proprietary web application before launch. Which of the following is the penetration tester MOST likely to use while performing black box testing of the security of the company’s purchased
application? (Select TWO).
Correct Answer:
CD
C: Local proxy will work by proxying traffic between the web client and the web server. This is a tool that can be put to good effect in this case.
D: Fuzzing is another form of blackbox testing and works by feeding a program multiple input iterations that are specially written to trigger an internal error that might indicate a bug and crash it. Incorrect Answers:
A: A Code review refers to the examination of an application (the new HTML5 application in this case) that is designed to identify and assess threats to the organization. But this is not the most likely test to be carried out when performing black box testing.
B: Application sandboxing refers to the process of writing files to a temporary storage are (the socalled sandbox) so that you limit the ability of possible malicious code to execute on your computer.
E: Port scanning is used to scan TCP and UDP ports and report on their status. You can thus determine which services are running on a targeted computer.

An educational institution would like to make computer labs available to remote students. The labs are used for various IT networking, security, and programming courses. The requirements are: Each lab must be on a separate network segment.
Labs must have access to the Internet, but not other lab networks.
Student devices must have network access, not simple access to hosts on the lab networks. Students must have a private certificate installed before gaining access.
Servers must have a private certificate installed locally to provide assurance to the students. All students must use the same VPN connection profile.
Which of the following components should be used to achieve the design in conjunction with directory services?
Correct Answer:
C
IPSec VPN with mutual authentication meets the certificates requirements. RADIUS can be used with the directory service for the user authentication.
