- In option b, In the AWS there is no use of the replication area, that's why it's incorrect.
- In option c, It is used in a single purpose, that's why it's incorrect.
- In option d, It provides the accessibility to the user to access the large amount of data, that's why it is wrong.
Answer:
The correct option is;
A) Device manufacturers store the initial file-system data structures in the device.
Explanation:
Before a storage device can be used for data storage, it is required to prepare the device for use and to make the device to become visible to the operating system by formatting of the device
New storage devices are not pre-formatted or come with a ready to use file system as there are different file systems specifically designed for particular operating systems or operating environment.
Formatting creates partitions, makes the hard drive visible to the operating system and creates a file system that is new such that the storage device can be used for storing files.

Answer:
A. With content-based filtering, users
receive recommendations for items
liked by similar users.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Content-based filtering uses an algorithm to recommend to users what they like.
The statement about content-based filtering which is false is that, with content-based filtering, users
receive recommendations for items
liked by similar users.
