NEW QUESTION # 325
A systems administrator requires that all files that are created by the user named web have read-only permissions by the owner. Which of the following commands will satisfy this requirement?
- A. chown web:web /home/web
- B. chmod -R 400 /home/web
- C. setfacl read /home/web
- D. echo "umask 377" >> /home/web/.bashrc
Answer: D
Explanation:
The command that will satisfy the requirement of having all files that are created by the user named web have read-only permissions by the owner is echo "umask 377" >> /home/web/.bashrc. This command will append the umask 377 command to the end of the .bashrc file in the web user's home directory. The .bashrc file is a shell script that is executed whenever a new interactive shell session is started by the user. The umask command sets the file mode creation mask, which determines the default permissions for newly created files or directories by subtracting from the maximum permissions (666 for files and 777 for directories). The umask 377 command means that the user does not want to give any permissions to the group or others (3 = 000 in binary), and only wants to give read permission to the owner (7 - 3 = 4 = 100 in binary). Therefore, any new file created by the web user will have read-only permission by the owner (400) and no permission for anyone else.

NEW QUESTION # 326
A Linux engineer is setting the sticky bit on a directory called devops with 755 file permission.
Which of the following commands will accomplish this task?
- A. chown 1755 devops
- B. chmod 1755 devops
- C. chmod -s 755 devops
- D. chown -s 755 devops
Answer: B
Explanation:
The command that will set the sticky bit on a directory called devops with 755 file permission is chmod 1755 devops. This command will use chmod to change the mode of the directory devops to 1755, which means that the owner has read, write, and execute permissions (7), the group has read and execute permissions (5), and others have read and execute permissions (5). The first digit 1 indicates that the sticky bit is set on the directory, which is a special permission that prevents users from deleting or renaming files in the directory that they do not own.
NEW QUESTION # 327
A Linux administrator recently changed the IP addresses of all the web servers from 10.10.50.x to
10.10.100.x. The administrator needs to update the serverlist.txt file to reflect the change.
The file contains the following:
10:WebSvr01:10.10.50.21:Main
11:WebSvr02:10.10.50.22:Acconting
12:WebSvr03:10.10.50.23:Intranet
20:NFS01:10.10.20.21:FileServer
30:SMTP01:10.10.30.31:Email
Which of the following commands will change the IP addresses and update the files in place?
- A. sed -g 's|.50|.100|a' serverlist.txt
- B. sed 's|.50|.100|g' serverlist.txt
- C. sed -i 's|.50|.100|' serverlist.txt

NEW QUESTION # 329
Joe, a user, is unable to log in to the Linux system Given the following output:
Which of the following command would resolve the issue?
- A. pam_tally2 -u joe -r
- B. chage -E 90 joe
- C. passwd -u joe
- D. usermod -s /bin/bash joe
Answer: A
Explanation:
Explanation
Based on the output of the image sent by the user, Joe is unable to log in to the Linux system because his account has been locked due to too many failed login attempts. The pam_tally2 -u joe -r command will resolve this issue by resetting Joe's failed login counter to zero and unlocking his account. This command uses the pam_tally2 module to manage user account locking based on login failures. The usermod -s /bin/bash joe command will change Joe's login shell to /bin/bash, but this will not unlock his account. The passwd -u joe command will unlock Joe's password if it has been locked by passwd -l joe, but this will not reset his failed login counter or unlock his account if it has been locked by pam_tally2. The chage -E 90 joe command will set Joe's account expiration date to 90 days from today, but this will not unlock his account or reset his failed login counter.

- A. top -u 'Joe'
- B. ps -ax 'Joe'
- C. jobs -n 'Joe'
- D. lsof -p 'Joe'
Answer: A

top -u Joe filters the process display to only show processes owned by user Joe, allowing the administrator to see if Joe is running any unauthorized processes.
NEW QUESTION # 335
A user is unable to remotely log on to a server using the server name server1 and port 22. The Linux engineer troubleshoots the issue and gathers the following information:
Which of the following is most likely causing the issue?
- A. sshd is not an active service.
- B. sshd is running on a non-standard port.
- C. serverl is using an incorrect IP address.
- D. server 1 is not in the DNS.
Answer: B
Explanation:
The sshd is the Secure Shell Daemon, which is a service that allows remote login to a Linux system using the SSH protocol. The output shows that the sshd is running on port 2222, which is a non-standard port for SSH. The default port for SSH is 22, which is what the user is trying to use. Therefore, the statement B is most likely causing the issue. The statements A, C, and D are incorrect because they do not explain why the user cannot log on using port 22.

NEW QUESTION # 336
A systems engineer is adding a new 1GB XFS filesystem that should be temporarily mounted under /ops/app.
Which of the following is the correct list of commands to achieve this goal?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Explanation
The list of commands in option D is the correct way to achieve the goal. The commands are as follows:
fallocate -l 1G /ops/app.img creates a 1GB file named app.img under the /ops directory.
mkfs.xfs /ops/app.img formats the file as an XFS filesystem.
mount -o loop /ops/app.img /ops/app mounts the file as a loop device under the /ops/app directory. The other options are incorrect because they either use the wrong commands (dd or truncate instead of fallocate), the wrong options (-t or -f instead of -o), or the wrong order of arguments (/ops/app.img
/ops/app instead of /ops/app /ops/app.img). References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 10: Managing Storage, pages 323-324.

NEW QUESTION # 338
A Linux administrator needs to run a web application on a server that requires the use of a desktop web browser to enter the final configuration information. The administrator determines the server is running in multi-user mode. The administrator verifies that a web browser is installed on the server and that it has a display manager installed. Which of the following commands will best allow the administrator to temporarily use the web browser on the server?
- A. sudo systemctl restart gdm
- B. sudo systemctl set-default runlevel5.target
- C. sudo systemctl isolate graphical.target
- D. sudo systemctl --no-wall rescue
Answer: C
Explanation:
The systemctl isolate graphical.target command switches the system to graphical mode (runlevel 5). This will start the display manager and allow the administrator to use a graphical environment, including a web browser. The switch is temporary, and the system will revert to multi-user mode after reboot unless explicitly changed.
NEW QUESTION # 339
A Linux engineer is removing a previously created firewall rule. Which of the following commands will help the administrator accomplish this task?
- A. ufw delete 80/tcp deny
- B. delete7!
- C. ufw delete 80/tcp
- D. ufw delete deny 80/tcp
Answer: D
Explanation:
The ufw (Uncomplicated Firewall) delete command is used to remove rules.
If the original rule was ufw deny 80/tcp, it must be deleted with:ufw delete deny 80/tcp If the original rule was ufw deny 80/tcp, it must be deleted with:ufw delete deny 80/tcp If the original rule was ufw deny 80/tcp, it must be deleted with:ufw delete deny 80/tcp Why the other options are incorrect?
A: ufw delete 80/tcp # Incorrect, because delete requires specifying the action (allow or deny).
C: ufw delete 80/tcp deny # Incorrect syntax; deny must come before the port.
D: delete7! # Incorrect, this is not a valid ufw command.

NEW QUESTION # 341
A Linux administrator needs to create an image named sda.img from the sda disk and store it in the /tmp directory. Which of the following commands should be used to accomplish this task?
- A. dd of=/dev/sda if=/tmp/sda.img
- B. dd --if=/dev/sda --of=/tmp/sda.img
- C. dd if=/dev/sda of=/tmp/sda.img
- D. dd --of=/dev/sda --if=/tmp/sda.img
Answer: C
Explanation:
The command dd if=/dev/sda of=/tmp/sda.img should be used to create an image named sda.img from the sda disk and store it in the /tmp directory. The dd command is a tool for copying and converting data on Linux systems. The if option specifies the input file or device, in this case
/dev/sda, which is the disk device. The of option specifies the output file or device, in this case
/tmp/sda.img, which is the image file. The command dd if=/dev/sda of=/tmp/sda.img will copy the entire disk data from /dev/sda to /tmp/sda.img and create an image file.

NEW QUESTION # 343
A junior administrator updated the PostgreSQL service unit file per the data-base administrator's recommendation. The service has been restarted, but changes have not been applied. Which of the following should the administrator run for the changes to take effect?
- A. systemct1 enable postgresq1
- B. systemct1 daemon-reload
- C. Systemct1 get-default
- D. systemct1 mask postgresq1
Answer: B
Explanation:
To apply changes to a systemd service unit file, the administrator needs to reload the systemd daemon using the command systemct1 daemon-reload (B). This will make systemd aware of the new or changed unit files.
The other commands will not reload the systemd daemon or apply the changes. References:
* [CompTIA Linux+ Study Guide], Chapter 7: Managing System Services, Section: Modifying Systemd Services
* [How to Reload Systemd Services]
NEW QUESTION # 344
A Linux administrator created a new file system. Which of the following files must be updated to ensure the filesystem mounts at boot time?
- A. /etc/sysctl
- B. /etc/fstab
- C. /etc/nfsmount.conf
- D. /etc/filesystems
Answer: B
Explanation:
The file that must be updated to ensure the filesystem mounts at boot time is /etc/fstab. This file contains information about the filesystems that are mounted automatically by the mount -a command, which is usually invoked during the system startup. The /etc/fstab file has six fields for each filesystem: device name, mount point, filesystem type, mount options, dump frequency, and pass number. To add a new filesystem to the /etc/fstab file, you need to specify these fields correctly and make sure the mount point directory exists.
The other options are not correct files for controlling persistent mount points of filesystems. The /etc/sysctl file is used to configure kernel parameters at runtime. The /etc/filesystems file is used to specify the order of filesystem types used by mount when no filesystem type is given. The /etc/nfsmount.conf file is used to set options for mounting NFS filesystems. Reference: Persistently mounting file systems; fstab(5) - Linux manual page
