5. Your SOHO router has failed and you have installed a new router. The old router’s static IP address on the network is 192.168.0.1. The new router has a static IP address of 10.0.0.1. You go to a computer to configure the new router and enter 10.0.0.1 in the browser address box. The router does not respond. You open a command prompt window and try to ping the router, which does not work. Next, you verify that the router has connectivity and you see that its local connection light is blinking, indicating connectivity. What is the most likely problem and its best solution?

Group of answer choices

The computer you are using to configure the router has a corrupted TCP/IP configuration. Restart the computer.

The router is defective. Return it for a full refund.

The computer and the router are not in the same subnet. Release and renew the IP address of the computer.

The computer and the router are not in the same subnet. Change the subnet mask assigned to the computer.

Question 8

Your boss asks you to transmit a small file that includes sensitive personnel data to a server on the network. The server is running a Telnet server and an FTPS server. Why is it not a good idea to use Telnet to reach the remote computer?

Group of answer choices

Telnet transmissions are not encrypted.

Telnet is not reliable and the file might arrive corrupted.

FTP is faster than Telnet.

FTP running on the same computer as Telnet causes Telnet not to work.

25 and 110

Answer 1

1. TCP this is the protocol that ensures the transmission is 100% done.

2.Cable tested is a device which is used to check whether the connection is good or not.

3. MAC Address because switch is an intelligent device which only transmits the data for that computer where the data wants to send and the reason that switch send that data to that switch has a MAC address table where it store the MAC address of all computers so that for future transmission the data want to sent only that perticular computer only.

4. The two ip address are in intranet are 192.168.2.143 //255.255.255.0 and 192.168.5.57 //255.255.255.0 and the remain two are not because of the intranet content of ip range from 192.168.0.0 to 192.168.255.255 and for the 172 range from the 172.16.0.0 to 172.31.255.255 so the ip address remains two are not in private ip address which we give in our intranet address so. The two Ans are from 192.168 ranges.

5.The computer and the router are not in the same subnet. Release and renew the IP address of the computer. This is answer because router has static ip address and the computer has different ip address so they were not in same mask.

6.false because telnet protocol not use the encryption method when the data transmitting over the Internet for security it not provide any encryption when data sent it only in plain text.

7.110,25 Smtp and pop are the protocol that are used for sent and received that data and the port no of POP is 110 and Smtp has port no 25.

8. Telnet transmission are not encrypted and because of this reason it not provide the security to the sensetive data but in the case of FTPS server it use ssh which is more reliable secure and so it is better to use FTPS.

9.TIA/EIA 586 is the standard which is used for the connection of RJ-45 connector this is and standered code for data flow connection.

10.tracert is the command that is use for check the hop to destination it show all of hop which is reaching.

11.True the punch down tool is used for seating the wire in RJ-45 in there jack.

12. Switch this is device which has MAC address table which store that MAC addresses of all the computers for any kind of transmission switch use that MAC table.

13. 22 is port that use SSH remote login protocol which listening all connection.

14.POP3 and IMAP4 are the two protocol which use for receive mails.

15. There is no image provided

16. True because phone cords are use cat3 twisted pair of wires which is provide connection through RJ-45 connectors.

17.you need to filters on every phone jack this is true about cable which provide connectivity of Internet.

18.crossover cable and straight through cable are the two cable that is used when you have to connection with any networking devices and also with computer connection this two network cable connection is required.

19.100BASE-FX this fibre optic cable has capability to tanfer data with speed of 100mbps.

20.587 and 993 thus two are the ports have secured connection IMAP4 have 993 port number and SMTP has the secure port number 587.
