The CompTIA Server+ Certification Exam (SK0-005) is designed for IT professionals who manage, maintain, and troubleshoot server environments in production settings. This certification validates your ability to handle server administration, hardware management, security, and disaster recovery tasks that are critical to organizational infrastructure. Whether you're advancing your career or strengthening your technical foundation, this page provides a clear roadmap of what to study and how to prepare effectively. The SK0-005 exam tests both theoretical knowledge and practical decision-making skills that apply directly to real-world server operations.
Use this topic map to guide your study for CompTIA SK0-005 (CompTIA Server+ Certification Exam) within the CompTIA Server+ path.
The SK0-005 exam measures both foundational knowledge and the ability to apply that knowledge to real-world scenarios. You'll encounter a mix of question types that progressively increase in complexity and require practical reasoning.
Questions build in difficulty and emphasize the ability to connect concepts across administration, hardware, security, and troubleshooting workflows that occur in live environments.
An effective study plan breaks the SK0-005 syllabus into manageable weekly goals and combines passive learning with active practice. Allocate time proportionally to each domain, prioritize weak areas, and simulate exam conditions in your final week.

Server Administration and Troubleshooting typically account for the largest portion of the exam, reflecting their importance in daily server operations. However, all four domains are tested, and questions often blend multiple topics, for example, a troubleshooting scenario may require knowledge of hardware and security. Balance your study time across all domains, but allocate extra practice to administration and troubleshooting scenarios.
In production environments, these domains overlap continuously. You might install new hardware (Hardware Installation), configure it within your directory service (Administration), enable encryption and backups (Security and Disaster Recovery), and then monitor performance and resolve issues (Troubleshooting). Understanding these connections helps you answer scenario questions and apply knowledge to unfamiliar situations on exam day.
CompTIA recommends at least 1-2 years of hands-on server administration experience before attempting SK0-005. If you have less experience, prioritize lab work on tasks like user provisioning, RAID configuration, backup procedures, and performance monitoring. Even simulated lab environments help you understand the concepts tested and build confidence with real tools.
Many candidates misread scenario questions and choose technically correct answers that don't fit the specific context, for example, selecting a secure solution when the question asks for the fastest recovery option. Others overlook the "best" qualifier in multi-correct scenarios. Read each question twice, note any constraints (time, budget, risk tolerance), and eliminate answers that don't address the stated problem.
Review your practice test results and identify topics where you scored below 75%; spend 2-3 days drilling those areas with focused questions. In the last 2-3 days, take one full-length timed practice test to build stamina and confirm your pacing. Avoid cramming new material; instead, review key definitions, RAID types, backup strategies, and common troubleshooting workflows to keep them fresh in memory.
The management team has requested that new software licenses be purchased out of the capital budget as one-time, non-renewing expenses this year. Which of the following types of software licenses would most likely be used to meet this request?
Aperpetual licenseis a one-time purchase that allows the software to be used indefinitely without recurring costs. This meets the requirement of a non-renewing, one-time capital expense.
Perpetual (Answer D):This is a one-time purchase and does not require renewal, making it ideal for capital expenditure.
Open-source (Option A):Open-source software is usually free but may not meet specific licensing requirements.
Subscription (Option B):This typically involves recurring payments, which contradicts the non-renewing expense requirement.
Volume (Option C):Volume licenses are used for purchasing multiple licenses at a discount but may still involve subscription-based renewals.
CompTIA Server+ Reference:This topic is covered underSK0-005 Objective 2.1: Explain licensing concepts for software.
An administrator discovers a Bash script file has the following permissions set in octal notation;
777
Which of the following is the MOST appropriate command to ensure only the root user can modify and execute the script?
chmod is a command-line tool that changes the permissions of files and directories in Linux and Unix systems. chmod go-rwx means to remove read, write, and execute permissions for group and other users from a file or directory. This can ensure only the root user can modify and execute the script, since root user has full access to all files and directories regardless of their permissions.

Due to a disaster incident on a primary site, corporate users are redirected to cloud services where they will be required to be authenticated just once in order to use all cloud services.
Which of the following types of authentications is described in this scenario?
Which of the following should be created to understand how long data is stored and how frequently data backups should be scheduled?
Retention policiesdefine how long data should be kept before being archived or deleted and help in determining the frequency of backups to ensure data is available when needed. These policies are crucial for compliance, storage management, and disaster recovery planning.
Retention policies (Answer A):These directly address how long data is kept and how often it should be backed up.
Service-level agreement (Option B):SLAs define performance expectations and uptime, not specific data retention or backup schedules.
Life-cycle management (Option C):This refers to managing data from creation to disposal but doesn't specifically address backup frequency or retention periods.
Mean time to recover (Option D):This metric measures how long it takes to restore services after a failure, not backup scheduling.
CompTIA Server+ Reference:This topic relates toSK0-005 Objective 4.2: Explain the importance of data security concepts.
A technician replaces a single faulted disk in the following array RAID 10, Four 15K SAS HDD The technician replaces it from a disk in spare parts, and the array rebuilds the data in a few minutes. After the array rebuild is complete, the system reports the IOPS on the disk array have dropped by almost 60% Which of the following should the technician investigate first?
In RAID 10 arrays, disk performance is crucial, especially if they are high-speed 15K RPM SAS HDDs, as each disk in the array is part of a mirrored pair that also stripes data with another pair. When replacing a disk, it's essential that the new disk matches the specifications of the others, especially in terms of rotational speed (RPM). If the replaced disk is slower, it can significantly reduce the Input/Output operations per second (IOPS) of the entire array. This is because all disks need to work in tandem, and the slowest disk can become a bottleneck. Thus, checking the RPM of the newly replaced disk is a sensible first step to ensure it matches the performance of the other disks in the array.
