1 DCN-Router-Configuration-HW.doc 1 CSCI 3342 You must do at least 90% of this homework without the assistance of anyone else. Once you have 90% or more of the homework completed, you may double check your answers with a team-mate or study-partner only after you have completed 90% of the work on your own. I have completed at least 90% this homework assignment on my own. I/We realize that it is a violation of academic integrity to share this work with others, either this semester, or after the class is over. I/We realize that the penalty for turning in work that is not my own, or assisting others in doing so, can range from an "F" in the class to dismissal from Trinity University Print Name Time Required =.

Assume Router Has Been Reset To Factory Specifications For The Following 7] {T/F} You are about to connect to the Linksys router for the first time. You must install special software to connect to the Linksys Router. 8] When first connecting to a Linksys Router (or after a reset) with a browser, you connect the browser to IP address _?_. 11] {T/F} A Router IP Address, which becomes the intranet gateway, must always remain ] The initial Linksys Router IP Address Linksys Router (or after a reset) is _?_.

3 DCN-Router-Configuration-HW.doc 3 CSCI ] Assume that the NIC card, above, is one of four computers connected to our router; it is set to A) To receive a an IP address from a router that issues DHCP addresses. B) To connect to our Linksys router with a static IP address. C) None of the above; it will not connect with to our router. 14] If the card above already has an IP address issued from a different network, it might be necessary to bring up a command box and enter _?_ to release the IP, DNS, SUBNET, and GATEWAY associated with that other network. (This would be faster than restarting the computer) 15] If the card above has released the IP address, it might be necessary to bring up a command box and enter _?_ to acquire a new IP, DNS, SUBNET, and GATEWAY from our router. (This would be faster than restarting the computer). 16] {T/F} The router above is configured to issue addresses to host clients. 17] The first IP address issued by the router configuration above would be 18] {T/F} Assume that router configuration above issues IP Address to one computer and another computer on the network has statically configured it s NIC card to use IP Address Both computers will be able to send and receive information, but it might be a bit slower. 19] Once we connect the CAT-5 from our NIC card shown above to the Linksys router, we should bring up a command window and enter _?_ to make sure that the router has issued us an IP ADDRESS, GATEWAY, & SUBNET.

4 DCN-Router-Configuration-HW.doc 4 CSCI ] B Once we confirm that our NIC card has IP = 150, SUBNET = , GATEWAY = from the Linksys Router, we can connect to the router with the router by entering IP Address in a B_?_. 21] When first connecting to a Linksys Router (or after a reset) the default password is _?_ and the User Name is blank. 22] {T/F} In order to connect to the newly configured Linksys Router, the router must either be configured for DHCP or have a gateway of ] Assume that the NIC card, above, is one of four computers connected to our router; it is set to A) To receive a an IP address from a router that issues DHCP addresses. B) To connect to our Linksys router with a static IP address. C) None of the above; it will not connect with to our router. 24] {T/F} The network card above is configured to connect to the reset Linksys Router.

B) To connect to our Linksys router with a static IP address. C) None of the above; it will not connect with to our router. 26] {T/F} If the DHCP component of our router is not functioning properly, the network card configuration above might enable us to connect to the reset Linksys Router. 27] {T/F} Entering IPCONFIG /Release in the command line will free the IP Address associated with the card above. 28] {T/F} It is possible for a router to properly issue an IP Address without properly providing DNS servers. 29] {T/F} It is possible for a router to properly issue an IP Address without properly providing DNS servers. 30] {T/F} Every network administrator should know one static IP address, outside his or her network, to ascertain whether the connection issues are for real or limited to DNS. (Carme is ). 31] {T/F} The reason that the network administrator should know one static IP Address outside his or her network, such as Carme = , is because PING requires DNS to function.

For security purposes, you should always place a router in between the ISP modem and your computer(s). 38] {T/F} The router acts as a hardware firewall between the Internet and your computer(s). 39] {T/F} Some Internet Service Providers make will provide a single box that acts as both a router and a modem. This provides a hardware firewall between the Internet and your computer(s). 40] {T/F} You should always enable the software firewall on your laptop before connecting to a public network of any type. 41] {T/F} It is ok to connect a laptop to Trinity s public network without your firewall enabled. 42] The snapshot of the window above is from the Linksys Router s _?_ tab.

8 DCN-Router-Configuration-HW.doc 8 CSCI ] One of the reasons that the IP Address, provided to the router by a Internet Service Provider via the cable modem, might be is because there is no _?_ that properly connects the cab le modem to your router. 44] {T/F} Some network providers, such as DSL, require that you use the provided UserName and Password in order to get an IP Adddress; this is generally done with a PPPoE Internet Connection. 45] {T/F} Some cable companies require that you use the provided UserName and Password in order to get an IP Adddress; this is generally done with a PPPoE Internet Connection. 46] One of the reasons that the IP Address, provided to the router by a Internet Service Provider via the cable modem, might be is because the _?_ and _?_ combination, required for PPPoE authentication, is incorrect. 47] If the Router s IP Address is and (1) the required authentication, if any, is correct and (2) the wires are plugged incorrectly, Dr. Hicks would suggest trying to push the _?_ button on the status tab. 48] If the Router s IP Address is and (1) the required authentication, if any, is correct and (2) the wires are plugged incorrectly, and (3) you have tried pushing the DHCP button, then, Dr. Hicks would suggest trying disconnecting the power to the Modem and the Router; then turn on the _?_ and wait until it powers up properly and then turn on the _?_.

The network administrator should make a written record of this configuration. 50] Examine the DHCP configuration, provided by your ISP, above. Write the DNS entries that you should record on you re the basic setup of the Setup Tab. Static DNS 1: Static DNS 2: Static DNS 3: 51] {T/F} Should our modem fail to provide DNS information to our router, at some later date, our systems will be able to use the DNS entries provided by our router. 52] {T/F} We should use the DNS entries, written above, for both static and dynamic router configurations.
