Practice Questions

Question 1

Which of the following statements are true regarding Internet Connection Sharing?

  • A. ICS is available only on computers running Windows 2000 Server.

  • B. ICS assigns internal clients IP addresses from a fixed range.

  • C. ICS supports multiple public IP addresses.

  • D. ICS is enabled through Routing and Remote Access.

A1:

Answer B is correct. ICS includes the DHCP allocator that assigns clients on the local area network IP addresses from the range of 192.168.0.1 to 192.168.0.254 . This is a fixed range and therefore cannot be changed. Answer A is incorrect because ICS can be enabled on Windows 2000 Professional, Windows 2000 Server, as well as Windows 98 and Windows Me. Answer C is incorrect because ICS only supports using a single public IP address. Answer D is incorrect because ICS is enabled through the properties for the Internet connection.

Question 2

You have recently moved your small office into a new location. The network now consists of five computers with no plans for expansion. You perform all network administrative tasks , although your experience and knowledge is very limited. There is currently one Internet connection. Which of the following is the best solution for Internet connectivity?

  • A. Enable ICS on one of the computers.

  • B. Configure each computer with its own Internet connection.

  • C. Enable NAT on one of the computers.

  • D. Enable RIP on one of the computers.

A2:

Answer A is correct. The best solution for the scenario is ICS because ICS requires little or no configuration. Answer B is incorrect. Although it is a possible solution, it would add unnecessary costs. Answer C is incorrect. Although NAT could be used, ICS would be a better choice for someone who has limited experience. Answer D is incorrect because RIP is a routing protocol used to dynamically update routing tables.

Question 3

Which of the following components are included with ICS? [Choose all that apply.]

  • A. NAT

  • B. DHCP Allocator

  • C. DNS Proxy

  • D. Groups-based access control

A3:

Answers A, B, and C are correct. ICS includes the following components: Network Address Translation, DHCP Allocator, and the DNS Proxy. Answer D is incorrect because ICS cannot control access to the Internet through groups. All computers enabled as DHCP clients on the internal network can access the Internet through the ICS enabled computer.

Question 4

A friend has recently purchased a new computer for his home office. His existing computer has a dial-up connection to the Internet. He wants to share the existing connection between both computers. He calls you and asks how he can enable ICS. Which of the following statements are correct?

  • A. Add the NAT protocol through Routing and Remote Access.

  • B. Enable ICS through the properties of the RRAS server.

  • C. Enable ICS through using the properties of the Internet connection.

  • D. Add the ICS component through the Add/Remove Programs applet.

A4:

Answer C is correct. ICS can be enabled through the Properties of TCP/IP for the Internet connection. Therefore, answers A, B, and D are incorrect.

Question 5

You have just finished installing the NAT protocol on a Windows 2000 Server. The internal network has 15 Windows 2000 Professional clients. The Windows 2000 Server has the only Internet connection. Its local interface is assigned the IP address of 192.168.0.1 . Both the private and public interfaces have been added. What should you do next to ensure the server can perform translations?

  • A. Configure a special port.

  • B. Create an IP address reservation.

  • C. Enable TCP and UDP header translation.

  • D. Configure an IP address pool.

A5:

Answer C is correct. Once the public and private interfaces have been configured, you enable TCP/UDP header translation on the public interface to ensure proper translation of IP datagrams. Answer A is incorrect because special ports are configured to make internal resources accessible to external clients. Answer B is incorrect because an IP address reservation is configured to reserve one of the public IP addresses for an internal computer. Answer D is incorrect because an address pool is configured when a NAT server has been assigned multiple public IP addresses.

Question 6

Your NAT server has been assigned three public IP addresses: 205.200.2.10 , 205.200.2.11 , and 200.205.2.12 . There is a Web server on the internal network that should be accessible to Internet clients using the same public IP address. How should you proceed?

  • A. Configure a reservation.

  • B. Create a DHCP exclusion.

  • C. Configure a special port.

  • D. Enable TCP/UDP header translation.

A6:

Answer A is correct. By creating a reservation, one of the public IP addresses can be mapped to a computer on the local area network. This makes the computer accessible to Internet clients using the same public IP address. Answer B is incorrect because a DHCP exclusion ensures a computer is always assigned the same IP address. Answer C is incorrect because a special port maps specific incoming requests to an internal IP address and specific port. Answer D is incorrect because enabling TCP/UDP translation only allows NAT to change portions of the IP Datagram for outgoing requests .

Question 7

You have been assigned a single public IP address from your ISP. All clients on the local area network access the Internet through a single Internet connection. You want to make the Web server on the internal network accessible to external users. How should you proceed?

  • A. Configure a special port.

  • B. Create a reservation.

  • C. Enable TCP/UDP headers.

  • D. Configure the Web server with its own connection.

A7:

Answer A is correct. By creating a special port, incoming traffic for a specific port on the public interface can be routed to a specific port on an internal computer, such as a Web server. Answer B is incorrect because the NAT server is configured with only a single public IP address. Answer C is incorrect because this option enables NAT to translate IP datagrams. Answer C is incorrect. Although it is a feasible option, it would be more cost effective to use the built-in features of NAT.

Question 8

Your NAT server has been assigned a pool of public IP addresses. How can you configure the public interface with the range of IP addresses allocated by your ISP?

  • A. Configure multiple IP addresses through the properties of TCP/IP.

  • B. Use the Address Assignment tab within the Network Address Translation properties window.

  • C. Use the Address Pool tab within the Network Address Translation properties window.

  • D. Use the Address Pool tab within the properties window for the public connection.

A8:

Answer D is correct. To configure the a range of public IP addresses assigned by an ISP, use the Address Pool tab from the public interfaces Properties window. Therefore, answer C is incorrect. Answers A and B are incorrect because the Address Assignment tab is used to configure whether the DHCP Allocator is used to assign IP addresses.

Question 9

You have a small home office that is connected to the Internet with a dial-up connection. You enable ICS to enable the remaining computers to access the Internet via this connection. You want the internal computers to be assigned an IP address in the range of 192.168.1.1 to 192.168.2.10 . How should you proceed?

  • A. Use the Address Assignment tab from the TCP/IP properties window to change the IP address range.

  • B. Use the Address Assignment tab from the Network Address Translation properties window to change the IP address range.

  • C. Use the Registry Editor to change the IP address range.

  • D. This cannot be configured.

A9:

Answer D is correct. ICS includes a DHCP Allocator. The range of IP addresses assigned to clients is a fixed range and therefore cannot be configured. Therefore answers A, B, and C are incorrect.

Question 10

You are the part-time network administrator for a small office that has a single Windows 2000 Server and 20 Windows 2000 Professional workstations. The Windows 2000 Server has the only Internet connection. Currently, the network uses the private IP address range of 192.168.2.1 to 192.168.2.20 . All other workstations now need Internet access. You have been assigned this task with the following requirements:

  • The single connection should be shared between all computers.

  • The solution should impose no additional costs.

  • The existing IP address scheme should remain the same.

  • The internal Web server should be accessible to Internet users.

You propose the following:

  • Enable ICS on the Windows 2000 Server.

  • Enable HTTP port 80 so it is accessible to Internet users.

Which of the following needs are met by your proposed solution? [Choose all that appy.]

  • A. All workstations can share a single Internet connection.

  • B. The solution imposes no additional costs.

  • C. The internal IP address scheme will not change.

  • D. The internal Web server will be accessible to Internet users.

A10:

Answers A, B, and D are correct. By implementing ICS, a single Internet connection can be shared by multiple computers. This solution does not impose any additional costs. By enabling HTTP port 80, an internal Web server can be made accessible to Internet users. Answer C is incorrect because ICS automatically assigns computers an IP address from the network address of 192.168.0.0 . Because this range is not configurable, the internal computers will be assigned new IP addresses.
