KHS CompTIA Fundamentals: Domain 2

Which of the following strategies would be most effective in troubleshooting a computer that frequently crashes?

• Reinstall the operating system without checking for hardware issues.

• Check the event logs for error messages and test the hardware components.

• Replace the power supply without testing other components.

• Upgrade the RAM without diagnosing the problem.

Answer explanation

Checking event logs for error messages and testing hardware components is crucial for identifying the root cause of crashes. This approach ensures that both software and hardware issues are addressed, leading to effective troubleshooting.

A user reports that their computer is running slowly. Which of the following plans would best address this issue?

• Install more RAM without checking current usage.

• Analyze the task manager to identify resource-heavy applications and consider upgrading hardware if necessary.

• Replace the hard drive without checking for software issues.

• Reboot the computer and hope the issue resolves itself.

Answer explanation

Analyzing the task manager helps identify which applications are using the most resources. This approach allows for targeted solutions, such as closing programs or upgrading hardware, rather than making assumptions without data.

When planning a backup strategy for a small business, which of the following considerations is most important?

• The color of the backup devices.

• The frequency of backups and the criticality of data.

• The brand of the backup software.

• The number of employees in the company.

Answer explanation

The frequency of backups and the criticality of data are crucial for ensuring data integrity and availability. Regular backups protect against data loss, while understanding data importance helps prioritize resources effectively.

A student needs to create a presentation on cybersecurity threats. Which of the following approaches would be most effective?

• Copying and pasting information from the internet without understanding it.

• Researching various threats, analyzing their impact, and suggesting preventive measures.

• Using only one source for all information.

• Focusing solely on viruses and ignoring other types of threats.

Answer explanation

The most effective approach is to research various cybersecurity threats, analyze their impact, and suggest preventive measures. This ensures a comprehensive understanding and equips the audience with actionable insights.

Which of the following is the best method to ensure data integrity during data transfer?

• Using a USB drive without any encryption.

• Implementing checksums or hash functions to verify data accuracy.

• Sending data over an unsecured network.

• Compressing data to save space without checking integrity.

Answer explanation

Implementing checksums or hash functions ensures data integrity by allowing verification of data accuracy during transfer, making it the best method compared to other options that lack security or integrity checks.

A company wants to improve its network security. Which of the following strategies should they prioritize?

• Installing antivirus software on all computers.

• Developing a comprehensive security policy and conducting regular security audits.

• Allowing unrestricted access to all network resources.

• Using outdated security protocols.

Answer explanation

Developing a comprehensive security policy and conducting regular security audits are essential for identifying vulnerabilities and ensuring ongoing protection, making it a priority for improving network security.

How should a student approach learning a new programming language effectively?

• Memorizing code without understanding its logic.

• Practicing coding by working on small projects and understanding the underlying concepts.

• Only reading books without writing any code.

• Watching tutorials without any hands-on practice.

Answer explanation

The best approach to learning a new programming language is by practicing coding through small projects. This method helps students grasp underlying concepts, making them more effective and confident in their programming skills.

Which of the following is the most strategic approach to managing software updates in an organization?

• Ignoring updates until a problem arises.

• Regularly reviewing and applying updates after testing them in a controlled environment.

• Applying updates immediately without any testing.

• Only updating software once a year.

Answer explanation

The most strategic approach is to regularly review and apply updates after testing them in a controlled environment. This minimizes risks and ensures stability, unlike ignoring updates or applying them without testing.

What is the best way to ensure that a new software application meets user needs?

• Developing the application without any user feedback.

• Conducting user surveys and usability testing during the development process.

• Assuming that the developers know what users need.

• Releasing the application without any testing.

Answer explanation

The best way to ensure a software application meets user needs is by conducting user surveys and usability testing during development. This approach gathers direct feedback, allowing for adjustments that align the application with user expectations.

A student is tasked with creating a network diagram for a school project. What is the most effective way to approach this task?

• Drawing random lines and labeling them as network components.

• Researching network components, planning the layout, and using diagramming software to create an accurate representation.

• Copying a diagram from the internet without understanding it.

• Using only text to describe the network.

Answer explanation

The most effective approach involves researching network components, planning the layout, and using diagramming software. This ensures an accurate and clear representation, unlike random drawings or copying without understanding.
