technical roles and is one of the few CompTIA certifications that carries lifetime validity, meaning it never expires and requires no renewal.

The SK0-005 exam consists of a maximum of 90 questions (multiple-choice and performance-based) to be completed in 90 minutes, with a passing score of 750 on a 100-900 scale. Performance-based questions (PBQs) simulate real-world server administration scenarios such as configuring RAID arrays, troubleshooting hardware failures, managing storage, and implementing backup solutions. The exam costs $358 USD and is delivered at Pearson VUE testing centers worldwide or via online proctored exam. CompTIA recommends having A+ certification and 18-24 months of server administration experience before attempting Server+.

The lifetime certification status makes it particularly attractive for professionals who want a permanent credential validating their server infrastructure expertise.

Why Take CompTIA Server+?

• Lifetime Certification - Server+ Never Expires: Unlike most CompTIA certifications that require renewal every 3 years through Continuing Education Units (CEUs), Server+ is a lifetime certification. Once you pass the SK0-005 exam, your certification remains valid permanently with no renewal fees, no CEU requirements, and no expiration date. This makes Server+ one of the most cost-effective certifications in the CompTIA portfolio, as you invest once and retain the credential for your entire career.
• Validates Hands-On Server Administration Skills: Server+ tests practical server administration competencies across physical and virtual environments, including hardware installation, RAID configuration, OS deployment, virtualization management, backup implementation, and performance monitoring. The performance-based questions (PBQs) simulate real data center scenarios, ensuring that Server+ holders can demonstrate practical skills employers need, not just theoretical knowledge.
• DoD 8570 Recognized for Server-Focused Technical Roles: Server+ is approved under the DoD Directive 8570 framework, making it a recognized credential for server-focused positions within U.S. government agencies, military organizations, and defense contractors. For IT professionals seeking careers in federal data centers, government IT operations, or defense infrastructure, Server+ satisfies baseline certification requirements for server administration roles.
• Career Growth in Server Administration and Data Center Roles: Server+ holders earn $65,000-$90,000 USD annually in server administration and data center operations roles. The certification validates skills directly applicable to positions such as server administrator, data center technician, systems engineer, and infrastructure specialist. As organizations maintain hybrid infrastructure (on-premises servers alongside cloud resources), professionals with validated server hardware and administration skills remain in high demand.

How to Prepare for the Server+ SK0-005 Exam

Server+ preparation typically takes 2-3 months for candidates with hands-on server experience, or 3-5 months for those transitioning from desktop support or help desk roles. The SK0-005 exam emphasizes practical skills through performance-based questions, so hands-on experience with actual server hardware and virtual environments is essential. Most successful candidates combine structured study materials with lab practice using physical or virtual server environments.

1. Build a Foundation with Study Materials (3-4 weeks): Begin with a comprehensive Server+ study guide covering all four exam domains. Focus on server hardware concepts (RAID levels, storage technologies, processor architectures), as these form the basis for understanding administration and troubleshooting topics. Create reference sheets for RAID configurations, port numbers, and troubleshooting methodologies. Supplement reading with video courses that demonstrate real-world server scenarios and hardware installations.
2. Complete Hands-On Labs with Real or Virtual Servers (3-4 weeks): Performance-based questions (PBQs) test practical skills in simulated environments, making hands-on experience critical. Set up a home lab using VMware Workstation or VirtualBox to practice Windows Server and Linux installations, RAID configuration, backup implementation, and network setup. If you have access to physical server hardware (even decommissioned equipment), practice component installation, BIOS/UEFI configuration, and hardware diagnostics. Practice using remote management interfaces (iLO, iDRAC) and command-line administration tools.
3. Complete 500+ Practice Questions with Domain Focus (2-3 weeks): Work through practice question banks focusing on your weakest domains. Server+ questions often present troubleshooting scenarios requiring systematic problem-solving, so practice identifying the correct troubleshooting methodology steps (identify the problem, establish a theory, test the theory, establish a plan, implement the solution, verify functionality, document findings). Track your scores by domain and dedicate extra study time to areas below 80%.
4. Review and Take Full-Length Practice Exams (final 2 weeks): In the final two weeks, take at least 2-3 full-length timed practice exams (90 minutes, 90 questions) under exam conditions. Review the CompTIA Server+ Exam Objectives document to ensure complete coverage. Pay special attention to Troubleshooting (28%) and Server Administration (30%) as they represent the majority of exam content. Review the official CompTIA Server+ page for current exam objectives and format details.

Server+ test-taking strategy: for troubleshooting questions, always follow the CompTIA troubleshooting methodology rather than jumping to solutions. For hardware questions, pay attention to specifications and compatibility requirements. Budget 200-300 total study hours depending on your prior server experience.
