Welcher Parameter muss an ifconfig übergeben werden, um eine zuvor inaktive Netzwerkschnittstelle zu aktivieren? (Geben Sie den Parameter nur ohne Befehl, Pfad oder zusätzliche Optionen an.)
正解：
up
Explanation:
The parameter that must be passed to ifconfig to activate a previously inactive network interface is up. The up parameter tells the kernel to activate the network interface and allow it to send and receive packets. The opposite of up is down, which deactivates the network interface. The up parameter is part of the topic 109.2: Basic network configuration, which is one of the objectives of the LPI Linux Administrator - 102 exam12.

Die Zeitzone des Systems kann durch Verknüpfen von / etc / localtime mit einer entsprechenden Datei in welchem Verzeichnis festgelegt werden? (Geben Sie den vollständigen Pfad zum Verzeichnis ohne Länderinformationen an.)
正解：
usrsharezoneinfo
Explanation:
The /usr/share/zoneinfo directory contains the binary time zone files that are used by the system to determine the local time for any region. The files are organized in subdirectories by continent, country, or ocean. Some files represent the standard time zones, while others may have historical or political variations. To set the system's timezone, one can create a symbolic link from /etc/localtime to the appropriate file in the /usr/share/zoneinfo directory. For example, to set the timezone to America/New_York, one can use the command sudo ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime. Alternatively, one can use the timedatectl command to set the timezone without creating the link manually. Reference:
