8. Define DNS.

DNS stands for Domain Name System which refers to the phonebook of the Internet. When users type domain names like ‘’ into web browsers then, DNS finds the correct IP address for those sites. After that, browsers use those addresses for communicating with origin servers or CDN edge servers for accessing website information.

9. Why it is important to deploy local DNS servers?

A local DNS server helps in providing the local mapping of domain names to IP addresses. For resolving the remote requests related to the domain names on your network, this also provides record details to remote DNS servers.

  • A non-authoritative restoration refers to a process in which the domain controller is restored. And after that, the Active Directory (AD) objects are brought up to date by replicating the latest version of those objects from other domain controllers in the domain.
  • On the other hand, an authoritative restore refers to an operation in which the data that has been restored supersedes the data existing on other domain controllers in the domain. However, while performing an authoritative restore, the current versions of objects in the Active Directory are overwritten by the versions of the objects which were restored.

20. What is the process of installing an application if MSI is not available?

For adding the application using the Software Installer, the dot ZAP text file can be used rather than the windows installer

21. What is tattooing in terms of Registry?

Tattooing in the registry can be defined as suggesting to the users that they can change and view the preference of the customers that are not stored in the Registry portions. Moreover, even if the group policy is removed or changed, the user preference will still remain in the registry.
