1 Packets are destroyed if they get "lost" and keep traveling the internet without arriving at a destination.
What is parameter is evaluated to determine whether a packet should get destroyed?

2. What type of telephony control signaling uses the same circuit as the voice traffic? 

3. Name the software which sits below the application layer that is responsible for routing application remote 
procedure calls to the appropriate server.

4. What class does the IP address 193.222.18.207 belong to? 

5. If 193.222.18.207 is the IP address and .255.255.255.224 is the subnet mask. The subnet number is?

6. If 193.222.18.207 is the IP address and 255.255.255.224 is the subnet mask; name the host ID number.

7. When a router discards packets because it has received packets beyond Its storage capacity, the
router is engaged in an activity called XXXXXXX control.

8. Routers need to know whether their neighboring routers are still alive. This is accomplished by
having routers send periodic messages to each other. What is the name of that message?

9. When the ARP protocol broadcasts an IP address to all nodes on the network the matching node
responds with a ______________address.
