1Z0-510 Online Practice Questions and Answers

Correct Answer: CD

Scenarios, slots, and workflows are not managed through the ATG Business Control Center (BCC). To create and edit these items, use the ATG Control Center (ACC)

D: You can create slot components in two ways:

By manually creating a .properties file

Through the slot wizard in the ACC.

Note ACC: ATG Control Center.

Note BCC: The ATG Business Control Center is a browser-based interface that you use to create and edit many of the elements required to set up and maintain an ATG-based Web site

Correct Answer: A

Correct Answer: C

dsp:importbean

Imports a servlet bean or JavaBean component into a JSP.

Attributes

*

bean

Set to the fully-qualified Nucleus path and name of the servlet bean to import.

*

var

Names an EL variable that enables access to other page tags. When you use var, you can set its scope attribute to page, request, session, or application. The default scope is page.

If var is omitted, the shorthand name for the component is used.

*

scope

By default, the named variable is set to page scope, which makes it accessible to any EL-enabled resources on the same page. The scope attribute lets you define a larger scope for variable, by setting it to request, session, or application.

Correct Answer: A

The design of the OrderFulfiller and the HardgoodFulfiller uses the ClientLockManager to prevent one component from processing messages for two different orders at the same time.

Correct Answer: AB

The Personalization module provides features that are specifically designed to support Web site personalization, which is the process of displaying different content to each site visitor depending on his or her preferences and requirements.

Note: In order to create and maintain a personalized Web site, you must make a series of decisions about your site visitors and the content you want to show them; for example, how do you want to segment your site visitors? Do you want to show specific content to different age groups? Do you plan to use a site visitor's income bracket to determine what to show her? And what content, specifically, do you want to show to each group of people?

Once you have planned your approach to the relationship between site visitors and content, you use the ATG Control Center to do the following:

Create profile groups Group similar content items together Match content groups to profile groups Determine the visitor behavior that you will track and use to update profiles

Correct Answer: B

The multi-column-name attribute ensures that the ordering of the multi-values are maintained. The column specified by the multi-column-name attribute is used for multi-valued properties of data type array, map, and list and is not used for sets (which are unordered). For map type properties, the values in the column specifiedy by the multi-column-name attribute must be a string. For list or array type properties, these values should be an integer or numeric type, and must be sequential.

Correct Answer: BCD

Nucleus: Organizing JavaBean Components

Nucleus is Oracle ATG Web Commerce's component model for building applications from JavaBeans.

Nucleus lets you assemble applications through simple configuration files that specify what components are used by the application, what parameters are used to initialize those components, and how those components hook up to each other.

Nucleus by itself provides no application-specific functions. The JavaBean components implement all of an application's functionality. Nucleus is the mechanism that gives those components a place to live, and a way for those components to

find each other.

Note: Event Sources

Your class can be a source for JavaBeans events by following the patterns outlined in the JavaBeans specifications (see Events and Event Listeners in the Core ATG Services chapter). If your class fires events, Nucleus properties files can

be used to configure the listeners for those events.

D: However, these classes should implement certain interfaces that give components access to a number of Nucleus capabilities, such as automatic creation, configuration, and notifications.

The easiest way to implement these interfaces is to subclass atg.nucleus.GenericService, which implements all interfaces described in the following sections. However, your class might already extend some other class, thereby preventing you from extending GenericService. In this case, your class must implement the necessary interfaces.

Note: Your class does not need to implement all interfaces that GenericService implements, only the ones with the functionality required.

E: Any Java object with an empty constructor can act as a component in Nucleus.

Note: Java has several design patterns Singleton Pattern being the most commonly used. Java Singleton pattern belongs to the family of design patterns, that govern the instantiation process. This design pattern proposes that at any time there can only be one instance of a singleton (object) created by the JVM.

The class's default constructor is made private, which prevents the direct instantiation of the object by others (Other Classes). A static modifier is applied to the instance method that returns the object as it then makes this method a class level method that can be accessed without creating an object.

Correct Answer: B

public class Qualifier extends GenericService A Helper class for discount calculators. Calculators call their helper method in this class to determine to which items they should apply their discount. As a side effect, the Qualifier also keeps track of which items acted as qualifiers for the input promotion, if applicable, and marks their priceInfos as appropriate.

Correct Answer: B

The QueryOptions properties let you limit the size of the result set, direct how the result set should be sorted, and precache specified properties.

You can use the atg.repository.QueryOptions class to specify ways that a query can be modified. You can set the QueryOptions properties, and pass the QueryOptions bean to the following executeQuery method:

RepositoryItem[] executeQuery(Query pQuery, QueryOptions pQueryOptions);

Correct Answer: B

ATG Commerce provides the following configured instances of the state classes, which are located in us at /atg/commerce/states/:

OrderStates: indicates the states of an Order.

For the display names of states:

ORDER.INCOMPLETE=INCOMPLETE ORDER.SUBMITTED=SUBMITTED

For the descriptions of states: ORDERDESC.INCOMPLETE=The order is incomplete ORDERDESC.SUBMITTED=The order has been submitted to Fulfillment
