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.128 kb
• B.48 char
• C.32 character
• D.64 byte

Sandra is conducting a penetration test for XYZ.com. She knows that XYZ.com is using wireless networking for some of the offices in the building right down the street. Through social engineering she discovers that they are using 802.11g. Sandra knows that 802.11g uses the same 2.4GHz frequency range as 802.11b. Using NetStumbler and her 802.11b wireless NIC, Sandra drives over to the building to map the wireless networks. However, even though she repositions herself around the building several times, Sandra is not able to detect a single AP.
What do you think is the reason behind this?

• A.Netstumbler does not work against 802.11g.
• B.You can only pick up 802.11g signals with 802.11a wireless cards.
• C.802.11g uses OFDM while 802.11b uses DSSS so despite the same frequency and 802.11b card cannot see an 802.11g signal.
• D.The access points probably have disabled broadcasting of the SSID so they cannot be detected.
• E.Sandra must be doing something wrong,as there is no reason for her to not see the signals.
• F.The access points probably have WEP enabled so they cannot be detected.

The network administrator at Spears Technology, Inc has configured the default gateway Cisco router's access-list as below:

You are hired to conduct security testing on their network. You successfully brute-force the SNMP community string using a SNMP crack tool. The access-list configured at the router prevents you from establishing a successful connection. You want to retrieve the Cisco configuration from the router. How would you proceed?

• A.Run Generic Routing Encapsulation (GRE) tunneling protocol from your computer to the router masking your IP address
• B.Send a customized SNMP set request with a spoofed source IP address in the range 192.168.1.0
• C.Use the Cisco's TFTP default password to connect and download the configuration file
• D.Run a network sniffer and capture the returned traffic with the configuration file from the router

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

• A.Option D
• B.Option C
• C.Option B
• D.Option A

A network administrator received an administrative alert at 3:00 a.m. from the intrusion detection system. The alert was generated because a large number of packets were coming into the network over ports 20 and 21. During analysis, there were no signs of attack on the FTP servers. How should the administrator classify this situation?

• A.False negatives
• B.False positives
• C.True positives
• D.True negatives
