QUESTION 27
Which of the following is a standard-based protocol that provides the highest level of VPN security?

IPSec

PPP

L2TP

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 D 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.

QUESTION 28
Which of the following is a network layer protocol used to obtain an IP address for a given hardware (MAC)
address?

PIM

RARP

ARP

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.

QUESTION 29
Which of the following is NOT an AWS Shared Responsibility Model devised by AWS?

Shared Responsibility Model for Container Services

Shared Responsibility Model for Infrastructure Services

Shared Responsibility Model for Abstract Services

Shared Responsibility Model for Storage Services

QUESTION 30
Network security is the specialist area, which consists of the provisions and policies adopted by the Network Administrator to prevent and monitor unauthorized access, misuse, modification, or denial of the computer network and network-accessible resources. For which of the following reasons is network security needed?
Each correct answer represents a complete solution. Choose all that apply.

To protect information from loss and deliver it to its destination properly

To protect information from unwanted editing, accidentally or intentionally by unauthorized users

To protect private information on the Internet

To prevent a user from sending a message to another user with the name of a third person

QUESTION 31
Which of the following is an intrusion detection system that reads all incoming packets and tries to find suspicious patterns known as signatures or rules?

HIDS

IPS

DMZ

NIDS

A network intrusion detection system (NIDS) is an intrusion detection system that tries to detect malicious activity such as denial of service attacks, port scans or even attempts to crack into computers by monitoring network traffic. A NIDS reads all the incoming packets and tries to find suspicious patterns known as signatures or rules. It also tries to detect incoming shell codes in the same manner that an ordinary intrusion detection system does.
Answer option A is incorrect. A host-based intrusion detection system (HIDS) produces a false alarm because of the abnormal behavior of users and the network. A host-based intrusion detection system (HIDS) is an intrusion detection system that monitors and analyses the internals of a computing system rather than the network packets on its external interfaces. A host-based Intrusion Detection System (HIDS) monitors all or parts of the dynamic behavior and the state of a computer system. HIDS looks at the state of a system, its stored information, whether in RAM, in the file system, log files or elsewhere; and checks that the contents of these appear as expected. Answer option B is incorrect. An intrusion prevention system (IPS) is a network security device that monitors network and/or system activities for malicious or unwanted behavior and can react, in real-time, to block or prevent those activities. When an attack is detected, it can drop the offending packets while still allowing all other traffic to pass.
Answer option C is incorrect. 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.
