Which command generates DNSSEC keys in BIND?

• A. dnssec-signzone
• B. dnssec-keygen
• C. dnssec-verify
• D. dnssec-dnskey

Answer: (B)

The command that generates DNSSEC keys in BIND is dnssec-keygen. This utility is specifically designed to create the various types of keys necessary for DNSSEC, including both the Zone Signing Key (ZSK) and the Key Signing Key (KSK). When you run dnssec-keygen, it produces key files that can be used later in the signing process of a zone, enabling the implementation of DNSSEC to secure DNS records against attacks such as cache poisoning and spoofing. This is essential for providing integrity and authenticity to DNS data, as DNSSEC adds digital signatures to DNS records. The other commands listed serve different purposes within the context of DNSSEC. For instance, dnssec-signzone is used to sign a zone with the keys generated by dnssec-keygen, while dnssec-verify checks the validity of DNSSEC signatures against the keys. dnssec-dnskey is used to manage DNSKEY records in the context of zone files. Each of these tools plays an important role in the overall operation of DNSSEC, but dnssec-keygen is the specific tool for generating the keys themselves.
