Took Cisco 100-101 exam few hours ago with 1 month of hard studying and went for it!! Scored 970!!! Main knowledge points of the exam:
1. Operation of IP Data Networks (Not hard, easy to answer)
2. LAN Switching Technologies (The most difficult part of the full exam!!!)
3. IP addressing IPv4 and IPv6 (Not hard, easy to answer)
4. IP Routing Technologies
5. IP Services
6. Network Device Security
P.S. No ACL or NAT sims. I used 238q 100-101 exam dumps from passleader.com.
