Oracle Oracle Certifications 1Z0-510 Questions & Answers

• Question 31:

  What can be done to prevent inventory data deadlocks in the database?

  A. Use inventoryRepository's built locking mechanism to avoid this issue.

  B. No additional step needed. Transaction Manager has a dead lock listener.

  C. It is controlled via the invontoryLockEngine on the Client Lock Manager, which locks the inventory.

  D. Use inventory Manager's acquireinventoryLocks and releaselnventoryLocks methods.

  E. Apply database optimistic locking on the inventory table.

  F. Use Custom extensions to the inventory System.

  Correct Answer: D

  Preventing Inventory Deadlocks

  InventoryManager includes the acquireInventoryLocks and releaseInventoryLocks methods. These methods can be used to prevent deadlocks in the database, especially if there are multiple ATG Commerce instances concurrently updating inventory.

• Question 32:

  Which component do you need to configure to use a different hardgoodShippingGroup class?

  A. OrderManager

  B. Order Tools

  C. ShoppingCart

  D. ATG does not allow you use a different hardgoodShippingGroup

  Correct Answer: C

  Adding Shipping Information to Shopping Carts

  Adding shipping information to shopping carts involves the following subprocesses:

  *

  Creating a list of shipping groups for potential use in the current order. The user can select from among these shipping groups when checking out the order.

  *

  Specifying the shipping groups to use with the current order.

  *

  Selecting the shipping methods, such as Ground or Next Day, for the order's shipping groups.

• Question 33:

  What is the likely outcome when a product's end date is set in the past?

  A. ATG automatically stops showing the product when category.ChildProducts is invoked.

  B. Developer of the site has to have a rule to check the date and decide if the product can be displayed.

  C. ATG deletes the product and hence is never shown on the site.

  D. END date is a display only field and has no impact on the product's visibility.

  Correct Answer: A

  Note:

  * End date

  Date the product is no longer available, if a collection filter is implemented to use this property.

• Question 34:

  Which statement is true regarding hidden fields on the dsp:form?

  A. User defined hidden fields are not allowed. ATG will use hidden fields for internal tracking.

  B. User defined hidden fields are allowed but they can only pass static or EL values, to form handlers for additional processing logic.

  C. User defined hidden fields are allowed and they can set component properties on form submission. However only static and EL values are allowed as a value.

  D. User defined hidden fields are allowed and then can set component properties on form submission. The value can either be static or a param field bean attribute.

  Correct Answer: C

  Note 1: You can use hidden input fields to differentiate various forms. This mechanism is especially useful when you generate multiple forms dynamically; in this case, you can test the value of each form's hidden input field to determine which

  form to render.

  Note 2: dsp:form

  Sets up a form for user input.

  method="{get|post}"

  [action="jsp-page"]

  [synchronized="component-spec"]

  [formid="id"] [requiresSessionConfirmation="{true|false}"] Note 3: EL Variable: Expression Language variable

  You can set any Nucleus component and Dynamic Bean to a variable that can then be referenced by the JSP Expression Language (EL). The DSP tag library provides three tags for setting components to EL variables:

  *

  dsp:getvalueof enables access to standard JavaBean components, page parameters and constant values.

  *

  dsp:tomap enables access to non-standard Dynamic Beans--for example, a RepositoryItem.

  *

  dsp:importbean, which imports Nucleus components into a JSP, can also be used to set standard Java Bean components to EL variables.

• Question 35:

  Invoking Full Deployment on Production will cause ___________.

  A. Temporary loss of data interrupting a customer's shopping process

  B. Nothing, because if data is already deployed and is current, this action will be ignored

  C. ATG to flush and re apply data on the passive database, switch and then on the other database

  D. ATG to flush and re apply data on the passive database. The active one is not touched to prevent interruption of data

  E. Nothing, because full deployment is a development activity. It is forbidden when the server is in production mode

  Correct Answer: C

  The atg.deployment.DeploymentOptions.addOption method supplies various deployment-wide settings to the DeploymentManager's deploy() method.

  FULL_DEPLOYMENT: Causes a full deployment, where only add operations are included in the DeploymentData, and the deployment deletes any information in the target repositories or virtual file systems that is not included in the

  DeploymentData.

  Note:

  Full Deployment

  A full deployment comprises two steps:

  *

  assets are deleted from the target site.

  *

  All changed assets from the deployed project, and all appropriate existing assets, are deployed to the site.

  Full deployments can be time consuming and resource intensive if the site has a large number of assets.

  However, it is especially useful (and sometimes necessary) to refresh assets when they are modified directly or are corrupt. It is also practical for small sites with few assets, as it can be performed relatively quickly.

  Note #2:

  *

  Configuring and Running a Full Deployment

  In the following procedure, you perform a full deployment to transfer assets from the Publishing server to the Production server. Assets are persistent, publishable objects such as scenarios, user segments, and HTML files that are used by

  ATG applications. After the initial installation and configuration through CIM, the ATG Store assets exist on the Publishing server but they must be deployed to the Production server to be accessible from the ATG Store website.

  *

  Full Deployment

  A full deployment copies all assets from the asset management server to a target site. A full deployment comprises two steps:

  All assets are deleted from the target site.

  All assets from projects that are currently and previously deployed to the target site are written to that site.

  Note: A full deployment to a one-off target only includes assets from checked-in projects. Assets from deployed but still-active projects are excluded from the deployment.

  On a site with many assets, full deployments can be time consuming and resource intensive. Initiate a full deployment in order to refresh all site assets, especially when they are modified directly or are corrupt.

• Question 36:

  Which three methods are recommended for removing a profile marker from the profile?

  A. the "deleteMarkers" method on the atg.markers.userprofiling.ProfileMarkerManager class

  B. Use a scenario with tin- "Remove markers from profile" action.

  C. Use the ProfileMarkerDmplot.

  D. Use the RemoveAllMarkersFromProfileDroplet.

  E. Profile markers are automatically deleted at the end of the session.

  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.

• Question 37:

  Which two items can only be created in the ATG Control Center (ACC)?

  A. User profiles, roles, and organizations

  B. Content items

  C. Scenarios and slots

  D. Content Groups

  E. Content Targeters

  F. Workflows

  Correct Answer: CF

  Note: When you start the ATG Control Center, the following screen appears:

• Question 38:

  Which is a valid list of component scopes?

  A. Singleton, Session, Request

  B. Global, Session, Request, Dynamic

  C. Singleton, Prototype, Request, and Session

  D. Global, Session, Request, and Window

  E. Singleton, Global, Session, Request

  Correct Answer: D

  An application component can be set to one of the following scopes:

  *

  Global: Component is shared among all users.

  *

  Session: Separate instances of the component are provided to each user.

  *

  Request: Separate instances of the component are provided to each active request.

  Note: ATG support Window scope which allows you to associate specific component instances with a specific browser window. Such components need to live longer than a request and also need to be different for every browser window associated with the user's session.

• Question 39:

  Which four droplets can be used in ATG applications?

  A. Cache

  B. Catalog

  C. ForEach

  D. IsEmpty

  E. IsNull

  Correct Answer: ACDE

  A: The Cache droplet caches the rendered output of the contents of the oparam based on a content key (such as category, user gender, logged in/logged out state, etc..) for a configured period of time. This can be very useful for things like navigation menus dynamically built based on the catalog.

  C: ForEach Droplet: ("atg.droplet.ForEach" is the class, Component is "atg/dynamo/droplet/ForEach") help us to iterate through the elements of an array which we specify. The droplet helps us to specify the HTML before and after the array processing also to specify the HTML if the array is empty.

  D: IsEmpty

  Displays one of two possible outputs, depending on whether its input parameter is empty.

  *

  Class Name

  atg.droplet.IsEmpty

  *

  Component

  /atg/dynamo/droplet/IsEmpty

  E: IsNull

  Displays one of two possible outputs, depending on whether its input parameter is null.

  *

  Class Name

  atg.droplet.IsNull

  *

  Component

  /atg/dynamo/droplet/IsNull

• Question 40:

  When using programmatic repository data access, each database operation is automatically wrapped in transaction of which mode?

  A. Required

  B. Supports

  C. Mandatory

  D. RequiresNew

  E. NotSupported

  Correct Answer: B

  The TransactionServlet can be configured to cause each request to be wrapped in a transaction. By default, theTransactionServlet's transAttribute property is set tosupports, which means a new transaction is not created for each request. In most circumstances, the transAttributeproperty should remain set to supports. In all cases, theTransactionServlet checks to see if the request created a Transaction without ending it. If so, the servlet rolls back that Transaction and reports an error.
