Answer: D

Explanation:
The goal of mobile testing is to ensure that your mobile application meets the requirements that guided its design and development. To help you meet this goal, IBM Mobile Test Workbench for Worklight implements the following stages in the testing process:
Configuration: Set up your test environment with IBM Mobile Test Workbench for Worklight and the SDKs for the mobile operating systems. Install the mobile test client on one or several mobile devices. Ensure that the mobile devices have connectivity through WiFi, 3G, or 4G, and add those devices to the test workbench. * Application preparation: Import the application that you want to test into the test workbench, or use the device to upload the application under test to the test workbench.
A. Test recording: Run the app from the mobile test client to start a recording. The recorder records all userinteractions, sensor inputs, and application behavior, and uploads the recorded data to the test workbench, where it can be converted into a mobile test.
B. Test editing: After recording, you can edit the test in the natural language editor. You can use the mobile dataview to display and select UI elements from the recorded applications. You can replace recorded test values with variable test data, or add dynamic data to the test.
C. Testing: You can deploy and run automated tests on multiple devices to ensure that the app matches theexpected behavior that is defined in verification points. During the run, each verification point is checked and receives a pass, fail, or inconclusive status and functional data is recorded.

An application developer is concerned about how many requests may hit the adapter being created. The developer wants to ensure that the adapter can handle enough requests, but yet not allow requests to overwhelm the system.
What can the application developer do to limit the number of requests that an adapter will handle?

A. In the web server configuration, specify number of requests for MaxClients.
B. In the application server configuration, specify the number concurrent requests for the servlet engine.
C. In the loadContraints element of the adapter XML file, specify the number of requests formaxConcurrentConnectionsPerNode.
D. In the connectionPolicy element of the adapter XML file, specify the number of requests formaxConcurrentConnectionsPerNode.

Answer: D

Explanation:
Tuning Back-end Connections
maxConcurrentConnectionsPerNode – The maximum number of concurrent requests that can be performed on the back-end application from the Worklight server node. The worklight server will create a thread pool with maxConcurrentConnectionsPerNode size for that purpose. This maxConcurrentConnectionsPerNode parameter is set in the adapter.xml in the connectivity entry.

Question: 24

An application developer is attempting to update specific portions of a hybrid application by utilizing the direct update feature.
Which components can the application developer update using the direct update feature without having to rebuild and deploy a new binary of the application?

A. HTML, CSS, JavaScript
B. HTML, CSS, JavaScript, Java
C. HTML, CSS, JavaScript, Objective C
D. HTML, CSS, JavaScript, Version number

Answer: A

Explanation:
When you want to deliver a Worklight hybrid application that consists mainly of HTML5 with CSS and JavaScript, and you must change the hybrid part of the application to provide new features or to fix a defect, you do not have to ask the application users to update it on their devices. You can use the Worklight direct update mechanism to deploy new HTML with CSS and JavaScript for your application without changing the application version on the mobile device.
Incorrect:
Not D: Delivering a new version of native code
The main reason that you would want to deliver a new version of an application is probably because your application uses native code and you want to provide new features or deliver fixes that require changes in the native code. You might also need to provide a new native version of the application, even if your Worklight application is completely written by using web technologies, to accommodate new mobile operating systems supported only in later versions of IBM Worklight. You cannot use the direct update mechanism in either of these cases. You must build and deploy a new version of the application.
Reference: http://www.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.dev.doc/devenv/ c_update_apps_wl_ac.html

Question: 25

The application developer needs to test the Worklight application on a remote server. In Worklight Studio, the application developer configures the remote server by right clicking on the {app_name} folder and selecting Run As > Build Settings and Deploy Target.
Which step does the application developer need to perform to ensure the server configuration changes are reflected in the application?

A. Run As > Run on Server
B. Run As > Build and Deploy
C. Run As > Apply Build Settings
D. Run As > Build All Environments

Answer: D

Explanation:
The Build Settings and Deploy Target dialog is used only to specify configurations and settings; clicking OK does not trigger a build. Any time that you make a modification with this dialog, you must rebuild your application and environments for your changes to take effect, by using the Run As > Build All Environments menu command.

D. externalServerLibraries folder – Contains references for application development and deployment.

Answer: C

Explanation:
The bin folder contains project artifacts that are deployed to MobileFirst Server.
Incorrect:
Not D: externalServerLibraries: Contains the libraries to be placed in external service servers and used for access token validation (by the service).
