Homework Help: Questions and Answers: What is a common reason for a network service to fail to start?
A) Incorrect network cable connections
B) Outdated operating system
C) Network interface card (NIC) not installed
D) Network configuration files not properly configured
Answer
To solve this question, let’s analysis each of the given options to determine the common reason why a network service might fail to start.
Given Options: Step by Step Answering
a) Incorrect network cable connections
- Network services generally do not depend on physical cable connections to start. They might fail to work properly if the cables are not connected, but this would not prevent the service from starting.
b) Outdated operating system
- An outdated operating system might cause compatibility issues or security vulnerabilities, but it typically would not directly prevent a network service from starting.
c) Network interface card (NIC) not installed
- If the NIC is not installed, this would indeed prevent the system from being able to use the network, but it might not directly prevent a network service from starting, depending on the service.
d) Network configuration files not properly configured
- Network services rely on correct configuration to start and operate properly. If the configuration files are not properly configured, the service might fail to start because it doesn’t have the correct settings to run.
Final Answer
Among the given options, the most common and direct reason a network service might fail to start is due to incorrect or improperly configured network configuration files. Therefore the correct answer is:
D) Network configuration files not properly configured
This is the most common reason for a network service to fail to start. The network configuration files, such as those found in /etc/network/ or /etc/systemd/network/, need to be properly set up with the correct IP addresses, subnet masks, gateways, and other parameters. If these files are misconfigured, the network service will not be able to start successfully.
