'title' => QueryInterface::ORDER_DESCENDING
];
...

1. ARecords read from this repository are sorted by their title field in descending order by default
2. BThe additional configuration sortBy is required in the TCA of the repository to set the default sort order
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
5. EIf the property $defaultOrderings would not exist, the repository would use the sorting
  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

1. ANothing needs to be configured as this is the default
2. BThe TypoScript configuration persistence.storagePid needs to be set to all

13How can a custom extension access the fe_users database table? (2)
1. ABy extending the domain model TYPO3\CMS\Extbase\Domain\Model\FrontendUser
2. BBy adding the mapping as TypoScript

17Which statments about the following TypoScript code are correct? (2)

plugin.tx_myextension {
persistence {
classes {
Vendor\MyExtension\Domain\Model\Client {
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

2. BYes, if the relation has the annotation @selfreference
3. CYes, if the TypoScript key features.selfreference = 1 is set

5. EThis is not possible – an error message is generated
19How can we make a TypoScript object available in a controller? (1)
1. AVia $this->configurationManager->getContentObject()->data
2. BVia $this->cObj
