What schema files are required to make LDAP compatible to NIS? (Choose TWO correct answers.)

`misc.schema` contains various general-purpose schema elements but is not specifically required for NIS compatibility.

The `cosine.schema` provides fundamental object classes like `posixAccount` and `posixGroup`, which are essential for representing Unix-like user and group information that NIS systems rely upon. These definitions are building blocks for storing user accounts and groups in the directory.

The `nis.schema` specifically defines object classes and attributes (e.g., `nisMap`, `nisObject`, `nisNetgroup`) that enable an LDAP directory to store and serve Network Information Service (NIS) map data, allowing LDAP to function as a backend for NIS services.

`inetorgperson.schema` defines the `inetOrgPerson` object class, primarily used for representing internet-enabled organizational persons, and is not directly related to NIS functionality.
