Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types?

Traceroute sends messages with low TTL values to make the routers send back a TTL Exceeded message.
Specifically, a traceroute command begins by sending several packets (usually three), each with the header TTL field equal to 1.
When that packet
arrives at the next router, the router decrements TTL to 0 and discards the packet.
The router then sends the sender the TTL Exceeded message, which identifies the router's IP address to the traceroute command.
To find all the routers in the path, and finally confirm that packets flow all the way to the
destination host, the traceroute command sends a small set of packets with TTL=1, then a
small set with TTL=2, then 3, 4, and so on, until the
destination host replies.
