FILL BLANK
Fill in the blank with the appropriate term. A ______________________ 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 for
preventing the collision of data between two computers that want to send messages at the same time.
Answer:
Explanation:
Token Ring
Explanation:
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.
Working:
Empty information frames are constantly circulated on the ring. When a computer has a message to send, it
adds a token to an empty frame and adds a message and a destination identifier to the frame. The frame is
then observed by each successive workstation. If the workstation sees that it is the destination for the
message, it copies the message from the frame and modifies the token back to 0. When the frame gets back
to the originator, it sees that the token has been modified to 0 and that the message has been copied and
received. It removes the message from the particular frame. The frame continues to circulate as an empty
frame, ready to be taken by a workstation when it has a message to send.
NEW QUESTION 49
Which of the following policies is used to add additional information about the overall security posture and serves to protect employees and organizations from inefficiency or ambiguity?
- A. IT policy
- B. Issue-Specific Security Policy
- C. Group policy

Explanation:
The Issue-Specific Security Policy (ISSP) is used to add additional information about the overall security posture. It helps in providing detailed, targeted guidance for instructing organizations in the secure use of tech systems. This policy serves to protect employees and organizations from inefficiency or ambiguity. Answer option A is incorrect. A user policy helps in defining what users can and should do to use network and organization's computer equipment. It also defines what limitations are put on users for maintaining the network secure such as whether users can install programs on their workstations, types of programs users are using, and how users can access data. Answer option D is incorrect. IT policy includes general policies for the IT department. These policies are intended to keep the network secure and stable. It includes the following: Virus incident and security incident Backup policy Client update policies Server configuration, patch update, and modification policies (security) Firewall policiesDmz policy, email retention, and auto forwarded email policy Answer option B is incorrect. A group policy specifies how programs, network resources, and the operating system work for users and computers in an organization.

NEW QUESTION 51
CORRECT TEXT
Fill in the blank with the appropriate term.
A ______________ is a physical or logical subnetwork that contains and exposes external services of an organization to a larger network.
Answer:
Explanation:
demilitarized zone
Explanation:
A demilitarized zone (DMZ) is a physical or logical subnetwork that contains and exposes external services of an organization to a larger network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's Local Area Network (LAN); an external attacker only has access to equipment in the DMZ, rather than the whole of the network. Hosts in the DMZ have limited connectivity to specific hosts in the internal network, though communication with other hosts in the DMZ and to the external network is allowed. This allows hosts in the DMZ to provide services to both the internal and external networks, while an intervening firewall controls the traffic between the DMZ servers and the internal network clients. In a DMZ configuration, most computers on the LAN run behind a firewall connected to a public network such as the Internet.

- C. DSL
- D. Analog modem
Answer: A,C
Explanation:
DSL and Cable modems are used in remote-access WAN technology for connecting to the Internet. Both provide an "always on" Internet access service. Answer options C and A are incorrect. Analog and Digital modems are not always in 'ON' mode when connecting to an ISP. Analog modems transmit analog voice signals, while Digital modems transmit digital signals over a link.
NEW QUESTION 56
Which of the following protocols is used to share information between routers to transport IP Multicast packets
among networks?
- A. RPC
- B. RSVP
- C. LWAPP
- D. DVMRP
Answer: D
Explanation:
The Distance Vector Multicast Routing Protocol (DVMRP) is used to share information between routers to
transport IP Multicast packets among networks. It uses a reverse path-flooding technique and is used as the
basis for the Internet's multicast backbone (MBONE). In particular, DVMRP is notorious for poor network
scaling, resulting from reflooding, particularly with versions that do not implement pruning. DVMRP's flat
unicast routing mechanism also affects its capability to scale.
Answer option A is incorrect. The Resource Reservation Protocol (RSVP) is a Transport layer protocol
designed to reserve resources across a network for an integrated services Internet. RSVP does not transport
application data but is rather an Internet control protocol, like ICMP, IGMP, or routing protocols. RSVP provides
receiver-initiated setup of resource reservations for multicast or unicast data flows with scaling and robustness.
RSVP can be used by either hosts or routers to request or deliver specific levels of quality of service (QoS) for
application data streams. RSVP defines how applications place reservations and how they can leave the
reserved resources once the need for them has ended. RSVP operation will generally result in resources being
reserved in each node along a path.
Answer option C is incorrect. A remote procedure call (RPC) hides the details of the network by using the
common procedure call mechanism familiar to every programmer. Like any ordinary procedure, RPC is also
synchronous and parameters are passed to it. A process of the client calls a function on a remote server and
remains suspended until it gets back the results.
Answer option D is incorrect. LWAPP (Lightweight Access Point Protocol) is a protocol used to control multiple
Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring, or
troubleshooting a large network. This also allows network administrators to closely analyze the network.
NEW QUESTION 57
Which of the following are the common security problems involved in communications and email? Each correct
answer represents a complete solution. Choose all that apply.
- A. Identity theft
- B. False message
- C. Eavesdropping
- D. Message replay
- E. Message repudiation
- F. Message digest
- G. Message modification
Answer: A,B,C,D,E,G
Explanation:
Following are the common security problems involved in communications and email:
Eavesdropping: It is the act of secretly listening to private information through telephone lines, e-mail, instant
messaging, and any other method of communication considered private.
Identity theft: It is the act of obtaining someone's username and password to access his/her email servers for
reading email and sending false email messages. These credentials can be obtained by eavesdropping on
SMTP, POP, IMAP, or Webmail connections.
Message modification: The person who has system administrator permission on any of the SMTP servers can
visit anyone's message and can delete or change the message before it continues on to its destination. The
recipient has no way of telling that the email message has been altered.
False message: It the act of constructing messages that appear to be sent by someone else.
Message replay: In a message replay, messages are modified, saved, and re-sent later.
Message repudiation: In message repudiation, normal email messages can be forged. There is no way for the
receiver to prove that someone had sent him/her a particular message. This means that even if someone has
sent a message, he/she can successfully deny it.
Answer option B is incorrect. A message digest is a number that is created algorithmically from a file and
represents that file uniquely.
NEW QUESTION 58
Which of the following statements best describes the consequences of the disaster recovery plan test?
- A. If no deficiencies were found during the test, then the plan is probably perfect.
- B. If no deficiencies were found during the test, then the test was probably flawed.
- C. The results of the test should be kept secret.
- D. The plan should not be changed no matter what the results of the test would be.
Answer: B
Explanation:
The chief objective of a disaster recovery plan is to provide a planned way to make decisions if a disruptive event occurs. The reason behind the disaster recovery plan test is to find flaws in the plan. Every plan has some weak points. After the test has been conducted, all parties are informed of the results and the plan is updated to reflect the new information.

NEW QUESTION 61
Which of the following refers to the exploitation of a valid computer session to gain unauthorized access to information or services in a computer system?
- A. Session hijacking
- B. Smurf
- C. Spoofing
- D. Phishing
Answer: A
Explanation:
Session hijacking refers to the exploitation of a valid computer session to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a remote server. It has particular relevance to Web developers, as the HTTP cookies used to maintain a session on many Web sites can be easily stolen by an attacker using an intermediary computer or with access to the saved cookies on the victim's computer (see HTTP cookie theft).
TCP session hijacking is when a hacker takes over a TCP session between two machines. Since most authentication only occurs at the start of a TCP session, this allows the hacker to gain access to a machine.
Answer option A is incorrect. Spoofing is a technique that makes a transmission appear to have come from an authentic source by forging the IP address, email address, caller ID, etc. In IP spoofing, a hacker modifies packet headers by using someone else's IP address to hide his identity. However, spoofing cannot be used while surfing the Internet, chatting on-line, etc. because forging the source IP address causes the responses to be misdirected.
Answer option B is incorrect. Smurf is an attack that generates significant computer network traffic on a victim network. This is a type of denial-of-service attack that floods a target system via spoofed broadcast ping messages. In such attacks, a perpetrator sends a large amount of ICMP echo request (ping) traffic to IP broadcast addresses, all of which have a spoofed source IP address of the intended victim. If the routing device delivering traffic to those broadcast addresses delivers the IP broadcast to all hosts, most hosts on that IP network will take the ICMP echo request and reply to it with an echo reply, which multiplies the traffic by the number of hosts responding.
Answer option D is incorrect. Phishing is a type of scam that entices a user to disclose personal information such as social security number, bank account details, or credit card number. An example of phishing attack is a fraudulent e-mail that appears to come from a user's bank asking to change his online banking password.
When the user clicks the link available on the e-mail, it directs him to a phishing site which replicates the original bank site. The phishing site lures the user to provide his personal information.
NEW QUESTION 62
Which of the following is a computer networking protocol used by hosts to retrieve IP address assignments and other configuration information?
- A. ARP
- B. SNMP
- C. Telnet
- D. DHCP
Answer: D
Explanation:
The Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts (DHCP clients) to retrieve IP address assignments and other configuration information. DHCP uses a client-server architecture. The client sends a broadcast request for configuration information. The DHCP server receives the request and responds with configuration information from its configuration database. In the absence of DHCP, all hosts on a network must be manually configured individually - a time-consuming and often error-prone undertaking. DHCP is popular with ISP's because it allows a host to obtain a temporary IP address. Answer option B is incorrect. Address Resolution Protocol (ARP) is a network maintenance protocol of the TCP/IP protocol suite. It is responsible for the resolution of IP addresses to media access control (MAC) addresses of a network interface card (NIC). The ARP cache is used to maintain a correlation between a MAC address and its corresponding IP address. ARP provides the protocol rules for making this correlation and providing address conversion in both directions. ARP is limited to physical network systems that support broadcast packets. Answer option A is incorrect. The Simple Network Management Protocol (SNMP) allows a monitored device (for example, a router or a switch) to run an SNMP agent. This protocol is used for managing many network devices remotely. When a monitored device runs an SNMP agent, an SNMP server can then query the SNMP agent running on the device to collect information such as utilization statistics or device configuration information. An SNMP-managed network typically consists of three components: managed devices, agents, and one or more network management systems. Answer option D is incorrect. Telnet (Telecommunication network) is a network protocol used on the Internet or local area networks to provide a bidirectional interactive communications facility. Typically, Telnet provides access to a command-line interface on a remote host via a virtual terminal connection which consists of an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). User data is interspersed in-band with TELNET control information. Typically, the Telnet protocol is used to establish a connection to Transmission Control Protocol (TCP) port number 23.

NEW QUESTION 65
Which of the following is a network layer protocol used to obtain an IP address for a given hardware (MAC)
address?
- A. ARP
- B. RARP
- C. IP
- D. PIM
Answer: B
Explanation:
Reverse Address Resolution Protocol (RARP) is a Network layer protocol used to obtain an IP address for a
given hardware (MAC) address. RARP is sort of the reverse of an ARP. Common protocols that use RARP are
BOOTP and DHCP.
Answer option D is incorrect. Address Resolution Protocol (ARP) is a network maintenance protocol of the
TCP/IP protocol suite. It is responsible for the resolution of IP addresses to media access control (MAC)
addresses of a network interface card (NIC). The ARP cache is used to maintain a correlation between a MAC
address and its corresponding IP address. ARP provides the protocol rules for making this correlation and
providing address conversion in both directions. ARP is limited to physical network systems that support
broadcast packets.
Answer option B is incorrect. Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for
Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN,
WAN, or the Internet. It is termed protocol-independent because PIM does not include its own topology
discovery mechanism, but instead uses routing information supplied by other traditional routing protocols, such
as Border Gateway Protocol (BGP).
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.
