Your network contains a DNS zone for contoso.com.
All servers register their host names in DNS by using dynamic updates.
The network contains a server named server1.contoso.com.
From a computer named Computer1 that runs Windows 7, you successfully resolve serverl.contoso.com to an IP address.
You change the IP address of serverl.contoso.com.
From Computer1, you discover that serverl.contoso.com still resolves to the old IP address.
You successfully connect to serverl.contoso.com by using the new IP address.
You need to ensure that you can immediately resolve serverl.contoso.com to the new IP address.
What should you do on Computer1?
A. Restart the Network Location Awareness service.
B. Run dnscacheugc.exe.
C. Restart the Computer Browser service.
D. Restart the DNS Client service.
Answer: D
Explanation: Have you ever had an issue where you continually get DNS errors while trying to browse, but another computer on the same network is working just fine? The problem is most likely that you need to reload your DNS cache on that machine.
You can tackle this problem two ways, first by just clearing the cache, but also by restarting the DNS client service, which handles caching of DNS lookups.
Either:
* Clear DNS Cache ipconfig /flushdns
or
* net stop dnscache net start dnscache

Q35. - (Topic 3)
You have a server that runs Windows Server 2008 R2.
You create a new quota template. You apply quotas to 100 folders by using the quota template. You need to modify the quota settings for all 100 folders.
You must achieve this goal by using the minimum amount of administrative effort.
What should you do?
A. Modify the quota template.
B. Delete and recreate the quota template.
C. Create a new quota template. Modify the quota for each folder.
D. Create a file screen template. Apply the file screen template to the root of the volume that contains the folders.
Answer: A
Explanation:
When you make changes to a quota template, you have the option of extending those changes to quotas that were created from the original quota template. You can choose to modify only those quotas that still match the original template or all quotas that were derived from the original template, regardless of any modifications that were made to the quotas since they were created. This feature simplifies the process of updating the properties of your quotas by providing one central point where you can make all the changes.
To edit quota template properties 1- In Quota Templates, select the template that you want to modify. 2- Right-click the quota template, and then click Edit Template Properties (or in the Actions pane, under Selected Quota Templates, select Edit Template Properties). This opens the Quota Template Properties dialog box. 3- Perform all necessary changes. The settings and notification options are identical to those that you can set when you create a quota template. Optionally, you can copy the properties from a different template and modify them for this one. 4- When you are finished editing the template properties, click OK. This will open the Update Quotas Derived from Template dialog box. 5- Select the type of update that you want to apply:
-If you have quotas that have been modified since they were created with the original template, and you do not want to change them, select Apply template only to derived quotas that match the original template. This option will update only those quotas that have not been edited since they were created with the original template.
-If you want to modify all existing quotas that were created from the original template, select Apply template to all derived quotas.
-If you want to keep the existing quotas unchanged, select Do not apply template to derived quotas.
6- Click ok.
