Which of the following commands is used on a Linux system to delete all the files and directories in a Linux system’s filesystem?

A. rm -rf .
B. rm -rf /
C. rm .
D. rm /

A

B. rm -rf /

The rm command is a command-line utility for removing files or directories. The “rm -rf /” is the most dangerous command to issue in Linux. The rm -rf command is one of the fastest ways to delete a folder and its contents. But a little typo or ignorance may result in unrecoverable system damage. The -r option means that the command will recursively delete the folder and its subfolders. The -f option means that even read-only files will be removed without asking the user. The use of / indicates that the remove command should begin at the root directory (/) and recursively force all files and folders to be deleted under the root. This would delete everything on the system. The . would only begin deleting from the current working directory and then delete all files and folders further down the directory structure, not the entire file system.

Q

An administrator arrives at work and is told that network users are unable to access the shared drive on a Windows server. The administrator logs into the server and sees that some Windows Updates were automatically installed last night successfully, but now the network connection shows “limited” with no availability. What rollback action should the technician perform?

A. Antivirus updates
B. Web browser
C. Server’s IP address
D. Server’s NIC address

A

D. Server’s NIC address

When automatically receiving updates through the Windows Update service, your server can receive driver updates for its network interface card (NIC), graphics cards, and other peripherals. This can accidentally install an incompatible driver that causes network connectivity issues to occur. A best practice is to always set driver updates to “manual” so that you can download and test them in a lab before upgrading your production servers. If your drivers were updated and this is causing the connectivity issue, you can perform a driver rollback to the last known working version of the drivers. An IP address is bound to a network interface card using DHCP and there is no such thing as a “rollback” for a server’s IP address. The error of “limited” connectivity is associated with the network interface card and the network connection, not the antivirus or the web browser.

Q

You want to ensure that only one person can enter or leave the server room at a time. Which of the following physical security devices would BEST help you meet this requirement?

A. Access control vestibule
B. Cipher lock
C. Thumbprint reader
D. Video monitoring

A

A. Access control vestibule

An access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens. Video monitoring is a passive security feature, so it won’t prevent two people from entering at once. The thumbprint reader or cipher lock will ensure that only an authorized user can open the door, but it won’t prevent someone from piggybacking and entering with them.

Q

You attempt to boot a Windows 10 laptop and receive an “Operating System Not Found” error on the screen. You can see the hard disk listed in the UEFI/BIOS of the system. Which of the following commands should you use to repair the first 512-byte sector on the hard disk?

A. bootrec /rebuildbcd
B. bootrec /fixboot
C. diskpart list
D. bootrec /fixmbr

A

D. bootrec /fixmbr

The master boot record (MBR) is the first 512-byte sector on a hard disk. It contains the partitioning information for a drive. To repair the master boot record (MBR), you should use the command “bootrec /fixmbr” 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 /fixboot” command is used to attempt a repair of the boot sector of a drive. The “bootrec /rebuildbcd” command is used to add missing Windows installations to the Boot Configuration Database (BCD). The diskpart command is a command-line disk-partitioning utility available for Windows that is used to view, create, delete, and modify a computer’s disk partitions

Q

Which of the following macOS features is used to backup and restore files to an external hard disk?

A. Snapshot
B. Time Machine
C. Remote disc
D. Boot Camp

A

B. Time Machine

Time Machine is the built-in backup feature of the macOS operating system. The Time Machine utility enables data to be backed up to an external drive. By default, Time Machine keeps hourly backups for the past 24 hours, daily backups for a month, and weekly backups for all previous months. When the drive used to store backups becomes full, Time Machine removes older backups to free up space. Time Machine automatically backs up all of the system’s files, including apps, music, photos, email, documents, and system files. Once a user has a valid backup in Time Machine, they can restore files from the backup if the original files are ever corrupted or deleted on their Mac or if the hard disk (or SSD) is erased or replaced. Remote disc is a feature in macOS that enables a user to access a CD/DVD on another Mac or Windows computer. This was created because Apple’s Mac computers have not been sold with an internal optical drive since 2016. Boot Camp is used to allow dual booting on a Macintosh computer. It allows the user to boot into either macOS (OS X) or Windows as the computer is rebooted. Boot Camp is only supported on Intel-based macOS systems, though. A snapshot is used to backup virtual machines by creating a state of the disk at a particular point in time. Snapshots allow a technician to roll back any changes made to a VM during a session if needed.

Q

Which of the following commands is used on a Linux system to list the currently running processes on a system?

A. grep
B. ps
C. ls
D. kill

A

B. ps

The ps command is used to list the currently running processes, and their PIDs and some other information depend on different options. It reads the process information from the virtual files in the /proc file system. The /proc directory contains virtual files and is known as a virtual file system. The kill command sends a signal to specified processes or process groups, causing them to act according to the signal. When the signal is not specified, it defaults to -15 (-TERM), which terminates the specified process by gracefully stopping it. If “kill -9” is used instead, it will immediately kill the process. The grep is a command-line utility for searching plain-text data sets for lines that match a regular expression. The grep command works on Unix, Linux, and macOS operating systems. Grep is an acronym that stands for Global Regular Expression Print. The ls command lists the files or directories in the current path of a Unix, Linux, or Mac operating system. When invoked without any arguments, ls lists the files in the current working directory.

75
Q

An attacker uses the nslookup interactive mode to locate information on a Domain Name Service (DNS). What command should they type to request the appropriate records for only the name servers?

A. request type=ns
B. locate type=ns
C. transfer type=ns
D. set type=ns

A

D. set type=ns

The nslookup command is used to query the Domain Name System to obtain the mapping between a domain name and an IP address or to view other DNS records. The “set type=ns” tells nslookup only reports information on name servers. If you used “set type=mx” instead, you would receive information only about mail exchange servers.

What umask should be set for a directory to have 700 as its octal permissions?

A. rwxrwxrwx
B. r–r–r–
C. rwx——
D. rwx—rwx

A

C. rwx——

RWX is 7 and — is 0. In Linux, you can convert letter permissions to octal by giving 4 for each R, 2 for each W, and 1 for each X. R is for read-only, W is for write, and X is for execute. The permissions strings are written to represent the owner’s permissions, the group’s permissions, and the other user’s permissions.
