Exam 70-742 topic 1 question 10 discussion

Actual exam question from Microsoft's 70-742
Question #: 10
Topic #: 1
[All 70-742 Questions]

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?

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

You can configure cache locking with the dnscmd tool by performing the following procedure: 1. Launch an elevated command prompt. 2. Run the following command: dnscmd /Config /CacheLockingPercent 3. Restart the DNS service to apply the changes. Alternatively, you can use the Windows PowerShell Set-DnsServerCache –LockingPercent cmdlet to set this value. For example: Set-DnsServerCache –LockingPercent

I think the answer is correct. However one could argue that if you set your cache locking (answer A) to zero, or something very low, it will accomplish the same?

The Set-DnsServerGlobalQueryBlockList cmdlet changes settings of a global query block list on a Domain Name System (DNS) server. This cmdlet replaces all names in the list of names that the DNS server does not resolve with the names that you specify.

I believe this is a 70-741 question? This seems to be a DNS issue.
