CompTIA Network+ (N10-008)

CompTIA Network+ (Exam N10-008) helps develop a career in IT infrastructure covering troubleshooting, configuring, and managing networks.

CompTIA Network+ validates the technical skills needed to securely establish, maintain and troubleshoot the essential networks that businesses rely on.

Unlike other vendor-specific networking certifications, CompTIA Network+ prepares candidates to support networks on any platform. CompTIA Network+ is the only certification that covers the specific skills that network professionals need. Other certifications are so broad, they don't cover the hands-on skills and precise knowledge needed in today's networking environments.

CompTIA Network+ features flexible training options including self-paced learning, live online training, custom training and labs to advance the career development of IT professionals in network administration.
