Which option is the benefit of implementing an intelligent DNS for a cloud computing solution?
Click on the arrows to vote for the correct answer
A. B. C. D.B
Option B is the correct answer.
An intelligent DNS, also known as a global traffic manager, is a technology that manages and directs user requests to the most appropriate server or data center in a distributed computing environment. In the context of cloud computing, an intelligent DNS can provide several benefits, including:
A. It does not reduce the need for a backup data center: Implementing an intelligent DNS does not eliminate the need for a backup data center. A backup data center is essential for disaster recovery and business continuity purposes in case the primary data center fails or is unavailable.
B. It can redirect user requests to locations that are using fewer network resources: This is the primary benefit of implementing an intelligent DNS. The intelligent DNS can monitor the network and direct user requests to the server or data center that is using fewer network resources, such as bandwidth or CPU usage. This can help optimize the use of resources and reduce costs.
C. It enables the ISP to maintain DNS records automatically: This is not a benefit of implementing an intelligent DNS for a cloud computing solution. DNS record maintenance is the responsibility of the organization that owns the domain name, not the ISP.
D. It eliminates the need for a GSS: A Global Site Selector (GSS) is a hardware appliance that directs user requests to the most appropriate server or data center based on predefined rules. An intelligent DNS can perform the same function as a GSS, but it does not eliminate the need for a GSS in all cases. Some organizations may still require a GSS for certain applications or services.
In summary, implementing an intelligent DNS for a cloud computing solution provides the benefit of redirecting user requests to locations that are using fewer network resources. This can help optimize resource usage and reduce costs.
