ANS-C01 Question 401
Select 3Your organization is live-streaming a company-wide event to thousands of employees spread across multiple locations. The event needs to be accessible in real-time with minimal latency while reducing overall bandwidth consumption. Which methods can be used to achieve this goal?
- A
Use Amazon CloudFront to distribute the live stream to employees globally via edge locations.
- B
Implement a multicast network strategy to deliver the stream within the organization's on-premises network.
- C
Deploy multiple unicast streams from the source to each employee's device to ensure reliable delivery.
- D
Leverage AWS Elemental MediaLive to encode the stream and use AWS Elemental MediaPackage for optimized delivery.
Show answer and explanation
Correct answers: A, B, D
Explanation
To reduce bandwidth consumption for a live-streaming event, combining AWS services like CloudFront for global delivery, multicast for on-premises efficiency, and MediaLive/MediaPackage for optimized encoding and delivery provides an effective solution. These approaches minimize network strain while ensuring a smooth viewing experience. Unicast, on the other hand, increases bandwidth usage and is not suitable for the specified scenario.
- A. Correct.
Amazon CloudFront is a content delivery network capable of caching and delivering content to edge locations, significantly reducing bandwidth usage and improving performance for global audiences.
- B. Correct.
Multicast is an efficient way to deliver the same data to multiple recipients within an on-premises network, reducing bandwidth usage as compared to multiple unicast streams.
- C. Incorrect.
Unicast streams send individual streams to every recipient, which increases bandwidth usage and does not align with the goal of reducing bandwidth consumption.
- D. Correct.
AWS Elemental MediaLive and MediaPackage are AWS services that can encode and optimize video streams for efficient delivery, further reducing bandwidth consumption and ensuring high-quality real-time streaming.
