In transactional management, what is ACID?

Accurate, Controlled, Independent, Done

Atomicity, Consistency, Isolation, Durability

Accurate, Controlled, Isolation, Durability

Atomicity, Consistency, Independent, Done

Correct! Wrong!

Explanation:
ACID (Atomicity, Consistency, Isolation, and Durability) refers to a collection of features in database systems that ensure database transactions are processed reliably. ACID is particularly concerned with how a database recovers from any failures that may occur during transaction processing.

What exactly is the Spring MVC framework?

Spring MVC framework is used for Transaction management for WEb Applications

Spring MVC framework is used for AOP for Web Applications

The Spring web MVC framework provides model-view-controller architecture and ready components that can be used to develop flexible and loosely coupled web applications.

Spring MVC framework is Model-Value-Class architecture and used to bind model data with values

Correct! Wrong!

Explanation:
Model-view-controller architecture and ready components are provided by the Spring web MVC framework, which may be used to create flexible and loosely linked web applications. The MVC pattern separates the various pieces of an application (input logic, business logic, and user interface logic) while maintaining a loose coupling between them.

What exactly is spring?

Spring is a proprietary framework

Spring is an open source development framework for enterprise Java.

Spring is a development framework for PHP based applications

Spring is a development framework for .NET applications

Correct! Wrong!

Explanation:
Spring is a Java development framework that is free and open source.

If a bean is scoped to an HTTP session, it is considered scoped.

request

prototype

global-session

session

Correct! Wrong!

Explanation:
The scope of a bean that is scoped to an HTTP session is session.

What exactly is a target object?

This is used to inject values in the object

This is not invoked during program execution by the Spring AOP framework

The object being advised by one or more aspects, this object will always be a proxy object, also referred to as the advised object.

A represents an object in your application where you can plug-in AOP aspect

Correct! Wrong!

Explanation:
The target object is the (Java or Spring) component to which you wish to add new behavior, which is frequently a cross-cutting issue, i.e. behavior that will be applied to multiple classes throughout your code base. An aspect is a class in which you implement that cross-cutting concern as well as define where and how it should be applied.

Which version of the spring framework introduces thread scoped beans?

2.0

3.0

4.0

1.0

Correct! Wrong!

Explanation:
The thread scoped bean was first introduced in the spring framework 3.0 version.

What is autowriting autodetect mode?

Auto-writing based on the name of the property. Spring tries to match and wire its properties to the beans in the configuration file that have the same name.

ByType is similar to type, except that type applies to constructor arguments. A fatal error is raised if there isn't exactly one bean of the constructor argument type in the container.

autowriting based on the type of property. If a property's type matches exactly one of the beans named in the configuration file, Spring will try to match and wire it.

Spring tries to wire using autowire by constructor first, then autowire by byType if that doesn't work.

Correct! Wrong!

Explanation:
Spring tries to wire using autowire by constructor first in autodetect mode of autowiring, and if it doesn't succeed, it tries to autowire using byType.

What exactly is an aspect?

Aspect represents properties of spring based application

Aspect is a way to do the dependency injection

A module which has a set of APIs providing cross-cutting requirements

Aspect is used to log information of application

Correct! Wrong!

Explanation:
Weaving: The complete process of intercepting the execution of a method and applying an aspect to it. Aspect: A mixture of the Point Cut and the Advice Join Point: This refers to when a method's execution has been intercepted and the aspect is in use

What is the case with collection configuration components using the props tag?

This can be used to inject a collection of name-value pairs where the name and value are both Strings.

This helps in writing a list of values, allowing duplicates

This helps in writing a list of values but without any duplicates

This can be used to inject a collection of name-value pairs where name and value can be any type

Correct! Wrong!

Explanation:
The props tag is used to inject a list of name-value pairs, with name and value both being Strings.
