Q

OBJ-3.1: The Boot Configuration Data (BCD) stores the list of known Windows installations that can be booted from a hard drive. If the Windows installation is not listed, the computer will be unable to boot into Windows. To add a missing Windows installation to the Boot Configuration Database (BCD), you should use the command “_____” and reboot the computer. If the disk cannot be detected, enter the system setup and try modifying settings (or even resetting the default settings). If the system firmware reports the disk’s presence, but Windows still will not boot, use a startup repair tool to open a recovery mode command prompt and use the bootrec tool to repair the drive’s boot information. The “bootrec /fixmbr” command is used to attempt a repair of the master boot record of a drive

Q

backup rotation scheme is widely used to combine full and incremental backups to reduce backup time and enhance storage security.

A

GFS
For example, each Monday a full backup can be conducted which becomes the father. Then, each day of the week a son is created by performing an incremental or differential backup. Once per month, a full backup is conducted to become the grandfather. The grandfather is a full backup that is stored off-site once per month. The father is a weekly full backup that is conducted. The son is an incremental or differential backup conducted each day

Q

a backup rotation scheme that rotates backup media sets throughout the backup process to minimize wear and failure of tape backup media.

A

The Tower of Hanoi
For example, when using this method with four backup tapes labeled A, B, C, and D, a total of 16 days of backups can be maintained with just 4 tapes. Tape A is used every odd-numbered day for 16 days. Tape B is used on days 2, 6, 10, and 14. Tape C is used on days 4 and 12. Tape D is used on days 8 and 16. This allows Tape A to be overwritten every other day, while Tapes B is overwritten every four days and Tapes C and D are overwritten every 8 days.
Which of the following backup rotation schemes uses a complex mathematical puzzle to extend the number of unique days of backups stored with the least amount of tapes?

Q

Control Panel allows technicians to customize how a computer manages its power to either conserve energy at the expense of performance or to maximize performance at the expense of energy savings by creating a power plan. The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is helpful when using a laptop computer as it helps to conserve battery power by powering off USB ports that are not needed at the time.

A

Jason wants to configure his Windows 10 laptop to suspend individual USB ports when not in use. Which of the following Control Panel sections should he use to set the USB selective suspend feature?
The USB selective suspend feature is located in the Power Options section of the Control Panel. Power Options

Q

Your company wants to provide a secure SSO solution for accessing both the corporate wireless network and its network resources. Which of the following technologies should be used?

A

With RADIUS and SSO configured, users on the network can provide their user credentials one time when they initially connect to the wireless access point or another RADIUS client and are then automatically authenticated to all of the network’s resources. The Remote Authentication Dial-in User Service (RADIUS) is used to manage remote and wireless authentication infrastructure. Users supply authentication information to RADIUS client devices, such as wireless access points. The client device then passes the authentication data to an AAA (Authentication, Authorization, and Accounting) server that processes the request. The Terminal Access Controller Access Control System (TACACS+) is a proprietary alternative to RADIUS developed by Cisco for handling authentication
