A banking AEM application contains functionality to calculate a mortgage rate based on user input. A servlet in place calculates the result in the backend. A call to an internal third-party REST service is required to retrieve the average object value based on a given zip code.
The following three service interfaces are used:
MortgageCalculationServlet, MortgageCalculationService and ObjectValueLookupRestService where MortgageCalculationServlet has a dependency to MortgageCalculationService and MortgageCalculationService has a dependency to ObjectValueLookupRestService.
The calculation has many combinations of input parameters and edge cases, so the JUnit coverage must be as high as possible.
Which two strategies should the developer use to ensure testability of the application code? (Choose two)

• A. Use static methods to avoid boilerplate in application code
• B. Use BundleContext.getServiceReference(...) and BundleContext.getService(...) in application code to look up for the required services just before usage
• C. Use the standard OSGi @Reference annotation to wire the dependencies in application code
• D. Use a mock framework to be able to create and inject mocks in the test code
• E. Deploy a third party dependency injection container to wire dependencies more efficiently in application code

Which environment variable in the AEM start script should a developer modify to enable remote debugging?

• A. CQ_PORT
• B. CQ_JVM_OPTS
• C. CQ_RUNMODE
• D. CQ_HOST

A developer is creating a new OSGi bundle com.custom.package.b to expose new services.
com.custom.package.a is already installed and active in the system and has the following package definition:

The system console shows the following package availability:

Bundle com.custom.package.b to be installed has the following package definition:

What will happen when the developer uploads the bundle com.custom.package.b into the system?

• A. The bundle will install but fail the activation due to unsatisfied dependency com.sample.package.c.
• B. The bundle will install but fail the activation due to unsatisfied dependency com.sample.package.b.
• C. The bundle will install but fail the activation due to unsatisfied dependencies com.sample.package.b and com.sample.package.c.
• D. The bundle will install and activate successfully.

A developer creates two custom classes. ClassA has the following code:
package com.aem.abc;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class ClassA {
private static final Logger logger = LoggerFactory.getLogger(this.getClass()); public void classAMethod() { logger.debug("Message from Class A method");
}
}
The developer creates a custom log custom.log with debug level in OSGi sling log support for the Java package com.aem.abc. The developer adds another class ClassB with the following code:
package com.aem.xyz;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class ClassB {
private static final Logger logger = LoggerFactory.getLogger(this.getClass()); public void classBMethod() { logger.debug("Message from Class B method");
}
}
Which action must the developer take to see the log messages in the same file from both classes?

• A. Configure custom.log in OSGi web console -> Sling -> Log Support and replace com.aem.abc with com.aem.xyz
• B. Create separate a log file in the OSGi web console -> Sling -> Log Support for logger com.aem.xyz
• C. Configure custom.log in OSGi web console -> Sling -> Log Support and replace com.aem.abc with com.aem
• D. Configure custom.log in OSGi web console -> Sling -> Log Support and replace com.aem.xyz with com.aem.abc

The developer is presented with a component "Component A" which inherits from a component "Component B".
The dialog of Component A on path ../cq:dialog/../../items looks like:
+ align
- jcr:primaryType="nt:unstructured"
- sling:resourceType="granite/ui/components/coral/foundation/form/select"
- fieldLabel="Align Text"
- name="./align"
The dialog of Component B on path ../cq:dialog/../../items looks like:
+ title
- jcr:primaryType="nt:unstructured"
- sling:resourceType="granite/ui/components/coral/foundation/form/textarea"
- fieldLabel="Title"
- name="./title"
+ description
- jcr:primaryType="nt:unstructured"
- sling:resourceType="granite/ui/components/coral/foundation/form/textarea"
- fieldLabel="Description"
- name="./description"
The requirement for the dialog is that the *Align Text* field is shown after the *Title* field.
What should the developer do without changing Component B?

• A. Move all the nodes under the item node from Component B to Component A and order them according the requirements.
• B. Move the align node from Component A to Component B and order them according the requirements.
• C. Extend Component B with the functionality of Component A
• D. Add the property sling:orderBefore="description" to the align node.
