LPIC-1 Linux Installation and Package Management Practice Question
A technician is tasked with installing a package from a third-party repository on a CentOS 7 system. What is the correct first step to add the repository?
⚠ Common exam trap
Many candidates confuse editing /etc/yum.conf (which is for global yum options, not repository definitions) with the correct method of adding a .repo file, or they assume 'yum localinstall' can add a repository when it only installs a single package.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a .repo file in /etc/yum.repos.d/.
On CentOS 7, third-party repositories are added by placing a .repo file in /etc/yum.repos.d/. This file defines the repository ID, name, baseurl, and GPG check settings. Yum reads all .repo files in this directory at runtime, making it the standard and correct first step for adding a repository.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run 'yum localinstall' with the repository URL.
Why it's wrong here
localinstall is for RPM files, not adding repositories.
- ✓
Create a .repo file in /etc/yum.repos.d/.
Why this is correct
Repository definitions are placed in /etc/yum.repos.d/ as .repo files.
- ✗
Edit /etc/yum.conf and add the repository URL.
Why it's wrong here
yum.conf holds global settings, not repository definitions.
- ✗
Use 'yum-config-manager --add-repo' without any further steps.
Why it's wrong here
While possible, the question asks for the first step; creating a file is the fundamental method.
