    • Treći sloj

    Correct Answer
    A. Treći sloj
    Explanation
    The correct answer is "Treći sloj" which translates to "Third layer" in English. This suggests that the question is asking about the layer of the network in the OSI model. The OSI model is a conceptual framework used to understand how different network protocols and technologies interact. It consists of seven layers, with the third layer being the Network layer. This layer is responsible for addressing, routing, and delivering data packets across different networks. Therefore, the correct answer is "Treći sloj" or "Third layer" in English.

    Jedinica podataka drugog sloja OSI referentnog modela je:

    • Ram

    • Paket

    • Bit

    • Segment

    Correct Answer
    A. Ram
    Explanation
    The correct answer is Ram. In the OSI reference model, the second layer is the Data Link Layer, which is responsible for the reliable transmission of data between two nodes on a network. The unit of data at this layer is called a frame, and it is stored in the computer's memory known as Random Access Memory (RAM) before being transmitted over the network. RAM is a volatile memory that allows for fast read and write operations, making it suitable for temporarily storing data before it is sent across the network.

    Prva tri okteta MAC adrese označavaju:

    • Klasu kojoj pripada adresa

    • ID mrežne kartice

    • Tip kartice (Eternet, bežična...)

    • Proizvođača

    Correct Answer
    A. Proizvođača
    Explanation
    The first three octets of a MAC address indicate the manufacturer or vendor of the network interface card. This is known as the OUI (Organizationally Unique Identifier) and is assigned by the Institute of Electrical and Electronics Engineers (IEEE). Each manufacturer is assigned a unique OUI, allowing them to be identified based on the MAC address of their devices.

    Kod PAP protokola lozinka se šalje kao:

    • Šifrovan tekst

    • Čitljiv tekst

    • Uopšte se ne šalje

    • Ne znam

    Correct Answer
    A. Čitljiv tekst
    Explanation
    The correct answer is "Čitljiv tekst". In the PAP protocol, the password is sent as readable text. This means that the password is not encrypted or encoded in any way, and can be easily understood by anyone who intercepts it. This lack of security in transmitting passwords is a vulnerability that can be exploited by attackers.

    Pristup transmisionom medijumu koji se koristi u Eternet mrežama je:

    • Token bus

    • CSMA/CD

    • Token ring

    • CSMA/CA

    Correct Answer
    A. CSMA/CD
    Explanation
    CSMA/CD (Carrier Sense Multiple Access/Collision Detection) is the correct answer because it is the access method used in Ethernet networks. With CSMA/CD, devices on the network listen for carrier signals before transmitting data, and if two devices transmit at the same time and a collision occurs, they both stop transmitting and wait for a random amount of time before attempting to transmit again. This method helps to avoid data collisions and ensures efficient and fair access to the network medium.
