How similar are the labs on the ccna exam compared to the CicsoKits Lab book?

in CCNA & CCENT
With out giving any specifics, how similar are the labs on the ccna exam compared to the CicsoKits Lab book?
If I can do the labs in that book basically just by looking at the diagram, should I be able to do most of the labs on the CCNA test?
TIA
