The correct answer is "2-Way Handshake, Лозинка се шаље као чист текст". This is because the given characteristics of the PAP protocol include the use of a 2-Way Handshake, where a password is sent as plain text. This means that the password is not encrypted or protected during transmission.

Submit

151. За потврду успешно примљеног низа сегмената уобичајено се користи:

Explanation

The correct answer is "Кумулативна потврда - један ACK сегмент за примљени низ сегмената података, са ознаком првог сегмената из следеће групе сегмената." This means that for a successfully received array of segments, a cumulative acknowledgment (ACK) segment is typically used, indicating the first segment of the next group of segments.

Submit

152. Да бисе заштитили од појаве дупликата који би био најједноставнији метод?

Explanation

To protect against the occurrence of duplicates, the simplest method would be to increase the space for sequence numbers. This means that each packet would be assigned a unique sequence number, which would prevent any duplicates from being sent or received. By increasing the space for sequence numbers, there would be a larger range of numbers available, reducing the likelihood of duplicates occurring.

Submit

153. Уколико протокол за рутирање уради следеће акције: -Открије своје суседе и сазна њихове мрежне адресе -Измери кашњење, односно метрику до сваког суседа -Формира пакет који садржи информације које је сазнао -Пошаље овај пакет свим другим рутерима -Израчуна најкраћу путању ка сваком рутеру Ово је пример за:

Explanation

The given actions describe the process of a routing protocol discovering its neighbors, measuring the delay to each neighbor, forming a packet with the learned information, sending this packet to other routers, and calculating the shortest path to each router. This process aligns with the concept of routing based on link state protocols, which involve routers exchanging information about their network state to determine the best path for data transmission. Therefore, the correct answer is "Рутирањe помоћу протокола стања везe" (Routing based on link state protocols).

Submit

154. У некој мрежи, рутери X, Y и Z су повезани на исту Eтернет мрежу. Уколико се у тој мрежи користи протокол за рутирање са стањем везе:

Explanation

If the network uses a link-state routing protocol, the Ethernet network will be represented as a single artificial node. This means that the routers X, Y, and Z will treat the Ethernet network as a single entity and calculate the best path to it based on the link-state information. The other routers will not decrement the metric to the Ethernet network because it is considered as one entity. The delay between the three routers is considered negligible in this case.

Submit

155. Транспортна веза може да пређе у стање ESTABLISHED из следећих стања:

Explanation

The correct answer is SYN SENT because when a transport connection is in the SYN SENT state, it means that a connection request has been sent to the remote host, but a response has not yet been received. Once the response is received and acknowledged, the connection will transition to the ESTABLISHED state. The other states listed (FIN WAIT, IDLE, CLOSE) are not valid transitions to the ESTABLISHED state.

Submit

156. За одређену везу (путању):

Explanation

The correct answer is that the delay due to propagation time is constant. This means that the delay experienced by a signal traveling through a certain path remains the same regardless of other factors such as the size of the packet, the type of transmission medium, or the size of the receiving buffer.

Submit

157. На самом почетку сервер извршава следећу примитиву:

Explanation

The given sequence of actions represents the steps involved in establishing a TCP connection. The correct answer, "PASSIVE OPEN," indicates that the server is in the initial stage of establishing a connection and is waiting for a client to initiate communication. This means that the server is ready to receive connection requests from clients. The other options, such as "CLOSE," "FIN WAIT," and "ACTIVE OPEN," do not represent the initial stage of establishing a connection and are not relevant to the given sequence.

Submit

158. Транспортна целина може да пређе у стање CLOSED из следећих стања:

Explanation

The correct answer is FIN WAIT because when a transport connection is in the FIN WAIT state, it means that one end of the connection has sent a FIN (finish) packet to initiate the termination process. This state indicates that the connection is waiting for the other end to acknowledge the FIN packet and send its own FIN packet. Once both ends have sent and acknowledged the FIN packets, the connection will transition to the CLOSED state, indicating that the connection has been successfully terminated.

Submit

159. Kod stafetnog prenosa ramova:

Explanation

The correct answer is that error correction and flow control are performed on the receiver side. This means that the receiver is responsible for detecting and correcting errors in the transmitted data, as well as managing the flow of data to ensure that it is received correctly and in the proper order. This approach allows for more efficient and reliable communication, as errors can be corrected before they impact the integrity of the data and flow control ensures that the receiver can handle the incoming data at its own pace.

Submit

160. Ком слоју OSI референтног модела припада PPP протокол?

Explanation

The correct answer is "Слој везе" (Link Layer). The PPP protocol belongs to the Link Layer of the OSI reference model. This layer is responsible for the reliable transmission of data over a physical link, handling issues such as framing, error detection, and flow control. PPP (Point-to-Point Protocol) is commonly used for establishing a direct connection between two network nodes, such as a computer and a modem, or two routers. It provides a means for encapsulating and transmitting network layer protocols, such as IP (Internet Protocol), over a serial link.

Submit

161. Код алгоритма за рутирање са вектором раздаљине, које информације рутери размењују?

Explanation

The correct answer is "метрика и следећи рутер до дестинације" (metric and next router to the destination). This is because routing algorithms use metrics to determine the best path to a destination, and the next router in that path is essential for forwarding the data packets correctly.

Submit

162. Намена часовника за поновну успоставу везе је да:

164. Када се јавља ефекат малог прозора SWS (Silly window syndrome )?

Explanation

The Silly Window Syndrome (SWS) occurs when the receiving TCP entity's buffer is full and the interactive application reads byte by byte. This means that the receiving application waits for the buffer to be filled before reading the data. This causes inefficiency as the application could have read the data as soon as it arrived.

Submit

165. Адреса апликационог корисника је одређена једнозначно:

Explanation

The correct answer is "Паром транспортне и мрежне адресе" which translates to "Transport and network addresses determine the user's application address uniquely." This means that the combination of the transport and network addresses is used to uniquely identify the user's application address. The other options, such as MAC and network addresses or physical and network addresses, do not provide a unique identification of the user's application address.

Submit

167. Код хијерархијског рутирања:

Explanation

The correct answer states that the router knows the details of packet routing within the local region, while other regions are represented by a single record. This means that the router has knowledge of how to route packets within its own region but does not have detailed information about routing between regions, as it is represented by a single record.

Submit

168. Дистрибуирање пакета стања веза:

Explanation

The correct answer is "Врши се механизмом преплављивања. Проблеми са рестартовањем рутера и грешкама у пријему се решавају увођењем поља које означава старост пакета." This means that the distribution of link state packets is done through flooding mechanism, where the packets are sent to all routers in the network. This helps in resolving issues related to router restarts and errors in reception by introducing a field that indicates the age of the packet.

Submit

169. На самом почетку транспортна целина се налази у следећем стању:

Explanation

At the beginning, the transport entity is in the "CLOSE" state.

Submit

170. Мултиплексирање на доле на траспортном слоју користи се када:

Explanation

Multiplexing at the lower transport layer is used when one transport connection uses multiple network layer connections. This means that a single transport connection is divided into multiple network layer connections to increase efficiency and utilize available resources more effectively.

Submit

171. Kод метода редоследа,aко само један сегмент стигне касније или је примљен са грешком:

Explanation

The correct answer states that all segments that arrive after the segment with an error will be discarded, and the transmitter will have to resend all segments with a sequence number higher than the segment with an error. This means that if one segment arrives late or with an error, the receiver will not store any subsequent segments and the transmitter will have to retransmit them.

Submit

172. Када се примењује алгоритам за избегавање загушења онда се:

Explanation

The correct answer states that the congestion window is increased by one segment when an Ack segment arrives, but only after a time equal to one round-trip time (RTT) has elapsed. This means that the algorithm for congestion avoidance is applied with a delay, allowing enough time for the network to stabilize before increasing the congestion window.

Submit

Submit

178. За оцену квалитета путање до удаљене мреже протоколи за рутирање користе неке од следећих параметара:

Explanation

Protocols for routing use the number of hops, bandwidth range, and delay as parameters to assess the quality of a path to a remote network. The number of hops refers to the number of intermediate devices or routers that a packet must pass through to reach its destination. The bandwidth range represents the available network capacity along the path, while the delay measures the time it takes for a packet to travel from the source to the destination. By considering these parameters, routing protocols can determine the most efficient and reliable path for data transmission.

Submit

179. Транспортна целина може да пређе у стање ESTABLISHED из следећих стања:

Explanation

A transport endpoint can transition to the ESTABLISHED state from the LISTEN and SYN SENT states. In the LISTEN state, the endpoint is waiting for a connection request from a remote endpoint. In the SYN SENT state, the endpoint has sent a connection request to the remote endpoint and is waiting for a response. Both of these states involve the establishment of a connection, which is why the endpoint can transition to the ESTABLISHED state from them. The other states mentioned (CLOSED, FIN WAIT, ACTIVE OPEN) do not involve the establishment of a connection, so the endpoint cannot transition to the ESTABLISHED state from them.

Submit

180. Објављеним прозором пријемник реализује:

Explanation

The correct answer is "Мехнизам контроле тока пријемника" which translates to "Receiver current control mechanism" in English. This suggests that the published window implements a mechanism to control the current of the receiver.

Submit

183. Проблем погрешних и дуплираних секвенцних бројева LSP пакета се решава:

Explanation

The correct answer is "увођењем поља које означава старост пакета" (introducing a field that indicates the age of the packet). Introducing a field that indicates the age of the packet helps in resolving the issues of incorrect and duplicate sequence numbers in LSP (Link State Packet) packets. This field allows routers to determine the freshness of the packet and discard any outdated or duplicate packets, ensuring the accuracy and efficiency of the network.

Submit

184. Како се може превазићи проблем кружења сегмента по затварању везе?

Explanation

The transport link remembers the last sequence number used in the completed transport link and takes it into account when establishing a new link. This means that it avoids the problem of segment looping by keeping track of the sequence numbers and ensuring that they are not repeated in the new link.

Submit

185. Објављеним прозором реализује се контрола тока:

Explanation

The correct answer is "During data transmission on the receiver side." This means that the flow control is implemented during the process of transmitting data to the receiver. It ensures that the sender does not overwhelm the receiver with data, preventing data loss or congestion.

Submit

186. Шта се дешава ако предајник неколико пута започиње рад са хитним подацима пре него што пријемник обради све податке закључно са првим показивачем?

Explanation

If the transmitter starts transmitting emergency data multiple times before the receiver processes all the data, the new incoming pointer is written over the previous one. This means that there is only one pointer for emergency data on the receiver, and each new incoming pointer replaces the previous one.

Submit

187. Шта одређује административна дистанца?

Explanation

Административна дистанца се одређује на основу приоритета извора информације о рути. Када постоји више извора информације о рути, рутери користе приоритет да одлуче који извор информације је најпоузданији и најтачнији. На основу тога, рутери одређују административну дистанцу руте и користе је за одабир најбоље руте за прослеђивање података.

Submit

188. Код Диjкстра алгоритма, сваки чвор обележен је:

Explanation

The correct answer is "Удаљеношћу од изворног чвора" and "Ознаком чвора из кога се врши испитивање" because the Dijkstra algorithm calculates the shortest path from a source node to all other nodes in a graph. The distance from the source node is used to determine the priority of nodes in the algorithm, and the label of the node from which the examination is being performed helps keep track of the progress of the algorithm.

Submit

189. Намена часовника за ретрансмисију SYN сегмента је да

Explanation

The purpose of the clock for retransmission of SYN segments is to provide time between two attempts to establish and open a connection. This means that the clock allows for a delay between the first attempt to establish a connection and the second attempt, providing the necessary time for the process.

Submit

190. Алгоритом под називом успорени почетак (Slow start) ради на следећем принципу:

Explanation

The algorithm called Slow Start works based on the principle that the speed at which packets are inserted into the network is determined by the speed at which the destination returns acknowledgments.

Submit

191. Шта од следећег може да се јави у мрежама које нису конвергирале а у којим се користе протоколи са вектором удаљености?

Explanation

In networks that have not converged and use distance vector protocols, several issues can occur. One possible issue is having inconsistent entries in the routing tables, which means that different routers have different information about the network topology. This can lead to incorrect routing decisions and misrouting of traffic. Another issue is the presence of routing loops, where packets are continuously forwarded between routers without reaching their destination. This can cause significant delays and network congestion. Lastly, there can be inconsistent forwarding of traffic, where routers do not agree on the best path to forward packets, leading to inefficient routing.

Submit

193. Очекује се да се вредност RTT мења у времену у зависности од:

Explanation

The value of RTT is expected to change over time depending on the path the segment takes. This means that the round-trip time can vary based on the specific route that the network packet travels from the source to the destination. Different paths may have different levels of congestion, latency, or other factors that can affect the RTT. Therefore, the path taken by the segment is a key factor in determining the value of RTT.

Submit

194. Код прослеђивања реверзном путањом (reverse path forwarding):

Explanation

The reverse path forwarding algorithm ensures that a router sends an acknowledgement in the opposite direction of where the emission packet came from. Route reply packets are also sent in the opposite direction of their arrival path. If a packet arrives on the line typically used for sending packets to the source of emission, it is not discarded. This algorithm is used to make sure that packets are properly received and acknowledged in a network.

Submit

195. За одређену везу (путању):

Explanation

The correct answer is "Кашњење због преноса зависи од величине пакета" (Delay due to transmission depends on the size of the packet). This means that the delay in transmission is influenced by the size of the data packet being transmitted. Larger packets may take longer to transmit, resulting in increased delay. Smaller packets, on the other hand, may be transmitted more quickly, leading to reduced delay.

Submit

196. За рутирање вишеструким усмеравањем је неопходно разрадити:

Explanation

The correct answer is the way to create groups, create and delete them, and the way applications join and leave groups. This is because the question is asking for the necessary steps to be taken for multi-routing, and creating and managing groups is an essential part of this process. Additionally, the ability for applications to join and leave groups is crucial for effective multi-routing.

Submit

199. Шта је од наведеног карактеристика протокола за рутирање са стањем везе?

Explanation

The correct answer options state that the characteristics of a link-state routing protocol include enabling the division of routers into hierarchical areas, having less frequent periodic updates compared to distance vector protocols, and sending updates after a change in topology. These characteristics are commonly associated with link-state routing protocols, such as OSPF (Open Shortest Path First), which use a database of link-state information to determine the best path for routing.
