LPIC-1 Linux Installation and Package Management Practice Test 4 — 15 Questions

Question 1

Which THREE package management tools are native to Debian-based Linux distributions? (Choose exactly three.)

Accepted Answer

dpkg. dpkg is the core low-level package manager for Debian-based distributions, handling the installation, removal, and querying of .deb packages directly. It does not resolve dependencies automatically, making it the foundational tool upon which higher-level tools like APT are built.

Answer

rpm

Answer

yum

Question 2

Based on the dpkg -l output in the exhibit, what does the 'rc' status indicate for the apache2 package?

Accepted Answer

The package was removed but configuration files remain.. In dpkg, the 'rc' status means the package has been removed (the 'r' flag) but its configuration files remain on the system (the 'c' flag). This occurs when you use 'apt-get remove' or 'dpkg -r' without the --purge option, leaving behind files like /etc/apache2/*. The 'c' indicates that the package's conffiles (as listed in its control data) have not been deleted, allowing for potential reinstallation with previous settings preserved.

Answer

The package is unpacked but not configured.

Answer

The package is installed and configured.

Answer

The package is completely purged.

Question 3

The exhibit shows output from an RPM query on a RHEL 8 system. The installation time is shown as a Unix timestamp. Which command would display the installation date of the openssh-server package in a human-readable format?

Accepted Answer

rpm -qi openssh-server. `rpm -qi` (query info) displays detailed metadata for the specified package, including the installation date in a human-readable format. The `-i` flag retrieves information such as the installation date, build date, and other package metadata, converting Unix timestamps to a readable date string.

Answer

rpm -q --dump openssh-server

Answer

rpm -q --changelog openssh-server

Answer

rpm -q --scripts openssh-server

Question 4

Refer to the exhibit. Based on the apt-cache showpkg output, which version of vim would be installed if the administrator runs 'apt-get install vim' without specifying a version?

Accepted Answer

2:8.2.3995-1ubuntu2.1 from focal-updates. When no version is specified, apt-get install selects the highest version number from the highest-priority repository. Here, version 2:8.2.3995-1ubuntu2.1 is higher than 2:8.2.3995-1ubuntu1, and focal-updates typically has a higher priority than focal (unless overridden by pinning). Therefore, the candidate version from focal-updates (option D) is installed.

Answer

2:8.2.3995-1ubuntu1 from focal-updates

Answer

2:8.2.3995-1ubuntu2.1 from focal

Answer

2:8.2.3995-1ubuntu1 from focal

Question 5

A system administrator needs to install a package 'foo' which depends on library 'libbar.so.2' that is not currently installed. The administrator runs `apt-get install foo` and receives an error about unmet dependencies. Which of the following is the most appropriate next step?

Accepted Answer

Run `apt-get install -f` to fix broken dependencies.. `apt-get install -f` (or `apt --fix-broken install`) attempts to correct a system with broken dependencies by installing missing packages or removing conflicting ones. In this scenario, the unmet dependency is `libbar.so.2`, and running this command will automatically resolve the dependency chain by installing the required library package, assuming it is available in the configured repositories.

Answer

Use `dpkg --force-depends -i foo.deb` to force installation.

Answer

Run `apt-get update` and retry the installation.

Answer

Manually download `libbar.so.2` and install it using `dpkg -i`.

Question 6

An administrator wants to remove a package 'apache2' but keep its configuration files on the system. Which command should be used?

Accepted Answer

`apt-get remove apache2`. `apt-get remove apache2` removes the package binaries but leaves the configuration files (under /etc/apache2/) intact. This is the standard behavior of the `remove` subcommand in APT and dpkg, allowing the administrator to reinstall the package later with the same settings.

Answer

`dpkg --purge apache2`

Answer

`apt-get purge apache2`

Answer

`apt-get autoremove apache2`

Question 7

A developer downloads the source code for a kernel module and attempts to compile it using `make`. The compilation fails with an error indicating that the kernel header files are missing. Which package should be installed to provide the necessary headers on a Debian system?

Accepted Answer

`linux-headers-$(uname -r)`. The correct package is `linux-headers-$(uname -r)` because kernel modules must be compiled against headers that match the exact running kernel version. The `$(uname -r)` command substitution dynamically inserts the current kernel release string (e.g., `5.10.0-28-amd64`), ensuring the headers correspond to the active kernel. On Debian, these headers are provided by the `linux-headers-` package, which includes the necessary `Kbuild`, `Kconfig`, and header files under `/usr/src/linux-headers-`.

Answer

`kernel-headers-generic`

Answer

`build-essential`

Answer

`linux-kernel-headers`

Question 8

A technician needs to add the official Debian repository for the 'buster' release. Which line should be added to /etc/apt/sources.list?

Accepted Answer

`deb http://deb.debian.org/debian buster main`. It uses the standard 'deb' prefix for binary packages, points to the official Debian repository at http://deb.debian.org/debian, specifies the release codename 'buster', and includes the required component 'main'. This is the exact format required by APT to fetch packages for the Debian buster release.

Answer

`deb http://deb.debian.org/debian buster-updates main`

Answer

`deb-src http://deb.debian.org/debian buster main`

Answer

`rpm http://deb.debian.org/debian buster main`

Question 9

A system administrator needs to find out which package installed the file /usr/bin/foo on a Red Hat system. Which command should be used?

Accepted Answer

`rpm -qf /usr/bin/foo`. The `rpm -qf /usr/bin/foo` command queries the RPM database to determine which installed package owns the specified file. The `-f` (or `--file`) option tells RPM to search for the package that provided that file path, making it the correct choice for this task on a Red Hat system.

Answer

`rpm -qa /usr/bin/foo`

Answer

`rpm -qi /usr/bin/foo`

Answer

`rpm -ql /usr/bin/foo`

Question 10

An administrator suspects that a critical system file has been modified after installation. Which command can be used to verify the integrity of all installed RPM packages on a RHEL system?

Accepted Answer

`rpm -Va`. (`rpm -Va`) is correct because it verifies all installed RPM packages against their original metadata, checking file sizes, permissions, checksums, and other attributes. The `-V` flag triggers verification, and `-a` applies it to every installed package, making it the proper command to detect modifications to critical system files.

Answer

`rpm -K`

Answer

`rpm --verify`

Answer

`rpm -V all`

Question 11

An administrator needs to downgrade a package from version 2.0 to version 1.9. Which apt-get command can be used to perform this action?

Accepted Answer

`apt-get install package=1.9`. The correct command is `apt-get install package=1.9` because in APT, the `install` command is used not only to install new packages but also to downgrade an existing package to a specific version by appending `=version` to the package name. This instructs APT to resolve dependencies and perform the downgrade, overriding the currently installed version.

Answer

`apt-get downgrade package=1.9`

Answer

`apt-get upgrade package=1.9`

Answer

`apt-get dist-upgrade package=1.9`

Question 12

A dependency analysis shows that removing package 'libfoo' will also remove 'appA' and 'appB' because they depend on libfoo. The administrator wants to remove libfoo but keep appA and appB. What is the best approach?

Accepted Answer

Check if a compatible alternative package exists and install it, then remove libfoo.. The best approach is to find a compatible alternative package that provides the same functionality as libfoo and can satisfy the dependencies of appA and appB, then install it before removing libfoo. The other options are flawed: `--no-dep` option does not exist, recompiling both applications is time-consuming and risky, and force removal would break the dependent applications.

Answer

Force removal of libfoo using `dpkg --force-depends`.

Answer

Recompile appA and appB without the dependency on libfoo.

Answer

Use `apt-get remove libfoo --no-dep`

Question 13

On a Fedora system, which command is used to update all installed packages to their latest versions?

Accepted Answer

`dnf upgrade`. On Fedora, `dnf upgrade` is the correct command to update all installed packages to their latest versions. It synchronizes the local package database with the repositories and upgrades every installed package that has a newer version available, handling dependencies automatically.

Answer

`dnf check-update`

Answer

`dnf update all`

Answer

`dnf install update`

Question 14

Which two commands can be used to list all packages that have the string 'kernel' in their name on a Debian system? (Choose two.)

Accepted Answer

`apt list --installed '*kernel*'`. `apt list --installed '*kernel*'` uses the APT package manager to list all installed packages whose names match the glob pattern `*kernel*`. Option B is correct because `dpkg -l '*kernel*'` uses the dpkg low-level tool with the `-l` (list) flag and a glob pattern to display all packages whose names contain 'kernel'. Both commands directly filter by package name on a Debian system.

Answer

`dpkg --get-selections | grep kernel`

Answer

`apt-cache search kernel`

Answer

`rpm -qa | grep kernel`

Question 15

Which three options are valid ways to install a package 'curl' on a RHEL 8 system? (Choose three.)

Accepted Answer

`dnf install curl`. `dnf` is the default package manager on RHEL 8, replacing `yum` for handling RPM packages with automatic dependency resolution. It directly installs the `curl` package from configured repositories.

Answer

`apt-get install curl`

Answer

`zypper install curl`
