Microsoft Azure Fundamentals — Question 415

Which term represents the ability to increase the computing capacity of a virtual machine by adding memory or CPUs?

Answer options

• A. agility
• B. vertical scaling
• C. horizontal scaling
• D. elasticity

Correct answer: B

Explanation

The correct answer is B, vertical scaling, as it specifically refers to adding resources like memory or CPU to a single virtual machine. Option A, agility, pertains to the flexibility of IT services, while option C, horizontal scaling, involves adding more machines rather than increasing capacity of a single one. Option D, elasticity, refers to the ability to dynamically allocate resources based on demand, not specifically increasing capacity.
