In the United States, the requirements are the same for all types of veterinarians: you must have either a DVM or VMD degree.
First you train to be regular veterinarian. Then you specialize. For some species, there is no formal training. You have to find a clinic that work with those animals, get employed there and learn from others.
In the United States all types of veterinarians receive the same training - four years of vet school. However, an exotic animal veterinarian ideally would also complete externships and possibly an internship to focus on the non-traditional species they are interested in.

Is it easy being a vet. the reason i want to be a vet is because I really love animals. i was wondering if you could help me on what i need to know?
Depending on the animals you are wanting to train you may be able to learn the skills on the job. You will need some advanced degrees or certification if you want to train some of the more exotic animals.
You start the same way every veterinarian does - by completing the pre-requisite courses in undergraduate college, then completing the curriculum at an accredited school of veterinary medicine. In some cases you will have enough knowledge of the non-traditional species you are interested in to start working immediately as an exotic animal veterinarian; in other cases, you may want to pursue an internship then a residency to increase your knowledge base before starting to work as an exotic animal veterinarian.

Usually none - there are relatively few promotions within veterinary medicine outside of buying into a clinic and shifting from being just a veterinarian to a veterinarian/clinic owner. However, you can go for board certification, which usually requires a three-year minimum residency for training, or you can go back to school for supplemental degrees like an MBA.
