질문 # 107
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?
정답：A
설명：
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.
질문 # 108
Due to application compatibility issues, the Python 3 OpenSSL library should not be upgraded. Which of the following commands should the systems administrator use to ensure the package stays at the current version?
정답：C
설명：
Package management is a critical system management task covered extensively in the Linux+ V8 objectives.
On Debian-based systems (like Ubuntu), administrators often need to " pin " or " hold " a specific package version to prevent it from being automatically updated during a general system upgrade (apt upgrade). This is commonly done to avoid breaking applications that have strict version dependencies.
The modern and most direct way to accomplish this is using the apt-mark utility. The command apt-mark hold
< package_name > marks the package as " on hold " in the package manager database. Once a package is on hold, apt will skip it during upgrades until an administrator explicitly runs apt-mark unhold.
While Option D (echo " package hold " | dpkg --set-selections) is a valid legacy method, apt-mark hold (Option C) is the preferred and more user-friendly standard in contemporary Linux administration. Option A has incorrect syntax for dpkg. Option B uses a non-existent command (set-selections is a sub-module of dpkg, not apt).
Therefore, apt-mark hold is the verified correct answer for ensuring a package remains at its current version.
질문 # 109
Which of the following is the first step when starting a new Python project on a Linux system?
정답：D
설명：
The correct answer is A. python -m venv /path/to/project because creating a virtual environment is the recommended first step when starting a new Python project. A virtual environment isolates project dependencies from the system-wide Python installation, ensuring that libraries and package versions do not conflict with other projects or system components.
The command python -m venv /path/to/project creates a self-contained directory that includes its own Python interpreter, libraries, and scripts. This allows developers and administrators to install packages specific to the project without affecting the global environment. After creating the virtual environment, the next steps typically include activating it (e.g., source /path/to/project/bin/activate) and then installing dependencies using pip.
Option B (python -m pip install -r /path/to/project) is incorrect because installing dependencies from a requirements file assumes that a virtual environment or project structure is already in place. It is not the first step.
Option C (export PYTHON_PATH=/path/to/project) is incorrect because setting PYTHONPATH only modifies where Python looks for modules. It does not create an isolated environment or manage dependencies.
Option D (python -m source /path/to/project) is incorrect because source is a shell built-in command used to activate environments, not a Python module, and this syntax is invalid.
From a Linux+ perspective, using virtual environments aligns with best practices in automation and scripting.
It ensures consistency, reproducibility, and isolation of development environments, which is critical for deployment, testing, and maintaining Python-based applications.
질문 # 110
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：B
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 # 111
An administrator has generated an RSA SSH key pair to log in to a remote server. After copying the public key and attempting to log in, the administrator sees the following message:
admin@192.168.10.50: Permission denied (publickey,password)
After seeing the message, the administrator attempts to connect using ssh -v admin@192.168.10.50 and notices the following debug output:
debug1: send_pubkey_test: no mutual signature algorithm
Which of the following actions should the administrator take first to remediate this issue?
정답：D
설명：
The "no mutual signature algorithm" error means the RSA/SHA-1 key type (ssh-rsa) isn't supported by both client and server. Generating a new key with a modern algorithm (e.g., ssh- keygen -t ecdsa) ensures a mutually supported signature method.
