3 Your current network layout looks like the one shown in the following illustration All the networks use 100Mbps Ethernet Server A and Server B are file servers used by the clients attached to the switched Hubs C and D Clients on Hub E do not need to access Server B, and vice versa After monitoring the network performance on shared Hub C, you notice that utilization of these two servers is high There are spare ports on all hubs How would you improve performance on your network (Choose two; each answer is a complete solution)

Replace Hub E with a switched hub Move Server A to Hub C and Server B to Hub D Replace Hubs C and D with shared hubs Place Server A and Server B on a new switched hub connected to Hub E E Place Server A to Hub D and Server B to Hub C

4 Your company requires a connection to the Internet to send e-mail You do not want to provide web access to your users, and you want to keep costs as low as possible There are only 20 people in your company and you initially expect only light e-mail use You also want to ensure that the connection is secure and won t expose your network Which Internet connection method should you use (Choose two, each answer presents a whole solution)

A ADSL connection with Internet Connection Sharing (ICS) B Leased-line access using Network Address Translation (NAT) C Dial-up connection using Internet Security and Acceleration (ISA) Server D Dial-up connection with Internet Connection Sharing (ICS) 5 Branch offices at your company are directly attached to your network through a series of leased lines and routers There are a total of about 250 clients spread over the various offices Different offices use a different Class C network address from the private 192168xx range You want to provide Internet access to your users but do not need to share any of your servers over the Internet You also want to maintain a high level of security What method should you use for connecting your users to the Internet (Choose one) A Use manual routes within Routing and Remote Access Service (RRAS) B Use Internet Connection Sharing (ICS) and the Internet Connection Firewall (ICF) C Use Network Address Translation (NAT) D Use Internet Security and Acceleration (ISA) Server 6 You are about to install a permanent connection to the Internet and you want to install a web server to share your company s website Your Internet Service Provider has provided you with a number of fixed IP addresses, and you connect to the Internet through a dedicated router connected to a leased line You need to set this up while ensuring the maximum security for your internal network and the web server to prevent malicious attacks In particular, you want to protect your internal network from malicious attacks that may come from your web server What solution should you use to provide the best security (Choose one) A Use Internet Connection Sharing (ICS) and the Internet Connection Firewall (ICF) to provide Internet connectivity, with the web server connected to your internal network B Use Network Address Translation (NAT) to connect to the Internet and configure a port redirection from port 80 to your web server, which is connected to your internal network

C Use Internet Security and Acceleration (ISA) Server to connect to the Internet and then use another ISA Server to create a DMZ and place the web server within the DMZ D Use NAT to connect to the Internet, placing your web server on the same network as your Internet router 7 One of your computers cannot resolve names either for sites on the Internet or the machines within your network You are using DHCP to allocate addresses and DNS server information to all of your 200 computers Other computers within the network are unaffected You run ipconfig and it tells you that the IP address allocated to this machine is 169254023 What should you try first to resolve the problem (Choose one) A Configure a static IP address for this machine within the DHCP scope B Configure a manual DNS server C Renew the DHCP lease with ipconfig /renew D Flush the DNS cache with ipconfig /flushdns 8 Your network is laid out like the network shown in the following illustration ClientA is unable to connect to the Internet but can communicate with the other servers and clients on the network What should you change to enable Internet access on this machine (Choose one)
