Objective : Implementing, Managing, and Maintaining Name Resolution
SubObjective : Install and configure the DNS Server service
Single Answer Multiple Choice

 

You are your company’s network administrator. The network contains Windows XP Professional and Windows Server 2003 computers. A primary DNS server named DNS1 hosts an Active Directory-integrated zone named corp.com.

 

The research department for your company has created its own DNS server named DNS-Res. It hosts a primary zone named res.corp.com. It also hosts a secondary zone for corp.com. A secondary zone for res.corp.com has been created on DNS1. However, you notice that DNS zone transfer traffic for the res.corp.com zone is occurring too often.

 

You want to ensure that transfer of the res.corp.com zone data between DNS-Res and DNS1 only occurs every four hours and that retries only occur every hour if transfer is not successful. In addition, if the zone transfer has not occurred after seven days the zone data should expire.

 

What should you do?

 

A. In the corp.com zone’s Properties dialog box on DNS1, click the Start of Authority (SOA) tab.
Configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days.
B. In the corp.com zone’s Properties dialog box on DNS-Res, click the Start of Authority (SOA) tab. Configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days.
C. In the res.corp.com zone’s Properties dialog box on DNS1, Click the Start of Authority (SOA) tab. Configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days.
D. In the res.corp.com zone’s Properties dialog box on DNS-Res, click the Start of Authority (SOA) tab. Configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days.

 

Answer:
D. In the res.corp.com zone’s Properties dialog box on DNS-Res, click the Start of Authority (SOA) tab. Configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days.

 

Tutorial:
You should click the Start of Authority (SOA) tab in the res.corp.com zone’s Properties dialog box on DNS-Res and configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days. Any settings for a particular zone should be configured on the primary DNS server for that zone.

 

You should not click the Start of Authority (SOA) tab in the corp.com zone’s Properties dialog box on DNS-Res and configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days. Your concern is not with transfer traffic for the corp.com zone. It is with the res.corp.com zone.

 

You should not click the Start of Authority (SOA) tab in the corp.com zone’s Properties dialog box on DNS1 and configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days. Your concern is not with transfer traffic for the corp.com zone. It is with the res.corp.com zone.

 

You should not click the Start of Authority (SOA) tab in the res.corp.com zone’s Properties dialog box on DNS1 and configure the Refresh interval option for four hours, the Retry interval option for one hour, and the Expire after option for seven days. The settings for the res.corp.com zone should be configured at DNS-Res because this is the primary DNS server for that zone.
