1Z0-510 Online Practice Questions and Answers

Correct Answer: D

For Ground the calculation is 4.50 (Price range is used) + 4.99 (the post calculator always gives this result) -> 9.49

For Expedited the calculation is 10.00 (Weight range is used) + 4.99 (the post calculator always gives this result) -> 14.99

Note 1: A ShippingPricingEngine implementation which computes the shipping price for an order. It accomplishes this task by invoking a series of ShippingPricingCalculators which incrementally compute the tax price:

The first step is to allow the preCalculators to manipulate the price. They are invoked in the order in which they appear in the preCalculators list.

The second step is to extract the calculators from any input PricingModels, and invoke them in the order in which they appear in the pPricingModels list.

The last step is to invoke the postCalculators in the order in which they appear in the postCalculators list.

Note 2: The ShippingPricingEngine is a structural component that does not actually calculate shipping prices itself. The actual price calculations are performed by the Pricing Calculator components that are configured as the preCalculators

and postCalculators properties of the ShippingPricingEngine.

Correct Answer: C

Flow of control defines which components have privileges to edit different parts of the order. The basic premise is that once a component has control over a part of the order, only this component should edit this part of the order.

ATG Commerce does not verify that a component has the privileges to edit a specific part of an order. ATG Commerce does not perform this verification because if the system is distributed, orders might be modified with a different system.

Correct Answer: B

In order to remove specific markers from an active user profile, create a scenario that uses the Remove markers from profile action and specify the key used by the markers you want to remove. You can provide additional information such as a value or data value: markers that have the values for the properties you provide will be removed from the active user profile. Refernence: ATG Personalization Programming Guide , Specific Profile Markers From a Profile

Note: Removing Profile Markers It's a good idea to set up a mechanism that removes profile markers when they are no longer relevant to your application. You may use markers to monitor some user behavior, but once you've gathered the data you need, flush markers from the profiles in one of the ways described here.

In general, you remove markers from a given profile either by removing specific markers or all of them at once.

Correct Answer: A

User profiles (and therefore logins) are always shared across all sites in the application.

Note: In the simplest case, these sites may share only user profiles, so a customer registered on one site is also registered on the other. In more complex implementations, the sites may share shopping carts, so a customer can include items from both sites in a single order. The bargain-brand site might also include upsell recommendations for (and links to) items on the luxury brand site, or the sites might share gift lists.

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: ABE

Subclassing ATG Form Handlers

Oracle ATG Web Commerce form handler classes all implement the interface atg.droplet.DropletFormHandler. Three form handler base classes implement this interface:

*

atg.droplet.EmptyFormHandler

*

atg.droplet.GenericFormHandler

*

atg.droplet.TransactionalFormHandler

You can create a form handler by extending one of these classes or any of their subclasses. er:

Correct Answer: C

atg.commerce.promotion, Class PromotionImportExport

This is the main class for the Promotions Import Export API. It enables integrators to import and export promotions. To import promotions the call sequence is, startImportExportSession, importPromotion (once for each promotion to import)

and endImportExportSession. To do an export the call is either exportPromotionsById or exportPromotionsByRQLQuery.

Note: If Oracle ATG Web Commerce is not your usual tool for creating and maintaining promotions, you will need to import promotions you create in your external system into Commerce for pricing purposes.

Commerce includes an API that allows you to build custom code for this purpose.

If you are using promotions templates, importing promotions is as simple as specifying which template to use and the placeholder values. If you are not using templates, you must first build the PMDL for your promotions.

Note 2: The promotions import/export API relies mainly on the following two components:

*

/atg/commerce/promotion/PromotionImportExport--The main component used for importing and exporting promotions

*

/atg/epub/PublishingWorkflowAutomator--Used automatically when you import promotions into a versioned repository; you should never need to call this component yourself

Correct Answer: BCD

Note B2C: Business-To-Consumer. A transaction that occurs between a company and a consumer, as opposed to a transaction between companies (called B2B). The term may also describe a company that provides goods or services for consumers.

Correct Answer: A

To change the secret key that the Personalization module uses to hash the user ID cookie, edit the following property of/atg/userprofiling/CookieManager:

Note: cookieHashKeySets the hash key to use for hashing user ID cookies. If this property is set, its value is used for the hash key rather than a value generated by the HashInitializer component. Sets a secret key that the Personalization

module uses to hash the user ID cookie. This behavior makes user cookies more secure and prevents users from using another user's profile by changing their cookie. Invalid profile cookies are ignored. You may want to change this from the

default value, so that your site's cookies will be hashed with a different key from that used by other sites that run ATG products.

Correct Answer: D

first is a page parameter. We use getPageParameter to access it. last is a bean parameter. We use getParameter to access it.

Note: dsp:param

Identifies a servlet bean input parameter; or defines a page parameter.

param-value />

attributes

name (servlet bean)

Identifies an input parameter that is defined for the current servlet bean. For information on input parameters for specific servlet beans, see Appendix B, ATG Servlet Beans.

name (page parameter)

Defines a page parameter that is accessible to the current JSP and embedded child pages.
