Answers

1.	Peer-to-peer networks do not use dedicated network servers for authenticating users and providing secure access to network resources. In this model, clients share resources, and other clients have access to whatever has been shared.
2.	The role of the primary domain controller, or PDC, is to store the domain accounts database, called the Security Accounts Manager, or SAM. The PDC also sends updates of the SAM database to any BDCs within the domain.
3.	BDCs offload logon authentication from the PDC. They also provide fault tolerance if the PDC is offline.
4.	Directory services model
5.	False. Each network model has its own strengths and drawbacks. No one network model meets the needs of every network.
6.	Peer-to-peer network
7.	An object is a logical representation of anything that can be managed on the network, including user accounts, servers, and printers.
8.	False. In a client-server model, you need an account on each server on which you want to access resources.
9.	False. You can add users to the PDC or the BDC. The account information is automatically updated to the other server.
10.	The directory services network model
