Which file system is a FAT32 file system for Linux?

VFAT

Marco recently made some partition changes, and the kernel is not recognizing the partitions. Which of the following commands should Marco use to resolve the problem? cat /etc/partitions df fdisk -l partprobe

partprobe The partprobe command makes a request to the operating system to re-read the partition table. The operating system kernel reads the partition table and recognizes the table changes. cat /etc/partitions displays the currently recognized partitions, but does not perform an update.df displays partition information.fdisk -l displays partition information.

You created a swap area on sda3, but it is not activated. What command will activate this swap partition?

swapon /dev/sda3 Use swapon /dev/sda3 to activate the swap partition. Use swapon -a to activate all swap partitions listed in /etc/fstab. (A swap partition is the location on the hard drive where an operating system writes memory information when it runs out of RAM.)

Which of the following directories is specified by Filesystem Hierarchy Standard (FHS) as a mount point for removable media, such as USB storage media, DVDs, CD-ROMs, and Zip disks? /mnt / /media /mount

/media /media is specified by Filesystem Hierarchy Standard (FHS) as a mount point for removable media, such as USB storage media, DVDs, CD-ROMs, and Zip disks. /mnt is often used for temporarily mounted filesystems. / represents the root directory of the Linux system and is not recommended as a mount point for removable media. /mount is not specified in the Filesystem Hierarchy Standard (FHS).

Which of the following is the maximum number of primary partitions that can be created on a single hard disk drive? 8 4 2 Unlimited

4 There can be a maximum of four primary partitions on a single hard disk drive. A partition is a logical division of a storage device associated with a hard disk drive. A primary partition is one that is used to store an operating system. Primary partitions: Can hold operating system boot files. Cannot be further subdivided into logical drives. Can be formatted.

You suspect your /dev/sda3 partition is in need of repair. Which of the following fsck options will repair the errors without any interaction from you? -t -s -r -a

-a Use fsck -a to automatically repair the /dev/sda partition without any interaction from you (no questions appear). Other fsck options include the following: -s serializes fsck when multiple file systems are checked. -t specifies the type(s) of file system to be checked. -r prompts for confirmation when errors are found and ask permission to fix the errors (only when -a is not specified).

You are inspecting the superblocks and block information on your file system. You need dumpe2fs to display only the blocks that are reserved as bad in the file system. Which of the following options should you use? -x -f -h -b

-b Use dumpe2fs -b to print the blocks that are reserved as bad in the file system. dumpe2fs prints superblock and block information for an ext2, ext3, or ext4 file system. This includes information for each sector on the partition about sector type, block ranges, inode information, free blocks, and similar information. Other dump32fs command options include the following: -h prints only super block information. -f forces dumpe2fs to display a file system even though it may have some file system feature flags the system may not understand. -x prints group information block numbers in hexadecimal format.

Your ext3 file system has experienced a significant amount of corruption. To examine the file system, you want to use the debugfs utility. Which of the following debugfs options should you use to examine the file system? -c -w -Z -f

-c Use debugfs -c to specify the file system should open in catastrophic mode. debugfs is useful for file systems with significant corruption. debugfs examines and changes the state of an ext2, ext3, or ext4 filesystem. It allows administrators to unlink directories, change inode blocks, find all inodes that point to a block, and several other similar functions. Other debugfs command options include the following: -w specifies the filesystem should open in read-write mode. -f executes commands in a text file. -Z prints the version number of debugfs and exits.

You need to configure your Linux system to allow only the root user account to mount the CD-ROM device. Which of the following options should you add to the /etc/fstab file? /dev/cdrom /media/cdrom -t iso9660 ro,nouser,noauto /dev/cdrom /media/cdrom -t iso9660 ro,user,noauto /dev/cdrom /media/cdrom -t iso9660 ro,users,noauto /dev/cdrom /media/cdrom -t iso9660 ro

/dev/cdrom /media/cdrom -t iso9660 ro,nouser,noauto Use /dev/cdrom /media/cdrom -t iso9660 ro,nouser,noauto to allow only the root user account to mount the CD-ROM device. -t iso9660 specifies the type as filesystem structure used on CD-ROMs. Be aware of the following mount options: nouser allows only the root user to mount the volume. noauto prevents the volume from being mounted automatically. Use this option for removable media. ro mounts the volume read only. user identifies a specific user who can mount the volume. users allows any user to mount the volume. rw mounts the volume read/write. suid allows the SUID bit to be set on files in the volume. (nosuid disables this function.) defaults uses the following default settings: rw, suid, dev, exec, auto, nouser, and async.

Type the full device file name for the second partition on the hard drive with the lowest ID number.

/dev/sda2 /dev/sda2 is the second partition (2) on the hard drive with the lowest ID number (a). /dev/sdxn file names identify hard drives. A letter follows the sd designation and identifies the ID of the hard drive. At the end of the name, a number identifies the partition on the drive.

Type the full device file name for the first partition on the hard drive with the third lowest ID number.

/dev/sdc1 /dev/sdc1 is the first partition (1) on the hard drive with the third lowest ID number (c). /dev/dsxn file names identify hard drives and partitions. A letter follows the sd designation and identifies the ID of the hard drive. At the end of the name, a number identifies the partition on the drive.

You want to mount a number of file systems each time the system is brought up. Which configuration file should hold the configuration information for the file systems to be mounted? /etc/inittab /etc/profile /etc/fstab /etc/mount

/etc/fstab /etc/fstab holds the file system table configuration of all filesystems to be mounted during normal operations. /etc/profile stores system-wide configuration commands and is used primarily to set environment variables. /etc/inittab determines the default runlevel for the system and starts the appropriate daemons for that runlevel. /etc/mount is not defined to show mounted file systems.

What is the full path and filename of the file that contains the file system table for a Linux system?

/etc/fstab The Linux file system table (fstab) is file located at /etc/fstab. The /etc/fstab file identifies volumes to mount each time the system boots. When the system boots, it automatically mounts the volumes identified in the file.

You have added several new hard disks to your system. After partitioning and formatting, you have modified a configuration file to mount these new file systems automatically. You want to document the change you made. Which of the following configuration files would you document? /etc/inittab /etc/crontab /etc/fstab /etc/modules.conf

/etc/fstab You want to document the changes you made in /etc/fstab. /etc/inittab defines the initial processes on boot-up. /etc/modules.conf defines kernel loadable modules. /etc/crontab defines jobs that run at particular dates and times.

Which file shows the currently mounted volumes? /etc/mount.conf /etc/mount /etc/mtab /etc/fstab

/etc/mtab The /etc/mtab file shows the currently mounted volumes. /etc/fstab controls which volumes are mounted at boot. /etc/mount and /etc/mount.conf are not defined by FHS to show mounted filesystems.

Which of the following hexadecimal codes represents an extended partition? 0x85 0x88 0x83 0x82

0x85 0x82 represents a Linux swap partition. 0x83 represents a Linux partition. 0x88 represents a Linux logical partition.

Which of the following is the maximum number of GUID partitions that can be created using the gdisk utility? 8 128 32 64

128 If you use gdsik to manage GUID partitions on a Linux system, you can create up to 128 partitions on each hard disk.

Gloria, a Linux administrator, used the gdisk utility to create eight partitions on a new hard drive. Which of the following BEST describes the partitions Gloria has created? All eight partitions are logical partitions. There are no primary or extended partitions. The first three partitions are primary partitions. The fourth is an extended partition that holds five logical partitions, making eight partitions in total. The first seven partitions are primary partitions. The eighth partition is an extended partition that can be used to contain logical partitions. All eight partitions are the same. They are simply partitions. There are no primary, extended, or logical partitions.

All eight partitions are the same. They are simply partitions. There are no primary, extended, or logical partitions. Since there are eight partition and gdisk was used, Gloria must be using GPT. Therefore, all partitions are the same. They are just partitions. GUID partitioning does not use the concept of primary, extended, or logical partitions. Primary, extended, and logical partitions are part of MBR partitioning.

Tom, a Linux administrator, has installed a new hard disk. He creates two primary partitions, sdb1 and sdb2, and one extended partition, sdb3. He formats sdb1 with ext3 and sdb2 as a swap area. When Tom attempts to format sdb3 as a swap area, he is unable. Which of the following explains why Tom can't format sdb3? A single drive can only have one swap area. A swap area can only reside on the second primary partition. Only a primary partition can be formatted as a swap area. An extended partition can't be formatted.

An extended partition can't be formatted. An extended partition can't be formatted. A swap area can be located on any partition. A swap area can be located on a primary partition or a logical partition within the extended partition. A single drive can have multiple swap areas.

You are asked to help a user who is complaining that file system errors are being reported during boot-up. When you reboot the user's system, you see errors on sda2. Which of the following strategies will check the file system on sda2 and automatically fix the errors without asking any questions? Change to single user mode and run fsck -a /dev/sda2. Run chkdsk /dev/sda2. Run fsck /dev/sda2. Change to single user mode and run fdisk /dev/sda2. Change to single user mode and run scandsk /dev/sda2.

Change to single user mode and run fsck -a /dev/sda2. You want to change to single user mode to prevent any access to the file system and use the fsck utility with the -a option on /dev/sda2 to automatically repair the file system without asking any questions. It is also important to ensure the volume on which you are using fsck is not mounted. Using fsck in mounted volumes can corrupt most filesystems. There are no disk utilities called scandsk or chkdsk in Linux. fdisk is used for partitioning a drive, not for repairing a file system.

Which of the following describes the effects of the tune2fs -j /dev/sdb1 command? Displays the superblock on the /dev/sdb1 device. Changes how many times the /dev/sdb1 device is mounted before running fsck. Remounts the /dev/sdb1 device as read-only. Converts the /dev/sdb1 device to ext3.

Converts the /dev/sdb1 device to ext3. tune2fs -j /dev/sdb1 converts the /dev/sdb1 device file system from ext2 to ext3 without affecting the data on the drive. Use tune2fs to adjust tunable file system parameters on ext2, ext3, and ext4 file systems. Other tune2fs options include the following: -c adjusts the number of mounts after which the file system will be checked. -e remount-ro remounts the file system as read-only. -l lists the contents of the file system super block. -o acl enables Posix access control lists.

Yesterday, you created a new swap area for your system. Today, after rebooting the system, you find that the swap area is not mounted. What should you do to ensure that the swap area is mounted each time the system boots? Edit /etc/mtab and add the swap partition. Edit /etc/inittab and add the swap area. Edit /etc/fstab and add the swap partition. Run the mount --auto command and identify the swap area partition. Remount the swap area. Then run export mount to make the change persistent.

Edit /etc/fstab and add the swap partition. To mount the swap area each time the system boots, edit the /etc/fstab file and add the swap area with the auto keyword. /etc/mtab shows currently mounted volumes. /etc/inittab determines the default runlevel for the system and starts the appropriate daemons for that runlevel.

You attempt to unmount a volume using the umount /dev/sdd3 command, but you receive a device is busy error message. Which of the following strategies will be MOST likely to allow you to unmount the file system? (Select TWO). Use the fscls command to close any open files on the filesystem. Try to unmount again. Find and close any open files on the file system, and try to unmount again. Perform a backup of the sdd3 device and try to unmount again. Edit /etc/fstab and remove the mount. Try unmount again. Make sure your current working directory is not on the file system and try to unmount again.

Find and close any open files on the file system, and try to unmount again. Make sure your current working directory is not on the file system and try to unmount again. Some file systems will not allow you to unmount a file system if your current working directory is in that file system. The command lsof lists open files, and the pid that has the files open. This will allow you to close the file, or at least kill the process that has the file open. There is no command called fscls. Editing /etc/fstab will not help to unmount a filesystem during the current session. A backup will not close a file that is open.

Which of the following is true for an extended partitions? The ext3 extended file system does not support journaling. You cannot create logical partitions inside an extended partition. You cannot format an extended partition. The ext2 extended file system supports Linux users and groups, but not permissions.

You cannot format an extended partition. You cannot format an extended partition. However, you can create logical partitions inside an extended partition and format them. The Third Extended File System (ext3) is an updated version of ext2 that supports journaling. The Second Extended File System (ext2) supports Linux users, groups, and permissions.

You are requested to help a user who reports that he has no more local storage space. You go to his system and log in as the root user. Which of the following commands will display the available disk space on all partitions? (Select TWO). du -a du -h fdisk -free df dskuse -free df -h

df -h df df shows the size, used blocks, and available blocks for each partition. Using df -h shows the same information in bytes instead of blocks. du is used to show the disk usage of each file in a directory in blocks; du -a is for all files, and du -h shows the usage in bytes, not blocks. Fdisk is used for partitioning a drive. There is no dskuse command.

When creating an ext2 or ext3 file system, a fixed number of inodes is assigned. Which of the following commands shows the number of inodes, number of free inodes, and number of used inodes? ls -i df -i du --inodes mke2fs -i

df -i df -i or df --inode displays the total number of inodes, used inodes, and free inodes; the percentage of inodes in use; and the mount point. du --inodes lists inode usage information instead of block usage. There is no -I option available. ls -i or ls --inode displays the index number of each file or directory. mke2fs -i is used to specify the bytes per inode ration to be used during the file system creation process.

You have created a separate partition for the sales team and mounted it to the /sales directory. The team is about to begin a new project, and they want to make sure there is enough disk space to hold upcoming files. Which of the following commands will show you the amount of free space? diff /sales part /sales free /sales df /sales

df /sales Use the df /sales command to view the free space on the partition. Use the free command to show memory statistics. Use the diff command to compare two files.

What command would you enter at the command prompt to list all files and directories in the badams home directory along with a file size and a total amount of space taken up by the directory?

du -c /home/badams Use du /home/badams to lists all files and directories in the badams home directory along with a file size and a total amount of space taken up by the directory. The du command displays files and file sizes in and below a specified directory. Common du options include the following: -c lists a total amount of space used in the directory. -h displays the output in human readable format (bytes, KB, MB, GB). -s lists only the total, not each file. -a evaluates all files, not just directories.

Which of the following commands allows you to use a backup superblock when the primary superblock has been corrupted? e2fsck -f -b 16385 /dev/sda1 mke2fs -n /dev/sda1 mkfs -t ext2 /dev/sda1 fsck /dev/sd1

e2fsck -f -b 16385 /dev/sda1 Use the e2fsck -f -b 16385 /dev/sda1 command to use the backup superblock at block 16385. The mke2fs -n /dev/sda1 command tells you the locations of the superblocks on the disk. The fsck /dev/sd1 command starts the fsck utility on the device. The mkfs -t ext2 /dev/sda1 command formats the sda1 partition.

Which of the following is the MOST common Linux file system? XFS JFS ReiserFS ext4

ext4 Ext4 is the most common Linux file system. XFS, JFS and ReiserFS are newer and less popular Linux file systems.

The system requirements for a new Linux computer show that the system will primarily be used to store documents of small size. Which of the following file systems would be the MOST efficient at storing these documents on a Linux system? ext3 ext2 ext4 HPFS

ext4 The Ext4 file system is more efficient at storing small files than most file systems. Ext2 and Ext3 store small files less efficiently than Ext4. HPFS is more efficient for storing files than most files systems, but HPFS is not a Linux file system.

Which of the following Linux file systems support journaling? VFAT ext2 ext4 swap

ext4 The ext4 file systems support journaling. Journaling is a method used to help ensure data and file system integrity and minimize boot times after system crashes. The ext2 file system does not support journaling. VFAT is a FAT32 file system for Linux and does not support journaling. The swap file system is a pseudo file system and is used as virtual memory.

Which of the following commands/command sequences can be used to view the partition information on the first hard disk? (Select TWO.) fdisk /dev/sd1, then press p cat /proc/part cat /etc/part fdisk -l fdisk /dev/sda, then press p

fdisk /dev/sda, then press p fdisk -l Both the fdisk -l command and the fdisk /dev/sda command followed p can be used to view partition information for the first hard disk. The /proc/partitions file also holds partition information, but is difficult to read. The cat /proc/part command will most likely return "No such file or directory" since the /etc/part file does not likely exist. The cat /etc/part command will most likely return "No such file or directory" since the /etc/part file does not likely exist. The fdisk /dev/sd1 command will return "No such file or directory" since the /dev/sd1 file does not exist. (The first disk is sda, not sd1.)

Which of the following commands partitions the second hard disk on a Linux system? fdisk /dev/sdc fdisk /sd0-1 fdisk /dev/sdb format /dev/sdb1

fdisk /dev/sdb The fdisk /dev/sdb command can be used to open the fdisk utility to partition the second hard disk. The fdisk /sd0-1 command will return "No such file or directory" since the /sd0-1 device file does not exist. The format /dev/sdb1 command will format the first partition on the second disk. It will not partition the second hard disk. The fdisk /dev/sdc command can be used to open the fdisk utility to partition the third hard disk, but not the second hard disk.

Which partition management utility can be used to define and change various different GUID partition configurations without committing the configuration to the disk until the w command is used? lsblk parted fdisk gdisk

gdisk The gdisk utility allows you to define and change various different GUID partition configurations. The configurations are only saved in memory until you are ready to commit them to disk. The fdisk utility allows you to do the same thing, but only with MBR partitions. The parted utility writes the configuration to disk immediately as you define it. The lsblk utility is used to list block devices.

You have installed a new blank hard drive on you Linux system. This is the second drive on the system, so it is represented in the file system by the /dev/sdb file. You need to create GUID partitions on this drive. What command do you use to start the GUID disk management utility to create partitions on the /dev/sdb drive?

gdisk /dev/sdb The GUID disk management utility is called gdisk. It works very much like the fdisk utility that is used to manage MBR partitions. To start up the gdisk utility to create partitions on the /dev/sdb drive, you enter gdisk /dev/sdb.

Anna is attempting to unmount the mount point /mnt/data. The umount command failed and displayed error message stating that the device is busy. Anna suspects there my be an open file causing the issue. Which of the following commands will show Anna a list of open files? stat uname lsof awk

lsof lsof displays open files in the file system. lsof displays the following information by default: The command used to access the file Process ID Name of the user accessing the file A file descriptor File node type Device numbers File size Inode address File path awk is an interpreter for the AWK text processing language. stat displays the status of a file or process. You would first need to know the name of the file or process. uname shows information about the system.

Which of the following commands formats the second partition on the fourth disk drive with the ext3 file system? format -e3 sdb2 mke2fs -e3 /dev/sdd2 fdisk -e3 /dev/sdb2 mke2fs -j /dev/sdd2

mke2fs -j /dev/sdd2 Use the mke2fs -j /dev/sdd2 to make an ext3 filesystem. You could also use the mkfs -t ext3 /dev/sdd2 command. format is not a standard Linux command. fdisk is used for partitioning a drive, not for creating a filesystem. mke2fs -e3 /dev/sdd2 will return an error because there is no -e3 option.

You need to create an ext4 file system on the first partition on the second hard disk drive. What command should you enter at the command prompt?

mkfs -t ext4 /dev/sdb1 Use one of the following commands to format the first partition on the second drive: mkfs.ext4 /dev/sdb1 mke2fs -t ext4 /dev/sdb1 mkfs -t ext4 /dev/sdb1 The Ext4 file system is the latest version in the ext file system family. Ext4 can handle files up to 16 terabytes and disk sizes up to 1 exabyte.

One of the Linux servers for the accounting department needs additional memory to fix recent performance issues. You have ordered the memory, but it is backordered, so you decide to add a swap partition to the server to help the performance issues immediately. Which of the following commands will add a swap partition to the first partition on the third hard drive? fdisk swapon /dev/sdc1 mkswap /dev/sdc1 vmstat

mkswap /dev/sdc1 mkswap creates a swap partition that is used to write information when an operating system runs out of RAM. fdisk is used to create standard partitions. swapon is used to active a swap partition. vmstat provides virtual memory statistics and is used to monitor, collect, and display OS memory, processes, and the like.

A user is trying to access a file system mounted at /mnt/sdb1, but receives an error that states No such file or directory. Which commands can you use to see the current mount points? (Select TWO). mntfs df mount mntchk fsck mounts

mount df Use the mount command with no arguments to show all the current mount points. df will also show which file systems are mounted to what points. The command fsck is used to check file systems but does not show the mount points. There are no commands called mounts, mntchk, or mntfs.

A number of new file systems have been added to the server and you want them to be active now. You also do not want to bring the server down. Which command makes the changes active? init q mount -r mount -t mount -a

mount -a The command mount -a forces a re-read of the entries in the /etc/fstab file and makes the settings active.

You need to mount the CD-ROM device to the /media/cdrom directory. What command should you enter at the command prompt?

mount /dev/cdrom /media/cdrom Use mount /dev/cdrom /media/cdrom to mount the CD-ROM device to the /media/cdrom mount point. The /dev/cdrom device file name is just a symbolic link to the actual device (sr0), so mount /dev/sr0 /media/cdrom will also work.

You have partitioned and formatted a new hard drive, sdc. You want to mount the first partition on sdc to directory /mnt/newdisk. Which command will perform the mount correctly? mount /mnt/newdisk /dev/sdc1 mount /dsk/sdc_first /mnt/newdisk mount /sdc1 /mnt/newdisk mount /dev/sdc /mnt/newdisk mount /dev/sdc1 /mnt/newdisk

mount /dev/sdc1 /mnt/newdisk When mounting a device and partition, you specify the /dev directory and the device and partition you want to mount and then the mount point to mount the device to. The correct format for mount is mount item and mount point. Devices are always in the /dev directory. There is no /dsk directory. Partitions on hard drives are numbered.

What is the name of the partition management utility that will both create GUID partitions and create file systems on those partitions?

parted The parted utility is a partition editor that allows you to create GUID partitions and then create file systems on those partitions. You can use gdisk to create partitions, but you cannot use it to create file systems.

You have a Linux system with two activated swap partitions, sda3 and sdb2. Which of the following commands can you use to deactivate only the sda3 swap partition? fdisk d /dev/sda3 pvcreate /dev/sda3 swapoff -a swapoff /dev/sda3

swapoff /dev/sda3 The swapoff /dev/sda3 command will deactivate the sda3 swap partition. The swapoff -a command will deactivate all swap partitions listed in /etc/fstab. The pvcreate command is used to create LVM physical volumes. The fdisk command creates and displays partitions; however, fdisk d /dev/sda3 is the incorrect syntax for the fdisk utility.

You need to convert the file system of /dev/sdb3 from ext2 to ext3 without affecting the data on the drive. What command and option should you enter at the command prompt?

tune2fs -j /dev/sdb3 Use tune2fs -j /dev/sdb3 to convert the file system from ext2 to ext3 without affecting the data on the drive. Use tune2fs to adjust tunable file system parameters on ext2, ext3, and ext4 file systems. Other tune2fs options include the following: -c adjust the number of mounts after which the file system will be checked. -e remount-ro remounts the file system as read-only. -l lists the contents of the file system super block. -o acl enables Posix access control lists.

Partition /dev/sdb2 is mounted to /mnt/temp. You need to unmount /dev/sdb2. Which commands would you use? (Select TWO). (Each option is a complete solution.) umount /dev/sdb2 umount /mnt/temp dismount /mnt/temp dismount /dev/sdb2 unmount /dev/sdb2

umount /dev/sdb2 umount /mnt/temp Use umount to unmount a device. You can specify the device, /dev/sdb2, or the mount point, /mnt/temp. There are no utilities called unmount or dismount in Linux.

You have an xfs file system in your Linux computer. You need to display the XFS file system parameters, such as the block size and inode data structures. Which of the following commands should you use? (Select TWO). (Each answer is an independent solution.) xfs_metadump mkfs.xfs xfs_growfs -n xfs_info

xfs_info xfs_growfs -n xfs_growfs -n and xfs_info display the XFS file system parameters, such as the block size and inode data structures. The XFS file system is proficient at handling large files and offers smooth data transfers. It also can reside on a regular disk partition or on a logical volume. xfs_metadump copies (dumps) the metadata from an XFS file system to a file. mkfs.xfs creates an XFS file system.

You have an XFS file system in your Linux system represented by /dev/sdb1. You need to copy all the filenames on the drive to the /reviewxfs file. You must be able to read the filenames in the /reviewxfs file. Which of the following commands should you use? xfs_metadump -a /dev/sdb1 /reviewxfs xfs_metadump -o /dev/sdb1 /reviewxfs xfs_metadump -e /dev/sdb1 /reviewxfs xfs_metadump -g /dev/sdb1 /reviewxfs

xfs_metadump -o /dev/sdb1 /reviewxfs Use xfs_metadump -o /dev/sdb1 /reviewxfs to copy (dump) the metadata from the XFS file system on /dev/sdb1 to the /reviewxfs file. By default, the file names and extended attribute names are obfuscated before they are dumped. -o disables obfuscation of file names and extended attributes. xfs_metadump -e stops dumping the file system if there is a read error, -g shows the dump progress, and -a copies all metadata blocks. However, none of these options disables obfuscation of file names and extended attributes.

What is the file path and name of the directory that contains device files for hard drives, optical drives, and USB devices?

/dev The /dev directory contains device files for hard drives, optical drives, and USB devices. The /dev directory contains files for all types of devices, even those that do not exist on the system.

You are preparing to mount a device local to your system. Which directory holds the device files? /dev /local/dev /devices /opt/dev

/dev The files for devices are always stored in /dev according to the FHS. The FHS does not define the directories /local/dev, /opt/dev or /devices for storing device files.

Which of the following is the maximum number logical partitions allowed on an extended partition? 2 Unlimited 1 4

Unlimited Extended partitions can be subdivided into an unlimited amount of logical drives. There can be only be one extended partition on a single hard disk drive.
