✕Common Mistakes
Fait un diagnostic réseau.
‘Fait’ is the past participle of ‘faire’; the correct imperative form is ‘fais’.
Fais un diagnostique réseau.
‘Diagnostique’ is a verb; you need the noun ‘diagnostic’ after the article.
Fais le diagnostic réseau.
The indefinite article ‘un’ is required because you are referring to any diagnostic, not a specific one.

Cultural Tip
In French professional settings, the imperative can sound abrupt. Adding 's'il te plaît' or using the conditional 'pourriez‑vous' softens the request. Also, the term 'diagnostic' is widely used in IT, but you may also hear 'analyse du réseau' in more formal reports.
