Question
Each IP packet is sent with its header bits set to indicate that no fragmentation is allowed to be performed. If a router receives a packet that is too large, it generates an error packet, returns it to the source, and drops the packet. What is this strategy called?
Dynamic Fragmentation
Fixed Fragmentation
Path MTU Discovery
IP Packet Discovery
There are five optional fields for the IP version 4 protocol. What is NOT an optional field?
Security
Record route
Control
Timestamp
The problem of running out of IP addresses is not a theoretical one that might occur at some point in the distant future. It is happening right here and right now. The long-term solution is for the whole Internet to migrate to IPv6, which has 128-bit addresses. This transition is slowly occurring, but it will be years before the process is complete. To get by in the meantime, a quick fix was needed. The quick fix that is widely used today came in the form of ______________.
IP Extension
Address Extension
Network Address Translation
IP Translation
Each router that is connected to two or more areas is called a(n) ___________. It must also be part of the backbone.
Internal Router
Boundary Router
Backbone Router
Area Border Router
A.Dynamic Fragmentation
B.Fixed Fragmentation
C.Path MTU Discovery
D.IP Packet Discovery
