Final answer:
The correct response to whether a one-way nontransitive trust can be set up is 'A. True'. This trust relationship is used in network security within Active Directory environments to grant access permissions while keeping strict domain boundaries.
Step-by-step explanation:
To answer the question: 'Set up a one-way nontransitive trust. A. True B. False', it is important to understand what one-way nontransitive trust means in the context of computer networking and security. Within the realm of network security, especially in the management of access between different domains or network segments, a one-way nontransitive trust is a type of trust relationship in which one domain (the trusting domain) allows access to users from another domain (the trusted domain), but the trusted domain does not allow access in the other direction nor does this trust extend to any other domains that the trusted domain may trust. This setup is commonly used in Active Directory environments where there is a need to limit access and maintain strict boundaries between different organizational units.
The question seems to be querying whether setting up such a trust is possible. Since the establishment of one-way nontransitive trusts is a valid configuration in systems like Active Directory, the correct response would be 'A. True'. This type of trust allows an organization to grant specific access permissions while maintaining security and administrative boundaries between domains.
