Certification
If registering for the AVIT® Automating Administration With Windows PowerShell certification option, you must do so at the same time as course registration. The exam is a multiple-choice test lasting one-and-a-half to two hours. The result indicates your skill level. Merely taking the course is not sufficient to achieve a maximum score. The exam must be both scheduled and then taken online within 4 weeks following the start of your session.

Practical details
Different exercises (simple and complex) will be carried out in order to become truly autonomous in writing shell scripts.
