he Certified Wireless Network Administrator (CWNA) certification, offered by the Certified Wireless Network Professional (CWNP), is designed for IT professionals involved in the design, implementation, and management of wireless networks. CWNA serves as a foundational certification within the CWNP program, covering essential wireless networking concepts and technologies. Here’s an overview of the CWNA certification:
Key Details:
- Certification Path:
- CWNA is an entry-level certification within the CWNP certification program. It is a prerequisite for advanced CWNP certifications like CWSP (Certified Wireless Security Professional) and CWAP (Certified Wireless Analysis Professional).
- Vendor-Neutral Focus:
- CWNA is vendor-neutral, meaning it is not tied to a specific wireless equipment manufacturer. This makes the certification applicable across various wireless networking environments.
- Prerequisites:
- There are no formal prerequisites for the CWNA certification. However, it is recommended for individuals to have a basic understanding of networking concepts.
