Broadcastova poziadavka protokolu ARP (ARP Query) sa posiela s cielovou adresou:
- A.
CC-CC-CC-CC-CC
- B.
AA-AA-AA-AA-AA
- C.
FF-FF-FF-FF-FF-FF
Correct Answer
C. FF-FF-FF-FF-FF-FFExplanation
The correct answer is FF-FF-FF-FF-FF-FF. This is the broadcast address in Ethernet, which means that the ARP query is sent to all devices on the network. When a device receives this broadcast, it will check if the target IP address in the ARP query matches its own IP address. If it does, the device will respond with its MAC address. By using the broadcast address, the ARP query ensures that all devices on the network receive the request and have the opportunity to respond.Rate this question:

Polozka TTL v hlavicke IPv4 paketu znamena:
- A.
Priorita paketu
- B.
Zivotnost paketu
- C.
Ciel paketu
- D.
Zdroj paketu
Correct Answer
B. Zivotnost paketuExplanation
The TTL (Time to Live) field in the IPv4 packet header represents the remaining time that a packet is allowed to exist in the network. It is decremented by each router that forwards the packet, and if it reaches zero, the packet is discarded. This mechanism prevents packets from circulating indefinitely in the network. Therefore, the correct answer is "Zivotnost paketu" which means "Packet lifetime" in English.Rate this question:

Pri prenose hlasu v IP sieti sa uprednostnuje transportny protokol TCP pred UDP.
- A.
Pravda
- B.
Nepravda
Correct Answer
B. NepravdaExplanation
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.Rate this question:

Protokol TCP vnima udaje z aplikacnej vrstvy len ako prud bajtov bez vnutornej struktury
- A.
Pravda
- B.
Nepravda
Correct Answer
A. PravdaExplanation
The given statement is true. TCP (Transmission Control Protocol) is a transport layer protocol that is responsible for establishing a reliable and error-free connection between two devices on a network. It treats data from the application layer as a stream of bytes without any internal structure. TCP breaks this stream into smaller segments and adds necessary information, such as sequence numbers and checksums, to ensure the reliable delivery of data. Therefore, TCP does not concern itself with the internal structure or format of the data being transmitted.Rate this question:

Ktore protokoly transportnej vrstvy mozeme pouzit pri vytvoreni a pouzivani socketu?
- A.
TCP
- B.
HTTP
- C.
XML
- D.
IP
- E.
UDP
Correct Answer(s)
A. TCP
E. UDPExplanation
TCP and UDP are both transport layer protocols that can be used for creating and using sockets. TCP (Transmission Control Protocol) provides reliable and ordered delivery of data with error checking and flow control mechanisms. UDP (User Datagram Protocol) is a lightweight protocol that offers faster but unreliable delivery of data without error checking or flow control. HTTP (Hypertext Transfer Protocol) and XML (eXtensible Markup Language) are not transport layer protocols, but application layer protocols used for communication over the internet. IP (Internet Protocol) is a network layer protocol responsible for addressing and routing packets.Rate this question:

Pri prenose hlasu v IP sieti sa uprednostnuje transportny protokol TCP pred UDP.
- A.
Pravda
- B.
Nepravda
Correct Answer
B. NepravdaExplanation
The statement is false. When it comes to voice transmission in an IP network, the UDP (User Datagram Protocol) is preferred over TCP (Transmission Control Protocol). This is because UDP is a connectionless protocol that provides faster transmission with lower latency, which is crucial for real-time applications like voice communication. TCP, on the other hand, is a reliable protocol that ensures data delivery but introduces more overhead and potential delays, making it less suitable for time-sensitive applications like voice transmission.Rate this question:

Ktory protokol pouziva internetove DNS-based adresovanie - URL?
- A.
SIP OSPF
- B.
SIP ARP
- C.
SIP USI
- D.
SIP URI
Correct Answer
D. SIP URIExplanation
The correct answer is SIP URI. SIP (Session Initiation Protocol) is a communication protocol used for initiating, modifying, and terminating interactive user sessions involving multimedia elements such as video, voice, instant messaging, and virtual reality. URI (Uniform Resource Identifier) is a string of characters that identifies a resource on the internet. In the context of DNS-based addressing, SIP URI is used to address and locate resources such as users, services, or devices in a SIP-based communication system.Rate this question:
