CompTIA Linux+ Certification Exam Sample Questions (Q674-Q679):

NEW QUESTION # 674
A junior administrator is trying to set up a passwordless SSH connection to one of the servers. The administrator follows the instructions and puts the key in the authorized_key file at the server, but the administrator is still asked to provide a password during the connection.
Given the following output:

Which of the following commands would resolve the issue and allow an SSH connection to be established without a password?

  • A. restorecon -rv .ssh/authorized_key
  • B. chmod 600 mv .ssh/authorized_key
  • C. mv .ssh/authorized_key .ssh/authorized_keys
  • D. systemct1 restart sshd.service

Answer: C

Explanation:
The command mv .ssh/authorized_key .ssh/authorized_keys will resolve the issue and allow an SSH connection to be established without a password. The issue is caused by the incorrect file name of the authorized key file on the server. The file should be named authorized_keys, not authorized_key.
The mv command will rename the file and fix the issue. The other options are incorrect because they either do not affect the file name (restorecon or chmod) or do not restart the SSH service (systemct1).

NEW QUESTION # 675
An administrator is trying to diagnose a performance issue and is reviewing the following output:

System Properties:
CPU: 4 vCPU
Memory: 40GB
Disk maximum IOPS: 690
Disk maximum throughput: 44Mbps | 44000Kbps
Based on the above output, which of the following BEST describes the root cause?

  • A. The system has reached its maximum IOPS, causing the system to be slow.
  • B. The system has a partitioned disk, which causes the IOPS to be doubled.
  • C. The system has reached its maximum permitted throughput, therefore iowait is increasing.
  • D. The system is mostly idle, therefore the iowait is high.

Answer: C

Explanation:
Explanation
The system has reached its maximum permitted throughput, therefore iowait is increasing. The output of iostat
-x shows that the device sda has an average throughput of 44.01 MB/s, which is equal to the disk maximum throughput of 44 Mbps. The output also shows that the device sda has an average iowait of 99.99%, which means that the CPU is waiting for the disk to complete the I/O requests. This indicates that the disk is the bottleneck and the system is slow due to the high iowait. The other options are incorrect because they are not supported by the outputs. The system has not reached its maximum IOPS, as the device sda has an average IOPS of 563.50, which is lower than the disk maximum IOPS of 690. The system is not mostly idle, as the output of top shows that the CPU is 100% busy. The system does not have a partitioned disk, as the output of lsblk shows that the device sda has only one partition sda1.

NEW QUESTION # 676
A Linux administrator cloned an existing Linux server and built a new server from that clone. The administrator encountered the following error after booting the cloned server:

The administrator performed the commands listed below to further troubleshoot and mount the missing filesystem:

Which of the following should administrator use to resolve the device mismatch issue and mount the disk?

  • A. mount disk by-blkid
  • B. mount disk by device-id
  • C. mount disk by-label
  • D. fsck -A

Answer: B

Explanation:
Explanation
The administrator should use the command mount disk by device-id to resolve the device mismatch issue and mount the disk. The issue is caused by the cloned server having a different device name for the disk than the original server. The output of blkid shows that the disk has the device name /dev/sdb1 on the cloned server, but the output of cat /etc/fstab shows that the disk is expected to have the device name /dev/sda1. The command mount disk by device-id will mount the disk by using its unique identifier (UUID) instead of its device name. The UUID can be obtained from the output of blkid or lsblk -f. The command will mount the disk to the specified mount point (/data) and resolve the issue. The other options are incorrect because they either do not mount the disk (fsck -A), do not use the correct identifier (mount disk by-label or mount disk by-blkid), or do not exist (mount disk by-blkid).

  • A. echo "nameserver 192.168.204.11 #Payroll" >> /etc/resolv.conf
  • B. echo "192.168.204.11 Payroll" >> /etc/hosts
  • C. echo `IPADDR="192.168.204.11" #Payroll' >> /etc/network/interface
  • D. echo "net.ipv4.ip_dynaddr=192.168.204.11 Payroll" >> /etc/sysctl.conf

Answer: B
