This intermediate level certification is intended for application developers who have hands-on experience using Worklight Foundation V6.2 to develop mobile hybrid and native applications.

A mobile application developer who achieves this certification can use Worklight Foundation V6.2 to develop client-side applications, develop server-side integration and security components, as well as test and deploy Worklight Foundation V6.2 projects. Overall, a mobile application developer can develop and implement mobile solutions.

The mobile application developer is generally self-sufficient and is able to perform most of the tasks involved in the role with limited assistance from peers and vendor support services. The mobile application developer efficiently uses product documentation.

To attain the IBM Certified Mobile Application Developer – Worklight Foundation V6.2 certification, candidates must pass 1 test. To prepare for the test, it is recommended to refer to the job role description and recommended prerequisite skills, and click the link to the test below to refer to the test objectives (skills measured on the test) and the Test preparation tab.

Each test:
contains questions requiring single and multiple answers. For multiple-answer questions, you need to choose all required options to get the answer correct. You will be advised how many options make up the correct answer.
is designed to provide diagnostic feedback on the Examination Score Report, correlating back to the test objectives, informing the test taker how he or she did on each section of the test. As a result, to maintain the integrity of each test, questions and answers are not distributed.

QUESTION 1
An application developer has determined that Worklight does not provide an authenticator that meets the complex needs of the application being developed. It is decided that the developer must implement a custom authenticator.
Which interface must the application developer implement?

A. com.worklight.core.auth.api.CustomAuthenticator
B. com.worklight.core.auth.api.AuthenticationService
C. com.worklight.server.auth.api.CustomAuthenticator
D. com.worklight.server.auth.api.WorkLightAuthenticator

Answer: D

Explanation:
Your custom authenticator class must implement the com.worklight.server.auth.api.WorkLightAuthenticator interface. References:
https://www.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.dev.doc/ devref/ t_custom_authenticator.html

QUESTION 2
An application developer is using Worklight skins to support multiple from factors on an Android based hybrid application that will run on phones and tablet devices. The developer built skins that modify the color and size of the text in the application based on the device that it is running on. To switch between them, the developer needs to modify a file in the Worklight project.
What is the name of the file that the application developer needs to modify to set the skins to apply at runtime?

A. main.js
B. skinList.json
C. skinLoader.js
D. initOptions.js

Answer: C

Explanation:
To set which skin to apply at run time, implement the function getSkinName() in the file skinLoader.js.

QUESTION 3
An application developer has implemented the following security test to protect a mobile application.
<mobileSecurityTest name=”mobileTest”>
<testUser realm=”myMobileLoginForm”/>
<testDeviceID provisioningType=”none” />
</mobileSecurityTest>
The corporate security team has recently learned about cross-site request forgery (XSRF) attacks against the company’s website. The corporate security team wants to prevent further attacks and has asked the developer to protect the mobile application against XSRF attacks.
What step must the application developer take to protect against XSRF attacks?

A. Nothing. By default, a mobileSecurityTest includes protection against XSRF attacks.
B. Define a new webSecurityTest and add the element <test realm=”wl_antiXSRFRealm”/>
C. Add the element <test realm=”wl_antiXSRFRealm”/> to the mobileSecurityTest definition.
D. Change the implementation to a custom security test and add the element <testXSRF realm=”wl_antiXSRFRealm” />

Answer: A

Explanation:
The mobileSecurityTest contains:
* The following realms, enabled by default: wl_anonymousUserRealm, wl_antiXSRFRealm, wl_remoteDisableRealm and wl_deviceNoProvisioningRealm. * The user and device realms that you must specify.

QUESTION 4
An application developer is developing a native iOS application. The application developer needs to call a web service to retrieve application data. In order to do that, the application developer will call an existing Worklight adapter that retrieves this data.

A. MyInvokeListener
B. WLAdapterDelegate
C. WLAdapterInvocationData
D. WLProcedureInvocationData

Answer: D

Explanation:
The WLProcedureInvocationData class contains all necessary data to call a procedure, including:
The name of the adapter and procedure to call. The parameters that the procedure requires.
