CLF-C02 Question 10
Select 2A company is migrating its on-premises web application to AWS. The application experiences unpredictable traffic spikes during marketing campaigns, and it is critical that the application stays available to users during these spikes. Which combination of AWS benefits addresses these requirements?
- A
High availability ensures the application remains operational during unexpected traffic spikes.
- B
Elasticity allows the application to automatically scale resources up or down based on demand.
- C
Agility ensures the application can recover from hardware failures automatically.
- D
AWS provides unlimited storage for logs and backups, ensuring compliance during traffic spikes.
- E
Cost optimization ensures the application runs with minimal expenses during high traffic.
Show answer and explanation
Correct answers: A, B
Explanation
To meet the company's requirements of handling unpredictable traffic spikes and ensuring the application remains operational, leveraging AWS's high availability and elasticity features is essential. High availability ensures the application is always accessible, while elasticity allows resources to scale dynamically based on demand, preventing performance degradation or downtime.
- A. Correct.
High availability ensures minimal downtime and consistent performance by distributing workloads and utilizing fault-tolerant architecture, which is critical during traffic spikes.
- B. Correct.
Elasticity enables the automatic scaling of resources, ensuring the application can handle increases in demand without manual intervention.
- C. Incorrect.
Agility refers to the speed and ease of deploying and adapting applications, but it does not directly address hardware failure recovery or traffic spike handling.
- D. Incorrect.
While AWS provides scalable storage, this option does not address the need for operational availability or resource scaling during traffic spikes.
- E. Incorrect.
Cost optimization is an AWS benefit but is unrelated to ensuring high availability or handling traffic spikes.
