This question requires that you evaluate the underlined text to determine if it is correct.
Redundant Microsoft Azure applications are able to meet increased demand with consistent results in acceptable time windows.
Review the underlined text. If it makes the statement correct, select “No change is needed”. If the statement is incorrect, select the answer choice than makes the statement correct.
A . No change is needed
B . Highly Available
C . Fault Tolerant
D . Scalable
Answer: D
Explanation:
Scalable applications are able to meet increased demand with consistent results in acceptable time windows. When a system is scalable, it scales horizontally or vertically to manage increases in load while maintaining consistent performance. In basic terms, horizontal scaling adds more machines of the same size (processor, memory, bandwidth) while vertical scaling increases the size of the existing machines.
