Bem, antes de estudar você precisará coletar o material para poder estudar. O que acontece é que muitos iniciantes, quando fazem seu curso de Linux, não sabem o que estudar especificamente, não sabem que a LPI define objetivos para cada uma de suas provas e acham que quanto mais eles souberem sobre o mundo Linux, mais eles estarão aptos a fazer o exame.

De certa forma sim, porém para se passar em qualquer prova de certificação é necessário que você estude especificamente dentro dos objetivos que a empresa que aplica o teste especifica.

Os objetivos cobrados pela LPI podem ser vistos no site da LPI.
