Multiple choice questions about network security deployment have answers

With these useful network security tests, you will reinforce your knowledge.

Question 1. Internet connection sharing capability is built into the operating system
1. Windows 95/98/2000 / XP / 2003
2. Windows 98SE, Windows 2000, Windows XP, Windows Server 2003/2008
3. Windows Server 2000, 2003
4. Windows Server 2003/2008
Question 2. The common method for sharing an internet connection for many other computers in the network is:
1. NAT (Network Address Translation)
2. ROUTE (Routing Service)
3. RAS (Remote Access Service)
4. ICS (Internet Connection Sharring)
Question 3. Windows Server 2003 machine has 2 network communication devices: an Internet communication and a communication with the Client. Administrators deploy NAT on this Windows Server to share internet connection. After the deployment is completed, the server communicates internet well, and the clients do not communicate, although they have correctly and sufficiently declared IP parameters for clients. Causes of this situation:
1. Because the OS on the Client does not support internet communication via NAT Server
2. Because Windows Server uses Standard version, SecureNAT is not supported
3. Because the 'Basic Firewall' service prevents Internet clients from communicating
4. When deploying NAT, the administrator has chosen the wrong internet communication device
Question 4. A Windows Server 2003 computer named SERVER1 was previously built into an FTP Server that provides Files for internal users and users of Enterprise branches. Enterprise uses SERVER1 to share SecureNAT-style internet connection for other machines. When the Administrator executes SecureNAT using RRAS's Wizard. He selected 'Network Address Translation (NAT)' and clicked 'Next' until 'Finish'. Result:
1. The users at the branch will not be able to access the data in FTP because when logging into the FTP Server, the Username / Password are denied by the Server.
2. Users inside the network of SERVER1 will access FTP normally but cannot communicate with the internet
3. Users at branches still access data on FTP Server as usual
4. Users at branches will not access data in FTP on SERVER1
Question 5. A computer connected to the internet by ADSL technology. When the internet connection is successful, the ISP will issue an IP address. In the absence of any other intervention, choose the correct statement.
1. That IP address is assigned to the RJ-45 port network device on the ADSL modem
2. That IP address is assigned to the network interface card on the user's computer
3. That IP address is assigned to the RJ-11 port network device on the ADSL modem
4. That IP address is issued to the user's computer
Question 6. Previously, the Technical Department of an Enterprise had only one computer running Windows Server 2003 named SERVER1. Administrators often use Remote Desktop to run this machine from his home. The enterprise equips the 10-Computer Technical Department and uses SERVER1 to share internet connection with SecureNAT. After sharing the internet connection successfully, the administrator no longer uses Remote Desktop to operate SERVER1 from home. The best solution to fix this problem:
1. Change the account that is authorized Remote Desktop machine SERVER1
2. Turn off Basic Firewall on the server SERVER1
3. Turn off the Remote Desktop service on SERVER1 and re-create this service
4. On the Basic Firewall of server SERVER1: open port 3389 and transfer it to the IP address of the server itself SERVER1
Question 7. IT Training School iSPACE has many branches. Accountants at Branches want to share accounting information with each other. Which of the following solutions is feasible today?
1. With Internet connection available, deploy VPN system for Branches
2. Use Remote Dial-up to dial a network number from Branch A to B whenever there is a need to access shared information
3. Each Branch has its own Leased Line subscription. Routing the Leased Line together
4. Use the wire to connect all the Branches together
Question 8. A packet that supports IPSec is encrypted both Header and Content. This encryption method has a name:
1. ESP
2. AH
3. SSL
4. EFS
Question 9. IT Training School iSPACE intends to deploy Site-to-Site VPN connection among Branches but is still concerned about the safety of data when transmitted on internet infrastructure. As a network administrator at the school, which of the following is the solution to overcome this problem?
1. Use IPSec in combination with L2TP protocol
2. Requires internet service provider (ISP) to encrypt data transmitted by VPN from iSPACE to interne
3. Use Encrypt File System (EFS) available in Windows to encrypt files before sharing via VPN
4. Set highly complex passwords for Dial-In Users
Question 10. The employees of Bien Hoa Branch need to access data on computers in the Accounting Department of Phu Nhuan Branch. As a network administrator at iSPACE, you choose the most optimal solution:
1. Set up Site-to-Site VPN type between 2 branches
2. Set up Remote-asccess VPN and grant employees at Bien Hoa Branch account access to Phu Nhuan Branch
3. Set up an FTP Server at Phu Nhuan branch. The accounting data will be included in FTP Site so that Bien Hoa branch staff can access it
4. The data to be retrieved will be sent to the staff of Bien Hoa Branch by the Accounting Department staff
