J2EE Architect Certifcations sample questions
These are example of actual questions from the J2EE Architect certification test as best as I could remember them a couple of hours after taking the exam. I don’t have the exact multiple choice options in most cases, but the following questions should give you some idea how well you need to know at least some of the topic areas. The questions were easier than I had expected for the most part. The questions mostly tested your understanding of terms and concepts at a high level.
There is another test with 22 questions J2EE Architect Certification Practice Test which is similar to what you take in Part 1
The test will tell you how many correct answers there are for each question, and the software will let you know if provide more or less answers than the expected amount. The structure of the multiple choice test was helpful and made the test a little easier. There are 48 questions on the test and you have 90 minutes to complete the test. I finished with 20 minutes to spare and spent the extra time going over my answers. The software allows you to skip questions and also mark questions. After answering question 48, you get a display showing the questions that you have skipped, are incomplete because you didn’t provide as many answers as expected, as well as questions that you have marked. You can then revisit any of the questions. The software also always displays the amount of time you have remaining.
| Question | Comments/My Answer |
| Where is JNDI used in JSM? | It is used to look up several of the key objects in the JSM model. |
| What pattern does JDBC ResultSet implement? | Iterator |
| What aspect of firewalls affects the ability of various protocols to get through. Three of the possible answers were: port filtering, address filtering and address translation. | Not sure what is the right answer. Let me know if you have an answer and please give me a reference where I can find documentation that supports the answer. |
| What 2 services does EJBs provide? Three of the 4 options were: life cycle management, transaction services, remote method invocation | I believe the answer is life-cycle management and transaction services. EJBs do provide remote access, but it isn’t considered a considered a service. |
| Where would encryption be necessary in a scenario where a buyer and a seller used a web browser to buy and sell items on the web and credit card info was verified by a separate system. Items being sold are stored in a database. Select 2 of the three possible places: between buyer and server, seller and server, server and credit card authority. | Where ever credit card info is passed which is from buyer to system/database and between system and credit card authority. I don’t recall anything more specific than this being asked about encryption. Some questions that I can’t remember in detail required knowledge of JDK security model and I believe it touched on the differences between JDK 1.1 and JDK 1.2 security models. |
| What aspects of a system vary by locale? | String formats, dates, order that things are sorted, how currency is displayed. |
| What kind of operations should be performed in ejbPassivate and ejbActivate on a stateful EJB? | Free/restore connections to resources. |
| One question tested my understanding of EJB transaction attributes (not supported, supported, required, required new, etc.) | |
| One question required understanding of a Handle object relative to EJBs. |
