All these Questions are in this Section were asked in Certified Ethical Hacker Examinations of EC-Council .This is the 7th part


1- What tool should you use when you need to analyze extracted metadata from files you collected when you were in the initial stage of penetration test (information gathering)?

A. Armitage (GUI that visualizes targets and recommends exploits)
B. Dimitry (Deepmagic Information Gathering Tool)
C. Metagoofil

D. cdpsnarf (extract information from CDP packets)

Answer: C. Metagoofil

2- . What is the way to decide how a packet will move from an untrusted outside host to a protected inside that is behind a firewall, which permits the hacker to determine which ports are open and if the packets can pass through the packet-filtering of the firewall.

B. Session hijacking (exploit session to gain unauthorized access to information/service)
C. Man-in-the-middle attack (secretly relays and alters the communication between two parties)

What phase of the penetration test is the tester currently in?

A. Information reporting
B. Vulnerability assessment
C. Active information gathering
D. Passive information gathering

Answer: D. Passive information gathering
