Which of these is a key benefit of cloud scalability?
AForcing every workload to run on a single virtual machine
BAdding or removing capacity quickly to match demand changes
CPermanently locking in a fixed amount of compute regardless of demand
DEliminating all need for monitoring or operational oversight
Answer & Solution
Correct answer: B. Adding or removing capacity quickly to match demand changes
Scalability is the ability to grow (scale up / out) or shrink (scale down / in) capacity in response to demand. Monitoring is still required; fixed-capacity workloads and single-VM constraints are anti-patterns.
