NEW QUESTION # 740
When trying to log in remotely to a server, a user receives the following message:

The server administrator is investigating the issue on the server and receives the following outputs:

Which of the following is causing the issue?
  • A. The wrong permissions are on the user's home directory.
  • B. The user has the wrong shell assigned to the account.
  • C. The account was locked out due to three failed logins.
  • D. The user entered the wrong password.
Answer: B
Explanation:
Explanation
The user has the wrong shell assigned to the account, which is causing the issue. The output 1 shows that the user's shell is set to /bin/false, which is not a valid shell and will prevent the user from logging in. The output
2 shows that the user's home directory has the correct permissions (drwxr-xr-x), and the output 3 shows that the user entered the correct password and was accepted by the SSH daemon, but the session was closed immediately due to the invalid shell. The other options are incorrect because they are not supported by the outputs. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 13: Managing Network Services, page 413.

NEW QUESTION # 741
A junior Linux administrator is tasked with installing an application. The installation guide states the application should only be installed in a run level 5 environment.
Which of the following commands would ensure the server is set to runlevel 5?
  • A. systemct1 isolate basic.target
  • B. systemct1 isolate graphical.target
  • C. systemct1 isolate multi-user.target
  • D. systemct1 isolate network.target
Answer: B
Explanation:
The command that would ensure the server is set to runlevel 5 is systemct1 isolate graphical.target. This command will change the current target (or runlevel) of systemd to graphical.target, which is equivalent to runlevel 5 in SysV init systems. Graphical.target means that the system will start with a graphical user interface (GUI) and all services required for it.
The other options are not correct commands for setting the server to runlevel 5. The systemct1 isolate multi- user.target command will change the current target to multi-user.target, which is equivalent to runlevel 3 in SysV init systems. Multi-user.target means that the system will start with multiple user logins and networking, but without a GUI. The systemct1 isolate network.target command will change the current target to network.
target, which is not a real runlevel but a synchronization point for network-related services. Network.target means that network functionality should be available, but does not specify whether it should be started before or after it. The systemct1 isolate basic.target command will change the current target to basic.target, which is also not a real runlevel but a synchronization point for basic system services. Basic.target means that all essential services should be started, but does not specify whether it should be started before or after it. References: systemd System and Service Manager; systemd.special(7) - Linux manual page

NEW QUESTION # 742
An administrator accidentally deleted the /boot/vmlinuz file and must resolve the issue before the server is rebooted. Which of the following commands should the administrator use to identify the correct version of this file?
  • A. cat /etc/centos-release; rpm -Uvh --nodeps
  • B. telinit 1; restorecon -Rv /boot
  • C. yum -y update; shutdown -r now
  • D. rpm -qa | grep kernel; uname -a
Answer: D
Explanation:
The command rpm -qa | grep kernel lists all the installed kernel packages, and the command uname - a displays the current kernel version. These commands can help the administrator identify the correct version of the /boot/vmlinuz file, which is the kernel image file. The other options are not relevant or helpful for this task. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 8: Managing the Linux Boot Process, page 267.

NEW QUESTION # 743
A systems administrator is tasked with changing the default shell of a system account in order to disable iterative logins. Which of the following is the  best option for the administrator to use as the new shell?
  • A. /bin/ sh
  • B. /sbin/nologin
  • C. /sbin/ setenforce
  • D. /bin/bash
Answer: B
Explanation:
The /sbin/nologin shell is a special shell that prevents the user from logging into an interactive session. It is commonly used for system accounts that are not meant to be accessed by users, such as daemon or service accounts. When a user tries to log in with this shell, they will see a message like "This account is currently not available" and the login will fail.
Reference:
The /sbin/nologin shell is listed as one of the valid shells in the /etc/shells file1.
The CompTIA Linux+ Certification Exam Objectives mention that the candidate should be able to "configure and manage system accounts and groups, including password aging and restricted shells" as part of the Hardware and System Configuration domain2.
The usermod command can be used to change the user's login shell with the -s or --shell option3. For example, to change the shell of a user named daemon to /sbin/nologin, the command would be: sudo usermod -s /sbin/nologin daemon
