CompTIA Updated N10-009 Exam Questions and Answers by claudia

Confidentiality with Data at Rest: Confidentiality is a core principle of data security, ensuring that data stored (at rest) is only accessible to authorized individuals. This protection is achieved through mechanisms such as encryption, access controls, and permissions.

Privileged Access: The statement "Data can be accessed after privileged access is granted" aligns with the confidentiality principle, as it restricts data access to users who have been granted specific permissions or roles. Only those with the appropriate credentials or permissions can access the data.

Incorrect Options:

A. "Data can be accessed by anyone on the administrative network." This violates the principle of confidentiality by allowing unrestricted access.

B. "Data can be accessed remotely with proper training." This focuses on remote access rather than restricting access based on privileges.

D. "Data can be accessed after verifying the hash." This option relates more to data integrity rather than confidentiality.

Unshielded cables (D) are more prone to interference and may not be suitable for certain environments, especially after a fire where interference could be heightened.

Using the wrong transceiver (E) for new terminations can lead to compatibility issues, causing network failures.

Once the theory has been tested and confirmed, the next step is to implement the solution based on the CompTIA troubleshooting model.

CompTIA Troubleshooting Model:

Identify the problem.

Establish a theory of probable cause.

Test the theory.

Establish a plan of action and implement the solution. ✅ (Correct step)

Verify full system functionality.

Document findings, actions, and outcomes.

Breakdown of Options:

A. Develop a theory – The theory has already been developed and tested.

B. Establish a plan of action – This happens before implementation, but since the issue is confirmed, it's time to act.

C. Implement the solution – Correct answer. The problem is confirmed, so the fix should be applied.

D. Document the findings – Documentation is the final step, not the next one.

A warm site typically has a full infrastructure ready, but it lacks the most up-to-date data or is not immediately operational. It requires some configuration or data restoration to become fully functional.
