After using a third-party disk optimization software package, a technician restarts a laptop and receives the message ''No operating system found.'' The technician verifies that the BIOS properly recognizes the SSD. Which of the following should the technician do next?
Comprehensive and Detailed Explanation From Exact Extract:
Disk optimization tools can sometimes corrupt theMaster Boot Record (MBR). If BIOS sees the drive but can't boot, repairing the MBR using installation media is the correct next step.
FromAll-in-One Exam Guide:
''When BIOS recognizes the drive but no OS is found, the issue is often with the boot record. Use installation media to access recovery tools and repair the MBR or boot loader.''
A Windows 11 Home device is receiving constant pop-ups about an urgent need to update antivirus software in order to remove a detected threat. The user has been clicking the "X" button but the window keeps reappearing. The pop-up includes an "OK" button to install the update. What should the user do next?
Comprehensive and Detailed Explanation From Exact Extract:
Persistent pop-ups urging antivirus updates are likelyscareware or adware. The correct approach is toverify existing antivirus settings, run a trusted security scan, and avoid interacting with unknown pop-ups.
FromQuentin Docter -- CompTIA A+ Complete Study Guide:
''Users should verify antivirus status using trusted tools before responding to alerts. Fake updates are common vectors for malware.''
A help desk technician needs to remove RAM from retired workstations and upgrade other workstations that have applications that use more memory with this RAM. Which of the following actions would the technician most likely take?
Comprehensive and Detailed Explanation From Exact Extract:
RAM is an electrostatic-sensitive component. When removing or transporting RAM modules, they should be stored in antistatic bags to protect against electrostatic discharge (ESD), which can damage the memory. This is a standard best practice in hardware handling.
A . Demagnetization is not applicable to RAM.
C . Plugging in power to ground is not safe or recommended for static protection.
D . Installing identical memory pairs is applicable for dual-channel configuration, but not directly related to transporting or handling RAM.

Which of the following is found in an MSDS sheet for a battery backup?
Comprehensive and Detailed Explanation From Exact Extract:
An MSDS (Material Safety Data Sheet), now commonly referred to as SDS (Safety Data Sheet), is a document that provides detailed information on the properties of a particular substance. It includes safety guidelines and emergency procedures related to handling, exposure, fire hazards, and first aid---not installation or configuration instructions.
For a battery backup (UPS device), the MSDS would include emergency procedures such as what to do in case of a chemical spill, exposure to battery acid, or fire hazard due to overheating or chemical leakage. This ensures the safety of personnel and complies with hazardous materials handling regulations.
CompTIA A+ 220-1102 Objective 4.1: Given a scenario, implement best practices associated with documentation and support systems information management.

A user reports that the time on their computer does not match the time on their VoIP phone. What should a technician do?
This scenario involves a mismatch in device time settings, which can affect synchronization and authentication across the network. Using a Network Time Protocol (NTP) server ensures all networked devices maintain accurate and synchronized clocks.
From Travis Everett -- All-in-One Exam Guide:
''NTP servers keep all devices on a network in sync. This prevents time drift, which can cause authentication issues with domain logins, certificates, and applications.'' .
