Understand the certification
认证概述
CompTIA Server+（SK0-004）验证你在物理服务器全生命周期管理上的实战能力：从硬件安装、存储配置，到虚拟化部署、安全加固，再到故障诊断排查。这是数据中心技术员晋升服务器管理员、或政府 IT 岗位满足 DoD 8570 合规要求时最常被要求持有的认证之一。SK0-004 于 2021 年底退役，但题库仍被部分考试中心提供，通过后获得与 SK0-005 相同的 CompTIA Server+ 认证。
考试领域
- 服务器架构（Server Architecture）— 18%：服务器硬件组件选型、机架安装规范、服务器类型对比（Tower/Rack/Blade/Multinode）
- 服务器管理（Server Administration）— 30%：操作系统安装与配置、Active Directory 集成、远程管理工具（IPMI/iDRAC/iLO）、备份与恢复策略
- 安全（Security）— 20%：物理安全控制、访问权限管理、防火墙配置、安全审计日志与合规
- 故障排除（Troubleshooting）— 32%：硬件故障诊断方法论、RAID 降级与重建、存储连接排查（iSCSI/FC）、网络连通性故障定位
适合人群
数据中心技术员（Data Center Technician）、服务器管理员（Server Administrator）或系统工程师（Systems Engineer），以及政府和国防 IT 岗位需满足 DoD 8570 合规的从业者。持有 CompTIA A+ 并想向服务器专方向深入的 IT 工程师，这是最直接的进阶路线。

Before you register
What does the CompTIA Server+ (SK0-004) exam cover?
SK0-004 tests the full lifecycle of server hardware, software, and operations management. Key domains include: Server Architecture (18%), Server Administration (30%), Security (20%), and Troubleshooting (32%). Troubleshooting has the highest weight, focusing on hardware fault diagnosis, storage issue resolution, and network connectivity troubleshooting.
What is the difference between SK0-004 and SK0-005? Which should I take?
SK0-004 is the older version of Server+, while SK0-005 is the current latest version. SK0-005 adds modern data center technologies including cloud computing, virtualization, and containerization. If your testing center still offers SK0-004, both versions yield the same certification. It is recommended to prioritize the latest version SK0-005.
What prerequisites are needed for Server+?
CompTIA A+ equivalent IT foundational knowledge and 18-24 months of server administration hands-on experience is recommended. You should understand RAID configuration, server virtualization (VMware/Hyper-V), Active Directory basics, and fundamental networking concepts (DNS, DHCP, TCP/IP).
Does Server+ certification require renewal?
CompTIA Server+ certification is valid for life once earned and does not require renewal or continuing education credits. This differs from CompTIA certifications like Security+ and Network+ that require renewal every three years, making it a one-time investment with lifelong benefits.
How does Server+ certification help career development?
Server+ certification targets data center technicians, server administrators, and systems engineers. It holds DoD 8570 approval and is widely recognized in government and defense sectors. Certified professionals typically work as server administrators, data center technicians, or systems engineers with strong employment competitiveness.
