Question on server Ports

[Pooja Chetty]

In one of the mock exam i came across the question in server ports. The question is as below

Q: You work as a software Developer for UcTech Inc. You write a request zand send it to a remote address as follows

1. The client abc.def.ghi sends the request . The port numbe of the client is 20.0.1.7
2. The request was sent to a port number 25.0.1.7. The request ended on port 25.0.1.8


Drag and drop the appropriate methods that you will use to retrive the address and port number of the client and server with the following port number and addresses.

Column A Column B

20.0.1.7 getRemoteHost()
25.0.1.7 getServerPort()
abc.def.ghi getLocalPort()
25.0.1.8 getRemotePort()
getRemoteClient()

Will i get Questions of this kind on server ports in the exam(SCWCD 1.4). If so could anyone please suggest the material i need to go through. I have my exam scheduled next week.


Thanks in advance
Pooja

For questions like these, you need to QuoteYourSources, please. "One of the mock exams" is not sufficient.

The whole question sounds odd, since something like "20.0.1.17" is not a port number, but an IP address.

That question i stated above is from uCertify PrepEngine demo version Simulator.

I want to know whether these kind of questions will appear in the SCWCD 1.4 Exam.

getRemotePort() -- returns the port of the client that sent the request -- in this case it is 20.0.1.7

getRemoteHost() -- Returns the fully qualified name of the client that sent the request, which in this case will be "abc.def.ghi"

getServerPort() -- to which port was the request originally sent? , in this case it is 25.0.1.7

getLocalPort() -- where the request ended up -- in this case '25.0.1.8"
