NEW QUESTION 12
An application contains an OSGi configuration that contains a password.
How should a developer prevent this sensitive information from being stored in plain text in JCR?

• A. 1. Use console at /system/console/crypto to encrypt the value2.

NEW QUESTION 18
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.
