Indeed, there are two certified courses included in this programme:
1. 100-105: ICND1
2. 200-205: ICND2
These 2 certificates together will give you the full CCNA 200-125 Certification.
Finally, a CCNA certification is valid for three years, after which time it will then be necessary for you to re-certify. At this point or sooner, you may choose to progress to the next tier of Cisco certification, the most popular being CCNP.
