Identity with Windows Server 2016 — Question 42

Your network contains an Active Directory forest named contoso.com. Users frequently access the website of an external partner company. The URL of the website is http://partners.adatum.com.
The partner company informs you that it will perform maintenance on its Web server and that the IP addresses of the Web server will change.
After the change is complete, the users on your internal network report that they fail to access the website. However, some users who work from home report that they can access the website.
You need to ensure that your DNS servers can resolve partners.adatum.com to the correct IP address immediately.
What should you do?

Answer options

• A. Run dnscmd and specify the CacheLockingPercent parameter.
• B. Run Set-DnsServerGlobalQueryBlockList.
• C. Run ipconfig and specify the Renew parameter.
• D. Run Set-DnsServerCache.

Correct answer: D

Explanation

The correct answer is D because running Set-DnsServerCache clears the existing DNS cache, allowing the DNS server to retrieve the updated IP address for partners.adatum.com. Options A and B do not address the immediate need to refresh the DNS resolution. Option C is related to renewing DHCP leases and does not affect DNS cache.
