For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    The DMS replication instance does not have network access to the source database.

    Why it's wrong here

    Network issues would cause a different error.

    Why this is correct

    ORA-01017 indicates invalid username or password.

  • ✗

    The DMS task requires additional IAM permissions.
