JAVA EE 7 APPLICATION DEVELOPER: 1Z0-900

Java EE 7 Application Developer exam, also known as as 1Z0-900 is of the most in-demand certifications among Java and Java EE developers who aim to become Oracle Certified Professional, Java EE 7 Application Developer. It's in-demand and well recognized among companies and employers all around the world, but at the same time it's one of the toughest exams to crack given the vast amount of topics to cover from Servlet, JSP, REST, to CDI and EJB etc. While passing score is 66%, lower than Spring Professional Certification of 76% but question are tougher and you usually require long preparation time like 4 to 6 months.
Because of that, many experienced Java developers who have worked on the Java EE, Servlet and JSP for years struggle to pass this exam. The key to passing the exam is not only to prepare well but also to build the speed and accuracy to solve enough questions correctly to score at least 66% in a limited time and that's where this Practice test will help you.
This course contains 210 unique and high-quality practice questions to prepare for Java EE 7 Application Developer 1Z0-900 certification exam.  You can not only use them to build the speed and accuracy required but also get a sense of what kind of questions you can get in exam. They are also great to revise essential Java EE concepts.
