• Question 371:

  You are writing security policy that hardens and prevents Footprinting attempt by Hackers.

  Which of the following countermeasures will NOT be effective against this attack?

  A. Configure routers to restrict the responses to Footprinting requests

  B. Configure Web Servers to avoid information leakage and disable unwanted protocols

  C. Lock the ports with suitable Firewall configuration

  D. Use an IDS that can be configured to refuse suspicious traffic and pick up Footprinting patterns

  E. Evaluate the information before publishing it on the Website/Intranet

  F. Monitor every employee computer with Spy cameras,keyloggers and spy on them

  G. Perform Footprinting techniques and remove any sensitive information found on DMZ sites

  H. Prevent search engines from caching a Webpage and use anonymous registration services

  I. Disable directory and use split-DNS

  Correct Answer: F

• Question 372:

  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

  Correct Answer: AC

• Question 373:

  What do you call a pre-computed hash?

  A. Sun tables

  B. Apple tables

  C. Rainbow tables

  D. Moon tables

  Correct Answer: C

• Question 374:

  Why attackers use proxy servers?

  A. To ensure the exploits used in the attacks always flip reverse vectors

  B. Faster bandwidth performance and increase in attack speed

  C. Interrupt the remote victim's network traffic and reroute the packets to attackers machine

  D. To hide the source IP address so that an attacker can hack without any legal corollary

  Correct Answer: D

• Question 375:

  What command would you type to OS fingerprint a server using the command line?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C

• Question 376:

  Which type of password cracking technique works like dictionary attack but adds some numbers and symbols to the words from the dictionary and tries to crack the password?

  A. Dictionary attack

  B. Brute forcing attack

  C. Hybrid attack

  D. Syllable attack

  E. Rule-based attack

  Correct Answer: C

• Question 377:

  You generate MD5 128-bit hash on all files and folders on your computer to keep a baseline check for security reasons?

  

  What is the length of the MD5 hash?

  A. 32 character

  B. 64 byte

  C. 48 char

  D. 128 kb

  Correct Answer: A

• Question 378:

  Bill is a security analyst for his company. All the switches used in the company's office are Cisco switches. Bill wants to make sure all switches are safe from ARP poisoning.

  How can Bill accomplish this?

  A. Bill can use the command: ip dhcp snooping.

  B. Bill can use the command: no ip snoop.

  C. Bill could use the command: ip arp no flood.

  D. He could use the command: ip arp no snoop.

  Correct Answer: A

• Question 379:

  NTP allows you to set the clocks on your systems very accurately, to within 100ms and sometimes-even 10ms. Knowing the exact time is extremely important for enterprise security. Various security protocols depend on an accurate source of time information in order to prevent "playback" attacks. These protocols tag their communications with the current time, to prevent attackers from replaying the same communications, e.g., a login/password interaction or even an entire communication, at a later date. One can circumvent this tagging, if the clock can be set back to the time the communication was recorded. An attacker attempts to try corrupting the clocks on devices on your network. You run Wireshark to detect the NTP traffic to see if there are any irregularities on the network.

  What port number you should enable in Wireshark display filter to view NTP packets?

  A. TCP Port 124

  B. UDP Port 125

  C. UDP Port 123

  D. TCP Port 126

  Correct Answer: C

• Question 380:

  Jane wishes to forward X-Windows traffic to a remote host as well as POP3 traffic. She is worried that adversaries might be monitoring the communication link and could inspect captured traffic. She would like to tunnel the information to the remote end but does not have VPN capabilities to do so.

  Which of the following tools can she use to protect the link?

  A. MD5

  B. PGP

  C. RSA

  D. SSH

  Correct Answer: D
