NEW QUESTION # 560

_______ for legal advice to defend them against this allegation.
Answer: A
Explanation:
In the context of legal allegations regarding the disclosure of personal information on a social networking site, a company would consult an attorney for legal advice. An attorney is a professional who is qualified to offer legal advice, represent clients in court, and defend them against legal claims. In this scenario, the attorney would help the company understand the legal implications of the allegations, advise on the best course of action, and provide representation if the case goes to court.
NEW QUESTION # 561
Which of the following standards is an amendment to the original IEEE 802.11 and specifies security mechanisms for wireless networks?
Answer: C
Explanation:
802.11i is an amendment to the original IEEE 802.11. This standard specifies security mechanisms for wireless networks. It replaced the short Authentication and privacy clause of the original standard with a detailed Security clause. In the process, it deprecated the broken WEP. 802.11i supersedes the previous security specification, Wired Equivalent Privacy (WEP), which was shown to have severe security weaknesses.
Wi-Fi Protected Access (WPA) had previously been introduced by the Wi-Fi Alliance as an intermediate solution to WEP insecurities. The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2, also called RSN (Robust Security Network). 802.11i makes use of the Advanced Encryption Standard (AES) block cipher, whereas WEP and WPA use the RC4 stream cipher.
Answer option D is incorrect. 802.11a is an amendment to the IEEE 802.11 specification that added a higher data rate of up to 54 Mbit/s using the 5 GHz band. It has seen widespread worldwide implementation, particularly within the corporate workspace. Using the 5 GHz band gives 802.11a a significant advantage, since the 2.4 GHz band is heavily used to the point of being crowded. Degradation caused by such conflicts can cause frequent dropped connections and degradation of service.
Answer option A is incorrect. 802.11b is an amendment to the IEEE 802.11 specification that extended throughput up to 11 Mbit/s using the same 2.4 GHz band. This specification under the marketing name of Wi-Fi has been implemented all over the world. 802.11b is used in a point-to-multipoint configuration, wherein an access point communicates via an omni-directional antenna with one or more nomadic or mobile clients that are located in a coverage area around the access point.
Answer option B is incorrect. The 802.11e standard is a proposed enhancement to the 802.11a and 802.11b wireless LAN (WLAN) specifications. It offers quality of service (QoS) features, including the prioritization of data, voice, and video transmissions. 802.11e enhances the 802.11 Media Access Control layer (MAC layer) with a coordinated time division multiple access (TDMA) construct, and adds error-correcting mechanisms for delay-sensitive applications such as voice and video.

NEW QUESTION # 564
Which of the following steps are required in an idle scan of a closed port?
Each correct answer represents a part of the solution. Choose all that apply.
Answer: B,C,D,E
Explanation:
Following are the steps required in an idle scan of a closed port:
1.Probe the zombie's IP ID: The attacker sends a SYN/ACK to the zombie. The zombie, unaware of the SYN/ ACK, sends back a RST, thus disclosing its IP ID.
2.Forge a SYN packet from the zombie: In response to the SYN, the target sends a RST. The zombie ignores the unsolicited RST, and the IP ID remains unchanged.
3.Probe the zombie's IP ID again: The zombie's IP ID has increased by only 1 since step 1. So the port is closed.
