0 — Test 340

Correct Answer: D. D. All of the mentioned
Explanation: The delay of each packet in a datagram network is different as each packet might take a different route to the destination. The delay includes the propagation delay and the processing delay that is induced at each stop/switch that the packet encounters in its journey.

Correct Answer: B. B. Queue
Explanation: When there are too many packets to be transmitted and the transmission line gets blocked while transmitting some packets, the remaining packets are stored in queue during delay and are served as first in first out. The delay is called as queuing delay.

Correct Answer: C. C. Increases
Explanation: Probability of the error in a transmitted block increases with the length of the block. Hence, the blocks should be as short as possible for ideal transmission with low possibility of an error.

Correct Answer: D. D. Delay is the same for all packets in a flow
Explanation: The delay of each packet in a datagram network is different as each packet might take a different route to the destination. This happens because there is no pre-decided route for the packets.

Correct Answer: D. D. Both ripv1 and ripv2
Explanation: Both RIPv1 and RIPv2 support a maximum hop count of 15 because they use 4-bits to store this value. RIPv1 uses classful routing whereas RIPv2 uses classless routing. The routing updates are broadcasted over the network. It notifies routers about the update so that they update their own routing tables.

Correct Answer: A. A. Every 30 seconds
Explanation: RIPv1 router broadcasts its routing table every 30 seconds by default. The broadcasted routing table can be used by other routers to find the shortest path among the network devices.

Correct Answer: C. C. The route is inaccessible
Explanation: You cannot have 16 hops on a RIP network by default, because the max default hops possible is 15. If you receive a route advertised with a metric of 16, this means it is inaccessible.

Correct Answer: D. D. 1
Explanation: 1 is the default administrative distance of Static Route. It is used by routers to select the best path when there are different routes to the same destination. It’s used only two different routing protocols are being used.

Correct Answer: B. B. Rip
Explanation: RIP gives a full route table update every 30 seconds. The broadcasted routing table can be used by other routers to find the shortest path among the network devices.

Correct Answer: C. C. 120
Explanation: The default administrative distance is the default count of numbers assigned to arbitrary routes to a destination. The default administrative distance of RIP is 120. It is used to find the shortest route amongst the number of paths available.
