Comprehensive and Detailed Explanation From Exact Extract:
Virtualization settings are typically found within the BIOS/UEFI firmware configuration. To prevent unauthorized users from changing these settings, the technician should set a BIOS password. This ensures only administrators with the password can access or modify BIOS settings, including virtualization support.
B). The guest account is a user-level feature in Windows and doesn't control BIOS access.
C). A screen lock prevents casual access to the desktop but doesn't protect firmware settings.
D). AutoRun controls how media and devices behave when inserted - unrelated to BIOS security.

The correct answer is A. Detailed guides for resolving common issues, because effective deployment documentation must support ongoing troubleshooting and support, not just initial installation. Including known issues and resolution steps allows future technicians to resolve problems efficiently and consistently.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, high-quality technical documentation should include error conditions, common failure points, and step-by-step remediation procedures. This information significantly reduces mean time to resolution (MTTR) and improves service quality.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that help desk documentation should evolve over time, incorporating lessons learned from previous incidents. Troubleshooting guides turn deployment documentation into a practical reference rather than a static record.
The Mike Meyers / Mark Soper Lab Manual further clarifies that email logs are informal and unstructured, vendor contact information is supplementary, and end-user manuals are not intended for technical troubleshooting. None of these provide actionable guidance for technicians resolving future issues.
Because the goal is to ensure long-term supportability and effective troubleshooting, the most important inclusion is detailed guides for resolving common issues, making A the correct answer.

Azero-day vulnerabilitydemands an emergency change to quickly secure the system, even if downtime is needed.
FromMike Meyers' Lab Manual:
"Emergency changes bypass standard scheduling to quickly address critical vulnerabilities that pose immediate risks." .

TheLocal Users and Groups Manager (lusrmgr.msc)is the utility for managing user accounts, including renaming the default Administrator.
FromQuentin Docter - Complete Study Guide:
"The lusrmgr.msc snap-in allows renaming and managing local user accounts, including the default administrator." .

Standard Operating Procedures (SOPs) define the mandatory steps and expectations technicians must follow during support calls. This includes documentation standards such as logging user info, asset details, and issue descriptions in the ticketing system. Implementing SOPs ensures consistency and accountability.
A: SLAs define response/resolution times but not documentation practices.
B: Call categories organize types of issues but don't guide technician actions.
D: Knowledge base articles provide solutions to known problems but don't ensure proper ticket documentation.
