SpringSource SpringSource Certification Program CORESPRINGV3.2 Questions & Answers

• Question 31:

  Consider that all Spring beans have been declared within a package called "com.springsource.service". To enable component scanning one must do the following:

  A. Nothing (component scanning is enabled by default)

  B. Add to your XML configuration

  C. Add to your XML configuration

  D. Remove all other bean definitions from the XML configuration

  Correct Answer: C

• Question 32:

  public class ClientServiceImpl implements ClientService {

  @Transactional(propagation=Propagation.REQUIRED)

  public void update1() {

  update2();

  }

  @Transactional(propagation=Propagation.REQUIRES_NEW)

  public void update2() { // ... }

  }

  You are using transactions with Spring AOP. What is happening when the update1 method is called?

  (Select one)

  A. There is only one transaction because the call to update2() is internal (it does not go through the proxy)

  B. There is only one transaction because REQUIRES_NEW runs into the active transaction if one already exists

  C. There are 2 transactions because REQUIRES_NEW always runs in a new transaction

  Correct Answer: A

• Question 33:

  Which of the following is the correct mechanism for using programmatic transactions in Spring? (Select one)

  A. Use of the @Transactional annotation on each method which should be transactional

  B. Use of the @Transactional annotation on the Class of methods which should all be transactional

  C. Configuration in an XML configuration file using the Spring "tx" namespace

  D. Use of the Spring TransactionTemplate

  Correct Answer: D

• Question 34:

  If the propagation behavior is Propagation.REQUIRES_NEW, choose the statement which describes the propagation behavior (select one)

  A. Runs in a nested transaction if an active transaction exists. If an active transaction does not exist, the transaction behaves as if Propagation.REQUIRED is set

  B. Supports a transaction if one already exists. Throws an exception if an active transaction does not exist.

  C. Always starts a new transaction. If an active transaction already exists, it is suspended

  D. Always executes without a transaction even if an active transaction exists. Throws an exeception if an active transaction exists.

  Correct Answer: C

• Question 35:

  If the propagation behavior is Propagation.REQUIRED, choose the statement which describes the propagation behavior (select one)

  A. Executes in a transaction if one already exists. If there is no transaction, it executes without a transaction context.

  B. Executes in a transaction if one already exists. Throws an exception if there is no active transaction.

  C. Executes in a nested transaction if an active transaction exists. If there is no transaction, it starts a new one.

  D. Executes in a transaction if one already exists. If there is no transaction, it starts a new one.
