Answer: A
Q107. Anonymizer sites access the Internet on your behalf, protecting your personal information from disclosure. An anonymizer protects all of your computer's identifying information while it surfs for you, enabling you to remain at least one step removed from the sites you visit.
You can visit Web sites without allowing anyone to gather information on sites visited by you. Services that provide anonymity disable pop-up windows and cookies, and conceal visitor's IP address.
These services typically use a proxy server to process each HTTP request. When the user requests a Web page by clicking a hyperlink or typing a URL into their browser, the service retrieves and displays the information using its own server. The remote server (where the requested Web page resides) receives information on the anonymous Web surfing service in place of your information.
In which situations would you want to use anonymizer? (Select 3 answers)
A. Increase your Web browsing bandwidth speed by using Anonymizer
B. To protect your privacy and Identity on the Internet
C. To bypass blocking applications that would prevent access to Web sites or parts of sites that you want to visit.
D. Post negative entries in blogs without revealing your IP identity
Answer: BCD
Q108. Bob has been hired to perform a penetration test on ABC.com. He begins by looking at IP address ranges owned by the company and details of domain name registration. He then goes to News Groups and financial web sites to see if they are leaking any sensitive information of have any technical details online.
Within the context of penetration testing methodology, what phase is Bob involved with?
A. Passive information gathering
B. Active information gathering
C. Attack phase
D. Vulnerability Mapping
Answer: A
Explanation: He is gathering information and as long as he doesn’t make contact with any of the targets systems he is considered gathering this information in a passive mode.
Q109. ou wish to determine the operating system and type of web server being used. At the same time you wish to arouse no suspicion within the target organization.

B. Use nmap in paranoid mode and scan the web server.
C. Telnet to the web server and issue commands to illicit a response.
D. Use the netcraft web site look for the target organization’s web site.
Answer: D
Explanation: Netcraft is providing research data and analysis on many aspects of the Internet. Netcraft has explored the Internet since 1995 and is a respected authority on the market share of web servers, operating systems, hosting providers, ISPs, encrypted transactions, electronic commerce, scripting languages and content technologies on the internet.
Q110. The SNMP Read-Only Community String is like a password. The string is sent along with each SNMP Get-Request and allows (or denies) access to a device. Most network vendors ship their equipment with a default password of "public". This is the so-called "default public community string". How would you keep intruders from getting sensitive information regarding the network devices using SNMP? (Select 2 answers)
A. Enable SNMPv3 which encrypts username/password authentication
B. Use your company name as the public community string replacing the default 'public'
C. Enable IP filtering to limit access to SNMP device
D. The default configuration provided by device vendors is highly secure and you don't need to change anything
Answer: AC
Q111. If a competitor wants to cause damage to your organization, steal critical secrets, or put you out of business, they just have to find a job opening, prepare someone to pass the interview, have that person hired, and they will be in the organization.
How would you prevent such type of attacks?
A. It is impossible to block these attacks
B. Hire the people through third-party job agencies who will vet them for you
C. Conduct thorough background checks before you engage them
D. Investigate their social networking profiles
Answer: C
Q112. Dan is conducting a penetration testing and has found a vulnerability in a Web Application which gave him the sessionID token via a cross site scripting vulnerability. Dan wants to replay this token. However, the session ID manager (on the server) checks the originating IP address as well. Dan decides to spoof his IP address in order to replay the sessionID. Why do you think Dan might not be able to get an interactive session?
A. Dan cannot spoof his IP address over TCP network
B. The server will send replies back to the spoofed IP address
C. Dan can establish an interactive session only if he uses a NAT
D. The scenario is incorrect as Dan can spoof his IP and get responses
Answer: B
Explanation: Spoofing your IP address is only effective when there is no need to establish a two way connection as all traffic meant to go to the attacker will end up at the place of the spoofed address.
Q113. What are two things that are possible when scanning UDP ports? (Choose two.
A. A reset will be returned
B. An ICMP message will be returned
C. The four-way handshake will not be completed
D. An RFC 1294 message will be returned
E. Nothing
Answer: BE
Explanation: Closed UDP ports can return an ICMP type 3 code 3 message. No response can mean the port is open or the packet was silently dropped.
Q114. Bret is a web application administrator and has just read that there are a number of surprisingly common web application vulnerabilities that can be exploited by unsophisticated attackers with easily available tools on the Internet.
He has also read that when an organization deploys a web application, they invite the world to send HTTP requests. Attacks buried in these requests sail past firewalls, filters, platform hardening, SSL, and IDS without notice because they are inside legal HTTP requests. Bret is determined to weed out any vulnerabilities. What are some common vulnerabilities in web applications that he should be concerned about?
A. Non-validated parameters, broken access control, broken account and session management, cross-side scripting and buffer overflows are just a few common vulnerabilities
B. No IDS configured, anonymous user account set as default, missing latest security patch, no firewall filters set and visible clear text passwords are just a few common vulnerabilities
C. Visible clear text passwords, anonymous user account set as default, missing latest security patch, no firewall filters set and no SSL configured are just a few common vulnerabilities
D. No SSL configured, anonymous user account set as default, missing latest security patch, no firewall filters set and an inattentive system administrator are just a few common vulnerabilities
Answer: A

Answer: C
Q116. What is the proper response for a NULL scan if the port is open?
A. SYN
B. ACK
C. FIN
D. PSH
E. RST

Q117. Which of the following represents the initial two commands that an IRC client sends to join an IRC network?
A. USER, NICK
B. LOGIN, NICK
C. USER, PASS

Q118. Jim is having no luck performing a penetration test in company’s network. He is running the tests from home and has downloaded every security scanner that he could lay his hands on. Despite knowing the IP range of all the systems, and the exact network configuration, Jim is unable to get any useful results.
Why is Jim having these problems?
A. Security scanners are not designed to do testing through a firewall.
B. Security scanners cannot perform vulnerability linkage.
C. Security scanners are only as smart as their database and cannot find unpublished vulnerabilities.
D. All of the above.
Answer: D
Explanation: The Security scanners available online are often to “outdated” to perform a live pentest against a victim.
Q119. A common technique for luring e-mail users into opening virus-launching attachments is to send messages that would appear to be relevant or important to many of their potential recipients. One way of accomplishing this feat is to make the virus-carrying messages appear to come from some type of business entity retailing sites, UPS, FEDEX, CITIBANK or a major provider of a common service.
Here is a fraudulent e-mail claiming to be from FedEx regarding a package that could not be delivered. This mail asks the receiver to open an attachment in order to obtain the FEDEX tracking number for picking up the package. The attachment contained in this type of e-mail activates a virus.
Vendors send e-mails like this to their customers advising them not to open any files attached with the mail, as they do not include attachments.
Fraudulent e-mail and legit e-mail that arrives in your inbox contain the fedex.com as the sender of the mail.
How do you ensure if the e-mail is authentic and sent from fedex.com?
A. Verify the digital signature attached with the mail, the fake mail will not have Digital ID at all
B. Check the Sender ID against the National Spam Database (NSD)
C. Fake mail will have spelling/grammatical errors
D. Fake mail uses extensive images, animation and flash content
Answer: A
