  A. applicationmarketplace (such as the Apple App Store or Google Play)
  B. download site
  C. enterprise application store provided by solutions such as the Oracle Mobile Security Suite

• Question 4:

  Which task must you perform if your application needs to access a unique device feature that is not supported out-of-the-box by Oracle MAF?

  A. There is no way to access device features that are not provided out-of-the-box in Oracle MAF.
  B. Develop or use an existing Cordova plug-in for this feature and add it to your MAF application.
  C. Add a native type application feature to your AMX application coded in the native SDK.
  D. Use web service calls to the specific device feature.
  B. Develop or use an existing Cordova plug-in for this feature and add it to your MAF application.

• Question 5:

  In your MAF design, you have defined a "checkout" feature based on a task flow where customers place items into their shopping basket and, at the end of task flow, either purchase the items in the shopping cart or cancel the order. The items in the shopping cart are persisted in a managed bean.

  Which single bean scope is the right option for the shopping cart managed bean?

  A. applicationScope
  B. backingBeanScope
  C. pageFlowScope
  D. requestScope
  E. sessionScope
  F. viewScope
  C. pageFlowScope

  Mobile Application Framework variables and managed bean references are defined within different object scopes that determine the variable's lifetime and visibility. MAF supports the following scopes, listed in order of decreasing visibility:

  Application scope--The object is available for the duration of the application (across features). Page flow scope--The object is available for the duration of a feature (single feature boundary). View scope--The object is available for the duration of the view (single page of a feature).

  Object scopes are analogous to global and local variable scopes in programming languages. The wider the scope, the higher the availability of an object. During their lifespan, these objects may expose certain interfaces, hold information, or pass variables and parameters to other objects. For example, a managed bean defined in application scope will be available for use during multiple page requests for the duration of the application. However, a managed bean defined in view scope will be available only for the duration of one page request within a feature.

• Question 6:

  In an AMX page, you want to hide/show a button based on the mobile device having a camera. Which is a valid EL expression to test for the camera?

  A

• Question 7:

  Which two limitations apply to the REST web services data control?

  A. REST web service data controls can be used only with REST services that do not require authentication.
  B. REST web service data controls support only XMLpayloads.
  C. REST web service data controls support only UTF-8 character encoding.
  D. The REST web service data control wizard does not perform changes on existing REST data controls. If the requirement is to change an existing data control configuration, then the existing data control must be deleted before running the REST service data control.
  C. REST web service data controls support only UTF-8 character encoding.
  D. The REST web service data control wizard does not perform changes on existing REST data controls. If the requirement is to change an existing data control configuration, then the existing data control must be deleted before running the REST service data control.

  The REST web service adapter only supports UTF-8 character set on mobile applications. UTF-8 is embedded in the adapter program. http://docs.oracle.com/middleware/mobile200/mobile/develop/maf-web- services.htm

• Question 8:

  Oracle MAF offers a number of distinct login connection types, each with its own strengths and weaknesses. You need to pick the best connection type for an application you are building. The security requirements for the application, obtained from the business analyst, are:

  The mobile application must be password-protected. The mobile application must let users log in even if there is no network connection. The mobile application must perform access control based on roles and privileges. The mobile application should let users login with their Google, LinkedIn, or Twitter account.

  Given that your organization has already implemented Oracle Access Manager and wishes to reduce the development effort, which login connection type should you choose?

  A. HTTP Basic
  B. Mobile-Social
  C. OAuth
  D. OpenID
  E. SAML
  F. Web SSO
  A. HTTP Basic
  B. Mobile-Social
  C. OAuth

• Question 9:

  In embedding an Android third-party Cordova Plugin into your MAF application, the plugin may include a/resdirectory. What is the purpose of this directory?

  A. It defines a number of Android XML files specifying what device resolutions are supported by the Cordova plugin.
  B. It contains optional pluggable resources that the plugin consumer can bundle into the Cordova plugin at deployment time.
  C. It is a temporary location for build time artifacts.
  D. It contains optional resources required by the plugin at run time such as images, constants, layouts and strings.
  D. It contains optional resources required by the plugin at run time such as images, constants, layouts and strings.

• Question 10:

  Which of the following changes would not improve the performance of the application?

  A. Introduce middle-tier data caching for data that does not change frequently.
  B. Switch the services from SOAP protocol to REST protocol.
  C. Reduce the number of fields returned from the service so that only the needed fields are returned.
  D. Add a layer that fetches the data on the middle tier into a Java class and then expose that class asa SOAP service.
  A. Introduce middle-tier data caching for data that does not change frequently.
