• Question 71:

  Your site supports configurable commerce Items and you want to enable price list based pricing. How would you configure the /atg/commerce/pricing/ItemPricingEngine?

  A. preCalculators=\calculators/ItemListPriceCalculator,\calculators/ConfigurableItemPriceCalculator

  B. preCalculators=\calculators/ItemPriceListCalculator,\calculators/ConfigurableItemPriceListCalculators

  C. preCalculators=\calculators/ItemPriceListCalculator

  D. preCalculators=\atg.commerce/pricing/calculators/ItemListPricecalculator

  Correct Answer: D

  Price List Calculators

  An ItemPriceCalculator class maintains all the functionality common to all the pricing schemes.

  Three sub-calculators correspond to the three different pricing schemes. The three different schemes are calculating the list price of an item, calculating the price of an item using bulk pricing, and calculating the price of an item using tiered

  pricing.

  *

  ItemListPriceCalculator: Calls the getPrice method from the PriceListManager to retrieve the list price of the CommerceItem.

  *

  ItemBulkPriceCalculator

  *

  ItemTierPriceCalculator Note:

  *

  The ItemListPriceCalculator is a calculator which determines the list price of an item and sets the itemPriceInfo to be that amount. The pricing scheme for that item is list pricing.

• Question 72:

  Which of the following two outcomes are achieved by the following snippet of code?

  A. Imports shipping Conf into page Context so you can exclude the full path and use the ShippingConf as short hand

  B. Imports Shipping Conf into page Context so you can exclude the full path and use the shipConf as short hand

  C. Makes the Shipping Conf available to the EL through the name ShippingConf

  D. Imports the ShippingConf to the page and is required to or reference it on the page

  E. Allows access to the DSP element through JavaScript or AJAX library

  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.

• Question 73:

  How is the result set cached when a query returns repository items whose item descriptors enable both item caching and query caching?

  A. The query cache stores the repository IDs indexed by the given query and the item cache holds the corresponding repository items indexed by the repository IDs.

  B. The query cache stores both the repository IDs and the- repository items. The item cache is ignored.

  C. The item cache stores the both the repository IDs and the repository items. The query cache is ignored.

  D. Item descriptors can enable either the item cache or the query cache but not both.

  Correct Answer: A

  Difference between Item Cache and Query cache

  For each item descriptor, an SQL repository maintains two caches:

  *

  Item caches

  *

  Query caches

  Item caches hold the values of repository items, indexed by repository IDs. Item caching can be explicitly enabled for each item descriptor.

  *

  Query caches hold the repository IDs of items that match given queries. When a query returns repository items whose item descriptor enables query caching, the result set is cached as follows:

  / The query cache stores the repository IDs.

  / The item cache stores the corresponding repository items.

• Question 74:

  What would be the Ground and Expedited shipping prices for an order of a single item with a price of 15.99 and having a weight of 42 with this configuration (assume no active shipping promotions)?

  /atg/commerce/pricing/shippingPricingEngine.Properties:

  PreCalculators =\

  Calculators/GroundshippingCalculator,\

  Calculator/ExpiditedShippingCalculator

  postCalculators=calculators/MypostCalculator

  /atg/commerce/pricing/calculators/GrowthShippingCalculators.proprties:

  $class=atg.commerce.pricing.priceRangeShippingCalculator ignoreShippingMethod=false

  shippingmethod=Ground

  ranges =\

  00.00:15.99:4.50,\

  16.00:30.99:6.00,\

  31.00:40.99:7.25,\

  41.00:MAX_VALUE:10.00

  /atg/commerce/pricing/calculators/ExpeditedShippingCalculators.proprties:

  $class=atg.commerce.pricing.priceRangeShippingCalculator ignoreShippingMethod=false

  shippingmethod=Expedited

  ranges =\

  00.00:15.99:4.50,\

  16.00:30.99:6.00,\

  31.00:40.99:7.25,\

  41.00:MAX_VALUE:10.00

  /atg/commerce/pricing/calculators/MyPostCalculators.properties:

  $class=atg.commerce.pricing.FixedPriceShippingCalculator AddAmount=true

  ignoreShippingMethod=true

  shippingmethod=SpecialSurcharge

  amount=4.99

  A. Ground: 4.50, Expedited: 10.00

  B. Ground: 10.00, Expedited: 10.00

  C. Ground: 4.99, Expedited: 4.99

  D. Ground: 9.49, Expedited: 14.99

  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.

• Question 75:

  Assume that a versioned repository item in your application is not changed on the store serves hut is only changed on the CA Server and published to the store server.

  Which caching mechanism should you choose for it on the store server?

  A. any of the CA-aware caching modes such as locked, distributed, or hybrid

  B. Locked Caching

  C. Immutable Item Caching

  D. Simple Caching

  E. No caching is necessary. Database will cache the Items as they do not change on the server.

  Correct Answer: A

• Question 76:

  Identify the significance of using cascade="insert" from the snippet below:

  A. An item of type articles is created once a new user is created.

  B. If a user is deleted, all items in articles of that user are deleted.

  C. insert is ignored for properties that use the attribute component item-type.

  D. An article named favoriteArticles is created.

  Correct Answer: C

  The cascade="insert" attribute is ignored for properties that use component-item-type.

  Note: Cascade Insert

  If a repository item has a property with the item-type attribute and the cascade="insert" attribute set, on item creation:

  A new item of the type declared by the item-type attribute is also created.

  The property is set to point to the other item created.

  The cascade="insert" attribute is typically used with cascade="update" and cascade="delete" so management of this item is completely automatic. The item is created, added, updated, and deleted along with the parent item. The cascade="insert" attribute is ignored for properties that use component-item-type.

• Question 77:

  What do you need to do to disable ATG's Out-of-the-Box behavior of persisting order change?

  A. Set /atg/commerce/order/OrderTools.persistOrders = false

  B. Set/atg/commerce/order/OrderManager.persistOrders=false

  C. Set /atg/commerce/ShoppingCart.persistOrders = false

  D. ATG does not allow you to modify this behavior.

  Correct Answer: C

  Understanding the ShoppingCart Component The ShoppingCart component is responsible for storing and managing a customer's shopping carts. It maintains the customer's current shopping cart that is used during the purchase process, and it stores any other shopping carts that have been persisted by that customer. These shopping carts are represented as atg.commerce.order.Order objects in the ATG Commerce object model, and represented as order items in the Order Repository.

• Question 78:

  Identify the problem with the following targeter rule set:

  A. All rule sets need a "reject rule".

  B. All rule sets need a sorting directive.

  C. Rules cannot contain two accept directives.

  D. A rule set cannot reference repository items.

  Correct Answer: C

  A rule set contains one tag. The tag must have at least one and at most five child tags:

  one of ,, or tags must be present. The and tags are optional. Multiple , ,, , and tags are not allowed.

• Question 79:

  If you want to update the computedCatalogs and parentCatalog properties of a product, which service should you use?

  A. ProductUpdateService

  B. CatalogGeneratorService

  C. AncestorGeneratorService

  D. ComputedCatalogService

  Correct Answer: C

  The AncestorGeneratorService component generates ancestor categories for the product and category item types, and stores the names of these ancestor categories in the ancestorCategories property of each product and category.

  The AncestorGeneratorService updates the following property values for each of the catalog item types. This service must be executed after making catalog updates in order for catalog navigation and search to work correctly.
