JNCIA-SEC: Juniper Networks Certified Associate – Security — Question 12

What does IPsec use to negotiate encryption algorithms?

Answer options

• A. AH
• B. TLS
• C. IKE
• D. ESP

Correct answer: C

Explanation

The correct answer is C, IKE, which stands for Internet Key Exchange. IKE is responsible for negotiating the security associations and the encryption algorithms used in IPsec. The other options, such as AH and ESP, are protocols within IPsec but do not handle the negotiation process, while TLS is a separate security protocol unrelated to IPsec's negotiation functions.
