NO.53 Which mdadm command creates a RAID-1 device consisting of two block volumes and one spare device?

mdadm -create /dev/md0 -level=5 -raid-devices=2 /dev/xvdd1 /dev/xvdd2 -spare-devices=1 /dev
/xvdd3

mdadm -create /dev/md0 -level=1 -raid-devices=2 /dev/xvdd1 /dev/xvdd2

mdadm -create /dev/md0 -level=1 -raid-devices=2 /dev/xvdd1 /dev/xvdd2 -spare-devices=1 /dev
/xvdd3

mdadm -create /dev/md0 -level=0 -raid-devices=2 /dev/xvdd1 /dev/xvdd2 -spare-devices=1 /dev
/xvdd3

The correct command to create a RAID-1 device (mirroring) consisting of two block volumes with one spare device is optionC:mdadm -create /dev/md0 -level=1 -raid-devices=2 /dev/xvdd1 /dev/xvdd2 -spare- devices=1 /dev/xvdd3.
* RAID Level 1:RAID-1, also known as mirroring, involves creating an exact copy (or mirror) of a set of data on two or more disks. This ensures data redundancy; if one disk fails, the other can still provide the data.
* mdadm Command Structure:Themdadmcommand is used to manage and monitor RAID devices on Linux. To create a new RAID array, the–createoption is used, followed by several parameters:
* /dev/md0: The name of the RAID device to be created.
* –level=1: Specifies RAID level 1 (mirroring).
* –raid-devices=2: Indicates the number of active devices (two in this case) to be used in the RAID array.
* /dev/xvdd1 /dev/xvdd2: The two block devices that will form the RAID-1 array.
* –spare-devices=1 /dev/xvdd3: Specifies one spare device (/dev/xvdd3). A spare device is used to automatically replace a failed device in the RAID array.
* Option Analysis:
* A.Incorrect because it specifies RAID level 5 (–level=5), which requires at least three devices and does not match the requirement for RAID-1.
* B.Incorrect because it does not include the–spare-devices=1option, meaning there is no spare device included in this configuration.
* C.Correct as it specifies RAID-1 (–level=1), two active devices (–raid-devices=2), and one spare device (–spare-devices=1).
* D.Incorrect because it specifies RAID level 0 (–level=0), which is a striped set (no redundancy), not a mirrored set (RAID-1).
Oracle Linux Reference:For more detailed information aboutmdadmand RAID configurations in Oracle Linux
8, refer to the following Oracle Linux documentation:

NO.54 Which two statements are true about control groups (cgroups) in Oracle Linux 8?

Oracle Linux 8 implements cgroups v2 by default.

A cgroup is a collection of processes bound to a set of limits or parameters defined in the cgroups filesystem.

Different controllers from cgroups version 1 and cgroups version 2 cannot be used at the same time.

The cgroups filesystem allows limits to be overwritten in the lower levels of the hierarchy.

Cgroups allow processes to be organized into hierarchical groups whose resource usage cannot be limited and monitored.
