CCNA v2.0: what changed, and whether to sit v1.1 first
Six domains become five, troubleshooting returns after five years, and AI joins the blueprint. The real weights read from Cisco's own exam topics, side by side with v1.1.

The complete v1.1 and v2.0 blueprints, topic by topic, tagged with the verb Cisco used - so you know what to memorise and what to lab.
CCNA exam cost, format and passing score
$300, 120 minutes, about 100-120 questions (Cisco does not publish a count or a passing score), no going back, 5-day retakes.

Advanced labs: real CLI labs
CCNA v2.0 brings the troubleshoot verb back on 3 February 2027, and it is how the job starts on day one. These are 9 live networks, each broken on purpose: you find the fault from the console with real IOS show commands, fix it, and the network grades the repair. One lab is free with the CCNA code.
WAN troubleshootingFree lab
Branch Office Connectivity Failure
A branch PC has lost access to the head-office server. Work through the path - the access switch, the branch router and the head-office router - find what is wrong, and fix it so PC1 reaches Server1 again.
OSPF
Three Sites on OSPF
Head office, branch and warehouse run a single OSPF area over a triangle of links. One site has dropped out of the routing domain. Find out why the adjacency will not form and bring the site back.
EtherChannel
Bundle the Access Uplink
Two cables run between the access switch and the distribution switch, and they were meant to work as one 2 Gbps link. The bundle has not formed, so spanning tree is blocking half the capacity. Get the channel up.
CCNA troubleshooting labs
Every lab, the blueprint topic it drills in v1.1 and v2.0, and real console output from a broken EtherChannel before and after the fix.
