Question 1

Which of the following statements defines an "aspect"? (select one)
A) An encapsulation of advice combined with a pointcut.
B) A point in the execution of a program such as a method call or field assignment
C) An expression that selects one or more join points
D) Code to be executed at a join point that has been selected by a Pointcut

Accepted Answer

An aspect is a modular unit of cross-cutting implementation, which includes both advice (code to be executed) and pointcuts (expressions that select join points).

Question 2

Consider the following bean definition <bean id="clientService" class="com.springsource.service.ClientServiceImpl" /> Using Spring AOP, you have declared a Pointcut targeting all methods inside the clientService bean. ClientServiceImpl implements 3 different interfaces. Which interfaces will the proxy class implement? (Select one)
A) All interfaces
B) The proxy class does not implement any interface
C) A Spring bean should never implement any interface

Accepted Answer

The proxy class will implement all interfaces that the target class (ClientServiceImpl) implements. This is a feature of Spring AOP when using JDK dynamic proxies.

Question 3

Which statement concerning Aspect Oriented Programming (AOP) is true (Select one)
A) AOP modularizes cross-cutting concerns
B) Spring AOP implements aspects using the Proxy pattern
C) Three of the advice types are "before", "after" and "around"
D) All of the above

Accepted Answer

AOP is designed to modularize cross-cutting concerns, Spring AOP uses the Proxy pattern for implementing aspects, and "before", "after", and "around" are indeed types of advice in AOP.

Question 4

Which of these is NOT a characteristic of Spring JDBC? (Select one)
A) Can be configured exclusively using annotations
B) Provides a callback approach when greater developer control is needed
C) Connections are acquired and released from the DataSource automatically
D) Translation of root cause checked exceptions to Spring DataAccessExceptions

A) It abstracts the differences between local and JTA transactions
B) It simplifies migration to distributed transactions
C) The use of JTA transactions is a requirement
D) Both declarative and programmatic transaction management is supported

Accepted Answer

Spring Transaction Management does not require the use of JTA transactions; it supports both local and JTA transactions, allowing flexibility in transaction management.

Question 8

Identify the correct statement about the following pointcut expression: execution(@javax.annotation.security.RolesAllowed * rewards.restaurant.*.*(..)) (Select one)
A) The return type of the target method is RolesAllowed
B) All method parameters should be annotated with @RolesAllowed
C) The target method may have one argument
D) All of the above

Accepted Answer

The pointcut expression specifies that the target method is within the rewards.restaurant package and can have any return type and any number of arguments, including one. The @RolesAllowed annotation is not related to the return type or method parameters in this context.

Question 9

Identify the correct statement(s) about the following pointcut expression: execution(* rewards.restaurant.*Service.find(..))
A) The target's type should end with "Service"
B) The target method name could be "findRestaurantById"
C) The target method should have one argument only
D) The target method may have several arguments

Accepted Answer

The pointcut expression specifies that the target's type should end with "Service" and the method name should start with "find" and can have any number of arguments, including zero or more.

Question 10

To register for a bean destruction callback, one can (Select one) A) Decorate the destroy method with @PreDestroy B) Decorate the destroy method with @PreDestroy and add a xml declaration C) Set the bean instance in a "prototype" scope D) Set the lazy-init attribute within the tag

Accepted Answer

Decorating the destroy method with @PreDestroy and adding a <context:annotation-config /> xml declaration allows the bean destruction callback to be registered.

Question 11

Which of the following statements is NOT true about Spring AOP? (Select one)
A) "private" methods cannot be advised, but all other method visibilities can be
B) Proxy classes are created at startup time by default
C) The "After Throwing" advice type executes after the join point, but executes only if the advised method threw an exception
D) The "After" advice type is invoked regardless of whether a method successfully returned or an exception is thrown

Accepted Answer

The answer of Which of the following statements is NOT...

Question 12

Which of the following statements best describes the After Throwing advice type? (select one)
A) The advice is executed after a method invocation throws an exception
B) Custom processing can be performed before a join point executes
C) The advice is invoked only if the method returns successfully
D) The advice is designed to allow exceptions thrown from a join point to be caught and prevented from propagating up the stack

Accepted Answer

After Throwing advice is executed after a method invocation throws an exception, allowing for handling or logging of the exception.

Question 13

Which of the following statements about Pointcut expressions is true? (Select one)
A) A Pointcut can be defined either within annotations in Java code or within XML configuration
B) A pointcut expression can include operators such as the following: && (and),|| (or), ! (not)
C) A Pointcut expression can be used to select join points which have been annotated with a specific annotation
D) All of the above is true

Accepted Answer

All the statements about Pointcut expressions are true: they can be defined in annotations or XML, use logical operators, and select join points with specific annotations.

Question 14

Identify the correct statement(s) regarding the <aop:aspectj-autoproxy /> tag (Select one or multiple answers)
A) Can only be used with AspectJ (as opposed to Spring AOP)
B) Enables the detection of @Aspect annotated classes
C) Allows to define a list of names to include so Spring is not going to scan all the beans at startup

Accepted Answer

The <aop:aspectj-autoproxy /> tag enables the detection of @Aspect annotated classes and allows to define a list of names to include so Spring is not going to scan all the beans at startup.

Question 15

Which of the following statements defines a "pointcut"? (select one)
A) A point in the execution of a program such as a method call or field assignment
B) A module that encapsulates advices
C) An expression that selects one or more join points
D) None of the above

Accepted Answer

A pointcut is an expression that selects one or more join points, which are specific points in the execution of a program where an aspect can be applied.

Question 16

Which of the following statements is NOT true about advice types and exception handling?  (select one)
A) If a Before advice method throws an exception, the target method will not be called
B) An Around advice type can swallow, or halt the propagation of, an exception thrown by the target method.
C) An AfterReturning advice type can swallow, or halt the propagation of, an exception thrown by the target method.

Accepted Answer

An AfterReturning advice type is executed only if the target method completes normally, so it cannot handle or swallow exceptions thrown by the target method.

Question 17

Identify the correct statement(s) regarding the following pointcut: execution(@com.springsource.MyCustomAnnotation void *(..))
A) Spring does not support annotations inside its pointcut expression language
B) This will select join points representing void methods that are annotated by @com.springsource.MyCustomAnnotation
C) This will select join points representing methods that may have a public, protected or default visibility
D) This pointcut will in no situation ever be able to select any join points

Accepted Answer

This pointcut expression is designed to select join points for void methods that are specifically annotated with @com.springsource.MyCustomAnnotation.

Question 18

Which statement best describes the advantage of using AfterReturning advice, rather than simply using after advice? (Select one)
A) If an exception is thrown in the join point, it is allowed to propagate, which is not the case with After advice
B) AfterReturning advice is invoked if an exception is thrown, which is not the case with After advice
C) After advice can only be applied to methods which are declared as void
D) AfterReturning advice is only invoked if the method returns successfully, allowing you to limit advice to only those scenarios

Accepted Answer

AfterReturning advice is specifically designed to be invoked only when a method completes successfully, allowing you to apply advice only in those scenarios, unlike After advice which runs regardless of the method's outcome.
