Which of the following protocols operate at the network layer? (Select All that Apply)
Answer(s): A,B,C,E
Understanding the Network Layer:The network layer (Layer 3 of the OSI model) is responsible for end-to-end packet delivery, including routing and addressing. Protocols operating at this layer handle logical addressing and path determination.Explanation of Each Protocol:IPv6:The next-generation Internet Protocol, which operates at the network layer to provide addressing and routing for packets.ICMPv6:Internet Control Message Protocol version 6, used for error reporting and diagnostic functions in IPv6 networks. It operates at the network layer.IPv4:The current widely-used Internet Protocol, which operates at the network layer to provide addressing and routing for packets.OSPF:Open Shortest Path First is a dynamic routing protocol that operates at the network layer to exchange routing information between routers.ICMP:Internet Control Message Protocol, used for error reporting and diagnostic functions in IPv4 networks. It operates at the network layer.Conclusion:IPv6, ICMPv6, IPv4, and ICMP all operate at the network layer. OSPF is also correct because it is a routing protocol that works at Layer 3.
