Q31. What attack is being depicted here?
A. Cookie Stealing
B. Session Hijacking
C. Cross Site scripting
D. Parameter Manipulation
Answer: D
Explanation: Manipulating the data sent between the browser and the web application to an attacker's advantage has long been a simple but effective way to make applications do things in a way the user often shouldn't be able to. In a badly designed and developed web application, malicious users can modify things like prices in web carts, session tokens or values stored in cookies and even HTTP headers. In this case the user has elevated his rights.
Q32. SSL has been seen as the solution to several common security problems. Administrators will often make use of SSL to encrypt communication from point A to point B. Why do you think this could be a bad idea if there is an Intrusion Detection System deployed to monitor the traffic between point A and B?
A. SSL is redundant if you already have IDS in place.
B. SSL will trigger rules at regular interval and force the administrator to turn them off.
C. SSL will slow down the IDS while it is breaking the encryption to see the packet content.
D. SSL will mask the content of the packet and Intrusion Detection System will be blinded.
Answer: D
Explanation: Because the traffic is encrypted, an IDS cannot understand it or evaluate the payload.
Q33. When working with Windows systems, what is the RID of the true administrator account?

Q34. You are the security administrator for a large network. You want to prevent attackers from running any sort of traceroute into your DMZ and discover the internal structure of publicly accessible areas of the network.
How can you achieve this?
A. Block ICMP at the firewall.
B. Block UDP at the firewall.
C. Both A and B.
D. There is no way to completely block doing a trace route into this area.
Answer: D
Explanation: When you run a traceroute to a target network address, you send a UDP packet with one time to live (TTL) to the target address. The first router this packet hits decreases the TTL to 0 and rejects the packet. Now the TTL for the packet is expired. The router sends back an ICMP message type 11 (Exceeded) code 0 (TTL--Exceeded) packet to your system with a source address. Your system displays the round-trip time for that first hop and sends out the next UDP packet with a TTL of 2.This process continues until you receive an ICMP message type 3 (Unreachable) code 3 (Port--Unreachable) from the destination system. Traceroute is completed when your machine receives a Port-Unreachable message.If you receive a message with three asterisks [* * *] during the traceroute, a router in the path doesn't return ICMP messages. Traceroute will continue to send UDP packets until the destination is reached or the maximum number of hops is exceeded.
Q35. If you send a SYN to an open port, what is the correct response?(Choose all correct answers.
A. SYN
B. ACK
C. FIN
D. PSH
Answer: AB
Explanation: The proper response is a SYN / ACK. This technique is also known as half-open scanning.
Q36. Which of the following is NOT a valid NetWare access level?
A. Not Logged in
B. Logged in

Q37. Travis works primarily from home as a medical transcriptions.
He just bought a brand new Dual Core Pentium Computer with over 3 GB of RAM. He uses voice recognition software is processor intensive, which is why he bought the new computer. Travis frequently has to get on the Internet to do research on what he is working on. After about two months of working on his new computer, he notices that it is not running nearly as fast as it used to.
Travis uses antivirus software, anti-spyware software and always keeps the computer up-to-date with Microsoft patches.
After another month of working on the computer, Travis computer is even more noticeable slow. Every once in awhile, Travis also notices a window or two pop-up on his screen, but they quickly disappear. He has seen these windows show up, even when he has not been on the Internet. Travis is really worried about his computer because he spent a lot of money on it and he depends on it to work. Travis scans his through Windows Explorer and check out the file system, folder by folder to see if there is anything he can find. He spends over four hours pouring over the files and folders and can’t find anything but before he gives up, he notices that his computer only has about 10 GB of free space available. Since has drive is a 200 GB hard drive, Travis thinks this is very odd.
Travis downloads Space Monger and adds up the sizes for all the folders and files on his computer. According to his calculations, he should have around 150 GB of free space. What is mostly likely the cause of Travi’s problems?
A. Travis’s Computer is infected with stealth kernel level rootkit
B. Travi’s Computer is infected with Stealth Torjan Virus
C. Travis’s Computer is infected with Self-Replication Worm that fills the hard disk space
D. Logic Bomb’s triggered at random times creating hidden data consuming junk files
Answer: A
Explanation: A rootkit can take full control of a system. A rootkit's only purpose is to hide files, network connections, memory addresses, or registry entries from other programs used by system administrators to detect intended or unintended special privilege accesses to the computer resources.
