Cybersecurity Student Debates Between Broad Infrastructure Labs vs Focused Security Projects

A cybersecurity student is asking whether they should build a range of labs covering network infrastructure, cloud infrastructure, Linux servers, and Active Directory, or focus solely on cybersecurity-specific projects like SIEM labs and TryHackMe. Their classmate told them they're wasting time with the broader infrastructure labs and should focus only on cyber projects. The student believes understanding what they are securing could look better, as cyber students often get criticized for not knowing the underlying systems.
