Introduction of CompTIA N10-009 Exam!

The N10-009 exam is the current exam for the CompTIA Network+ Certification from CompTIA.

Employers use CompTIA Network+ Certification as a hiring signal for practitioner-level roles, because it shows a candidate can do the work the certification describes, not just describe the theory.
