NEW QUESTION # 102
A systems administrator is creating a backup copy of the /home/directory.
Which of the following commands allows the administrator to archive and compress the directory at the same time?
Answer: C
NEW QUESTION # 103
A DevOps engineer needs to create a local Git repository. Which of the following commands should the engineer use?
Answer: D
Explanation:
Version control is a core DevOps practice, and CompTIA Linux+ V8 includes Git fundamentals as part of automation and orchestration objectives. To create a new local Git repository, the correct command is git init.
The git init command initializes a new Git repository in the current directory by creating a hidden .git directory. This directory contains all the metadata required for version control, including commit history, branches, configuration settings, and object storage. After running git init, the directory becomes a fully functional local repository ready to track files and commits.
The other options do not create a new repository. git clone is used to copy an existing remote repository to a local system, not to create a new one. git config is used to set Git configuration values such as username, email, or default editor. git add stages files for commit but only works after a repository has already been initialized.
Linux+ V8 documentation highlights git init as the foundational command for starting version control in new projects. This command is frequently used in DevOps workflows when creating infrastructure-as-code repositories, automation scripts, or application source trees from scratch.
By initializing a local repository, engineers can begin tracking changes, collaborating with others, and integrating Git into CI/CD pipelines. Therefore, the correct answer is A. git init.
NEW QUESTION # 104
An administrator must secure an account for a user who is going on extended leave. Which of the following steps should the administrator take? (Choose two)
Answer: C,E
Explanation:
Comprehensive and Detailed 250 to 350 words of Explanation From Linux+ V8 documents:
Securing dormant or temporarily unused user accounts is a best practice emphasized in the Security domain of CompTIA Linux+ V8. When a user goes on extended leave, the goal is to prevent unauthorized access while preserving the user's data and account for future use.
The most effective approach is to disable authentication and interactive login access without deleting the account. Option D, running passwd -l user, locks the user's password by prepending an invalid character to the encrypted password in /etc/shadow. This prevents password-based authentication while retaining the account, files, and ownership information. Linux+ V8 documentation highlights password locking as a standard method for temporarily disabling accounts.
Option F, changing the user's shell to /sbin/nologin, further strengthens account security by preventing interactive shell access entirely. Even if another authentication mechanism were attempted, the user would be denied a login shell. This is a common defense-in-depth measure and is explicitly referenced in Linux+ V8 objectives for access control and account hardening.
The other options are incorrect or inappropriate. Option A (immutable files) does not prevent account access and may interfere with system operations. Option B defeats the purpose of securing an inactive account.
Option C deletes user data, which is unnecessary and risky. Option E has no security effect, as filesystem timestamps do not control access.
Linux+ V8 stresses that secure account management should be reversible, auditable, and minimally disruptive. Locking the password and disabling the login shell meet these criteria and are commonly used together in enterprise environments.
NEW QUESTION # 105
Which of the following utilities supports the automation of security compliance and vulnerability management?
Answer: B
Explanation:
OpenSCAP is a framework that automates security compliance checking and vulnerability management by using standardized security content (SCAP). It helps administrators enforce policies and detect vulnerabilities.
NEW QUESTION # 106
A Linux engineer needs to record new changes completed on a Git repository. Which of the following commands should the engineer use?
Answer: B
Explanation:
This command records the staged changes in the local repository by creating a new commit, preserving a snapshot of the work and its history.
