An administrator wants to run secure commands as user1 from hosta to hostb using OpenSSH. Which actions will configure SSH trust?

Generating the public/private key pair on hosta is the correct starting point because hosta initiates the connection - the private key remains on hosta while the public key is appended to user1's ~/.ssh/authorized_keys on hostb. This allows hostb to verify hosta's identity without a password, establishing the trust relationship in the correct direction.

Keys must be generated on the initiating host (hosta), not the destination; generating them on hostb would configure trust for connections originating from hostb, not hosta.

Key generation alone does not establish trust - the public key must also be copied to hostb's authorized_keys file for the authentication to succeed.

Without completing the distribution of hosta's public key to hostb's authorized_keys, the key pair exists but SSH trust between the two hosts is not actually established.
