Solution

20.

The components of the application are defined together in the application profile. Hence, it is correct to call it the application blueprint.

Correct option is (c)

---------------------------------------------------------------------------------------------------------

21.

Early binding is a form of tight binding. In this case, we need to have the application definition separate from the platform where we are deploying. Such a binding is called late binding.

It makes sure that the application definition is separate from the platform.

Correct option is (b)

22.

Adopting cloud has the following advantages:

Hence, all the 3 are valid reasons for adopting cloud.

So, correct option is (d)

---------------------------------------------------------------------------------------------------------

23.

By using an index, we can match for the needed data without retrieving the whole data from the server disk. Storing the whole table is not possible in the app engine. But storing the index makes searches fast.

Correct option is (c)

---------------------------------------------------------------------------------------------------------

24.

JDO can be used for storage of java data objects in the Google datastore.

So, correct option is (b)
