To compete in today's fast-paced competitive environment, organizations are increasingly allowing contractors, partners, visitors and guests to access their internal enterprise networks.These users may connect to the network through wired ports in conference rooms or offices, or via wireless access points. In allowing this open access for third parties, LANs become(6) .Third parties can introduce risk in a variety of ways from connecting with an infected laptop to unauthorized access of network resources to(7)activity. For many organizations, however,the operational complexity and costs to ensure safe third party network access have been prohibitive. Fifty-two percent of surveyed CISOs state that they currently use a moat and castle's security approach, and admit that defenses inside the perimeter are weak. Threats from internal users are also increasingly a cause for security concerns. Employees with malicious intent can launch (8) of service attacks or steal (9) information by snooping the network. As they access the corporate network, mobile and remote users inadvertently can infect the network with (10) and worms acquired from unprotected public networks. Hackers masquer-ading as internal users can take advantage of weak internal security to gain access to confidential information.

our network consists of a single Active Directory domain. All network servers run Windows Server 2003 Service Pack 2 (SP2). The network contains a single subnet. The network connects to the Internet by using a network address translation (NAT) device. You deploy a new DHCP server named Server1. You create a scope as shown in the exhibit. (Click the Exhibit button.) You need to ensure that client computers can connect to the Internet. What should you do?()A、Add a Router scope option. B、Enable conflict detection on the DHCP server. C、Remove the WINS/NBT Node Type scope option. D、Configure the scope to respond to a BOOTP request only.
