질문 # 53
A DevOps engineer made some changes to files in a local repository. The engineer realizes that the changes broke the application and the changes need to be reverted back. Which of the following commands is the best way to accomplish this task?
정답：C
설명：
Version control rollback operations are a core DevOps skill covered in the Linux+ V8 objectives. When changes in a local Git repository break an application and must be reverted, the administrator must choose a command that directly undoes those changes.
The command git reset is the most appropriate option in this scenario. It allows the engineer to move the current branch pointer (HEAD) to a previous commit, effectively discarding or undoing local changes.
Depending on the reset mode (--soft, --mixed, or --hard), the engineer can control whether changes are preserved in the staging area or working directory. This flexibility makes git reset the primary tool for reverting problematic local changes.
The other options are not suitable. git pull fetches and merges changes from a remote repository and does not revert local modifications. git rebase rewrites commit history and is used to reapply commits on top of another base, not to undo broken changes. git stash temporarily saves uncommitted changes for later use but does not revert the repository to a stable state.
Linux+ V8 documentation emphasizes that git reset is commonly used during local development when changes need to be undone quickly before being shared with others. Therefore, the correct answer is B.
질문 # 54
Which of the following commands can be used to display current CPU utilization in real time on a Linux system?
정답：C
설명：
The correct answer is B. top because it provides a real-time, continuously updating view of system performance, including CPU utilization. The top command is one of the most widely used monitoring tools in Linux and is essential for system administrators when analyzing performance issues.
When executed, top displays a dynamic interface showing CPU usage percentages, memory consumption, load averages, running processes, and other critical system metrics. The CPU usage section is particularly useful because it breaks down usage into categories such as user space, system (kernel), idle time, and I/O wait. This allows administrators to quickly identify whether the CPU is under heavy load and which processes are consuming the most resources.
Option A (uptime) is incorrect because it provides load averages but does not give detailed or real-time CPU utilization percentages.
Option C (df) is incorrect because it reports disk space usage, not CPU activity.
Option D (lsblk) is incorrect because it lists block devices and storage structure, not CPU performance.
From a Linux+ system management perspective, tools like top, htop, and vmstat are critical for monitoring system health. Among these, top is the most fundamental and widely available tool for real-time CPU analysis. It enables administrators to detect performance bottlenecks, identify runaway processes, and take corrective action such as terminating processes or reallocating resources.
질문 # 55
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).
정답：A,C
설명：
passwd -l user locks the user's account by disabling the password, preventing logins.
Change the user's shell to /sbin/nologin ensures the account cannot be used for interactive logins, further securing it.
질문 # 56
An administrator updates the network configuration on a server but wants to ensure the change will not cause an outage if something goes wrong. Which of the following commands allows the administrator to accomplish this goal?
정답：C
설명：
netplan try applies the new network configuration temporarily and waits for user confirmation. If not confirmed, it automatically reverts, preventing outages from misconfigurations.
질문 # 57
Which of the following most accurately describes a webhook?
정답：D
설명：
The correct answer is D. An HTTP-based callback function. A webhook is a mechanism that allows one system to automatically send real-time data to another system via HTTP when a specific event occurs. Instead of continuously polling an API for updates, a webhook enables event-driven communication, making automation more efficient and responsive.
In practical Linux and DevOps environments, webhooks are widely used in automation, orchestration, and integration workflows. For example, a version control system like GitHub can trigger a webhook to notify a CI
/CD pipeline whenever new code is pushed. The receiving system exposes an HTTP endpoint (URL), and when the event occurs, the webhook sends an HTTP POST request with relevant data payload. This design significantly reduces overhead compared to polling mechanisms.
Option A is incorrect because webhooks are not authentication mechanisms. While authentication (such as tokens or signatures) may be used to secure webhook communication, it is not their primary purpose.
Option B is incorrect because SNMP (Simple Network Management Protocol) is unrelated to webhooks.
SNMP is used for monitoring and managing network devices, whereas webhooks operate over HTTP/HTTPS protocols.
Option C is incorrect because although webhooks can transmit data (including sensitive information if not properly secured), their purpose is not specifically to transmit sensitive data but to notify systems of events through automated callbacks.
From a Linux+ perspective, understanding webhooks is essential in automation and orchestration tasks. They are commonly integrated into scripts, configuration management tools, and cloud-native workflows to enable reactive, event-driven system behavior, improving efficiency and scalability in modern infrastructure environments.
