runs Windows Server 2008 R2.You have a folder named Data that is located on the C drive. The folder has the default NTFS permissions configured.A support technician shares C:\Data by using the File Sharing Wizard and specifies the default settings.Users report that they cannot access the shared folder.You need to ensure that all domain users can access the share.What should you do？（）

A. Enable access-based enumeration (ABE) on the share.

B. Assign the Read NTFS permission to the Domain Users group.

C. From the Network and Sharing Center, enable public folder sharing.

D. From the File Sharing Wizard, configure the Read permission level for the Domain Users group.

added to the Active Directory and placed into the Domain Users group and the SW_DEV group. The Domain Users group has access to the company‘s intranet website and time card system. The SW_DEV group has access to the source code library server. You have created roles that correspond to each Active Directory group. The user calls the help desk stating that they cannot access the source code library server.Which two troubleshooting tools would you use on the Junos Pulse Access Control Service to resolve the issue？（）

A. Perform a policy trace for the specific user and review the output to isolate the problem.

B. Review the Events log.

C. Review the Admin Access log to verify that the user has the correct permissions to access the SVVJDEV resource.

D. Review the User Access log to verify that the user is getting mapped to both the Domain User role and the SW_DEV role.

mand for mobile date service. In addition mobile users also expect to connect to the Internet for communicate and access to services through the best suitable connection, anywhere and at anytime. Although the seamless roaming capability is well supported in conventional. Cellular communication networks, roaming and interworking technologies are still immature in heterogenous wireless networks. Seamless roaming over heterogenous wireless networks will be an ongoing and improved process, due to the requirements from both end users and network administrators. From the wireless access networks belonging to different administrative domains, mobile users cannot always identify at every instance which network is the best one to access for their service. It is highly demanded to establish a network architecture which can facilitate mobile terminals to access the appropriate network in a cost-effective way. If a mobile user wants to move from one network to another with continuous service, the terminals have to cope with network change to maintain service seamlessly. Quality of service is a major issue that the end users should be provided with the satisfying service, while the network workload and cost should not too much increased. In addition, since end users are provided with numerous service ranging from Voice-over-IP to Video-on-Demand services, it is expected that users can experience the same quality for all the different service. Therefore, the network architecture need to be designed in such a way that the quality mechanism is incorporated so that users are served according to their individual QoS requirements.
