Examen final CCNA 3 is simply the Spanish way of saying you are taking a final exam in the CCNA 3 subjects or topics you covered as part of your accreditation to become a CCNA Specialist. CCNA 3 stands for the third module in the four-module CCNA series.
If you have successfully hurdled all the four modules of the CCNA series, you qualify for the CCNA 640-801 accreditation. However, the difference between English exams and the Examen final is that you take the Examen final in Spanish, since you probably studied all four modules of the CCNA series in Spanish as well.
And since you studied and trained using Spanish, most likely you will also be practicing what you learned using Spanish to communicate your knowledge to others (unless you have a degree of proficiency in English as well.)
The whole CCNA four-module series can actually be subdivided into three main categories: Networking Basics, Intermediate Routing, and WAN Technologies.
Networking Basics does cover the OSI Model, the TCP/IP Model, and Structured Cabling routing basics. It also covers Static Routing, the RIP-IGRP dynamic routing, setting of Cisco routers, and listing of Access Switching Basics.
Intermediate Routing is divided into the Setup Switches Catalyst category, and then the VLANS category (which involves OSPF & EIGRP routing).
Studies in WAN Technologies cover PPP-HDLC, Frame-Relay, ISDN, and lines point to point.
Career certificates in Spanish need to be issued jointly by the Local Academy and the Academy Regional in cooperation with Cisco Systems which owns the CCNA series standards.
