What is the port number for (File Transfer Protocol – Data) FTP? Correct Answer 20

The correct answer is option 2.

Concept:

File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client-server model architecture using separate control and data connections between the client and the server.

Port numbers 21 and 20 are used for FTP. Port 21 is used to establish the connection between the 2 computers (or hosts) and port 20 to transfer data (via the Data channel).

Port 20- Data

Port 21- Host

File transfer is among the most frequently used TCP/IP applications and it accounts for a lot of the network traffic on the Internet. Various standard file transfer protocols existed even before the Internet was available to everyone and it was these early versions of the file transfer software that helped create today's standard known as the File Transfer Protocol (FTP).

Hence the correct answer is 20.

In each question below is given a statement numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the following assumption and decide which of the assumption is implicit in the statement. Statement: Every time Sri Lanka’s president, Mahinda Rajapaksa, turned to his Chinese allies for loans and assistance with an ambitious port project, the answer was yes. Yes, though feasibility studies said the port wouldn’t work. Yes, though other frequent lenders like India had refused. Yes, though Sri Lanka’s debt was ballooning rapidly under Rajapaksa.  Assumptions: I. China had a stake in Sri Lanka’s main port as well, China Harbor was building a new terminal there, known at the time as Colombo Port City. Along with that deal came roughly 50 acres, solely held by the Chinese company, where Sri Lanka had no sovereignty.  II. Sri Lankan officials are quick to point out that the agreement explicitly rules out China’s military use of the site. But others also note that Sri Lanka’s government, still heavily indebted to China, could be pressured to allow it.  III. The rising debt and project costs, even as the port was struggling, handed Sri Lanka’s political opposition a powerful issue, and it campaigned heavily on suspicions about China. Rajapaksa may lose the election.

Consider the following three statements about link state and distance vector routing protocols, for a large network with 500 network nodes and 4000 links. [S1] The computational overhead in link state protocols is higher than in distance vector protocols.
