10.Mark the ST connector in the image given below.

210-250

USB: A Universal Serial Bus (USB) connector is used with the USB cable for connecting various electronic
devices to a computer. USB supports a data speed of up to 12 megabits per second. Two types of
connectors are used with USB, namely USB-A Type and USB-B Type.
11.In which of the following DoS attacks does an attacker send an ICMP packet larger than 65,536 bytes
to the target system?
A. Ping of death
B. Fraggle
C. Jolt
D. Teardrop
Answer: A
210-250 exam Explanation:
In the ping of death attack, the attacker sends an ICMP packet larger than 65,536 bytes. Since the
operating system does not know how to handle a packet larger than 65,536 bytes, it either freezes or
crashes at the time of reassembling the packet. Now-a-days, operating systems discard such packets, so
the ping of death attack is not applicable at the present time.
Answer option C is incorrect. In the jolt DoS attack, an attacker fragments the ICMP packet in such a
manner that the target computer cannot reassemble it. In this situation, the CPU utilization of the target
system becomes 100 percent and the target system gets crashed.
Answer option D is incorrect. In a teardrop attack, a series of data packets are sent to the target system
with overlapping offset field values. As a result, the target system is unable to reassemble these packets
and is forced to crash, hang, or reboot.
Answer option B is incorrect. In a fraggle DoS attack, an attacker sends a large amount of UDP echo
request traffic to the IP broadcast addresses. These UDP requests have a spoofed source address of the
intended victim. If the routing device delivering traffic to those broadcast addresses delivers the IP
broadcast to all the hosts, most of the IP addresses send an ECHO reply message. However, on a
multi-access broadcast network, hundreds of computers might reply to each packet when the target
network is overwhelmed by all the messages sent simultaneously. Due to this, the network becomes
unable to provide services to all the messages and crashes.

12.Which of the following provides security for network traffic (transmitted packets) at the Network or
Internet layer?
A. IP
B. UDP
C. TCP D.
IPSec
Answer: D
210-250 pdf Explanation:
Internet Protocol Security (IPSec) is a method of securing data. It secures traffic by using encryption and
digital signing. It enhances the security of data as if an IPSec packet is captured. Its contents cannot be
read. IPSec also provides sender verification that ensures the certainty of the datagram’s origin to the
receiver.
Answer option A 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 B is incorrect. User Datagram Protocol (UDP) is one of the core members of the Internet
Protocol Suite, the set of network protocols used for the Internet. With UDP, computer applications can
send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network
without requiring prior communications to set up special transmission channels or data paths. UDP is
sometimes called the Universal Datagram Protocol.
Answer option C 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.

13.You work as a Network Security Administrator for NetPerfect Inc. The company has a Windows-based
network. You are incharge of the data and network security of the company. While performing a threat log
analysis, you observe that one of the database administrators is pilfering confidential data.
What type of threat is this?
A. Malware
B. External threat
C. Internal threat
D. Zombie
Answer: C
Explanation:
This type of threat is known as internal threat.
The difference between internal and external threats is as follows:
Internal Threat: Internal threats originate from within an organization. These threats come from the
employees and others having legal access. For example, a database administrator who has full access
rights can easily steal the data.
External Threat: External threats originate from outside an organization. These are the threats intended to
flood a network with large volumes of access requests. These threats can be countered by implementing
security controls on the perimeters of the network, such as firewalls, which limit user access to the
Internet.
Answer option B is incorrect. External threats originate from outside of an organization, not from within
the organization.
Answer option D is incorrect. A zombie is malicious software that secretly takes over another computer
connected to the Internet. The zombie’s creator uses the same computer to launch attacks that are difficult
to detect. Zombies are used in denial-of-service attacks. The attacker plants a zombie in hundreds of
computers belonging to unsuspecting third parties, and then uses these computers against targeted
websites. These computers are also called zombie computers. Zombies are also used to commit click
fraud against sites displaying pay per click advertising. Others can host phishing or money mule recruiting
websites.
Answer option A is incorrect. Malware is a combination of the terms malicious and software. It refers to a
variety of hostile programs, such as a virus or a Trojan horse, designed to damage or disrupt a computer.
It gathers information about a computer without the user’s permission or knowledge.

14.Which of the following Web sites is used by the users to browse various products and to make
purchases?
A. Micro-site
B. Internet forum
C. Social networking site
D. E-commerce site
Answer: D
210-250 vce Explanation:
Electronic commerce, commonly known as e-commerce or eCommerce, or e-business consists of the
buying and selling of products or services over electronic systems such as the Internet and other
computer networks. The amount of trade conducted electronically has grown extraordinarily with
widespread Internet usage. E-commerce sites can be used by users to browse various products and to
make purchases. Amazon.com is an example of an e-commerce site.
Answer option A is incorrect. A micro-site, also known as a mini site or weblet, is an Internet web design
term referring to an individual web page or cluster of pages which are meant to function as an auxiliary
supplement to a primary website. The micro-site’s main landing page most likely has its own domain name
or sub-domain. They are typically used to add a specialized group of information either editorial or
commercial. Such sites may be linked in to a main site or not or taken completely off a site’s server when
the site is used for a temporary purpose. The main distinction of a micro-site versus its parent site is its
purpose and specific cohesiveness as compared to the micro-site’s broader overall parent website.
Micro-sites used for editorial purposes may be a page or group of pages that, for example, may contain
information about a holiday, an event or similar item which gives more detailed information than a site’s
general content area may provide. A community organization may have its main site with all of the
organization’s basic information, but creates a separate, temporary micro-site to inform about a particular
activity, event, or similar.
Answer option B is incorrect. An Internet forum, or message board, is an online discussion site. It
originated as the modern equivalent of a traditional bulletin board, and a technological evolution of the
dialup bulletin board system. From a technological standpoint, forums or boards are web applications
managing user-generated content. People participating in an Internet forum may cultivate social bonds
and interest groups for a topic made from the discussions.
Answer option C is incorrect. Social networking Web sites provide a virtual community in which people
with a shared interest may communicate. These sites provide users the ability to create their profile page.
The users can post their thoughts, ideas, and anything else and can share it with their friends. Some
15.Cola Co. manufactures, markets, sells, and distributes non-alcoholic potables such as Lemcaa and
Thunder Up under its brand name Cola and uses green and red logo. Mola Co., a new company, starts
manufacturing, marketing, selling, and distributing non-alcoholic potables like Lumca and Cloud Up under
its brand name Mola and uses green and red logo.
Which of the following violations has been committed by Mola Co.?
A. Copyright infringement
B. Trademark infringement
C. Patent law
D. Plagiarism
Answer: B
210-250 dumps Explanation:
Trademark infringement is a violation of the exclusive rights attaching to a trademark without the
authorization of the trademark owner or any licensees (provided that such authorization was within the
scope of the license). Infringement may occur when one party, the ‘infringer’, uses a trademark that is
identical or confusingly similar to a trademark owned by another party, in relation to products or services
that are identical or similar to the products or services that the registration covers. An owner of a
trademark may commence legal proceedings against a party that infringes its registration.
Answer option C is incorrect. Patent laws are used to protect the duplication of software. Software
patents cover the algorithms and techniques that are used in creating the software. It does not cover the
entire program of the software. Patents give the author the right to make and sell his product. The time of
the patent of a product is limited though, i.e., the author of the product has the right to use the patent for
only a specific length of time.
Answer option A is incorrect. Copyright infringement, also known as copyright violation, is the use of
material which is covered by copyright law, in a way that violates one of the original copyright owner’s
exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative
works that build upon it. The slang term bootleg (from the use of boots to smuggle items) is often used to describe illegally copied material. For media such as movies and music, unauthorized copying and
distribution is occasionally called piracy or theft.
Answer option D is incorrect. Plagiarism is defined as the “use or close imitation of the language and
thoughts of another author and the representation of them as one’s own original work.” While plagiarism in
scholarship and journalism has a centuries-old history, the development of the Internet, where articles
appear as electronic text, has made the physical act of copying the work of others much easier. Plagiarism
is not copyright infringement. While both terms may apply to a particular act, they are different
transgressions. Copyright infringement is a violation of the rights of a copyright holder, when material
protected by copyright is used without consent. On the other hand, plagiarism is concerned with the
unearned increment to the plagiarizing author’s reputation that is achieved through false claims of
authorship.

17.In which of the following network topologies does the data travel around a loop in a single direction and
pass through each device?
A. Star topology B.
Ring topology C.
Mesh topology D.
Tree topology
Answer: B
Explanation:
Ring topology is a type of physical network design where all computers in the network are connected in a
closed loop. Each computer or device in a Ring topology network acts as a repeater. It transmits data by
passing a token around the network in order to prevent the collision of data between two computers that
want to send messages at the same time. If a token is free, the computer waiting to send data takes it,
attaches the data and destination address to the token, and sends it. When the token reaches its
destination computer, the data is copied. Then, the token gets back to the originator. The originator finds
that the message has been copied and received and removes the message from the token. Now, the
token is free and can be used by the other computers in the network to send data. In this topology, if one
computer fails, the entire network goes down.
Ring Topology:
210-250

Answer option A is incorrect. Star topology is a type of physical network design where each computer in
the network is connected to a central device, called hub, through an unshielded twisted-pair (UTP) wire.
Signals from the sending computer go to the hub and are then transmitted to all the computers in the
network. Since each workstation has a separate connection to the hub, it is easy to troubleshoot.
Currently, it is the most popular topology used for networks.
Star Topology:
210-250

Answer option C is incorrect. Mesh network topology is a type of physical network design where all
devices in a network are connected to each other with many redundant connections. It provides multiple
paths for the data traveling on the network to reach its destination. Mesh topology also provides
redundancy in the network. It employs the full mesh and partial mesh methods to connect devices. In a full
mesh topology network, each computer is connected to all the other computers. In a partial mesh topology
network, some of the computers are connected to all the computers, whereas some are connected to only
those computers with which they frequently exchange data.
Mesh Topology:
Answer option D is incorrect. In telecommunication networks, a tree network topology is a combination of
two or more star networks connected together. Each star network is a local area network (LAN) in which
there is a central computer or server to which all the workstation nodes are directly linked. The central
computers of the star networks are connected to a main cable called the bus. Thus, a tree network is a
bus network of star networks. The tree network topology is ideal when the workstations are located in
groups, with each group occupying a relatively small physical region. An example is a university campus in
which each building has its own star network, and all the central computers are linked in a campus-wide
system. It is easy to add or remove workstations from each star network. Entire star networks can be
added to, or removed from, the bus. If the bus has low loss and/or is equipped with repeaters, this
topology can be used in a wide area network (WAN) configuration. The tree topology is shown in the figure

18.Which of the following search engines can be operated by only using a mouse?
A. Meta-search engine
B. Mono-search engine
C. Web search engine
D. Selection-based search engine
Answer: D
Explanation:
A selection-based search engine is a search engine system in which the user invokes a search query
using only the mouse. A selection-based search system allows the user to search the internet for more
information about any keyword or phrase contained within a document or webpage in any software
application on his desktop computer using the mouse. In a selection-based search engine, the search
engine is available outside of the Web browser and highlighting a word or phrase in any document pops
up the search tool.
Answer option C is incorrect. A web search engine is designed to search for information on the World
Wide Web. The search results are usually presented in a list of results and are commonly called hits. The
information may consist of web pages, images, information and other types of files. Some search engines
also mine data available in databases or open directories. Unlike Web directories, which are maintained by
human editors, search engines operate algorithmically or are a mixture of algorithmic and human input.
Answer option A is incorrect. A meta-search engine is also known as a metacrawler. It is a search tool
that sends user requests to several other search engines and/or databases and aggregates the results
into a single list or displays them according to their source. Meta-search engines enable users to enter
search criteria once and access several search engines simultaneously. Meta-search engines operate on
the premise that the Web is too large for any one search engine to index it all and that more
comprehensive search results can be obtained by combining the results from several search engines. This
also may save the user from having to use multiple search engines separately.
Examples: Dogpile and Vivisimo.
Answer option B is incorrect. There is no such type of search engine.
