IKE is used in Cisco IPSec standards and provides what?

• A. Used in Cisco IPSec standards and provides strong authentication
• B. A protocol for securing email
• C. A tunneling protocol for web traffic
• D. A transport protocol for file transfer

Answer: (A)

IKE (Internet Key Exchange) is the mechanism that negotiates and establishes the cryptographic keys and security associations that IPsec uses to protect traffic. Its primary role is to provide strong authentication between the communicating devices—typically through pre-shared keys or digital certificates—and to securely exchange the keys and parameters that IPsec will apply to encrypt and protect data. This authentication and key management is what lets IPsec form trusted tunnels. It isn’t a protocol for securing email, a tunneling protocol for web traffic, or a transport protocol for file transfer—the functions of those are handled by other standards and protocols. So the correct interpretation is that IKE provides strong authentication within Cisco IPSec standards.
