You have a server named Server1 that runs Windows Server 2012 R2.
Server1 fails.
You identify that the master boot record (MBR) is corrupt.
You need to repair the MBR.
Which tool should you use?
A.
Bcdedit
B.
Bcdboot
C.
Bootrec
D.
Fixmbr
Explanation:
Repairing an unbootable Windows installation with bootrec.exe If the boot/recovery partition is corrupted or lost,
you can modify your Windows OS partition to boot.
Boot from your Windows Vista/7/Server2008/R2/2012 media and choose the “Repair Windows” option.
Open the command prompt.
Using diskpart, mark your Windows partition as bootable.
If your windows partition does not have it, copy the “boot” folder from the installation media.
Run the following commands:
>c:
>cd boot
>attrib bcd -s -h -r
>ren c:\\boot\\bcd bcd.old
>bootrec /RebuildBcd
Reboot and Windows should boot normally. If not, return to the command prompt and run:
>bootrec /FixMBR
>bootrec /FixBoot
Incorrect:
Not A. BCDEdit is a command-line tool for managing BCD stores. It can be used for a variety of purposes,
including creating new stores, modifying existing stores, adding boot menu options, and so on. BCDEdit serves
essentially the same purpose as Bootcfg.exe on earlier versions of Windows
Not B. The BCDboot tool is a command-line tool that enables you to manage system partition files
Not D. Fixmbr is not a tool. Fixmbr is an option when using the bootrec tool.

I really want to say the answer is
B: BCDboot
In the measure up tests they really heavily make sure you understand BCDBoot is used for windows 2012 R2
Bootrec does work, but BCDBoot is new with 2012 and does the same sort of things.

BCDBoot is a command-line tool used to configure the boot files on a PC or device to run the Windows operating system. You can use the tool in the following scenarios:
Add boot files to a PC after applying a new Windows image. In a typical image-based Windows deployment, use BCDBoot to set up the firmware and system partition to boot to your image. To learn more, see Capture and Apply Windows, System, and Recovery Partitions.
Set up the PC to boot to a virtual hard disk (VHD) file that includes a Windows image. To learn more, see Boot to VHD (Native Boot): Add a Virtual Hard Disk to the Boot Menu.
Repair the system partition. If the system partition has been corrupted, you can use BCDBoot to recreate the system partition files by using new copies of these files from the Windows partition.
Set up or repair the boot menu on a dual-boot PC. If you’ve installed more than one copy of Windows on a PC, you can use BCDBoot to add or repair the boot menu.

Correct!
BootRec.exe /fixmbr
you can also substitue the /fixmbr with thes commands:
/FixBoot. Writes a boot sector onto the system partition to start Windows
/ScanOs. Scans all disks for Windows installations and displays them to you.
/RebuildBcd. Scans all disks for Windows installations and prompts you to pick the ones you want to add to the BCD.
