CompTIA Linux+ Certification Exam Sample Questions (Q402-Q407):

NEW QUESTION # 402
A systems administrator configured firewall rules using firewalld. However, after the system is rebooted, the firewall rules are not present:

The systems administrator makes additional checks:

Which of the following is the reason the firewall rules are not active?

  • A. iptables is conflicting with firewalld.
  • B. The wrong system target is activated.
  • C. The firewalld service is not enabled.
  • D. FIREWALL_ARGS has no value assigned.

Answer: C

Explanation:
The reason the firewall rules are not active is that the firewalld service is not enabled. This means that the service will not start automatically at boot time or after a system reload. To enable the firewalld service, the systems administrator needs to use the command sudo systemct1 enable firewalld. This will create a symbolic link from the firewalld service file to the appropriate systemd target, such as multi-user.target. Enabling the service does not start it immediately, so the systems administrator also needs to use the command sudo systemct1 start firewalld or sudo systemct1 reload firewalld to activate the firewall rules.
The other options are not correct reasons for the firewall rules not being active. iptables is not conflicting with firewalld, because firewalld uses iptables as its backend by default. The wrong system target is not activated, because firewalld is independent of the system target and can be enabled for any target. FIREWALL_ARGS has no value assigned, but this is not a problem, because FIREWALL_ARGS is an optional environment variable that can be used to pass additional arguments to the firewalld daemon, such as --debug or --nofork. If FIREWALL_ARGS is empty or not defined, firewalld will use its default arguments. Reference: firewalld.service(8) - Linux manual page; firewall-cmd(1) - Linux manual page; systemct1(1) - Linux manual page


NEW QUESTION # 403
A systems administrator wants to download a package from a remote server.
Which of the following are the BEST commands to use for this task? (Choose two.)

  • A. nc
  • B. tar
  • C. curl
  • D. zip
  • E. wget
  • F. make

Answer: C,E

Explanation:
NC is wrong because in order to use NC you need to setup the server first listening and then the client can transfer files once that is setup. CURL and WGET are correct.


NEW QUESTION # 404
Ann, a security administrator, is performing home directory audits on a Linux server. Ann issues the su Joe command and then issues the Is command. The output displays files that reside in Ann's home directory instead of Joe's. Which of the following represents the command Ann should have issued in order to list Joe's files?

  • A. sudo Joe
  • B. su - Joe
  • C. visudo Joe
  • D. pkexec joe

Answer: B

Explanation:
The su command is used to switch to another user account on Linux systems. The - option makes the shell a login shell, which means that it will read the profile and environment variables of the target user. Without this option, the shell will retain the environment variables of the original user. This can cause confusion when issuing commands that depend on these variables, such as ls, which uses the $HOME variable to determine the home directory. Therefore, Ann should have issued su - Joe to list Joe's files instead of her own. Reference: [How to Use su Command in Linux with Examples]


NEW QUESTION # 405
A systems administrator detected corruption in the /data filesystem. Given the following output:

Which of the following commands can the administrator use to best address this issue?

  • A. umount /data
    mkfs . xfs /dev/sclcl
    mount /data
  • B. umount /data
    pvs /dev/sdcl
    mount /data
  • C. umount /data
    fsck /dev/ sdcl
    mount / data
  • D. umount /data
    xfs repair /dev/ sdcl
    mount /data

Answer: D

Explanation:
The xfs repair command is used to check and repair an XFS filesystem, which is the type of filesystem used for the /data partition, as shown in the output. The administrator needs to unmount the /data partition before running the xfs repair command on it, and then mount it back after the repair is done. For example: umount
/data; xfs_repair /dev/sdcl; mount /data. The mkfs.xfs command is used to create a new XFS filesystem, which would erase all the data on the partition. The fsck command is used to check and repair other types of filesystems, such as ext4, but not XFS. The pvs command is used to display information about physical volumes in a logical volume manager (LVM) setup, which is not relevant for this issue.


NEW QUESTION # 406
A systems administrator has been tasked with disabling the nginx service from the environment to prevent it from being automatically and manually started. Which of the following commands will accomplish this task?

  • A. systemct1 stop nginx
  • B. systemct1 cancel nginx
  • C. systemct1 disable nginx
  • D. systemct1 mask nginx

Answer: D

Explanation:
The command systemct1 mask nginx disables the nginx service from the environment and prevents it from being automatically and manually started. This command creates a symbolic link from the service unit file to
/dev/null, which makes the service impossible to start. This is the correct way to accomplish the task. The other options are incorrect because they either do not exist (systemct1 cancel nginx), do not prevent manual start (systemct1 disable nginx), or do not prevent automatic start (systemct1 stop nginx).
