CompTIA Updated SK0-005 Exam Questions and Answers by nikolas

The concept of authentication is rooted in the principle of verifying identity, which is commonly broken down into three categories: "something you know" (like a password or PIN), "something you have" (such as a smart card or a security token), and "something you are" (biometric data, for example, fingerprints). The question asks for the authentication type defined by "something you have."

Off-site storage involves storing data backups in a physically separate location from where the servers and primary data reside. This protects critical data in case the main site is damaged or destroyed due to a natural disaster, such as floods, fires, or earthquakes. Off-site storage can be in the form of cloud storage or physical tapes stored in a geographically distant location.

Off-site storage (Answer A): It ensures that a company's critical data remains accessible even if the local infrastructure is compromised. This is a common part of disaster recovery planning and is crucial for business continuity.

Life-cycle management (Option B): While important for managing data from creation to deletion, it does not specifically protect data during disasters.

Environmental controls (Option C): These manage physical conditions like temperature and humidity but do not address the risk of data loss during disasters.

Data-at-rest encryption (Option D): Encryption protects the confidentiality of stored data but does not ensure availability in the event of a disaster.

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:The fs> prompt typically indicates that the Unified Extensible Firmware Interface (UEFI) has entered the EFI shell due to a failure in locating the bootloader or a critical Linux boot file. This often occurs after an update where boot files are moved, renamed, or deleted. To resolve:

Verify the bootloader configuration (e.g., GRUB) and ensure the correct partition is set for booting.

Recreate or repair the bootloader files if necessary.

Ensure the boot sequence in UEFI settings points to the correct disk and partition.

Other options:

A. USB flash drive booting: Unlikely unless the boot order was unintentionally altered.

C. BIOS not finding a bootable hard disk: Would generally result in a different error message.

D. BIOS firmware upgrade: Not typically required for this specific issue.

The next step to troubleshoot the issue after developing and testing a theory is to establish an action plan. This involves identifying the steps needed to implement the solution, estimating the time and resources required, and evaluating the potential risks and impacts of the solution. Documenting the findings and actions, escalating the issue to the management team, or implementing the solution are steps that should be done after establishing an action plan. References: [CompTIA Server+ Certification Exam Objectives], Domain 6.0: Disaster Recovery, Objective 6.2: Explain troubleshooting theory and methodologies.
