ECCouncil Network Defense Essentials (NDE) Exam Sample Questions (Q60-Q65):

NEW QUESTION # 60
Kalley, a network administrator of an organization, has installed a traffic monitoring system to capture and report suspicious traffic signatures. In this process, she detects traffic containing password cracking, sniffing, and brute-forcing attempts.Which of the following categories of suspicious traffic signature were identified by Kalley through the installed monitoring system?

A. Reconnaissance signatures
B. Denial-of-service (DoS) signatures
C. Informational signatures
D. Unauthorized access signatures

Answer: D

Explanation:
Unauthorized access signatures were identified by Kalley through the installed monitoring system.
Unauthorized access signatures are designed to detect attempts to gain unauthorized access to a system or network by exploiting vulnerabilities, misconfigurations, or weak credentials. Password cracking, sniffing, and brute-forcing are common techniques used by attackers to obtain or guess the passwords of legitimate users or administrators and gain access to their accounts or privileges. These techniques generate suspicious traffic patterns that can be detected by traffic monitoring systems, such as Snort, using signature-based detection.
Signature-based detection is based on the premise that abnormal or malicious network traffic fits a distinct pattern, whereas normal or benign traffic does not. Therefore, by installing a traffic monitoring system and capturing and reporting suspicious traffic signatures, Kalley can identify and prevent unauthorized access attempts and protect the security of her organization's network.References:

NEW QUESTION # 61
Robert, an ISP, was instructed to provide network connectivity to all areas even if some locations are inaccessible to capture direct signals from wireless access points. In this process, Robert used a wireless network component that takes a signal from one access point and boosts its signal strength to create a new network.
Identify the component of the wireless network employed by Robert in the above scenario.

A. Mobile hotspot
B. Wireless bridge
C. Wireless NIC
D. Wireless repeater

Answer: D

Explanation:
A wireless repeater is a wireless network component that takes a signal from one access point and boosts its signal strength to create a new network. A wireless repeater can extend the range of a wireless network by repeating the signal from the original access point. This way, the wireless repeater can provide network connectivity to areas that are inaccessible to capture direct signals from the access point.In the scenario, Robert used a wireless repeater to provide network connectivity to all areas12.References:Network Defense Essentials - EC-Council Learning,Understanding the Wireless Network Components

NEW QUESTION # 62
Identify the backup mechanism that is performed within the organization using external devices such as hard disks and requires human interaction to perform the backup operations, thus, making it suspectable to theft or natural disasters.

A. Cloud data backup
B. Offsite data backup
C. Online data backup
D. Onsite data backup

Answer: D

Explanation:
Onsite data backup is the backup mechanism that is performed within the organization using external devices such as hard disks and requires human interaction to perform the backup operations, thus, making it susceptible to theft or natural disasters. Onsite data backup means storing the backup data on a local storage device, such as an external hard drive, a USB flash drive, a CD/DVD, or a tape drive, that is physically located in the same premises as the original data source. Onsite data backup has some advantages, such as fast backup and restore speed, easy access, and low cost. However, it also has some disadvantages, such as requiring manual intervention, occupying physical space, and being vulnerable to damage, loss, or theft. If a disaster, such as a fire, flood, earthquake, or power outage, occurs in the organization, both the original data and the backup data may be destroyed or inaccessible. Therefore, onsite data backup is not a reliable or secure way to protect the data from unforeseen events.References:

NEW QUESTION # 63
George, a professional hacker, targeted a bank employee and tried to crack his password while he was attempting to log on to the remote server to perform his regular banking operations. In thisprocess, George used sniffing tools to capture the password pairwise master key (PMK) associated with the handshake authentication process. Then, using the PMK, he gained unauthorized access to the server to perform malicious activities.
Identify the encryption technology on which George performed password cracking.

A. WEP
B. WPA2
C. WPA3
D. WPA

Answer: B

Explanation:
WPA2 (Wi-Fi Protected Access 2) is an encryption technology that secures wireless networks using the IEEE
802.11i standard. WPA2 uses a four-way handshake to authenticate the client and the access point, and to generate a pairwise transient key (PTK) for encrypting the data. The PTK is derived from the password pairwise master key (PMK), which is a shared secret between the client and the access point. The PMK can be obtained either by using a pre-shared key (PSK) or by using an 802.1X authentication server. In the above scenario, George performed password cracking on WPA2, as he used sniffing tools to capture the PMK associated with the handshake authentication process. Then, using the PMK, he was able to derive the PTK and decrypt the data exchanged between the client and the access point.References:

NEW QUESTION # 64
Which of the following practices helps security professionals protect mobile applications from various attacks?

A. Allow apps to save passwords to avoid multiple logins
B. Use containerization for critical corporate data
C. Use query string while handling sensitive data
D. Always cache app data

Answer: B

Explanation:
Containerization is a practice that helps security professionals protect mobile applications from various attacks. Containerization is a technique that isolates critical corporate data from the rest of the device data and applications. Containerization creates a secure and encrypted environment on the device where the corporate data and applications can be accessed and managed.This way, containerization prevents unauthorized access, data leakage, malware infection, or device theft from compromising the corporate data and applications12.References:Network Defense Essentials - EC-Council Learning,Mobile Application Security:
