Which statements describe the logical token-passing topology? (Choosetwo.)Network usage is on a first come, first serve basis.Computers are allowed to transmit data only when they possess a token.Data from a host is received by all other hosts.Electronic tokens are passed sequentially to each other.Token passing networks have problems with high collision rates.7.

What two things will happen if a router receives an ICMP packet whichhas a TTL value of 1 and the destination host is several hops away? (Choosetwo.)The router will discard the packet.The router will decrement the TTL value and forward the packet to the next routeron the path to the destination host.The router will send a time exceeded message to the source host.The router will increment the TTL value and forward the packet to the next router onthe path to the destination host.The router will send an ICMP Redirect Message to the source host.15. Refer to the exhibit.
