  A. Fragmentation of packets.
  B. Use of only TCP based protocols.
  C. Use of only UDP based protocols.
  D. Use of fragmented ICMP traffic only.
  A. Fragmentation of packets.

• Question 933:

  A. non-repudiation.
  B. operability.

• Question 935:

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

• Question 936:

  Dan is conducting 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 scenario is incorrect as Dan can spoof his IP and get responses
  C. The server will send replies back to the spoofed IP address
  D. Dan can establish an interactive session only if he uses a NAT
  C. The server will send replies back to the spoofed IP address

• Question 937:

  Which of the following processes of PKI (Public Key Infrastructure) ensures that a trust relationship exists and that a certificate is still valid for specific operations?

  A. Certificate issuance
  B. Certificate validation
  C. Certificate cryptography
  D. Certificate revocation
  B. Certificate validation

• Question 938:

  What type of Virus is shown here?

  

  A. Macro Virus
  B. Cavity Virus
  C. Boot Sector Virus
  D. Metamorphic Virus
  E. Sparse Infector Virus
  B. Cavity Virus

• Question 939:

  WEP is used on 802.11 networks, what was it designed for?

  A. WEP is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what it usually expected of a wired LAN.
  B. WEP is designed to provide strong encryption to a wireless local area network (WLAN) with a lever of integrity and privacy adequate for sensible but unclassified information.
  C. WEP is designed to provide a wireless local area network (WLAN) with a level of availability and privacy comparable to what is usually expected of a wired LAN.
  D. WEOP is designed to provide a wireless local area network (WLAN) with a level of privacy comparable to what it usually expected of a wired LAN.
  A. WEP is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what it usually expected of a wired LAN.
