Picture a support technician two years into the job who has become the person the team calls when a rack-mounted host loses a drive: they can swap the disk, but rebuilding the RAID array, checking the firmware and explaining the risk to management is still guesswork. That gap — between touching servers and being trusted to run them — is precisely what CompTIA Server+ was built to certify.

Server+ is a vendor-neutral certification from CompTIA covering the installation, administration, security, disaster recovery and troubleshooting of physical and virtualised server infrastructure. One exam earns it: SK0-005. This guide is the complete candidate reference for that exam — scope, format, requirements, cost, the important 2025 renewal change, and how to prepare — and it deliberately leaves broader career-value debates and cert-versus-cert comparisons to their own articles.

The job Server+ certifies

Ask what a Server+ holder is supposed to be able to do and the answer is concrete: keep server hardware and operating systems alive in a data centre or on-premises server room. That means racking and cabling hardware, configuring storage — RAID levels, disk types, capacity planning — administering server operating systems, hardening them against attack, scripting routine tasks, planning backups and disaster recovery, and troubleshooting failures across hardware, storage, OS and network boundaries.

The certification is aimed at people in roles such as:

  • Server and systems administrators responsible for physical or virtualised server estates
  • Data centre technicians handling hardware installation, maintenance and decommissioning
  • Field service and support technicians whose remit is growing from desktops into the server room
  • IT operations staff in organisations that still run significant on-premises infrastructure — which, despite the cloud era, remains a very large share of the market

That last point frames who should not prioritise Server+. If your organisation's roadmap is aggressively cloud-first and your own ambitions point at cloud engineering, the vendor-neutral cloud credential is likely the better use of your next exam fee — our CompTIA Cloud+ certification guide covers that path. Server+ earns its keep where hardware is still something you can touch.

SK0-005 exam essentials

SK0-005 launched on 18 May 2021, which makes it the oldest live exam in CompTIA's current line-up, and as of August 2026 CompTIA has announced no successor. The practical implications: your study materials market is mature and stable, and there is no imminent version change to schedule around — but keep an eye on comptia.org, because exam versions retire on CompTIA's timetable.

Performance-based questions deserve emphasis: they drop you into a scenario — a degraded array, a boot failure, a misconfigured service — and score what you do rather than what you recall. Ninety minutes is not generous when several questions each take multiple minutes, so pacing needs to be rehearsed, not improvised.

What the objectives reward

CompTIA publishes the complete SK0-005 objectives free on comptia.org; download them before buying anything else. Read as a whole, they reward operational judgement over memorisation. Storage is a good example: the exam cares less about reciting RAID level definitions and more about choosing the right level for a redundancy and performance requirement, and knowing what actually happens — and what is at risk — during a rebuild. The same pattern holds for backup design (what does this recovery objective imply?), security hardening (which control mitigates this exposure?) and troubleshooting (what would you check first, and why?). If your study plan produces explanations rather than definitions, you are studying the way this exam is written.

Server+ requirements and cost

Requirements: none are enforced. Anyone can register for SK0-005. CompTIA's recommended profile — A+ or equivalent knowledge plus around two years working hands-on with servers — is the calibration point, and it is realistic. Candidates coming straight from desktop support without server exposure tend to find the storage and disaster-recovery domains abstract, because those topics only click once you have been responsible for data someone else cannot afford to lose.

Cost: CompTIA raised US retail prices across its portfolio in mid-2026, and a confirmed post-increase retail price for Server+ was not available at the time of this article's fact-check; the pre-increase US retail price was reported at $390. Treat that figure as historical context only and confirm the current fee for your country on the official Server+ page or through an authorised voucher reseller (whose discounts are legitimate) before budgeting. Also account for CompTIA's retake policy: a failed first attempt can be rebooked immediately, a third or later attempt requires a 14-day wait, and every sitting needs a full-price voucher unless you bought a retake bundle.

The renewal change every candidate should know about

For most of its history, Server+ was a "good for life" certification — pass once, hold it forever. That ended on 1 October 2025, when CompTIA moved Server+ (together with Project+) into its continuing education programme. A Server+ certification earned today is valid for three years and must then be renewed, like A+, Network+ or Security+.

Renewal works through the standard CompTIA CE routes: uploading continuing education units from training, work or community activity (Server+ sits in the $150-per-three-year-cycle fee tier when renewing this way); passing the latest version of the exam; or earning a higher-level CompTIA certification, which renews lower certifications automatically under CompTIA's stackable model — and you only pay CE fees for your highest cert. How the change applies to people certified before October 2025 has been described inconsistently in secondary sources, so if you hold an older Server+ credential, verify your own certification's status directly with CompTIA rather than relying on forum answers — including this caveat.

Factor the three-year cycle into your decision honestly: the true cost of Server+ is the voucher plus a renewal obligation, not the voucher alone. If you already maintain other CompTIA certifications, the marginal burden is small; if this would be your only cert, it is a recurring commitment you did not face under the old lifetime model.

How to prepare for SK0-005

A preparation sequence that matches how the exam is built:

  1. Objectives first. Download the SK0-005 objectives and mark every line: solid, shaky or unknown. This map drives everything else.
  2. Pick one structured resource — a current SK0-005 study guide or video course — and complete it, reconciling each chapter against your objectives map.
  3. Get hands on cheap hardware or a virtual lab. A retired tower server, or even hypervisor software on a desktop, lets you practise OS installs, RAID configuration (software RAID counts for learning), user and permissions management, backup jobs and deliberate break-fix exercises. The performance-based questions are far easier if your hands have done these tasks.
  4. Turn weak domains into projects. Shaky on disaster recovery? Design and actually test a backup-and-restore plan for your lab. Shaky on security? Harden a fresh install against a checklist. Topic-specific practice beats another read-through.
  5. Benchmark before you book. Practice questions are a diagnostic, not a shortcut: score yourself by domain, analyse every miss until the reasoning is yours, and never drill answer patterns into memory — the live exam rewords everything anyway. ExamPractice hosts free sample questions for the SK0-005 Server+ exam, with fuller sets and a timed simulation mode for subscribers; a timed full run under the 90-minute limit is the best readiness signal you can get before paying for a sitting.

Mistakes that cost Server+ candidates marks

  • Studying hardware only. The exam spans OS administration, security, DR and troubleshooting; candidates from hardware-heavy roles often under-prepare the administrative domains.
  • Memorising RAID tables without scenarios. Knowing RAID 5 uses parity is recall; knowing when it is the wrong choice is what gets tested.
  • Ignoring the scripting and automation content. Modern server administration assumes basic scripting literacy, and the objectives reflect that.
  • Booking on momentum. Finishing a course feels like readiness. Domain-level benchmark scores are readiness.

Frequently asked questions

Is Server+ an entry-level certification?

No — it is a step above entry level. With a recommended background of A+ plus two years of server experience, it pitches at early-career professionals consolidating into infrastructure roles. Complete beginners should start with the core certifications; our overview of which CompTIA certification to start with explains that sequencing in one place.

Is CompTIA Server+ worth it?

It depends on your environment. Server+ is worth pursuing when your role — or the role you want — involves genuine responsibility for physical or virtualised server infrastructure, when your employer values vendor-neutral credentials, or when it slots into a CompTIA stack you already maintain. It is worth skipping when your career direction is cloud-native or when your target employers' job adverts never mention on-premises infrastructure at all.

Can I sit the exam from home?

Yes. SK0-005 is delivered through Pearson VUE, and the OnVUE option allows online proctored testing from home, subject to Pearson's identity and testing-environment rules.

Does SK0-005 have a scheduled retirement date?

Not as of August 2026 — no successor exam has been announced. Check the official Server+ page when you begin studying, since CompTIA typically signals version transitions months in advance.

Should Server+ be your next exam?

Say yes if the scenario that opened this guide sounds like your week: you are already near servers, you want the responsibility that comes with running them, and on-premises infrastructure is a real part of your employer's future. Say not-yet if you have never administered a server — build that foundation first — and say no if your path points squarely at the cloud instead. If it is a yes, the route is short and clear: pull the SK0-005 objectives, build the lab, close the gaps, benchmark with practice questions, and only then book. Current fees, languages and any version news live on CompTIA's official Server+ page — check them at booking time, not just at study time.
