Which one is easy to complete, CCNP Route or CCNP Switch?

Both CCNP Route and Switch are easy. However CCNP Routing takes a little more time than CCNP Switching. If you are planning to take your CCNP Course Training or want to prepare for the Certification, i suggest you to take Route first. Once you are done with your CCNP Route Training and preparation, you can mix the Routing tasks in your switch preparation.

When you are doing Switching practicals, add some Routers in the scenario/diagram, add some Routing Tasks to it to make it a bigger practical. This is how you will be able to perform better and complex practicals. It gives you one more benefit that you will be able to revise all CCNP Routing technologies/protocols while preparing for Switching.
