Note: Even though the certification exam is of multiple choices, it is very confusing to choose the right answer. So prepare well for attending the exam.

1. Basic services: 

EC2, VPC, RDS, and S3 are the basic amazon services. You should get hands on experience with these services. If you have knowledge about the services, you can start preparing for the certification by reading the FAQ's of these services.

2. Other services: 

You can expect many questions from the basic services I explained in step 1. Once you have a good understanding about the basic services, you can start learning the fundamentals of services mentioned below.

You don't have to learn all the AWS CLI command and API references. AWS does not want to test you with API's and CLI's.

VPC (virtual private cloud) is one of the important services that you should have good knowledge of for passing AWS certification. Following are the VPC service options you should learn about.

You should have good knowledge about s3, its policies and associated its associated services like CloudFront. Glacier is another storage service you should have knowledge of.
