system development using 4GLs?
A. Inadequate screen/report design facilities
B. Complex programming language subsets
C. Lack of portability across operating systems
D. Inability to perform data intensive operations

C. Structured walk-through
D. Design and code
Answer: A

A blackbox test is a dynamic analysis tool for testing software modules. During the testing
of software modules a blackbox test works first in a cohesive manner as one single
unit/entity, consisting of numerous modules and second, with the user data that flows
across software modules. In some cases, this even drives the software behavior.
Question No : 4 - (Topic 1)
Which of the following is MOST likely to result from a business process reengineering
(BPR) project?
A. An increased number of people using technology
B. Significant cost savings, through a reduction in the complexity of information technology
C. A weaker organizational structures and less accountability
D. Increased information protection (IP) risk will increase
Answer: A
Explanation:
A BPR project more often leads to an increased number of people using technology, and
this would be a cause for concern. Incorrect answers:
B. As BPR is often technology oriented, and this technology is usually more complex and
volatile than in the past, cost savings do not often materialize in this areA.
D. There is no reason for IP to conflict with a BPR project, unless the project is not run
properly.

Explanation:
A bridge connects two separate networks to form a logical network (e.g., joining an
ethernet and token network) and has the storage capacity to store frames and act as a
storage and forward device. Bridges operate at the OSI data link layer by examining the
media access control header of a data packet.
Question No : 6 - (Topic 1)
Which of the following is a benefit of using callback devices?
A. Provide an audit trail
B. Can be used in a switchboard environment
C. Permit unlimited user mobility
D. Allow call forwarding
Answer: A
Explanation:
A callback feature hooks into the access control software and logs all authorized and
unauthorized access attempts, permitting the follow-up and further review of potential
breaches. Call forwarding (choice D) is a means of potentially bypassing callback control.
By dialing through an authorized phone number from an unauthorized phone number, a
perpetrator can gain computer access. This vulnerability can be controlled through callback
systems that are available.
Question No : 7 - (Topic 1)
A call-back system requires that a user with an id and password call a remote server
through a dial-up line, then the server disconnects and:

number from its database.
B. dials back to the user machine based on the user id and password using a telephone
number provided by the user during this connection.
C. waits for a redial back from the user machine for reconfirmation and then verifies the
user id and password using its database.
D. waits for a redial back from the user machine for reconfirmation and then verifies the
user id and password using the sender's database.
