Many tools and technologies are available for securing or monitoring data in transit within a data center, whether it is a traditional data center or a cloud. Which of the following is NOT a technology for securing data in transit? 

Answer options:

A. VPN
B. TLS
C. DNSSEC
D. HTTPS

C

DNSSEC is an extension of the normal DNS protocol that enables a system to verify the integrity of a DNS query resolution by signing it from the authoritative source and verifying the signing chain. It is not used for securing data transmissions or exchanges. HTTPS is the most common method for securing web service and data calls within a cloud, and TLS is the current standard for encrypting HTTPS traffic. VPNs are widely used for securing data transmissions and service access.
