NEW QUESTION # 112
A developer's Type 2 hypervisor is performing inadequately when compiling new source code. Which of the following components should the developer upgrade to improve the hypervisor's performance?
- A. Amount of system RAM
- B. Storage IOPS
- C. NIC performance
- D. Dedicated GPU
Answer: A
Explanation:
Explanation
The amount of system RAM (random access memory) is a component that can affect the performance of a Type 2 hypervisor, which is a software program that runs on top of an existing operating system and allows multiple virtual machines to run simultaneously. The amount of system RAM determines how much memory is available for the hypervisor and the virtual machines to use. Increasing the amount of system RAM can improve the hypervisor's performance by allowing more memory allocation for each virtual machine and reducing the need for swapping or paging. NIC performance, storage IOPS, and dedicated GPU are not components that can directly improve the hypervisor's performance.

NEW QUESTION # 114
A technician is troubleshooting an issue with a computer that contains sensitive information. The technician determines the computer needs to be taken off site for repair. Which of the following should the technician do NEXT?
- A. Delete the sensitive information before the computer leaves the building.
- B. Check corporate polices for guidance.
- C. Remove the HDD and then send the computer for repair.
- D. Get authorization from the manager.
Answer: D
Explanation:
Explanation
The next step that the technician should do before taking the computer off site for repair is to get authorization from the manager. Getting authorization from the manager is important because it ensures that the technician has permission and approval to remove the computer from the premises and perform the repair work off site.
Getting authorization from the manager can also help document and communicate the reason and duration of the repair and avoid any misunderstanding or conflict with the user or the organization. Removing the HDD and then sending the computer for repair may not be feasible or necessary if the issue is not related to the HDD or if the HDD contains essential data or software for the repair. Checking corporate policies for guidance may be a good step but it does not replace getting authorization from the manager who is responsible for the computer and its data. Deleting the sensitive information before the computer leaves the building may not be possible or advisable if the issue prevents access to the data or if the data is needed for troubleshooting or recovery purposes.

NEW QUESTION # 116
A large company is selecting a new Windows operating system and needs to ensure it has built-in encryption and endpoint protection. Which of the following Windows versions will MOST likely be selected?
- A. Pro
- B. Pro for Workstations
- C. Enterprise
- D. Home
Answer: C

These features can help to protect the company's data and endpoints against malware attacks, unauthorized access, and data theft.
The Home and Pro editions of Windows do not include some of the advanced security features provided by the Enterprise edition, such as Windows Defender ATP and AppLocker. The Pro for Workstations edition is designed for high-performance and high-end hardware configurations, but it does not provide additional security features beyond those provided by the Pro edition.

Once the risks have been analyzed and the appropriate measures have been taken to minimize them, the change can be approved and implemented.
NEW QUESTION # 119
A computer on a corporate network has a malware infection. Which of the following would be the BEST method for returning the computer to service?
- A. Reinstalling the OS. flashing the BIOS, and then scanning with on-premises antivirus
- B. Degaussing the hard drive, flashing the BIOS, and then reinstalling the OS
- C. Scanning the system with a Linux live disc, flashing the BIOS, and then returning the computer to service
- D. Flashing the BIOS, reformatting the drive, and then reinstalling the OS
Answer: D
Explanation:
Flashing the BIOS, reformatting the drive, and then reinstalling the OS is the best method for returning a computer with a malware infection to service. Flashing the BIOS updates the firmware of the motherboard and can remove any malware that may have infected it. Reformatting the drive erases all data on it and can remove any malware that may have infected it. Reinstalling the OS restores the system files and settings to their original state and can remove any malware that may have modified them. Scanning the system with a Linux live disc may not detect or remove all malware infections. Degaussing the hard drive is an extreme method of destroying data that may damage the drive beyond repair. Reinstalling the OS before flashing the BIOS or scanning with antivirus may not remove malware infections that persist in the BIOS or other files.

A technician is in the process of installing a new hard drive on a server but is called away to another task. The drive has been unpackaged and left on a desk. Which of the following should the technician perform before leaving?
- A. Leave the hard drive on the table; it will be okay while the other task is completed.
- B. Connect an electrostatic discharge strap to the drive.
- C. Ask coworkers to make sure no one touches the hard drive.
- D. Place the hard drive in an antistatic bag and secure the area containing the hard drive.

Explanation
The technician should place the hard drive in an antistatic bag and secure the area containing the hard drive before leaving. This will protect the hard drive from electrostatic discharge (ESD), dust, moisture, and physical damage. Asking coworkers to make sure no one touches the hard drive is not a reliable or secure way to prevent damage. Leaving the hard drive on the table exposes it to ESD and other environmental hazards.
Connecting an electrostatic discharge strap to the drive is not enough to protect it from dust, moisture, and physical damage.
