Practice question 176 of 506 · medium

A primary zone's host record changed, but one secondary continues serving its older data. Clients querying the primary get the new address. What should be investigated?

Choose the single best answer.

  1. A.Secondary transfer permissions, master reachability, and serial/transfer status
  2. B.Allow dynamic updates directly to the read-only secondary as the transfer repair
  3. C.Only client caches while ignoring the older authoritative secondary data
  4. D.Only the TTL while assuming it synchronizes the secondary database
Show the answer and explanation

✓ Correct answer

  • Secondary transfer permissions, master reachability, and serial/transfer status

Older data at the authoritative secondary points to its transfer path and state. Client caches do not explain that server's stored older records, and TTL is caching behavior rather than database synchronization. A secondary is read-only and cannot be repaired by treating it as the writable update authority.
