    Protokol UDP je (vyberte 2) :

    • Spolahlivy

    • Nespojovany

    • Nespolahlivy

    • Spojovany

    Correct Answer(s)
    A. Nespojovany
    A. Nespolahlivy
    Explanation
    The correct answer is "nespojovany, nespolahlivy" because UDP (User Datagram Protocol) is an unreliable and connectionless transport protocol. It does not provide any guarantees for the delivery or ordering of packets, making it suitable for applications that prioritize speed over reliability, such as real-time streaming or online gaming.

    Ako moze TCP server efektivne spracovat poziadavky viacerych klientov sucasne?

    • Vytvorenie potomkovych procesov pre kazdeho klienta

    • Operacny system nepodporuje obsluhu viacerych klientov sucasne pre protokol TCP.

    • Pre sucasne spracovanie viacerych klientov neexistuju ziadne programove prostriedky

    • Pouzitie viacerych vlakien

    Correct Answer(s)
    A. Vytvorenie potomkovych procesov pre kazdeho klienta
    A. Pouzitie viacerych vlakien
    Explanation
    The TCP server can effectively process requests from multiple clients simultaneously by either creating child processes for each client or by using multiple threads. By creating child processes for each client, the server can handle each client's request independently without interfering with other clients. Similarly, by using multiple threads, the server can allocate separate threads to handle each client's request concurrently, allowing for efficient processing of multiple clients at the same time.

    Pri asymetrickom sifrovani vlastnik sukromneho kluca nedesifruje spravu

    • Pravda

    • Nepravda

    Correct Answer
    A. Nepravda
    Explanation
    In asymmetric encryption, the owner of the private key is actually able to decrypt the message. This is because asymmetric encryption uses a pair of keys - a public key for encryption and a private key for decryption. The public key is used by anyone who wants to send an encrypted message to the owner of the private key. Therefore, the statement "the owner of the private key does not decrypt the message" is false.

    Adresu siete v protokole IP je:

    • Kazda ina adresa s danym predcislim

    • Najvyssia adresa s danym predcislim

    • Najnizsia adresa s danym predcislim

    Correct Answer
    A. Najnizsia adresa s danym predcislim
    Explanation
    The correct answer is "Najnizsia adresa s danym predcislim." This means that the network address in the IP protocol is the lowest address with a given prefix. In IP addressing, the network address is used to identify the network to which a device belongs. It is obtained by setting all host bits to 0 in the IP address. The lowest address with a given prefix is the one where all host bits are set to 0, indicating the network address.

    Pri prenose hlasu v IP sieti sa uprednostnuje transportny protokol TCP pred UDP.

    • Pravda

    • Nepravda

    Correct Answer
    A. Nepravda
    Explanation
    Pri prenose hlasu v IP sieti sa uprednostňuje transportný protokol UDP pred TCP. UDP je vhodnejší pre prenos hlasu, pretože je rýchlejší a menej spoľahlivý. Pri prenose hlasu je dôležité, aby pakety dorazili v čo najkratšom čase, a nie je tak dôležité, či všetky pakety dorazili v správnom poradí. TCP je spoľahlivejší protokol, ktorý kontroluje doručenie paketov a ich poradie, čo môže spôsobiť oneskorenie a zvýšiť oneskorenie pri prenose hlasu.

    Viacbajtove hodnoty (napr. IP adresa a port v prislusnych hlavickach) prenesene cez siet a precitane zo socketu na lokalnej stanici pouzivaju poradie bajtov zname ako:

    • Little-endian

    • Direct-endian

    • Reverse-endian

    • Big-endian

    Correct Answer
    A. Big-endian
    Explanation
    The correct answer is Big-endian. Big-endian is a byte order in which the most significant byte is stored first and the least significant byte is stored last. In this byte order, the higher-order bytes are stored at lower memory addresses. This is commonly used in network protocols such as TCP/IP.

    Standard protokolu SIP bol navrhnuty pre minimalnu skalovatelnost.

    • Pravda

    • Nepravda

    Correct Answer
    A. Nepravda
    Explanation
    The statement is false. The SIP protocol was designed specifically for its scalability. It allows for easy addition of new users and devices without causing disruptions or performance issues. Therefore, the correct answer is false.
