질문 # 22
A Linux administrator just finished setting up passwordless SSH authentication between two nodes. However, upon test validation, the remote host prompts for a password. Given the following logs:
Which of the following is the most likely cause of the issue?
정답：A
설명：
This issue is directly related to SELinux enforcement, which is a key topic in the Security domain of CompTIA Linux+ V8. The logs clearly indicate that SSH key-based authentication is failing due to an SELinux access control violation rather than a traditional file permission or SSH configuration problem.
The most important clue is the AVC denial message, which shows that the sshd process is being denied read access to the authorized_keys file. The security context of the file is listed as unconfined_u:object_r:
home_root_t:s0. Under a targeted SELinux policy, SSH is only permitted to read authorized_keys files that are labeled with the correct SELinux type, typically ssh_home_t.
Because SELinux is running in enforcing mode, it actively blocks access that violates policy rules, even if standard UNIX permissions are correct. Although the file permissions (600) are acceptable for an authorized_keys file, SELinux does not rely solely on traditional permissions. The mismatch between the expected SELinux context and the actual context prevents sshd from accessing the file, causing SSH to fall back to password authentication.
Option D correctly identifies the root cause: the authorized_keys file does not have the correct SELinux security context. This is a well-documented Linux+ V8 troubleshooting scenario, commonly resolved by restoring the correct context using commands such as restorecon or by ensuring the file resides in a properly labeled home directory.
The other options are incorrect. Restarting sshd does not fix SELinux labeling issues. The policy itself is functioning as intended, and file ownership alone does not override SELinux access controls.
Linux+ V8 documentation emphasizes that SELinux denials must be addressed by correcting file contexts rather than weakening security controls. Therefore, the correct answer is D.
질문 # 23
A Linux systems administrator needs to extract the contents of a file named /home/dev/web.bkp to the /var
/www/html/ directory. Which of the following commands should the administrator use?
정답：C
설명：
File extraction and backup restoration are fundamental System Management tasks covered in CompTIA Linux+ V8. In this scenario, the administrator must extract the contents of an existing backup file into a target directory.
The correct command is option B, which uses cpio in extract mode. The command changes into the destination directory (/var/www/html/) using pushd, extracts the archive contents with cpio -idv, and then returns to the original directory with popd. This ensures that files are restored into the correct location without modifying paths inside the archive.
The cpio utility is commonly used for backups created with cpio -o and supports reading archive data from standard input. Linux+ V8 documentation includes cpio as a valid and supported archive format for backup and restore operations.
The other options are incorrect. Option A incorrectly assumes the backup is a gzip-compressed tar archive.
Option C creates a new archive instead of extracting one. Option D assumes the file is a ZIP archive, which is not indicated by the .bkp extension.
Linux+ V8 emphasizes using the correct tool based on the archive format and restoring files into the intended directory. Therefore, the correct answer is B.
질문 # 24
Which of the following describes what Ansible is used for in the context of IT Infrastructure?
정답：D
설명：
Ansible is used for configuration management, allowing administrators to automate the provisioning, configuration, and management of systems and services across an IT infrastructure.
질문 # 25
Which of the following best describes a use case for playbooks in a Linux system?
정답：A
설명：
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.
질문 # 26
Which of the following formats is used to write an Ansible playbook?
정답：B
설명：
Ansible playbooks are written in YAML, which provides a human-readable, structured format used to define plays, tasks, variables, and roles for automation.
