CompTIA Linux+ Certification Exam Sample Questions (Q830-Q835):NEW QUESTION # 830
Several users reported that they were unable to write data to the /oracle1 directory. The following output has been provided:

Which of the following commands should the administrator use to diagnose the issue?
  • A. fdisk -1 /dev/sdb1
  • B. df -i /oracle1
  • C. du -sh /oracle1
  • D. lsblk /dev/sdb1
Answer: B
Explanation:
The administrator should use the command df -i /oracle1 to diagnose the issue of users being unable to write data to the /oracle1 directory. This command will show the inode usage of the /oracle1 filesystem, which indicates how many files and directories can be created on it. If the inode usage is 100%, it means that no more files or directories can be added, even if there is still free space on the disk. The administrator can then delete some unnecessary files or directories, or increase the inode limit of the filesystem, to resolve the issue.
The other options are not correct commands for diagnosing this issue. The fdisk -l /dev/sdb1 command will show the partition table of /dev/sdb1, which is not relevant to the inode usage. The lsblk /dev/sdb1 command will show information about /dev/sdb1 as a block device, such as its size, mount point, and type, but not its inode usage. The du -sh /oracle1 command will show the disk usage of /oracle1 in human-readable format, but not its inode usage. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 7:

NEW QUESTION # 831
A user is unable to log on to a Linux workstation. The systems administrator executes the following command:
cat /etc/shadow | grep user1
The command results in the following output:
user1 :! $6$QERgAsdvojadv4asdvaarC/9dj34GdafGVaregmkdsfa:18875:0:99999:7 :::
Which of the following should the systems administrator execute to fix the issue?
  • A. chgrp user1:user1 /home/user1
  • B. sed -i '/ ::: / :: /g' /etc/shadow
  • C. chown -R userl:user1 /home/user1
  • D. passwd -u user1
Answer: D
Explanation:
Explanation
The output shows that the user1 account has a locked password, indicated by the exclamation point (!) in the second field of the /etc/shadow file1. To unlock the password and allow the user to log in, the systems administrator should use the passwd command with the -u (unlock) option2.

NEW QUESTION # 832
A Linux administrator found many containers in an exited state. Which of the following commands will allow the administrator to clean up the containers in an exited state?
  • A. docker rm -- all
  • B. docker rm -- state exited
  • C. docker rm $ (docker ps -aq)
  • D. docker images prune *
Answer: C
Explanation:
This command will remove all containers, regardless of their state, by passing the IDs of all containers to the docker rm command. The docker ps -aq command will list the IDs of all containers, including the ones in an exited state, and the $ ( ) syntax will substitute the output of the command as an argument for the docker rm command. This is a quick and easy way to clean up all containers, but it may also remove containers that are still needed or running.

NEW QUESTION # 833
A systems administrator is investigating why one of the servers has stopped connecting to the internet.

Which of the following is causing the issue?
  • A. No default route is defined.
  • B. Wired connection 1 is offline.
  • C. The DNS address has been commented out in the configuration file.
  • D. The search entry in the /etc/resolv.conf file is incorrect.
Answer: A
Explanation:
Explanation
The issue is caused by the lack of a default route defined in the /etc/sysconfig/network-scripts/ifcfg-enp0s3 file. A default route is a special route that specifies where to send packets that do not match any other routes in the routing table. Without a default route, the server will not be able to communicate with hosts outside its local network. The default route is usually configured with the GATEWAY option in the network interface configuration file. For example, to set the default gateway to 192.168.1.1, the file should contain:
GATEWAY=192.168.1.1
The other options are not causing the issue. The DNS address is not commented out in the configuration file, it is specified with the DNS1 option. The search entry in the /etc/resolv.conf file is correct, it specifies the domain name to append to unqualified hostnames. Wired connection 1 is online, as indicated by the ONBOOT=yes option and the output of ip link show enp0s3 command.

  • A. Sync the mount units.
  • B. Mount the filesystem manually.
  • C. Create a mount unit and enable it to be started at boot.
