Q411. Which of the following LM hashes represent a password of less than 8 characters? (Select 2) 

A. BA810DBA98995F1817306D272A9441BB 

B. 44EFCE164AB921CQAAD3B435B51404EE 

C. 0182BD0BD4444BF836077A718CCDF409 

D. CEC52EB9C8E3455DC2265B23734E0DAC 

E. B757BF5C0D87772FAAD3B435B51404EE 

F. E52CAC67419A9A224A3B108F3FA6CB6D 

Answer: BE

Explanation: Notice the last 8 characters are the same 

Q412. Which one of the following is defined as the process of distributing incorrect Internet Protocol (IP) addresses/names with the intent of diverting traffic? 

A. Network aliasing 

B. Domain Name Server (DNS) poisoning 

C. Reverse Address Resolution Protocol (ARP) 

D. Port scanning 

Answer: B

This reference is close to the one listed DNS poisoning is the correct answer. 

This is how DNS DOS attack can occur. If the actual DNS records are unattainable to the attacker for him to alter in this fashion, which they should be, the attacker can insert this data into the cache of there server instead of replacing the actual records, which is referred to as cache poisoning. 

Q413. What is the key advantage of Session Hijacking? 

A. It can be easily done and does not require sophisticated skills. 

B. You can take advantage of an authenticated connection. 

C. You can successfully predict the sequence number generation. 

D. You cannot be traced in case the hijack is detected. 

Answer: B

Explanation: As an attacker you don’t have to steal an account and password in order to take advantage of an authenticated connection. 

Q414. Bryce the bad boy is purposely sending fragmented ICMP packets to a remote target. The tool size of this ICMP packet once reconstructed is over 65,536 bytes. From the information given, what type of attack is Bryce attempting to perform? 

A. Smurf 

B. Fraggle 

C. SYN Flood 

D. Ping of Death 

Answer: D

Explanation: A ping of death (abbreviated "POD") is a type of attack on a computer that involves sending a malformed or otherwise malicious ping to a computer. A ping is normally 64 bytes in size (or 84 bytes when IP header is considered); many computer systems cannot handle a ping larger than the maximum IP packet size, which is 65,535 bytes. Sending a ping of this size can crash the target computer. Traditionally, this bug has been relatively easy to exploit. Generally, sending a 65,536 byte ping packet is illegal according to networking protocol, but a packet of such a size can be sent if it is fragmented; when the target computer reassembles the packet, a buffer overflow can occur, which often causes a system crash. 

Q415. Bob has a good understanding of cryptography, having worked with it for many years. Cryptography is used to secure data from specific threats but it does not secure the data from the specific threats but it does no secure the application from coding errors. It can provide data privacy; integrity and enable strong authentication but it can’t mitigate programming errors. What is a good example of a programming error that Bob can use to explain to the management how encryption will not address all their security concerns? 

A. Bob can explain that using a weak key management technique is a form of programming error 

B. Bob can explain that using passwords to derive cryptographic keys is a form of a programming error 

C. Bob can explain that a buffer overflow is an example of programming error and it is a common mistake associated with poor programming technique 

D. Bob can explain that a random number generation can be used to derive cryptographic keys but it uses a weak seed value and this is a form of a programming error 

Answer: C

Explanation: In computer security and programming, a buffer overflow, or buffer overrun, is a programming error which may result in a memory access exception and program termination, or in the event of the user being malicious, a possible breach of system security. 

Q416. What is a Trojan Horse? 

A. A malicious program that captures your username and password 

B. Malicious code masquerading as or replacing legitimate code 

C. An unauthorized user who gains access to your user database and adds themselves as a user 

D. A server that is to be sacrificed to all hacking attempts in order to log and monitor the hacking activity 

Answer: B

Explanation: A Trojan Horse is an apparently useful and innocent program containing additional hidden code which allows the unauthorized collection, exploitation, falsification, or destruction of data. 

Q417. _________ is a tool that can hide processes from the process list, can hide files, registry entries, and intercept keystrokes. 

A. Trojan 

B. RootKit 

C. DoS tool 

D. Scanner 

E. Backdoor 

Answer:

Explanation: Rootkits are tools that can hide processes from the process list, can hide files, registry entries, and intercept keystrokes. 

Q418. Password cracking programs reverse the hashing process to recover passwords.(True/False. 

A. True 

B. False 

Answer: B

Explanation: Password cracking programs do not reverse the hashing process. Hashing is a one-way process. What these programs can do is to encrypt words, phrases, and characters using the same encryption process and compare them to the original password. A hashed match reveals the true password. 

Q419. Ethereal works best on ____________. 

A. Switched networks 

B. Linux platforms 

C. Networks using hubs 

D. Windows platforms 

E. LAN's 

Answer: C

Explanation: Ethereal is used for sniffing traffic. It will return the best results when used on an unswitched (i.e. hub. network. 

Q420. What type of encryption does WPA2 use? 

A. DES 64 bit 

B. AES-CCMP 128 bit 

C. MD5 48 bit 

D. SHA 160 bit 

Answer: B
