CompTIA Linux+ Certification Exam Sample Questions (Q199-Q204):
NEW QUESTION # 199
A Linux administrator was notified that a virtual server has an I/O bottleneck. The Linux administrator analyzes the following output:
Given there is a single CPU in the sever, which of the following is causing the slowness?
Answer: A
Explanation:
Explanation
The slowness is caused by the CPU being overloaded. The iostat command shows that the CPU utilization is
100%, which means that there are more processes competing for CPU time than the CPU can handle. The other options are incorrect because:
The system is not running out of swap space, as shown by the iostat command, which shows that there is no swap activity (si and so columns are zero).
The memory is not exhausted, as shown by the free -m command, which shows that there is still available memory (avail column) and free buffer/cache memory (buff/cache column).
The processes are not paging, as shown by the vmstat command, which shows that there are no major page faults (majflt column) and no swap activity (si and so columns). References: CompTIA Linux+ Study Guide, Fourth Edition, page 417-419, 424-425.
NEW QUESTION # 200
A Linux administrator needs to obtain a list of all volumes that are part of a volume group. Which of the following commands should the administrator use to accomplish this task?
Answer: C
Explanation:
The lvs command can be used to obtain a list of all volumes that are part of a volume group. This command will display information such as the name, size, attributes, and volume group of each logical volume in the system. The vgs command can be used to obtain a list of all volume groups in the system, not the volumes. The fdisk -1 command is invalid, as -1 is not a valid option for fdisk. The pvs command can be used to obtain a list of all physical volumes in the system, not the volumes. Reference: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 14: Managing Disk Storage, page 461.
NEW QUESTION # 201
Users report that connections to a MariaDB service are being closed unexpectedly. A systems administrator troubleshoots the issue and finds the following message in /var/log/messages:
Which of the following is causing the connection issue?
Answer: A
NEW QUESTION # 202
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?
Answer: B
Explanation:
In order to limit the login we can add /bin/false to the end of the string (in the file /etc/passwd ), thus we will have a return code = 1 (when the user tries to open the terminal it will close immediately ).
Another method, in the same way, we add /sbin/nologin (in this case I will have the message
"This account is currently not available")
NEW QUESTION # 203
An administrator attempts to rename a file on a server but receives the following error.
The administrator then runs a few commands and obtains the following output:
Which of the following commands should the administrator run NEXT to allow the file to be renamed by any user?
Answer: D
Explanation:
The command that the administrator should run NEXT to allow the file to be renamed by any user is chmod -t files. This command uses the chmod tool, which is used to change file permissions and access modes. The -t option removes (or sets) the sticky bit on a directory, which restricts deletion or renaming of files within that directory to only their owners or root. In this case, since files is a directory with sticky bit set (indicated by t in drwxrwxrwt), removing it will allow any user to rename or delete files within that directory.
The other options are not correct commands for allowing any user to rename files within files directory. The chgrp reet files command will change the group ownership of files directory to reet, but it will not affect its permissions or access modes. The chacl -R 644 files command is invalid, as chacl is used to change file access control lists (ACLs), not permissions or access modes. The chown users files command will change the user ownership of files directory to users, but it will not affect its permissions or access modes.
