• To set up a secure encrypted channel for Phase 2

• To verify the integrity of data packets

• To encrypt data packets

Which encryption algorithm is commonly used to ensure data confidentiality in IPSec?

• AES

• RSA

• DES

• SHA

What is the primary function of Authentication Header (AH) in IPSec?

• Establishes secure connections between endpoints

• Provides encryption for data packets

• Ensures data confidentiality

• Calculates a hash of the entire IP packet for integrity protection

In a site-to-site VPN, what does the tunnel mode of ESP provide?

• Secure key exchange using Diffie-Hellman

• Encryption for the entire IP packet

• Authentication of communicating parties

• Integrity protection for data packets

What is the purpose of Diffie-Hellman Key Exchange in IPsec?

• To establish secure communication between network gateways

• To provide authentication and integrity without encryption
