Practice Questions

Question 1 Which of the following naming services requires the data to be configured manually on every system on which it is used?
  • a. NIS

  • b. NIS+

  • c. DNS

  • d. /etc files

A1: Answer d is correct. NIS requires the data to be configured manually on every system on which it is used. All the other naming services provide a means to update one master database and propagate changes to every system that needs them. Therefore, answers a, b, and c are incorrect.

Question 2 Enter the name of a method to restrict access to NIS+ resources based on the user's credentials.
A2: The correct answer is authentication.
