質問 # 119
A systems administrator needs to restore a backup to the /usr/app/data directory. Which of the following commands should the administrator use for this task?
正解：D
解説：
The tar (tape archive) utility is the standard tool for archiving and compressing files in Linux.
According to CompTIA Linux+ V8 objectives, administrators must be proficient in extracting data into specific target locations. The command tar -xvzf /tmp/backup.tar.gz -C /usr/app/data is the correct syntax for this operation.
The flags used in the command provide the following functionality:
-x: Instructs tar to extract the contents of the archive.
-v: Enables verbose output, showing the files as they are being extracted.
-z: Tells tar to filter the archive through gzip for decompression (required for .tar.gz files).
-f: Specifies the filename of the archive to be processed (/tmp/backup.tar.gz).
-C: Changes the directory to the specified path (/usr/app/data) before performing the extraction.
Using the -C flag is the most efficient and recommended way to restore a backup to a directory other than the current working directory. Without this flag, tar would extract the files into the current directory, which might not be the intended destination and could clutter the filesystem.
質問 # 120
A Linux user frequently tests shell scripts located in the /home/user/scriptsdirectory. Which of the following commands allows the user to run the program by invoking only the script name?
正解：C
解説：
By appending /home/user/scripts to the PATH environment variable, the user can execute scripts from that directory by simply typing the script name without specifying the full path.
質問 # 121
A Linux administrator wants to make the enable_auth variable set to 1 and available to the environment of subsequently executed commands. Which of the following should the administrator use for this task?
正解：B
質問 # 122
Which of the following best describes a use case for playbooks in a Linux system?
正解：B
解説：
In the context of Linux automation and orchestration, playbooks are most commonly associated with configuration management tools such as Ansible, which is explicitly referenced in the CompTIA Linux+ V8 objectives. Playbooks are written in YAML and are designed to define a series of tasks, configurations, and desired system states that should be applied to one or more Linux systems in a repeatable and automated manner.
A primary use case for playbooks is application deployment and system configuration automation. Playbooks allow administrators to specify tasks such as installing packages, configuring services, managing users, setting permissions, deploying application files, and starting or enabling services. This aligns directly with option A, which accurately describes playbooks as a method to provide a set of tasks and configurations required to deploy an application consistently across environments.
The remaining options are not accurate representations of playbook functionality. Option B refers to version control implementation, which is handled by tools like Git and is not the purpose of playbooks themselves, although playbooks may be stored in version control systems. Option C describes container security information, which is typically managed through container runtime configurations, secrets, or security policies rather than playbooks. Option D refers to storage volume information for a pod, which is specific to Kubernetes manifests and not a general Linux playbook use case.
According to Linux+ V8 documentation, automation tools and playbooks help reduce human error, improve consistency, and support Infrastructure as Code (IaC) practices. Playbooks are a key mechanism for orchestrating multi-step operations across multiple systems, making them essential for modern Linux system administration.
Therefore, the correct answer is A, as it best describes the practical and documented use case for playbooks in a Linux system.
質問 # 123
Users cannot access a server after it has been restarted. At the server console, the administrator runs the following commands;
Which of the following is the cause of the issue?
正解：D
解説：
This issue is a classic example of post-reboot connectivity troubleshooting, which falls under the Troubleshooting domain of CompTIA Linux+ V8. The administrator has correctly gathered evidence using multiple diagnostic tools, allowing the root cause to be identified through correlation.
The ss -lnt output confirms that the SSH daemon is running and listening on TCP port 22. This eliminates the possibility that the SSH service failed to start after reboot. Additionally, the uptime output shows a very low load average, indicating that system performance is not a limiting factor. The successful ping test confirms that the server is reachable at the network layer and that DNS resolution and basic connectivity are functioning correctly.
The critical clue comes from the firewall configuration. The output of firewall-cmd --list-all shows that only specific services are allowed through the firewall, such as https, dns, and cockpit. The SSH service is notably absent. On systems using firewalld, services must be explicitly allowed, even if the daemon itself is running and listening on the correct port.
As a result, incoming SSH connection attempts are being blocked by the firewall, preventing users from accessing the server remotely after reboot. This aligns precisely with option B.
The other options are incorrect. DNS is functioning, as shown by successful ping responses. System load is low and not contributing to the issue. There is no indication that users are attempting to access the web server using an incorrect protocol.
Linux+ V8 documentation emphasizes that administrators must verify both service status and firewall rules when diagnosing access issues. In this case, allowing SSH with a command such as firewall-cmd --add- service=ssh --permanent followed by a reload would resolve the problem.
