Question 1

The following is part of a HTTP adapter invocation result.
{
"college":{
"class":{
"description": "Class object"
"student": {
"description": "Students marks details",
"title":Top Stories"
},
"studentmarks": [
{
"name": "Mirjana Lucic-Baroni.",
"marks": "90",
"level": "Level one"
}
{
"name": "Rose Way.",
"marks": "87",
"level": "null"
}
]
}
} }
An application developer needs to send only the 'name' and 'marks' information to a mobile
application using the adapter xsl file.
Which xsl file code snippet will enable the application developer to achieve this?

A. {
'Items': [
<xsl:for-each select="//studentmarks">
{
'name': '<xsl:value-of select="name"/>',
'marks': '<xsl:value-of select="marks"/>',
},
</xsl:for-each>
]
}

B. {
'Items': [
<xsl:for-each select="//college">
{
'name: '<xsl:value-of select="college.name"/>',
'marks': '<xsl:value-of select="college.marks"/>',
},
</xsl:for-each>
]
}

C. {
'Items': [
<xsl:for-each select="//item">
{
'name': '<xsl:value-of select="name"/>',
'marks': '<xsl:value-of select="marks"/>',
},
</xsl:for-each>
]
}

D. {
'Items': [
<xsl:for-each select="//student">
{
'name': '<xsl:value-of select="student.name"/>',
'marks': '<xsl:value-of select="student.marks"/>',
},
</xsl:for-each>
]

Question 7

Before deploying the application to production, the application developer wants to test the application on a
physical device.
After connecting the device via a USB cable to the computer where the application will be tested, which of the following required actions must the application developer perform in order to test the application on a device?
Android:
- Android:
-- --
Enable ''USB debugging'' on the device.
Right click on the {Project_Name}{App_Name}Android project and select Run As >
Android StudioProject
iOS:
-
Obtain a developer certificate to sign applications.
Obtain a provisioning profile that identifies the developer certificate, the device,
and the applicationswhich can be run on the device.
Open the Project in Xcode, select the actual device in the Scheme menu, then
click Run
iOS:

A. Set worklightSettings property to false in the application-descriptor.xml

B. Obtain a developer certificate to sign applications.

Question 8

An application developer is attempting to implement device single sign-on (SSO) as
specified in the following example:
<securityTests>
<mobileSecurityTest name="FormTest">
<testDeviceID provisioningType="none"/>
<testUser realm="SampleAppRealm"/>
</mobileSecurityTest>
</securityTests>
<realms>
<realm name="SampleAppRealm" loginModule="MyLoginModule">
<className>com.worklight.core.auth.ext.FormBasedAuthenticator</className>
</realm>
</realms>
<loginModules>
<loginModule name="MyLoginModule"
ssoDeviceLoginModule="WLDeviceAutoProvisioningLoginModule">
className>com.worklight.core.auth.exp.NonValidatingLoginModule</className> </loginModule>
</loginModules>
Upon testing the configuration, the developer finds unexpected results, such as the Worklight project failing to start.
What does the application developer need to do to bring the SSO configuration to a consistent state?

A. Add the following line to the WMAppManifest.xml file: <Capability Name='ID_CAP_IDENTITY_DEVICE' />

B. Specify <testUser realm="SampleAppRealm" sso="true"/> in the mobile security test.
