NEW QUESTION 22
Which of the following is an Internet application protocol used for transporting Usenet news articles between news servers and for reading and posting articles by end-user client applications?
- A. DCAP
- B. BOOTP
- C. NNTP
- D. NTP
Answer: C
Explanation:
The Network News Transfer Protocol (NNTP) is an Internet application protocol used for transporting Usenet news articles (netnews) between news servers and for reading and posting articles by end user client applications. NNTP is designed so that news articles are stored in a central database, allowing the subscriber to select only those items that he wants to read.
Answer option D is incorrect. Network Time Protocol (NTP) is used to synchronize the timekeeping among the number of distributed time servers and clients. It is used for the time management in a large and diverse network that contains many interfaces. In this protocol, servers define the time, and clients have to be synchronized with the defined time. These clients can choose the most reliable source of time defined from the several NTP servers for their information transmission. Answer option C is incorrect. The Data Link Switching Client Access Protocol (DCAP) is an application layer protocol that is used between workstations and routers for transporting SNA/NetBIOS traffic over TCP sessions. It was introduced in order to address a few deficiencies by the Data Link Switching Protocol (DLSw). The DLSw raises the important issues of scalability and efficiency, and since DLSw is a switch-to-switch protocol, it is not efficient when implemented on workstations. DCAP was introduced in order to address these issues.
Answer option B is incorrect. The BOOTP protocol is used by diskless workstations to collect configuration information from a network server. It is also used to acquire a boot image from the server.
NEW QUESTION 23
FILL BLANK
Fill in the blank with the appropriate term. ______________ encryption is a type of encryption that uses two
keys, i.e., a public key and a private key pair for data encryption. It is also known as public key encryption.
Answer:
Explanation:
Asymmetric
Explanation:
Asymmetric encryption is a type of encryption that uses two keys, i.e., a public key and a private key pair for
data encryption. The public key is available to everyone, while the private or secret key is available only to the
recipient of the message. For example, when a user sends a message or data to another user, the sender
uses the public key to encrypt the data. The receiver uses his private key to decrypt the data.

NEW QUESTION 26
Which of the following network scanning tools is a TCP/UDP port scanner that works as a ping sweeper and hostname resolver?
- A. Netstat
- B. Hping
- C. SuperScan
- D. Nmap
Answer: C
Explanation:
SuperScan is a TCP/UDP port scanner. It also works as a ping sweeper and hostname resolver. It can ping a given range of IP addresses and resolve the host name of the remote system.
The features of SuperScan are as follows:
It scans any port range from a built-in list or any given range.
It performs ping scans and port scans using any IP range.
It modifies the port list and port descriptions using the built in editor.
It connects to any discovered open port using user-specified "helper" applications.
It has the transmission speed control utility.
Answer option D is incorrect. Nmap is a free open-source utility for network exploration and security auditing. It is used to discover computers and services on a computer network, thus creating a "map" of the network. Just like many simple port scanners, Nmap is capable of discovering passive services. In addition, Nmap may be able to determine various details about the remote computers. These include operating system, device type, uptime, software product used to run a service, exact version number of that product, presence of some firewall techniques and, on a local area network, even vendor of the remote network card. Nmap runs on Linux, Microsoft Windows, etc.
Answer option C is incorrect. Netstat (network statistics) is a command-line tool that displays network connections (both incoming and outgoing), routing tables, and a number of network interface statistics. It is available on Unix, Unix-like, and Windows NT-based operating systems. It is used to find problems on the network and to determine the amount of traffic on the network as a performance measurement.
Answer option A is incorrect. Hping is a free packet generator and analyzer for the TCP/IP protocol. Hping is one of the de facto tools for security auditing and testing of firewalls and networks. The new version of hping, hping3, is scriptable using the Tcl language and implements an engine for string based, human readable description of TCP/IP packets, so that the programmer can write scripts related to low level TCP/IP packet manipulation and analysis in very short time. Like most tools used in computer security, hping is useful to both system administrators and crackers (or script kiddies).
NEW QUESTION 27

NEW QUESTION 28
In which of the following attacks do computers act as zombies and work together to send out bogus messages, thereby increasing the amount of phony traffic?
- A. Smurf attack
- B. DDoS attack
- C. Bonk attack
- D. Buffer-overflow attack
Answer: B
Explanation:
In the distributed denial of service (DDOS) attack, an attacker uses multiple computers throughout the network that it has previously infected. Such computers act as zombies and work together to send out bogus messages, thereby increasing the amount of phony traffic. The major advantages to an attacker of using a distributed denial-of-service attack are that multiple machines can generate more attack traffic than one machine, multiple attack machines are harder to turn off than one attack machine, and that the behavior of each attack machine can be stealthier, making it harder to track down and shut down. TFN, TRIN00, etc. are tools used for the DDoS attack.
Answer option A is incorrect. A Smurf attack is a type of attack that uses third-party intermediaries to defend against, and get back to the originating system. In a Smurf attack, a false ping packet is forwarded by the originating system. The broadcast address of the third-party network is the packet's destination. Hence, each machine on the third-party network has a copy of the ping request. The victim system is the originator. The originator rapidly forwards a large number of these requests via different intermediary networks. The victim gets overwhelmed by these large number of requests.
Answer option B is incorrect. A buffer-overflow attack is performed when a hacker fills a field, typically an address bar, with more characters than it can accommodate. The excess characters can be run as executable code, effectively giving the hacker control of the computer and overriding any security measures set. There are two main types of buffer overflow attacks:
stack-based buffer overflow attack:
Stack-based buffer overflow attack uses a memory object known as a stack. The hacker develops the code which reserves a specific amount of space for the stack. If the input of user is longer than the amount of space reserved for it within the stack, then the stack will overflow.
heap-based buffer overflow attack:
Heap-based overflow attack floods the memory space reserved for the programs.
Answer option D is incorrect. Bonk attack is a variant of the teardrop attack that affects mostly Windows computers by sending corrupt UDP packets to DNS port 53. It is a type of denial-of-service (DoS) attack. A bonk attack manipulates a fragment offset field in TCP/IP packets. This field tells a computer how to reconstruct a packet that was fragmented, because it is difficult to transmit big packets. A bonk attack causes the target computer to reassemble a packet that is too big to be reassembled and causes the target computer to crash.

DRAG DROP
George works as a Network Administrator for Blue Soft Inc. The company uses Windows Vista operating system. The network of the company is continuously connected to the Internet. What will George use to protect the network of the company from intrusion?
ECCouncil 312-38 Exam
Answer:
Explanation:
Explanation:
A firewall is a set of related programs configured to protect private networks connected to the Internet from intrusion. It is used to regulate the network traffic between different computer networks. It permits or denies the transmission of a network packet to its destination based on a set of rules. A firewall is often installed on a separate computer so that an incoming packet does not get into the network directly.
NEW QUESTION 34
CORRECT TEXT
Fill in the blanks with the appropriate terms. In L2TP ______________ tunnel mode, the ISP must support L2TP, whereas in L2TP tunnel mode, the ISP does not need to support L2TP.
Answer:
Explanation:
compulsory
Explanation:
The Layer 2 Tunnel Protocol is one of the tunneling protocols that is used in a virtual private network. It contains the functionality of Cisco's Layer 2 Forwarding (L2F) protocol and Microsoft's Point-to-Point Tunneling Protocol (PPTP). This protocol is vendor interoperable and supports multihopping.L2TP supports two tunnel modes: Compulsory tunnel: In L2TP compulsory tunnel mode, a remote host initiates a connection to its Internet Service Provider (ISP). An L2TP connection is established between the remote user and the corporate network by the ISP. With a compulsory tunnel, the ISP must support L2TP. Voluntary tunnel: In L2TP voluntary tunnel mode, the connection is created by the remote user, typically by using an L2TP tunneling client. Then, the remote user sends L2TP packets to its ISP in order to forward them on to the corporate network. With a voluntary tunnel, the ISP does not need to support L2TP.

NEW QUESTION 36
Adam, a malicious hacker, has just succeeded in stealing a secure cookie via a XSS attack. He is able to
replay the cookie even while the session is valid on the server. Which of the following is the most likely reason
of this cause?
- A. Encryption is performed at the network layer (layer 1 encryption).
- B. Encryption is performed at the application layer (single encryption key).
- C. Two way encryption is applied.
- D. No encryption is applied.
Answer: B
Explanation:
Single key encryption uses a single word or phrase as the key. The same key is used by the sender to encrypt
and the receiver to decrypt. Sender and receiver initially need to have a secure way of passing the key from
one to the other. With TLS or SSL this would not be possible. Symmetric encryption is a type of encryption that
uses a single key to encrypt and decrypt data. Symmetric encryption algorithms are faster than public key
encryption. Therefore, it is commonly used when a message sender needs to encrypt a large amount of data.
Data Encryption Standard (DES) uses the symmetric encryption key algorithm to encrypt data.
