Explanation
P2V (Physical to Virtual) is a type of migration that converts a physical server into a virtual machine (VM).
P2V migration can help to move a bare-metal server to the cloud by creating an image of its disk and configuration and uploading it to a cloud platform that supports VM creation from custom images.

Explanation
Replacing the equipment is the best action to take when a piece of networking equipment is about to reach its end of support. End of support means that the vendor or manufacturer will no longer provide technical assistance, updates, patches, or fixes for the equipment, which can affect its functionality, performance, security, and compatibility. Replacing the equipment with a newer model that has ongoing support can prevent any issues or risks associated with using outdated equipment.

Explanation
The best way to restrict access to a set of sensitive files to a specific group of users is to change the file permissions and ownership of the files. File permissions and ownership are attributes that determine who can read, write, execute, or modify the files. By changing the file permissions and ownership, the systems administrator can grant or deny access to the files based on the user identity or group membership.

Explanation
Cloud bursting is a scalability model that allows a company to use a hybrid cloud environment to handle peak or unpredictable workloads. Cloud bursting involves using the private cloud to host the core or critical applications, and using the public cloud to provide additional or temporary resources when the demand exceeds the capacity of the private cloud .
Cloud bursting can help a company to:
Improve the availability and reliability of the applications by replicating them across multiple cloud platforms and locations .
Optimize the performance and efficiency of the applications by dynamically allocating and releasing resources based on the workload and traffic .
Reduce the cost and complexity of the IT infrastructure by leveraging the pay-as-you-go and on-demand models of the public cloud .

Explanation
