9. How does an IPv4 router process data packets?

a) It transmits them as fast as they come in because the input must equal the output.

b) It deletes packets that do not have priority code above a specified level.

c) It quelues packets, then transmits them in the order in which they arrived.

d) It gives first priority to time-sensitive packets and delays other packets.

e) It rejects packets containing time-sensitive data.

10. How does a SONET circuit switch process SONET frames?

a) It transmits them as fast as they come in because the input must equal the output.

b) It deletes packets that do not have priority code above a specified level.

c) It queues packets, then transmits them in the order in which they arrived.

d) It gives first priority to time-sensitive packets and delays other packets.

e) It rejects packets containing time-sensitive data.

Solution

9. IPv4 router is a packet switching network.it allows the packets buffered from main memory. the main advantage of packet switching ,the first packet of a multipacket message can be forwarded before the 2nd packet has fully arraived reducing delay and improving throughput.so it tramsmits the data packets by queues packets ,then transmits them in the order in which they arrived.

10.sonet is a circuit switching network. in circuit switching a dedicated path will be established betwwen the source and destination networks so it transmits the sonet frames as fast aas they come in.
