Microsoft 70-411 Exam – Q24

Your network contains an Active Directory domain named contoso.com. All DNS servers host a DNS zone named adatum.com. The adatum.com zone is not Active Directory-integrated. An administrator modifies the start of authority (SOA) record for the adatum.com zone. After the modification, you discover that when you add or modify DNS records in the adatum.com zone, the changes are not transferred to the DNS servers that host secondary copies of the adatum.com zone.

You need to ensure that the records are transferred to all the copies of the adatum.com zone. What should you modify in the SOA record for the adatum.com zone? To answer, select the appropriate setting in the answer area.
24a

Correct Answer:
Serial number
24b

Explanation:
The revision number of the zone file. This number increases each time a resource record in the zone changes. It is important that this value increases each time the zone is changed, so that either partial zone changes or the fully revised zone can be replicated to other secondary servers during subsequent transfers.
