Which statement about DNS secondary zones is true?

The zone can be updated by client computers
Zone transfers are automatically enabled
Secondary zones are read-only
Secondary zones can be updated via DHCP

The correct answer is: Secondary zones are read-only

Secondary zones are read-only in the context of DNS management. This means that while they can provide redundancy and improve the load distribution of DNS requests, they cannot be directly modified by administrators or client computers. Instead, the information in a secondary zone is obtained through zone transfers from a primary zone. Additionally, the primary purpose of a secondary zone is to facilitate data redundancy and fault tolerance. When a secondary zone is created, it essentially acts as a copy of the primary zone, holding the same information for DNS records but in a read-only format. This design ensures that if the primary server becomes unavailable, DNS queries can still be resolved through the secondary servers, thus maintaining uptime and reliability. The other statements regarding secondary zones are not accurate. Secondary zones do not allow direct updates from client computers or through DHCP settings, and while zone transfers can be set up, they are not automatically enabled without the appropriate configuration.
