An organization wishes to provide better security for its name resolution services. Which of the following technologies BEST supports the deployment DNSSEC at the organization?

LDAP (Lightweight Directory Access Protocol) is used for directory services and authentication lookups, not for securing DNS name resolution or supporting DNSSEC deployment.

TPM (Trusted Platform Module) is a hardware-based security chip used for storing cryptographic keys and ensuring platform integrity, but it does not directly support DNSSEC deployment for name resolution.

TLS (Transport Layer Security) best supports DNSSEC deployment by providing encrypted transport for DNS communications (DNS over TLS), which complements DNSSEC's data integrity and authentication mechanisms. While DNSSEC itself uses cryptographic signatures to validate DNS responses, TLS secures the communication channel, preventing eavesdropping and tampering during transit. Together, TLS and DNSSEC provide a comprehensive security solution for name resolution services.

SSL (Secure Sockets Layer) is a deprecated predecessor to TLS with known vulnerabilities and is no longer considered a best practice for securing communications, making TLS the preferred choice.

PW (Password) is a basic authentication mechanism that does not provide the cryptographic transport security or integrity verification needed to support DNSSEC deployment.
