NEW QUESTION 29
Which of the following protocols is used to share information between routers to transport IP Multicast packets
among networks?
- A. RPC
- B. LWAPP
- C. RSVP
- 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 31
Which of the following are the six different phases of the Incident handling process? Each correct answer
represents a complete solution. Choose all that apply.
- A. Containment
- B. Preparation
- C. Post mortem review
- D. Recovery
- E. Identification
- F. Eradication
- G. Lessons learned
Answer: A,B,D,E,F,G
Explanation:
Following are the six different phases of the Incident handling process:
1.Preparation: Preparation is the first step in the incident handling process. It includes processes like backing
up copies of all key data on a regular basis, monitoring and updating software on a regular basis, and creating
and implementing a documented security policy. To apply this step a documented security policy is formulated
that outlines the responses to various incidents, as a reliable set of instructions during the time of an incident.
The following list contains items that the incident handler should maintain in the preparation phase i.e. before
an incident occurs:
Establish applicable policies
Build relationships with key players
Build response kit
Create incident checklists
Establish communication plan
Perform threat modeling
Build an incident response team
Practice the demo incidents
2.Identification: The Identification phase of the Incident handling process is the stage at which the Incident
handler evaluates the critical level of an incident for an enterprise or system. It is an important stage where the
distinction between an event and an incident is determined, measured and tested.
3.Containment: The Containment phase of the Incident handling process supports and builds up the incident
combating process. It helps in ensuring the stability of the system and also confirms that the incident does not
get any worse.
4.Eradication: The Eradication phase of the Incident handling process involves the cleaning-up of the identified
harmful incidents from the system. It includes the analyzing of the information that has been gathered for
determining how the attack was committed. To prevent the incident from happening again, it is vital to
recognize how it was conceded out so that a prevention technique is applied.
5.Recovery: Recovery is the fifth step of the incident handling process. In this phase, the Incident Handler
places the system back into the working environment. In the recovery phase the Incident Handler also works
with the questions to validate that the system recovery is successful. This involves testing the system to make
sure that all the processes and functions are working normal. The Incident Handler also monitors the system to
make sure that the systems are not compromised again. It looks for additional signs of attack.
6.Lessons learned: Lessons learned is the sixth and the final step of incident handling process. The Incident
Handler utilizes the knowledge and experience he learned during the handling of the incident to enhance and
improve the incident-handling process. This is the most ignorant step of all incident handling processes. Many
times the Incident Handlers are relieved to have systems back to normal and get busy trying to catch up other
unfinished work. The Incident Handler should make documents related to the incident or look for ways to
improve the process.
Answer option C is incorrect. The post mortem review is one of the phases of the Incident response process.

NEW QUESTION 36
Which of the following is a standard-based protocol that provides the highest level of VPN security?
- A. L2TP
- B. PPP
- C. IPSec
- D. IP
Answer: C
Explanation:
Internet Protocol Security (IPSec) is a standard-based protocol that provides the highest level of VPN security. IPSec can encrypt virtually everything above the networking layer. It is used for VPN connections that use the L2TP protocol. It secures both data and password. IPSec cannot be used with Point-to-Point Tunneling Protocol (PPTP). 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 C is incorrect. Point-to-Point Protocol (PPP) is a remote access protocol commonly used to connect to the Internet. It supports compression and encryption and can be used to connect to a variety of networks. It can connect to a network running on the IPX, TCP/IP, or NetBEUI protocol. It supports multi-protocol and dynamic IP assignments. It is the default protocol for the Microsoft Dial-Up adapter. Answer option A is incorrect. Layer 2 Tunneling Protocol (L2TP) is a more secure version of Point-to-Point Tunneling Protocol (PPTP). It provides tunneling, address assignment, and authentication. It allows the transfer of Point-to-Point Protocol (PPP) traffic between different networks.L2TP combines with IPSec to provide tunneling and security for Internet Protocol (IP), Internetwork Packet Exchange (IPX), and other protocol packets across IP networks.

NEW QUESTION 38
Which of the following is a telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between end-points in a wide area network (WAN)?
- A. X.25
- B. ISDN
- C. PPP
- D. Frame relay
- E. None
Answer: D
Explanation:
Frame relay is a telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between end-points in a wide area network (WAN). Frame relay puts data in a variable-size unit called a frame. It checks for lesser errors as compared to other traditional forms of packet switching and hence speeds up data transmission. When an error is detected in a frame, it is simply dropped. The end points are responsible for detecting and retransmitting dropped frames.
Answer option C is incorrect. Integrated Services Digital Network (ISDN) is a digital telephone/ telecommunication network that carries voice, data, and video over an existing telephone network infrastructure. It requires an ISDN modem at both the ends of a transmission. ISDN is designed to provide a single interface for hooking up a telephone, fax machine, computer, etc. ISDN has two levels of service, i.e., Basic Rate Interface (BRI) and Primary Rate Interface (PRI).
Answer option A is incorrect. The Point-to-Point Protocol, or PPP, is a data link protocol commonly used to establish a direct connection between two networking nodes. It can provide connection authentication, transmission encryption privacy, and compression. PPP is commonly used as a data link layer protocol for connection over synchronous and asynchronous circuits, where it has largely superseded the older, non- standard Serial Line Internet Protocol (SLIP) and telephone company mandated standards (such as Link Access Protocol, Balanced (LAPB) in the X.25 protocol suite). PPP was designed to work with numerous network layer protocols, including Internet Protocol (IP), Novell's Internetwork Packet Exchange (IPX), NBF, and AppleTalk.
Answer option D is incorrect. The X.25 protocol, adopted as a standard by the Consultative Committee for International Telegraph and Telephone (CCITT), is a commonly-used network protocol. The X.25 protocol allows computers on different public networks (such as CompuServe, Tymnet, or a TCP/IP network) to communicate through an intermediary computer at the network layer level. X.25's protocols correspond closely to the data-link and physical-layer protocols defined in the Open Systems Interconnection (OSI) communication model.

NEW QUESTION 42
Which of the following is a network layer protocol used to obtain an IP address for a given hardware (MAC) address?
- A. PIM
- B. RARP
- C. ARP
- D. IP
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.

NEW QUESTION 45
Which of the following is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration?
- A. SLP
- B. NTP
- C. NNTP
- D. DCAP
Answer: A
Explanation:
The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks. Answer option C is incorrect. 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 A 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 D 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.
