Question 623
A media company serves static images to viewers in many countries and wants them delivered near viewers. Which AWS service or cloud concept is the MOST direct match for this need?
- Managed service operations
- Resource pooling
- Edge content delivery
- Fault tolerance
Explanation
Correct Answer
C:Edge content delivery fits the need because an edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users. The relevant capability or responsibility is: Cache frequently requested content at locations closer to end users.
Incorrect Answers
A:Managed service operations is associated with a different use case: an analytics team prefers a managed database rather than operating its own database host. Managed AWS offerings take on selected provisioning and maintenance tasks while customers remain responsible for their data and access policies. The question instead focuses on a media company serves static images to viewers in many countries and wants them delivered near viewers; Edge content delivery is the more direct match.
B:Resource pooling is associated with a different use case: several departments need separate virtual workloads without each purchasing dedicated physical machines. Cloud resource pooling supports multiple customers and workloads through provider-managed shared infrastructure with isolation controls. The question instead focuses on a media company serves static images to viewers in many countries and wants them delivered near viewers; Edge content delivery is the more direct match.
D:Fault tolerance is associated with a different use case: a payment-processing workload must continue processing transactions when an individual component unexpectedly fails. Fault tolerance keeps service functioning when failures happen, often through replicated or redundant components. The question instead focuses on a media company serves static images to viewers in many countries and wants them delivered near viewers; Edge content delivery is the more direct match.
Question 624
A project manager compares Agility with other AWS concepts while considering this need: a startup needs to launch a pilot environment within hours rather than wait for a server purchase. Which pairing assigns the responsibilities or benefits correctly?
