CompTIA Linux+ Certification Exam 認定 XK0-005 試験問題 (Q270-Q275):

質問 # 270
A systems engineer is adding a new 1GB XFS filesystem that should be temporarily mounted under /ops/app.
Which of the following is the correct list of commands to achieve this goal?

正解：A

解説：
Explanation
The list of commands in option D is the correct way to achieve the goal. The commands are as follows:
fallocate -l 1G /ops/app.img creates a 1GB file named app.img under the /ops directory.
mkfs.xfs /ops/app.img formats the file as an XFS filesystem.
mount -o loop /ops/app.img /ops/app mounts the file as a loop device under the /ops/app directory. The other options are incorrect because they either use the wrong commands (dd or truncate instead of fallocate), the wrong options (-t or -f instead of -o), or the wrong order of arguments (/ops/app.img
/ops/app instead of /ops/app /ops/app.img). References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 10: Managing Storage, pages 323-324.

質問 # 271
A Linux administrator is troubleshooting the root cause of a high CPU load and average.

Which of the following commands will permanently resolve the issue?

A. kill -9 6295
B. pstree -p 6295
C. renice -n -20 6295
D. iostat -cy 1 5

正解：A

解説：
Explanation
The command that will permanently resolve the issue of high CPU load and average is kill -9 6295. This command will send a SIGKILL signal to the process with the PID 6295, which is the process that is consuming 99.7% of the CPU according to the top output. The SIGKILL signal will terminate the process immediately and free up the CPU resources. The kill command is used to send signals to processes by PID or name.
The other options are not correct commands for resolving this issue. The renice -n -20 6295 command will change the priority (niceness) of the process with PID 6295 to -20, which is the highest priority possible. This will make the process more CPU-intensive, not less. The renice command is used to change the priority of running processes. The pstree -p 6295 command will show a tree of processes with PID 6295 as the root. This will not affect the CPU load or average, but only display information. The pstree command is used to display a tree of processes. The iostat -cy 1 5 command will show CPU and disk I/O statistics for 5 iterations with an interval of 1 second. This will also not affect the CPU load or average, but only display information. The iostat command is used to report CPU and I/O statistics.

質問 # 272
A systems administrator receives reports that several virtual machines in a host are responding slower than expected. Upon further investigation, the administrator obtains the following output from one of the affected systems:

Which of the following best explains the reported issue?

A. The physical host has enough CPU cores, leading to users running more processes to compensate for the slower response times.
B. The virtual machine is running out of CPU resources, leading to users experiencing longer response times.
C. The virtual machine has enough CPU cycles, leading to the system use percentage being higher than expected.
D. The physical host is running out of CPU resources, leading to insufficient CPU time being allocated to virtual machines.

正解：B

解説：
Based on the output from one of the affected systems, the best explanation for the reported issue is that the virtual machine is running out of CPU resources, leading to users experiencing longer response times (D). The output shows that the system use percentage is very high (57.85%), indicating that the virtual machine is using most of its CPU cycles for system processes. This leaves little CPU time for user processes, which results in slower performance. The other explanations are not supported by the output or are contradictory. Reference:

[How to Interpret CPU Usage Statistics]

質問 # 273
A systems administrator is tasked with creating a cloud-based server with a public IP address.

Which of the following technologies did the systems administrator use to complete this task?

A. Git
B. Ansible
C. Puppet
D. Terraform

正解：D

解説：
Explanation
The systems administrator used Terraform to create a cloud-based server with a public IP address. Terraform is a tool for building, changing, and versioning infrastructure as code. Terraform can create and manage resources on different cloud platforms, such as AWS, Azure, or Google Cloud. Terraform uses a declarative syntax to describe the desired state of the infrastructure and applies the changes accordingly. Terraform can also assign a public IP address to a cloud server by using the appropriate resource attributes. This is the correct technology that the systems administrator used to complete the task. The other options are incorrect because they are either not designed for creating cloud servers (Puppet or Git) or not capable of assigning public IP addresses (Ansible). References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 19:
Managing Cloud and Virtualization Technologies, page 559.

質問 # 274
A systems administrator is encountering performance issues. The administrator runs 3 commands with the following output

The Linux server has the following system properties
CPU: 4 vCPU
Memory: 50GB
Which of the following accurately describes this situation?

A. The system is under CPU pressure and will require additional vCPUs
B. The system has been running for over a year and requires a reboot.
C. The system requires more memory
D. Too many users are currently logged in to the system

正解：B
