Which of the following queries allows users to search by name and age?

The query that allows users to search by both name and age is the Driver's License by Name Query (DNQ). This query specifically focuses on retrieving information related to driver's licenses while enabling the search to be refined by inputting the name of the individual. When name is input, it's typically accompanied by age or date of birth to ensure accuracy and specificity in the results returned.

In contrast, the other options do not provide the capability for such a precise search for both factors. The Driver's License Query (DQ) may offer a broader range of data but is not explicitly designed to filter the results based on age along with the name. The Driver's History Request (KQ) primarily focuses on an individual's driving history, which is not aimed at searching by name and age in tandem. Lastly, the Out of State Driver's License Query, as the name suggests, pertains specifically to licenses issued outside the current state and does not inherently incorporate a search by name and age.

Therefore, the DNQ is uniquely structured to address the need for searching by both name and age, making it the correct choice for this query type.
