Sorry, the question looks to be a real question from the exam. If it isn't I'm sorry. However the discussion on IIOP can continue.--Carl

May be I can help ;-)
First, there are only two options available for answer ;-)
Option D is obvious as correct answer
IIOP is connection-oriented unlike HTTP, where communication is performed in request-response model (open connection-send request-receive response-close connection). In IIOP virtual connection is maintained through the session, so there is no need to reestablish it over and over again with every new invokation, so the other correct option is B.
Second, for this question, not being secure means that data is being sent and received without involvement of the encryption, so basically anyone wo can get access to your packets and knows the potocol can access the data items being trnsmitted, unlike SSL for example, where communicaion is encrypted.
Hopefully this will help.

I agree with Mathew and Sergei about options B,D. Regarding the justification of Sergei i'd be careful on the statement HTTP "Its Connectionless", version 1.1 has incorporated the keep-alive feature which is a improvement to request-response model and it's based on keep a connection living along a session for several resquest-responses.
I have seen this question in some training tests just saying "HTTP" and i think the version of the protocol is important to figure it out.
