You have defined two independent extensions. (1) extension1-beans.xml:  (2) extension2-beans.xml:  . When you execute "ant all", what will happen?

Choose the correct answer.

Ant fails to build, because we can’t define the same DTO class in two different extensions

Ant build is successful, with only class A generated in the platform extension

Ant build is successful, with two classes of A generated in the two different extensions 

Ant fails to build, because the compiler doesn’t know from which extension the class A can be generated first

 You extended the product type by injecting an additional attribute to the product type. You also want to show the new attribute value on the product detail page. What should you do to proceed?

Choose the correct answer.

The new attribute will be handled by the default product converter automatically

Extend the product DTO to include the new attribute, then do a mapping from the new attribute in items.xml to the beans.xml, so that the default product converter can populate the value directly

Extend the product DTO to include the new attribute and Implement a new converter to convert it

Extend the product DTO to include the new attribute. Then, implement a new populator to fill the value. And finally, append the populator to the default product converter

What can you do with a populator?

There are two correct answers.

You can call other SAP Commerce services to implement your custom calculation for the value population

You should leave the custom calculation to the converter and only concentrate on setting values in the populator

You can set attributes’ values from an object of type A to an object of type B

You can convert an object of type A to an object of type B
