Which parameter is configured with a TTL of 4800 seconds during DNSSEC configuration?

During the DNSSEC configuration process, the Time to Live (TTL) parameter for both DS (Delegation Signer) and DNSKEY records can be set, and it is common practice to configure them to have the same TTL value for consistency and management efficiency. A TTL of 4800 seconds indicates the duration for which the DNS records are valid and can be cached by DNS resolvers.

By setting both DS and DNSKEY records with a TTL of 4800 seconds, it ensures that changes to these records are propagated in a timely manner while also allowing for sufficient caching to reduce the load on the DNS infrastructure. If either record were to change, resolvers would need to refresh their cache in accordance with this TTL setting.

While it's typical to configure both records with the same TTL, it's still important to acknowledge that each record type serves different purposes in the DNSSEC framework. DNSKEY records are used to sign the zone, while DS records establish a chain of trust by linking a child zone to its parent. Thus, setting them to the same TTL reinforces their relationship and simplifies DNS management.

In summary, configuring a TTL of 4800 seconds for both DS and DNSKEY records during DNSSEC setup ensures that both types of records can be updated effectively
