Eccouncil ECSAv10 Exam - Topic 2 Question 17 Discussion

Actual exam question for Eccouncil's ECSAv10 exam

Question #: 17
Topic #: 2

Transmission control protocol accepts data from a data stream, divides it into chunks, and adds a TCP header creating a TCP segment. The TCP header is the first 24 bytes of a TCP segment that contains the parameters and state of an end-to-end TCP socket. It is used to track the state of communication between two TCP endpoints.

For a connection to be established or initialized, the two hosts must synchronize. The synchronization requires each side to send its own initial sequence number and to receive a confirmation of exchange in an acknowledgment (ACK) from the other side

The below diagram shows the TCP Header format:

A16 bits

B32 bits

C8 bits

D24 bits

I thought it was 32 bits, but I guess I was wrong.

Wait, is it really 24 bits? I thought it was more.

TCP header is 24 bytes, right?

I remember the TCP header being 24 bits, but I also thought there were some 16-bit fields in there. This is tricky!

I feel like I might be mixing up the sizes. Was it 16 bits or 32 bits? I can't recall the exact details from my notes.

I practiced a similar question about TCP segments last week, and I believe the header is actually 24 bits. That sounds right to me.

I think the TCP header is 32 bits, but I'm not entirely sure. I remember something about it being related to the sequence numbers.

Hmm, this looks like it's testing my knowledge of the USERENV namespace. I'll need to think carefully about which value doesn't change during a session.

This seems like a straightforward question. I'd go with option B - saving their work to a shared folder on the network. That seems like the quickest and most efficient way to collect all the presentations.

In my opinion, Kelley might be right about the agency cost part, as using leverage can indeed help align interests, but I'm not entirely confident about his claims regarding the trade-off theory.

This is a tricky one. I'll need to think carefully about the different options and how they relate to data protection legislation.

I'm confident the answer is B. The code simply evaluates the expression `5` and returns the result.
