NEW QUESTION # 18
Which mdadm command creates a RAID-1 device consisting of two block volumes and one spare device?

A. mdadm -create /dev/md0 -level=1 -raid-devices=2 /dev/xvdd1 /dev/xvdd2 -spare-devices=1 /dev
/xvdd3
B. mdadm -create /dev/md0 -level=5 -raid-devices=2 /dev/xvdd1 /dev/xvdd2 -spare-devices=1 /dev
/xvdd3
C. mdadm -create /dev/md0 -level=0 -raid-devices=2 /dev/xvdd1 /dev/xvdd2 -spare-devices=1 /dev
/xvdd3
D. mdadm -create /dev/md0 -level=1 -raid-devices=2 /dev/xvdd1 /dev/xvdd2

Answer: A

Explanation:
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:
* OracleLinux 8 Managing Storage Devices - RAID Configuration
* OracleLinux 8 mdadm Manual
These references provide comprehensive details on RAID levels,mdadmcommand syntax, and options for creating and managing RAID arrays in Oracle Linux.

NEW QUESTION # 19
Which two commands relabel an SELinux system after a reboot?

A. fixfiles -F onboot
B. touch /.autorelabel
C. Set kernel parameter autorelabel=0
D. fixfiles -F relabel
E. echo "relabel=1" > /.selinux
F. Set kernel parameter selinux=0

Answer: A,B

Explanation:
* Option D (Correct):Creating an empty file named.autorelabelin the root directory tells SELinux to relabel the entire file system during the next reboot.
* Option F (Correct):Thefixfiles -F onbootcommand schedules a full file system relabel on the next reboot.
* Option A, B, C, E (Incorrect):These options do not correctly set the system to relabel on reboot.
Oracle Linux Reference:Refer to:
* OracleLinux 8: SELinux Guide

NEW QUESTION # 21
Examine this command:
$ podman run -name=oracleshell -it oraclelinux:8 -slim
Which two statements are true upon execution?

A. The container creates and starts an interactive shell.
B. The container is removed by typing exit at the bash shell prompt.
C. The command fails if the oraclelinux:8 -slim image does not exist on the local machine.
D. The container is created and started in a single command.
E. The container named oracleshell must already exist; otherwise, the command fails.

Answer: A,D

Explanation:
Understanding the Command:
$ podman run --name=oracleshell -it oraclelinux:8-slim
(Note: The image is likely oraclelinux:8-slim without a space.)
* podman run:Creates and starts a new container.
* --name=oracleshell:Assigns the name oracleshell to the container.
* -it:Runs the container in interactive mode with a pseudo-TTY.
* oraclelinux:8-slim:Specifies the image to use.
Option A: The container creates and starts an interactive shell.
* Explanation:
* The -it option runs the container interactively.
* If no command is specified, it executes the default command in the image (usually /bin/bash).
* This provides an interactive shell inside the container.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Running Containers Interactively:
"You can run a container in interactive mode using the -i and -t options together." Option D: The container is created and started in a single command.
* Explanation:
* The podman run command handles both creation and starting of the container.
* There's no need to create the container separately.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Creating and Running Containers:
"The podman run command creates and starts a container in one operation." Why Other Options Are Incorrect:
Option B:The container does not need to pre-exist; podman run creates it if it doesn't exist.
Option C:If the image doesn't exist locally, podman will attempt to pull it from the registry.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Pulling Images:
"If you attempt to run a container with an image that does not exist locally, Podman automatically pulls the image from a registry." Option E:The container is not removed upon exit unless the --rm option is used.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Automatically Removing Containers:
"Use the --rm option to automatically remove the container when it exits." Conclusion:
* Correct Options:A, D
* Summary:The command creates and starts a new container named oracleshell and opens an interactive shell session inside it.
