    Transport Layer
    Explanation
    The Transport Layer provides communication services directly to the application processes that are running on different network hosts. This layer is responsible for establishing a reliable and efficient communication channel between the sender and receiver. It ensures that data is delivered in the correct order, without errors, and with the appropriate flow control. The Transport Layer also handles segmentation and reassembly of data packets, as well as error detection and correction. Overall, it manages end-to-end communication and guarantees the reliable delivery of data between applications.

      Network Layer

    • B.

      Transport Layer

    • C.

      Application Layer

    • D.

      Data-Link Layer

    Correct Answer
    D. Data-Link Layer
    Explanation
    The Data-Link Layer is the correct answer because it is responsible for the physical transmission of data over the network. This layer deals with the protocols and technologies used to transmit data between devices on the same network. It includes functions such as framing, error detection, and media access control. The diversity in this layer comes from the wide range of technologies and protocols that can be used, such as Ethernet, Wi-Fi, and Bluetooth, each with its own set of specifications and standards.

    • E.

      128

    Correct Answer
    B. 32
    Explanation
    An IPv4 address is a 32-bit address, which means it is composed of 32 binary digits (bits). Each bit can have a value of either 0 or 1, resulting in a total of 2^32 possible unique addresses. This address format is commonly used in computer networks to identify and locate devices connected to the internet.

    In a class B address, which of the octets are the host portion and are assigned locally?

    • A.

      The first octet is assigned locally

    • B.

      The first and second octets are assigned locally

    • C.

      The second and third octets are assigned locally

    • D.

      The third and forth octets are assigned locally

    Correct Answer
    D. The third and forth octets are assigned locally
    Explanation
    In a class B address, the third and fourth octets are assigned locally. This means that the network administrator can assign any value to these octets within the range of 0 to 255 to create unique IP addresses within the network. The first and second octets, on the other hand, are used to identify the network itself and cannot be changed.

    Which of the following statements is true of a directed-broadcast address?

    • A.

      A broadcast address is an address that has all 0's in the host field

    • B.

      Any IP address in a network can be used as a broadcast address

    • C.

      A directed-broadcast address is an address that has all 1's in the host field

    • D.

      None of the above is correct

    Correct Answer
    C. A directed-broadcast address is an address that has all 1's in the host field
    Explanation
    A directed-broadcast address is an address that has all 1's in the host field. This means that in a network, when a packet is sent to a directed-broadcast address, it will be delivered to all hosts within that network. This is different from a regular broadcast address, which has all 0's in the host field and is used to send a packet to all hosts on the entire network. Therefore, the correct statement is that a directed-broadcast address has all 1's in the host field.

    Whick two of these addresses are privat IP addresses?

    • A.

      10.215.34.124

    • B.

      127.16.71.43

    • C.

      172.17.10.10

    • D.

      255.200.15.10

    Correct Answer(s)
    A. 10.215.34.124
    C. 172.17.10.10
    Explanation
    The two private IP addresses are 10.215.34.124 and 172.17.10.10. Private IP addresses are reserved for use within private networks and are not routable on the internet. The address range 10.0.0.0 to 10.255.255.255 (10.0.0.0/8) is reserved for private networks. Similarly, the address range 172.16.0.0 to 172.31.255.255 (172.16.0.0/12) is also reserved for private networks. Therefore, both 10.215.34.124 and 172.17.10.10 fall within these private address ranges.

    Which three statements about IP are accurate?

    • A.

      IP is a connectionless protocol

    • B.

      IP uses relational addressing

    • C.

      IP delivers data reliability

    • D.

      IP operates at Layer 2 of the TCP/IP stack and OSI model

    • E.

      IP does not provide any recovery functions

    • F.

      IP delivers data on a best effort basis

    Correct Answer(s)
    A. IP is a connectionless protocol
    E. IP does not provide any recovery functions
    F. IP delivers data on a best effort basis
    Explanation
    IP is a connectionless protocol, meaning that it does not establish a dedicated connection before transmitting data. It uses relational addressing to identify devices on a network. However, IP does not provide any recovery functions, so it does not guarantee the delivery of data. Instead, it delivers data on a best effort basis, meaning that it tries its best to deliver data but does not ensure reliability. IP operates at Layer 3 of the TCP/IP stack and OSI model, not Layer 2.
