    • бескласни протокол за рутирање

    • класни протокол за рутирање

    Correct Answer
    A. бескласни протокол за рутирање
    Explanation
    When using VLSM (Variable Length Subnet Mask) and CIDR (Classless Inter-Domain Routing), it is necessary to use a classless routing protocol. This is because VLSM and CIDR allow for the allocation of subnet masks of varying lengths, which means that the traditional classful routing protocols that rely on fixed-length subnet masks (such as classful routing protocols) are not suitable for this scenario. Therefore, a classless routing protocol is required to properly handle the variable length subnet masks used in VLSM and CIDR.

    • Omogucava aplikacionom procesu da pristupi OSI okruzenju

    • Obezbedjuje fizicki prenos podataka

    • Obezbedjuje konverziju podataka

    • Omogucava korisniku da pristupi internetu

    Correct Answer
    A. Omogucava aplikacionom procesu da pristupi OSI okruzenju
    Explanation
    The correct answer is "omogucava aplikacionom procesu da pristupi OSI okruzenju." This function of the application layer allows the application process to access the OSI environment. The application layer is responsible for providing services and protocols that enable communication between applications on different devices. It allows applications to establish, manage, and terminate connections with other applications over a network. This layer also handles tasks such as data encryption, compression, and formatting for transmission.

    Skup slojeva I protokola naziva se:

    • Interfejsna arhitektura

    • Slojevita arhitektura

    • Kodirana arhitektura

    • Mrezna arhitektura

    Correct Answer
    A. Slojevita arhitektura
    Explanation
    The correct answer is "Slojevita arhitektura" (Layered architecture). This term refers to the organization of network protocols and layers into a hierarchical structure. In a layered architecture, each layer has a specific function and interacts with adjacent layers to provide a complete network communication. This approach allows for modular design, easy troubleshooting, and the ability to replace or upgrade individual layers without affecting the entire system.

    Promena jednog sloja u OSI modelu:

    • Nema uticaja na ostale slojeve sto omogucava da se promena mrezne konfiguracije izvrsi bez promene na ostalim slojevima

    • Ima uticaja na ostale slojeve sto omogucava da se promena mrezne konfiguracije izvrsi bez promene na ostalim slojevima

    • Ima uticaja samo na vise slojeve, sto ne omogucava da se primeni mrezne konfiguraacije izvrse bez promena na ostalim slojevima

    • Ima uticaja samo na nize slojeve, sto ne omogucava da se primeni mrezne konfiguraacije izvrse bez promena na ostalim slojevima

    Correct Answer
    A. Nema uticaja na ostale slojeve sto omogucava da se promena mrezne konfiguracije izvrsi bez promene na ostalim slojevima
    Explanation
    The correct answer states that a change in one layer of the OSI model does not affect the other layers, allowing for a change in network configuration without affecting the other layers. This means that modifications can be made to the network without disrupting the functionality of the other layers.

    Fizicki sloj OSI modela:

    • Bavi se prenosom bitova izmedju dva uredjaja

    • Zaduzen je za kontrolu i detekciju gresaka

    • Bavi se logickim adresiranjem I rutiranjem podataka po mrezi

    • Odredjuje koji je tip veze potreban upostaviti I po potrebi vrsi segmentaciju podataka u datagrame

    Correct Answer
    A. Bavi se prenosom bitova izmedju dva uredjaja
    Explanation
    The physical layer of the OSI model is responsible for the transmission of bits between two devices. It deals with the actual physical connection and the electrical, mechanical, and functional specifications for the physical medium used for communication. This layer ensures that the bits are transmitted accurately and reliably from one device to another.

    Pranjak celine (peer) su:

    • Isti slojevi na razlicitim masinama

    • Susedni slojevi na istim masinama

    • Bilo koja dva sloja na jednoj masini

    • Prva dva sloja na drugoj masini

    Correct Answer
    A. Isti slojevi na razlicitim masinama
    Explanation
    The correct answer is "isti slojevi na razlicitim masinama" which means "same layers on different machines" in English. This suggests that Pranjak and Celine are referring to the layers of something (possibly software or network architecture) that are the same on different machines. This implies that they are discussing the consistency of layers across multiple machines, rather than the proximity or combination of layers on the same machine.

    Koji referentni model je standardizovan od ISO?

    • X.25

    • TCP/IP

    • OSI

    • ATM

    Correct Answer
    A. OSI
    Explanation
    The correct answer is OSI. The ISO (International Organization for Standardization) has standardized the OSI (Open Systems Interconnection) reference model. This model is a conceptual framework that standardizes the functions of a communication system into seven layers, allowing different systems to communicate with each other. X.25, TCP/IP, and ATM are all networking protocols or technologies, but they are not the referent model standardized by ISO.
