Question

which of the following processes is used for adding additional resources to the users application?
a scaling
b fault tolerance
c alerting
d availability zone

Explanation:

Scaling refers to the process of adjusting resources (such as computing power, storage) in a system. When more resources are added to meet increased demand (like more users accessing an application), it is called scaling up (vertical scaling) or scaling out (horizontal scaling). Fault tolerance is about a system's ability to continue operating properly in the event of component failures. Alerting is about notifying administrators or users when certain conditions (e.g., resource thresholds being crossed) occur. An availability zone is a physical location within a region in cloud computing that has independent power, cooling, etc.

Answer:

A. Scaling
