A telecommunications company, XYZ , is building an enterprise system to allow the XYZ support staff to access customer information over an intranet. All of the customer information is stored in a legacy system and can only be accessed using a VT100 terminal session. You must create an architecture to access the legacy system. What should you use to encapsulate access to the legacy system?

A) A JDBC connection that uses SQL to query the legacy system.
B) AN EJB entity bean that uses JMS to interact with the legacy system.
C) A distributed CORBA object that uses IIOP to interact with the legacy system.
D) An EJB session bean that uses a screen-scraping tool to interact with the legacy system.

I Answered D because of statement "can only be accessed...."
But the answer given is A.

Can you help???

Hi Amol,

I agree with you.
This question was bad constructed.
