defines the communication in an IP-based network. It provides end-to-end connectivity
specifying how data should be formatted, addressed, transmitted, routed and received at the
destination. This functionality has been organized into four abstraction layers which are used to
sort all related protocols according to the scope of networking involved.

A. Transport layer
B. Network Access layer
C. Internet layer
D. Application layer Answer(s):
Firewall is an IP packet filter that enforces the filtering and security policies to the flowing
network traffic. Using firewal s in IPv6 is stil the best way of protection from low level attacks at
the network and transport layers. Which one of the following cannot handle routing protocols
A. "Internet-router-firewall-net architecture"
B. "Internet-firewall-router-net architecture"
C. "Internet-firewall/router(edge device)-net architecture"
D. "Internet-firewall -net architecture" Answer(s):
