I will plan to take VCP 5.0 exam. What is the best way to prepare the exam?
Welcome to the Community - The advice I always give is to use the VCP Blueprint as your study guide because it presents the topice that can be included on the exam - Use the class documentation at your starting point filling in the holes with the VMware documentation referenced in the Blueprint -
Start with covering the blueprint. Build a test lab of vSphere suite and spend some in practicing the one which you have read.
Just to want to point that you need to attend the authorized training course to be VCP-DCV certfied
To me, there's 3 things:
1. the blueprint - to plan
2. the documentation - to study
3. the software - to play
You will need to attend authorised vSphere training as part of the certification process.
Some good start points:

You can find some resource also here:
VCP5-DCV | vInfrastructure Blog
but fist start from the certification page to check the requirements.
