EC-COUNCIL EC-Council Certified Network Defender CND Sample Questions (Q316-Q321):

NEW QUESTION # 316
Frank installed Wireshark at all ingress points in the network. Looking at the logs he notices an odd packet source. The odd source has an address of 1080:0:FF:0:8:800:200C:4171 and is using port 21. What does this source address signify?

A. This source address signifies that the originator is using 802dot1x to try and penetrate into Frank's network
B. This source address is IPv6 and translates as 13.1.68.3
C. This means that the source is using IPv4
D. This address means that the source is using an IPv6 address and is spoofed and signifies an IPv4 address of 127.0.0.1.

Answer: D

Explanation:
The address 1080:0:FF:0:8:800:200C:4171 is an IPv6 address. IPv6 addresses are 128-bit identifiers for interfaces and sets of interfaces. In this case, the address includes a block ::FFFF: (or 0:FF), which is a reserved subnet prefix to facilitate IPv4 to IPv6 migration. This is known as an IPv4-mapped IPv6 address. It is used to represent an IPv4 address in an IPv6 address format. The last 32 bits of the address represent an IPv4 address, which in this case corresponds to 127.0.0.1 - the loopback address in IPv4 used to establish an IP connection to the same machine or computer being used by the end-user.
References: The explanation is based on standard IPv6 addressing rules and the specific structure of IPv4-mapped IPv6 addresses. The information is consistent with the ECCouncil's Network Defender (CND) course objectives regarding understanding and analyzing network protocols and addressing12.

NEW QUESTION # 317
A network administrator is monitoring the network traffic with Wireshark. Which of the following filters will she use to view the packets moving without setting a flag to detect TCP Null Scan attempts?

A. Tcp.flags==0X029
B. TCRflags==0x000
C. Tcp.dstport==7
D. Tcp.flags==0x003

Answer: B

Explanation:
In Wireshark, to detect TCP Null Scan attempts, the filter used is tcp.flags==0. This filter will show packets where no TCP flags are set, which is indicative of a TCP Null Scan. A TCP Null Scan is a type of network reconnaissance technique where the attacker sends TCP packets with no flags set to the target system. If the target system responds with a RST packet, it indicates that the port is closed, while no response suggests that the port is open or filtered. This method is used because some systems do not log these null packets, allowing the scan to go unnoticed.
References: The information provided is based on standard network security practices for monitoring and analyzing network traffic using Wireshark, as well as the specific details of TCP Null Scans and their detection as outlined in network security resources1.

NEW QUESTION # 318
Mark is monitoring the network traffic on his organization's network. He wants to detect a TCP and UDP ping sweep on his network. Which type of filter will be used to detect this on the network?

A. Tcp.dstport==7 and udp.dstport==7
B. Tcp.srcport==7 and udp.srcport==7
C. Tcp.srcport==7 and udp.dstport==7
D. Tcp.dstport==7 and udp.srcport==7

Answer: A

Explanation:
To detect TCP and UDP ping sweeps on a network, the appropriate filter would be one that checks for packets directed at port 7, which is commonly used for the 'echo' service. This service is associated with ping functionality for both TCP and UDP protocols. Therefore, the correct filter to use would be Tcp.dstport==7 and udp.dstport==7, which checks for incoming packets where the destination port is 7 for both TCP and UDP traffic. This allows Mark to identify ping sweep attempts, as these would typically send packets to this port to elicit a response from the network.
References: The Certified Network Defender (CND) course material outlines the importance of understanding and utilizing network filters to detect various types of network scans and sweeps, including TCP and UDP ping sweeps1. This is further supported by industry practices and discussions on network security monitoring and defense1.

NEW QUESTION # 319
According to the company's security policy, all access to any network resources must use Windows Active Directory Authentication. A Linux server was recently installed to run virtual servers and it is not using Windows Authentication. What needs to happen to force this server to use Windows Authentication?

A. Edit the shadow file.
B. Edit the PAM file to enforce Windows Authentication
C. Edit the ADLIN file.
D. Remove the /var/bin/localauth.conf file.

Answer: B

Explanation:
To enforce Windows Active Directory Authentication on a Linux server, the Pluggable Authentication Modules (PAM) configuration files must be edited. PAM provides a way to develop programs that are independent of authentication scheme. These files, located in /etc/pam.d/, dictate how a Linux system handles authentication for various services. To integrate Windows Active Directory with a Linux server, specific PAM modules like pam_krb5 or pam_winbind can be used. These modules allow the Linux system to communicate with the Active Directory server for authentication purposes. The process typically involves installing necessary packages, joining the Linux server to the AD domain, and configuring the PAM files to use AD for authentication.

NEW QUESTION # 320
Which of the following is a standard protocol for interfacing external application software with an information server, commonly a Web server?

A. DHCP
B. IP
C. CGI
D. TCP

Answer: C

Explanation:
The Common Gateway Interface (CGI) is a standard protocol for interfacing external application software with an information server, commonly a Web server. The task of such an information server is to respond to requests (in the case of web servers, requests from client web browsers) by returning output. When a user requests the name of an entry, the server will retrieve the source of that entry's page (if one exists), transform it into HTML, and send the result.
Answer option A is incorrect. DHCP is a Dynamic Host Configuration Protocol that allocates unique (IP) addresses dynamically so that they can be used when no longer needed. A DHCP server is set up in a DHCP environment with the appropriate configuration parameters for the given network. The key parameters include the range or "pool" of available IP addresses, correct subnet masks, gateway, and name server addresses.
Answer option B is incorrect. The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched inter-network using the Internet Protocol Suite, also referred to as TCP/IP.IP is the primary protocol in the Internet Layer of the Internet Protocol Suite and has the task of delivering distinguished protocol datagrams (packets) from the source host to the destination host solely based on their addresses. For this purpose, the Internet Protocol defines addressing methods and structures for datagram encapsulation. The first major version of addressing structure, now referred to as Internet Protocol Version 4 (IPv4), is still the dominant protocol of the Internet, although the successor, Internet Protocol Version 6 (IPv6), is being deployed actively worldwide.
Answer option D is incorrect. Transmission Control Protocol (TCP) is a reliable, connection-oriented protocol operating at the transport layer of the OSI model. It provides a reliable packet delivery service encapsulated within the Internet Protocol (IP). TCP guarantees the delivery of packets, ensures proper sequencing of data, and provides a checksum feature that validates both the packet header and its data for accuracy. If the network corrupts or loses a TCP packet during transmission, TCP is responsible for retransmitting the faulty packet. It can transmit large amounts of data. Application layer protocols, such as HTTP and FTP, utilize the services of TCP to transfer files between clients and servers.
