Which of the following protocols operate at the network layer? (Select All that Apply)

  1. IPv6
  2. ICMPv6
  3. IPv4
  4. OSPF
  5. ICMP

Answer(s): A,B,C,E

Explanation:

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.
