Which IPsec domain defines the payload formats, exchange types, and naming conventions for security information such as algorithms or policies?

• A. DOI
• B. ISAKMP
• C. Oakley
• D. IKE

Answer: (A)

ISAKMP is the framework that defines how IPsec negotiates security associations. It standardizes the formats of the payloads that can be carried in negotiation messages, the exchange types used to move through a negotiation, and the naming conventions for the security information like algorithms and policies. This makes interop possible between different vendors and implementations because everyone is speaking the same language for how negotiations are structured and described. Oakley focuses on the actual key-exchange algorithms that can be used within that framework, and IKE is the protocol that runs the negotiation using ISAKMP as its underlying framework. The option referencing DOI isn’t the domain that defines those negotiation structures and naming conventions, so ISAKMP is the correct fit for what’s being asked.
