CompTIA Server+

The exam has a maximum of 90 questions and a 90-minute time limit. That works out to roughly one minute per question, so performance-based items that require several steps can consume far more time than a single multiple-choice question. Practicing under a timer is worthwhile.

The passing score is 750 on a scale of 100-900. Because the reported score is scaled rather than a raw percentage, you cannot simply count correct answers to predict a pass. Aim to be comfortably consistent across all four domains rather than strong in just one.

There is no enforced prerequisite. CompTIA lists recommended experience of A+ certification or equivalent knowledge, with two years of hands-on experience in a server environment. Candidates without that background can still sit the exam, but they typically need more study time to cover storage, networking and operating system fundamentals.

Server administration is the largest at 30%, followed by troubleshooting at 28%, so those two account for well over half the exam. Security and disaster recovery is 24% and hardware is 18%. A sensible order is hardware first for physical context, then administration, then security, then troubleshooting, which draws on all three.

The exam uses multiple choice and performance-based questions, per CompTIA's exam details. Performance-based items ask you to carry out a task or make a sequence of decisions rather than pick a single option, so hands-on familiarity with server consoles, storage configuration and command-line tools matters more than memorization.

The exam is offered in English and Japanese at Pearson VUE testing centers and through online testing. Online delivery means you should check your equipment, room and identification requirements ahead of time; a testing-environment problem on exam day is far more disruptive than the exam content itself.

CompTIA does not publish a pass rate in its exam details, so difficulty is best judged by breadth: four domains spanning physical hardware, operating systems, networking, virtualization, security and disaster recovery. Candidates with only desktop support experience usually find storage, clustering and recovery objectives the steepest material.

Two patterns dominate. First, over-preparing on hardware trivia because it feels concrete, while neglecting administration and troubleshooting, which together carry 58% of the weight. Second, reading without touching equipment, which leaves candidates unable to reason through performance-based tasks involving RAID selection, partitioning or failover validation.

CompTIA lists the NICE and DCWF work roles of network operations specialist and systems administrator. That mapping is a useful guide to the job expectations the exam reflects: day-to-day server operations, monitoring, access control, patching and recovery rather than architecture or application development.

Use the domain weights to allocate time: about a third on administration, a quarter each on troubleshooting and security, and the remainder on hardware. Finish with timed practice exams and review every missed item back to the underlying objective, especially in troubleshooting where scenario reasoning is required.
