CCNA: Cisco Certified Network Associate — Question 1037

How does IPsec provide secure networking for applications within an organization?

Answer options

• A. It takes advantage of FTP to secure file transfers between nodes on the network.
• B. It provides GRE tunnels to transmit traffic securely between network nodes.
• C. It enables sets of security associations between peers.
• D. It leverages TFTP providing secure file transfers among peers on the network.

Correct answer: C

Explanation

The correct answer is C because IPsec establishes security associations that define the parameters for secure communication between peers. Options A and D incorrectly suggest that IPsec relies on FTP and TFTP for file transfer security, which is not accurate. Option B mentions GRE tunnels, which do not provide the encryption and security capabilities that IPsec offers.
