CompTIA Linux+ Certification Exam Sample Questions (Q372-Q377):

NEW QUESTION # 372
A Linux administrator needs to harden a system and guarantee that the Postfix service will not run, even after a restart or system upgrade. Which of the following commands allows the administrator to fulfill the requirement?

  • A. systemctl mask postfix.service
  • B. systemctl stop postfix.service
  • C. systemctl -n restart postfix.service
  • D. systemctl disable postfix.service

Answer: A

Explanation:
The systemctl mask postfix.service command prevents the Postfix service from being started manually or automatically by symlinking its service file to /dev/null. This ensures that even if a system restart or upgrade occurs, the service will remain disabled and will not start.


NEW QUESTION # 373
An administrator completed the configuration of the in-addr.arpazone files for an organization.
Which of the following commands should the administrator use to verify the configuration is working as expected?

  • A. dig -x 192.168.1.100
  • B. host in-add.arpa
  • C. tracepath -n 192.168.1.100
  • D. ping -n 192.168.1.100
  • E. nslookup in-addr.arpa

Answer: A


NEW QUESTION # 374
A network administrator issues the dig www.comptia.org command and receives an NXDOMAIN response. Which of the following files should the administrator check first?

  • A. /etc/hosts
  • B. /etc/resolv.conf
  • C. /etc/sysconfig/network-scripts
  • D. /etc/nsswitch.conf

Answer: B

Explanation:
Step-by-Step Comprehensive Detailed
Command
The dig command queries DNS servers. If NXDOMAIN is received, the system cannot resolve the domain. The /etc/resolv.conf file contains the DNS server configuration.
Why Other Options are Incorrect:
B: /etc/hosts maps IP addresses to hostnames but is not queried unless configured in /etc/nsswitch.conf.
C: /etc/sysconfig/network-scripts contains network interface configurations, unrelated to DNS.
D: /etc/nsswitch.conf defines the order of name resolution methods, but it does not directly resolve domain names.

NEW QUESTION # 375
A Linux administrator is trying to remove the ACL from the file /home/user/data. txt but receives the following error message:

Given the following analysis:

Which of the following is causing the error message?

  • A. The administrator is not using a highly privileged account.
  • B. File attributes are preventing file modification.
  • C. The filesystem is mounted with the wrong options.
  • D. SELinux file context is denying the ACL changes.

Answer: B

Explanation:
File attributes are preventing file modification, which is causing the error message. The output of lsattr /home
/user/data.txt shows that the file has the immutable attribute (i) set, which means that the file cannot be changed, deleted, or renamed. The command setfacl -b /home/user/data.txt tries to remove the ACL from the file, but fails because of the immutable attribute. The administrator needs to remove the immutable attribute first by using the command chattr -i /home/user/data.txt and then try to remove the ACL again. The other options are incorrect because they are not supported by the outputs. The administrator is using a highly privileged account, as shown by the # prompt. The filesystem is mounted with the correct options, as shown by the output of mount | grep /home. SELinux file context is not denying the ACL changes, as shown by the output of ls -Z /home/user/data.txt.

NEW QUESTION # 376
User1 is a member of the accounting group. Members of this group need to be able to execute but not make changes to a script maintained by User2. The script should not be accessible to other users or groups. Which of the following will give proper access to the script?

  • A. chown user2:accounting script.shchmod 750 script.sh
  • B. chown user1:accounting script.shchmod 777 script.sh
  • C. chown user2:accounting script.shchmod u+x script.sh
  • D. chown accounting:user1 script.shchmod 057 script.sh

Answer: A

Explanation:
The commands that will give proper access to the script are:
chown user2:accounting script.sh: This command will change the ownership of the script to user2 as the owner and accounting as the group. The chown command is a tool for changing the owner and group of files and directories on Linux systems. The user2:accounting is the user and group name that the command should assign to the script. The script.sh is the name of the script that the command should modify. The command chown user2:accounting script.sh will ensure that user2 is the owner of the script and accounting is the group of the script, which will allow user2 to maintain the script and the accounting group to access the script.
chmod 750 script.sh: This command will change the permissions of the script to 750, which means read, write, and execute for the owner; read and execute for the group; and no access for others. The chmod command is a tool for changing the permissions of files and directories on Linux systems. The permissions are represented by three digits in octal notation, where each digit corresponds to the owner, group, and others. Each digit can have a value from 0 to 7, where each value represents a combination of read, write, and execute permissions. The 750 is the permission value that the command should assign to the script. The script.sh is the name of the script that the command should modify. The command chmod 750 script.sh will ensure that only the owner and the group can execute the script, but not make changes to it, and that the script is not accessible to other users or groups.
The commands that will give proper access to the script are chown user2:accounting script.sh and chmod 750 script.sh. This is the correct answer to the question. The other options are incorrect because they either do not give proper access to the script (chown user1:accounting script.sh or chown accounting:user1 script.sh) or do not change the permissions of the script (chmod 777 script.sh or chmod u+x script.sh).
