- D.
Izmene jednog bita sa vrednosti 0 na vrednost 1
Correct Answer
D. Izmene jednog bita sa vrednosti 0 na vrednost 1Explanation
When we want to divide a computer network into two smaller networks, it will result in changing one bit from the value 0 to the value 1 in the network mask. This is because the network mask is used to determine which part of an IP address belongs to the network and which part belongs to the host. By changing one bit from 0 to 1, we are altering the network portion of the IP address, effectively dividing the network into two smaller networks.Rate this question:

Iskljuciva disjunkcija je jedna od logickih operacija koje se koriste u radu sa Internet protokolom. Njenim koriscenjem se prvenstveno omogucava utvrdjivanje:
- A.
Broj skokova izmedju posiljaoca i primaoca
- B.
Pozicija na kojoj se bitovi dva niza razlikuju
- C.
Optimalne putanje izmedju vise mogucih
- D.
Komunikacione putanje (rute) koje treba iskljuciti kao moguce
Correct Answer
B. Pozicija na kojoj se bitovi dva niza razlikujuExplanation
The correct answer is "pozicija na kojoj se bitovi dva niza razlikuju" (the position at which the bits of two arrays differ). Exclusive disjunction, also known as XOR, is a logical operation that compares two binary values and returns true if and only if the values differ at a specific position. In the context of Internet protocol, this operation can be used to determine the position where the bits of two arrays differ, which can be useful for various purposes such as error detection or data comparison.Rate this question:

Vrednost porta ima bitsku duzinu:
- A.
48
- B.
16
- C.
8
- D.
128
- E.
32
Correct Answer
B. 16Explanation
The correct answer is 16 because the question is asking about the bit length of a port value. A bit is the basic unit of information in computing and can have a value of either 0 or 1. Therefore, when the answer says "16", it means that the port value has a bit length of 16, indicating that it can have 16 bits or binary digits.Rate this question:

Koriscenje prevodjenja mreznih adresa (engl. Network Address Translation, NAT) mora se koristiti za povezivanje clanova sledecih mreza sa Internetom:
- A.
192.168.0.0/16
- B.
172.16.0.0/12
- C.
128.0.0.0/8
- D.
16.0.0.0/8
- E.
224.0.0.0/4
- F.
10.0.0.0/8
Correct Answer(s)
A. 192.168.0.0/16
B. 172.16.0.0/12
F. 10.0.0.0/8Explanation
The given IP address ranges (192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8) are private IP address ranges that are commonly used for local network addressing. These addresses are not routable on the internet, so Network Address Translation (NAT) must be used to translate these private IP addresses to a public IP address in order to connect the members of these networks to the internet. The other IP address ranges (128.0.0.0/8, 16.0.0.0/8, 224.0.0.0/4) are not private IP address ranges and do not require NAT for internet connectivity.Rate this question:

Correct Answer
B. Mreznom interfejsuExplanation
Internet Protocol (IP) address and network mask are assigned to the network interface. The network interface is responsible for connecting the device to the network and handling the communication between the device and the network. Therefore, the IP address and network mask are configured on the network interface to enable the device to communicate with other devices on the network.Rate this question:

Podrazumevani transportni protokol koga koristi SMTP protokol je:
- A.
UDP
- B.
HTTP
- C.
POP3
- D.
IMAP
- E.
TCP
Correct Answer
E. TCPExplanation
SMTP (Simple Mail Transfer Protocol) is a protocol used for sending email messages over a network. The default transport protocol used by SMTP is TCP (Transmission Control Protocol). TCP provides reliable and ordered delivery of data packets, which is essential for the successful transmission of email messages. UDP (User Datagram Protocol) is a connectionless protocol that does not guarantee reliable delivery of data, making it unsuitable for SMTP. HTTP (Hypertext Transfer Protocol), POP3 (Post Office Protocol 3), and IMAP (Internet Message Access Protocol) are all application layer protocols that can be used for different purposes, but they are not the default transport protocol used by SMTP.Rate this question:
