What is DNSSEC used for?

    Correct Answer: B

    DNSSEC, which stands for Domain Name System Security Extensions, is used to provide cryptographic authentication of DNS zones. It helps to ensure that the responses to DNS queries are authentic and have not been tampered with. By doing this, DNSSEC protects against certain types of attacks, such as cache poisoning, where an attacker could provide false DNS information. DNSSEC does not encrypt DNS queries or answers; it ensures the integrity and authenticity of DNS data.
