Correct Answer
A. Bez uspostave vezeExplanation
The correct answer is "Bez uspostave veze" which means "Without establishing a connection" in English. This refers to the fact that the IP protocol operates in a connectionless manner, where each packet is treated independently and can take different routes to reach its destination. Unlike protocols with connection-oriented communication, such as TCP, IP does not require a prior establishment of a connection between sender and receiver. Instead, it relies on the best-effort delivery model, where packets are sent without any guarantee of delivery or order.Rate this question:

The correct answer is "Pronašla nepoznata MAC adresa stanice, kada je poznata njena IP adresa" which translates to "To find the unknown MAC address of a station when its IP address is known." ARP (Address Resolution Protocol) is used to map an IP address to a MAC address on a local network. When a device wants to communicate with another device on the same network, it needs to know the MAC address of the destination device. ARP helps in resolving this mapping by sending an ARP request to the network, asking for the MAC address of the device with a specific IP address.Rate this question:

- D.
Vreme za koje će paket biti isporučen odredištu
Correct Answer
A. Vreme trajanja paketa, i vrednost se pri svakom prolazu kroz ruter dekrementira za 1Explanation
TTL stands for Time to Live. It represents the maximum amount of time or number of hops that a packet can take before it is discarded. Each time the packet passes through a router, the TTL value is decremented by 1. This ensures that if a packet gets stuck in a loop or takes too long to reach its destination, it will eventually be discarded to prevent network congestion. Therefore, the correct answer is "Vreme trajanja paketa, i vrednost se pri svakom prolazu kroz ruter dekrementira za 1" which means "Packet lifetime, and the value is decremented by 1 at each router passage."Rate this question:

This happens when a broadcast packet circulates endlessly in the loop, causing a flood of broadcast traffic that overwhelms the network. This can lead to network congestion, performance degradation, and even network failure.Rate this question:

- A.
Izvorišne adrese i oznake toka
- B.
Oznake toka, izvorišne i odredišne adrese
- C.
Odredišne adrese i oznake toka
- D.
Protok je jedinstveno definisan oznakom toka
Correct Answer
B. Oznake toka, izvorišne i odredišne adreseExplanation
The correct answer is "Oznake toka, izvorišne i odredišne adrese." This is because the sentence "Tok IPv6 protokola jedinstveno definiše" suggests that the IPv6 protocol uniquely defines something. Among the given options, only "Oznake toka, izvorišne i odredišne adrese" includes all three elements mentioned in the sentence, which are "Oznake toka" (flow labels), "izvorišne adrese" (source addresses), and "odredišne adrese" (destination addresses). Therefore, this option is the correct answer.Rate this question:

- D.
Ruteri moraju imati mogućnost zamene identifikatora veze u izlaznim paketima
Correct Answer
D. Ruteri moraju imati mogućnost zamene identifikatora veze u izlaznim paketimaExplanation
The correct answer states that routers must have the capability to replace link identifiers in outgoing packets. This means that routers need to be able to modify the identifiers of the links through which the packets are being sent. This is important for routing in subnets with virtual circuits because it allows the routers to properly direct the packets to their intended destinations. Without the ability to replace link identifiers, the routers would not be able to effectively route the packets in the network.Rate this question:

- C.
Polje DF u IP zaglavlju se postavi na vrednost 0
- D.
Polje MF u IP zaglavlju se postavi na vrednost 1
Correct Answer
A. Polje DF u IP zaglavlju se postavi na vrednost 1Explanation
To indicate to the router that packet fragmentation should not be performed, the DF (Don't Fragment) field in the IP header is set to a value of 1. This tells the router not to fragment the packet and instead discard it if it cannot be forwarded without fragmentation. The MF (More Fragments) field is not relevant in this case as it is used to indicate whether there are more fragments of the original packet.Rate this question:

- C.
Eternet ram nema TTL polje IP paketa
- D.
Ne znam
Correct Answer
C. Eternet ram nema TTL polje IP paketaExplanation
Ethernet RAM (Random Access Memory) not having a TTL (Time to Live) field in IP packets can lead to the emission storm. The TTL field in an IP packet specifies the maximum number of hops (routers) the packet can travel before being discarded. Without this field, packets can circulate indefinitely in the network, causing a broadcast storm.Rate this question:

- D.
Parom fizičke adrese i MAC adrese
Correct Answer
A. Parom transportne i mrežne adreseExplanation
The correct answer is "Parom transportne i mrežne adrese." This means that the address of the application user is uniquely determined by the pair of transport and network addresses. In networking, the transport address refers to the specific port number used by the application, while the network address refers to the IP address of the device. Together, these two addresses uniquely identify the application user.Rate this question:

Kod IPv6 protokola, brodkast je na identican način implementiran kao i kod IPv4 protokola?
- A.
Tačno
- B.
Netačno
Correct Answer
B. NetačnoExplanation
The correct answer is "Netačno" (False). In the IPv6 protocol, the implementation of broadcast is not identical to the IPv4 protocol. In IPv4, broadcast is achieved by sending a packet to the broadcast address, which is a special address that represents all devices on the network. However, in IPv6, the concept of broadcast is replaced by multicast, where packets are sent to a specific group of devices instead of all devices on the network. Therefore, the implementation of broadcast is different in IPv6 compared to IPv4.Rate this question:

Kod protokola IPv4, ukoliko je paket podeljen na više delova, vrednost polja identifikacija:
- A.
Vrednost se uvećava za 1 za svaki deo paketa
- B.
Ima istu vrednost u svakom od delova paketa
- C.
Vrednost se umanjuje za 1 za svaki deo paketa
- D.
Vrednost je 0 u svakom delu paketa
Correct Answer
B. Ima istu vrednost u svakom od delova paketaExplanation
In the IPv4 protocol, if a packet is divided into multiple parts, the value of the identification field remains the same in each part of the packet. This allows the receiver to identify and reassemble the fragmented parts of the packet correctly. By having the same identification value, the receiver can recognize that the fragmented parts belong to the same original packet.Rate this question:
