Question #1347
A media streaming company is migrating its on-premises infrastructure to AWS and needs to automatically manage traffic spikes during peak viewing hours in a cost-efficient manner. Which AWS Cloud features should the company use? (Choose two.)
Multi-AZ deployment
Pay-as-you-go pricing
AWS Identity and Access Management (IAM)
Auto Scaling groups
Amazon CloudWatch alarms
Explanation
The correct answers are B and D.
- B (Pay-as-you-go pricing) allows the company to pay only for the resources consumed during traffic spikes, avoiding upfront costs and over-provisioning. This aligns with cost efficiency.
- D (Auto Scaling groups) automatically adjusts compute resources (e.g., EC2 instances) based on demand, ensuring seamless handling of traffic spikes without manual intervention.
Other options are incorrect because:
- A (Multi-AZ deployment) focuses on high availability, not traffic scaling.
- C (IAM) manages access control, unrelated to scaling or cost optimization.
- E (CloudWatch alarms) monitors metrics and triggers actions (e.g., scaling) but does not directly manage traffic or reduce costs.
Key points: Auto Scaling handles dynamic workloads, while pay-as-you-go pricing ensures cost optimization for variable demand.
Answer
The correct answer is: BD
