3. CThe property $defaultOrderings has no effect by default
4. DThe constant ORDER_ASCENDING can be used instead of ORDER_DESCENDING to sort in ascending order

  defined in the TCA
10Assuming two domain objects Book and Chapters exist, which have a 1:n-relation. How can you determine all chapters of a book which match a search string? (1)
1. ABy searching in the Book repository and by using in() on the property chapters
2. BBy searching in the Book repository and by using contains() on the property chapters
3. CBy searching in the Chapters repository and by using in() on the property books
4. DBy searching in the Chapters repository and by using contains() on the property books
5. EBy searching in the Chapters repository and iterating all records to find the appropriate

mapping {
tableName = fe_users
columns {
first_name.mapOnProperty = name
}
}
}
}

1. AThe code has no effect: a fully qualified class name must be used as a tableName value
2. BThe property name of the model Client maps to the field first_name of the database table
  fe_users

19How can we make a TypoScript object available in a controller? (1)
1. AVia $this->configurationManager->getContentObject()->data
2. BVia $this->cObj
