EC-COUNCIL EC-Council Certified Network Defender CND Sample Questions (Q89-Q94):

NEW QUESTION # 89
Which of the following standards is an amendment to the original IEEE 802.11 and specifies security mechanisms for wireless networks?

A. 802.11a
B. 802.11b
C. 802.11e
D. 802.11i

Answer: D

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-tomultipoint 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 # 90
What is composite signature-based analysis?

A. Attack signatures are contained in packet headers
B. Single Packet analysis is enough to identify attack signatures
C. Attack signatures are contained in packet payloads
D. Multiple packet analysis is required to detect attack signatures

Answer: D

Explanation:
Composite signature-based analysis refers to a method of intrusion detection where multiple packets are analyzed to detect an attack signature. Unlike single-packet analysis, which may only require one packet to identify an attack, composite signature-based analysis looks for patterns across several packets to determine whether an attack is underway. This method is particularly useful for detecting complex attacks that cannot be identified by a single packet's header or payload alone.
References: The concept of composite signature-based analysis is part of the broader network defense strategy that includes protecting, detecting, responding, and predicting network security incidents. It aligns with the Certified Network Defender (CND) program's focus on understanding network traffic signatures and analysis as part of designing network security policies and incident response plans123.

NEW QUESTION # 91
Which antenna's characteristic refer to the calculation of radiated in a particular direction. It is generally the ratio of radiation intensity in a given direction to the average radiation intensity?

A. Radiation pattern
B. Polarization
C. Directivity
D. Typical gain

Answer: C

Explanation:
Directivity of an antenna refers to the measure of how concentrated the radiation emitted is in a single direction. It is defined as the ratio of the radiation intensity in a given direction from the antenna to the radiation intensity averaged over all directions. In simpler terms, it is the calculation of radiated power in a particular direction compared to the average radiated power in all directions. This characteristic is crucial for antennas designed to transmit or receive signals in a specific direction, making it an essential parameter for many communication systems.
References: The concept of directivity and its importance in antenna design is covered in the EC-Council's Certified Network Defender (CND) course materials, which include discussions on various antenna characteristics and their impact on network security12.

NEW QUESTION # 92
Which of the following is a distributed multi-access network that helps in supporting integrated communications using a dual bus and distributed queuing?

A. Distributed-queue dual-bus
B. CSMA/CA
C. Logical Link Control
D. Token Ring network

Answer: A

Explanation:
In telecommunication, a distributed-queue dual-bus network (DQDB) is a distributed multi-access network that helps in supporting integrated communications using a dual bus and distributed queuing, providing access to local or metropolitan area networks, and supporting connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications. IEEE 802.6 is an example of a network providing DQDB access methods. Answer option B is incorrect. A Token Ring network is a local area network (LAN) in which all computers are connected in a ring or star topology and a bit- or token-passing scheme is used in order to prevent the collision of data between two computers that want to send messages at the same time. The Token Ring protocol is the second most widely-used protocol on local area networks after Ethernet. The IBM Token Ring protocol led to a standard version, specified as IEEE
802.5. Both protocols are used and are very similar. The IEEE 802.5 Token Ring technology provides for data transfer rates of either 4 or 16 megabits per second. Answer option A is incorrect. The IEEE 802.2 standard defines Logical Link Control (LLC). LLC is the upper portion of the data link layer for local area networks. Answer option D is incorrect. Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) is an access method used by wireless networks (IEEE 802.11). In this method, a device or computer that transmits data needs to first listen to the channel for an amount of time to check for any activity on the channel. If the channel is sensed as idle, the device is allowed to transmit data. If the channel is busy, the device postpones its transmission. Once the channel is clear, the device sends a signal telling all other devices not to transmit data, and then sends its packets. In Ethernet (IEEE 802.3) networks that use CSMA/CD, the device or computer continues to wait for a time and checks if the channel is still free. If the channel is free, the device transmits packets and waits for an acknowledgment signal indicating that the packets were received.

NEW QUESTION # 93
Delta IT solutions suffered a substantial data loss translating into a huge monetary loss for them. While investigation, the network admin analyzed all the packets and traffic transmitted across the network and identified that some user, within the organization, had leaked the dat a. Which of the following devices could have helped the network admin reach this conclusion?

A. Network Access Control
B. Internet Content Filter
C. Network Protocol Analyzer
D. Intrusion Detection System

Answer: C

Explanation:
A Network Protocol Analyzer, such as Wireshark, is a tool that captures and analyzes packets in real-time, displaying them in a human-readable format. It allows network administrators to inspect individual packets deeply, which is essential for identifying and investigating data leaks within an organization. By examining the packet contents, the source and destination of the traffic, and other details, a Network Protocol Analyzer can help pinpoint the exact nature and origin of a data leak.
