  B. Repeater
  C. PCI card
  D. Modem
  D. Modem

• Question 522:

  Which of the following is a process of transformation where the old system can no longer be maintained?

  A. Disaster
  B. Risk
  C. Threat
  D. Crisis
  D. Crisis

• Question 523:

  Which of the following layers of the TCP/IP model maintains data integrity by ensuring that messages are delivered in the order in which they are sent and that there is no loss or duplication?

  A. Transport layer
  B. Link layer
  C. Internet layer
  D. Application layer
  A. Transport layer

  ---

  Explanation/Reference:

  The transport layer ensures that messages are delivered in the order in which they are sent and that there is no loss or duplication. Transport layer maintains data integrity. Answer option C is incorrect. The Internet Layer of the TCP/IP model solves the problem of sending packets across one or more networks. Internetworking requires sending data from the source network to the destination network. This process is called routing. IP can carry data for a number of different upper layer protocols. Answer option B is incorrect. The Link Layer of TCP/IP model is the networking scope of the local network connection to which a host is attached. This is the lowest component layer of the Internet protocols, as TCP/IP is designed to be hardware independent. As a result, TCP/IP has been implemented on top of virtually any hardware networking technology in existence. The Link Layer is used to move packets between the Internet Layer interfaces of two different hosts on the same link. The processes of transmitting and receiving packets on a given link can be controlled both in the software device driver for the network card, as well as on firmware or specialized chipsets. Answer option D is incorrect. The Application Layer of TCP/IP model refers to the higher-level protocols used by most applications for network communication. Examples of application layer protocols include the File Transfer Protocol (FTP) and the Simple Mail Transfer Protocol (SMTP). Data coded according to application layer protocols are then encapsulated into one or more transport layer protocols, which in turn use lower layer protocols to affect actual data transfer.

• Question 524:

  Which risk management phase helps in establishing context and quantifying risks?

  A. Risk identification
  B. Risk assessment
  C. Risk review
  D. Risk treatment
  B. Risk assessment

• Question 525:

  Which of the following routing metrics refers to the time required to transfer the package to the source via the Internet?

  A. None
  B. routing delay
  C. length of the trail
  D. charge
  E. bandwidth
  B. routing delay

• Question 526:

  Simran is a network administrator at a start-up called Revolution. To ensure that neither party in the company can deny getting email notifications or any other communication, she mandates authentication before a connection establishment or message transfer occurs. What fundamental attribute of network defense is she enforcing?

  A. Integrity
  B. Non-repudiation
  C. Confidentiality
  D. Authentication
  B. Non-repudiation

• Question 527:

  Which of the following OSI layers establishes, manages, and terminates the connections between the local and remote applications?

  A. Data Link layer
  B. Network layer
  C. Application layer
  D. Session layer
  D. Session layer

  ---

  Explanation/Reference:

  The session layer of the OSI/RM controls the dialogues (connections) between computers. It establishes, manages and terminates the connections between the local and remote application. It provides for full-duplex, half-duplex, or simplex operation, and establishes checkpointing, adjournment, termination, and restart procedures. The OSI model made this layer responsible for graceful close of sessions, which is a property of the Transmission Control Protocol, and also for session checkpointing and recovery, which is not usually used in the Internet Protocol Suite. The Session Layer is commonly implemented explicitly in application environments that use remote procedure calls. Answer option C is incorrect. The Application Layer of TCP/IP model refers to the higher-level protocols used by most applications for network communication. Examples of application layer protocols include the File Transfer Protocol (FTP) and the Simple Mail Transfer Protocol (SMTP). Data coded according to application layer protocols are then encapsulated into one or more transport layer protocols, which in turn use lower layer protocols to affect actual data transfer. Answer option A is incorrect. The Data Link Layer is Layer 2 of the seven-layer OSI model of computer networking. It corresponds to or is part of the link layer of the TCP/IP reference model. The Data Link Layer is the protocol layer which transfers data between adjacent network nodes in a wide area network or between nodes on the same local area network segment. The Data Link Layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors that may occur in the Physical Layer. Examples of data link protocols are Ethernet for local area networks (multi-node), the Point-to-Point Protocol (PPP), HDLC, and ADCCP for point-to-point (dual-node) connections. Answer option B is incorrect. The network layer controls the operation of subnet, deciding which physical path the data should take, based on network conditions, priority of service, and other factors. Routers work on the Network layer of the OSI stack.

• Question 528:

  Which of the following provides a set of voluntary recommended cyber security features to include in network-capable IoT devices?

  A. FGMA
  B. GLBA
  C. GCMA
  D. NIST
  D. NIST

• Question 529:

  Which of the following router configuration modes changes terminal settings on a temporary basis, performs basic tests, and lists system information?

  A. Global Config
  B. Interface Config
  C. Privileged EXEC
  D. User EXEC
  D. User EXEC

  ---

  Explanation/Reference:

  User EXEC is one of the router configuration modes that changes terminal settings on a temporary basis, performs basic tests, and lists system information.

  Answer option C is incorrect. Privileged EXEC sets operating parameters.

  Answer option A is incorrect. Global Config modifies configuration that affects the system as a whole.

  Answer option B is incorrect. Interface Config modifies the operation of an interface.

• Question 530:

  Which of the following is an attack on a website that changes the appearance of the site and seriously damage the website trust and reputation?

  A. None
  B. website defacement
  C. spoofing
  D. Buffer overflow
