What term describes permission granted to accounts in one domain to access resources in another domain (one-way) or to allow access both ways (two-way)?

• A. Trust
• B. Firewall
• C. Encryption
• D. Gateway

Answer: (A)

Access across domains is governed by trust relationships. A trust is a defined relationship that lets accounts from one domain be authenticated to access resources in another domain, and it can be one-way or two-way depending on the direction of the access. In a one-way trust, accounts in the trusted domain can access resources in the trusting domain if permissions allow; in a two-way trust, both domains can grant access to each other. This directly describes the permission setup the question asks about. Firewall, encryption, and gateway describe ways to protect or connect networks but do not define the cross-domain authorization relationship itself.
