Final answer:
The distinguished name (DN) for Ella Parker, who is in the Marketing OU, would be 'CN=Ella Parker,OU=Marketing,DC=domain,DC=com', assuming 'domain.com' is the domain name. This DN uniquely identifies Ella within the Active Directory hierarchy and follows LDAP conventions.
Step-by-step explanation:
The distinguished name (DN) for a user account in a domain typically includes the common name (CN) of the user, the organizational unit (OU) they are in, and the domain components (DC) of the domain. For a user named Ella Parker who resides in the Marketing OU, the DN would be formatted like this:
CN=Ella Parker,OU=Marketing,DC=domain,DC=com
This assumes that 'domain.com' is the domain name. The DN is a unique identifier that follows the LDAP (Lightweight Directory Access Protocol) conventions and is used to define the location of an object within the Active Directory hierarchy.
