CompTIA Server+ SK0-005 CompTIA Study Notes

The step that the server administrator should perform before resolving the issue is to determine the probable causes. This step is part of the troubleshooting process that follows a logical and systematic approach to identify and solve problems with servers and applications. The troubleshooting process consists of several steps, such as:

• Identify the problem: Gather information from various sources, such as users, logs, or alerts, to understand the symptoms and scope of the problem.
• Establish a theory of probable cause: Analyze the information and formulate one or more possible causes of the problem based on evidence or experience.
• Test the theory to determine cause: Perform tests or experiments to verify or eliminate each possible cause until the root cause is found.
• Establish a plan of action to resolve the problem and implement the solution: Design and execute a plan to fix the problem using appropriate tools and techniques.
• Verify full system functionality and implement preventive measures: Confirm that the problem is resolved and that no other issues arise as a result of the solution. Implement preventive measures to avoid recurrence of the problem or improve performance.
• Document findings, actions, and outcomes: Record the details of the problem, its cause, its solution, and its outcome for future reference or knowledge sharing. References: [CompTIA Server+ Certification Exam Objectives], Domain 6.0: Troubleshooting, Objective 6.1: Given a scenario involving server hardware issues (e.g., power supply failure), troubleshoot using appropriate tools.

According to the CompTIA troubleshooting methodology, the fourth step is to establish a plan of action to resolve the problem and implement the solution1. The best practice is to test each solution individually to determine the root cause, rolling back the changes in between each test. This way, the technician can isolate the cause and avoid introducing new problems or making the situation worse. Testing each solution in succession and restoring the server from the latest snapshot (D) is not a good option because it may not identify the root cause and may overwrite important data. Implementing the shortest solution first to identify the issue and minimize downtime © is also not a good option because it may not solve the problem or may create new issues. Consulting internet forums to determine which is the most common cause and deploy only that solution (A) is not a good option because it may not apply to the specific situation or may be outdated or inaccurate

Applying security updates is one of the common operating system hardening methods that can help protect the OS from cyberattacks and vulnerabilities. Security updates are released by the OS developer to fix bugs, patch security holes, and improve performance. By installing the latest updates, the server administrator can ensure that the OS is up to date and secure12.

PowerShell is a scripting language and a command-line shell that uses commands that start with sec- to perform security-related tasks. For example, sec-edit is a command that edits security policies, sec-logon is a command that manages logon sessions, and sec-policy is a command that applies security templates.
