Question

Difficulty: MediumHigh Availability, Scalability, and Elasticity

A financial company is moving a transaction-processing system to Azure. The system must automatically provision additional compute resources to handle temporary spikes in transaction volume and deprovision them when the spikes subside.

Is the statement below true or false?

The ability of this system to automatically adjust its resource capacity in response to dynamic demand changes is defined as high availability.

Answer: Answer

Answer

False
The correct answer is False because the capability to dynamically and automatically adjust resource capacity to match changing demand is called elasticity, not high availability.

Step-by-Step Solution

1
Analyze the scenario requirements.
The system dynamically adds and removes compute resources automatically in response to transaction volume spikes.
This establishes that the core capability being tested is the automated adjustment of resource capacity.
2
Define the cloud concept of elasticity.
Elasticity is the capability of a cloud environment to automatically adapt resource allocation to match current demand dynamically.
To verify if the statement's terminology matches the behavior described.
3
Define the cloud concept of high availability.
High availability is the capability to ensure that services remain operational and accessible, typically through redundancy and fault tolerance, with minimal downtime.
To distinguish high availability from elasticity.
4
Evaluate the validity of the statement.
The statement incorrectly defines elasticity as high availability, making the statement false.
To determine the final true/false answer.
