A solutions architect must prevent large instances from being launched in all accounts. How can the solutions architect meet this requirement with the LEAST operational overhead?
A company is implementing a new application on AWS. The company will run the application on multiple Amazon EC2 instances across multiple Availability Zones within multiple AWS Regions. The application will be available through the internet. Users will access the application from around the world. The company wants to ensure that each user who accesses the application is sent to the EC2 instances that are closest to the user's location. Which solution will meet these requirements?
A company stores customer data in a multitenant Amazon S3 bucket. Each customer's data is stored in a prefix that is unique to the customer. The company needs to migrate data for specific customers to a new. dedicated S3 bucket that is in the same AWS Region as the source bucket. The company must preserve object metadata such as creation date and version IDs. After the migration is finished, the company must delete the source data for the migrated customers from the original multitenant S3 bucket. Which combination of solutions will meet these requirements with the LEAST overhead? (Select THREE.)

An online education platform experiences lag and buffering during peak usage hours, when thousands of students access video lessons concurrently. A solutions architect needs to improve the performance of the education platform.

The platform needs to handle unpredictable traffic surges without losing responsiveness. The platform must provide smooth video playback performance at all times. The platform must create multiple copies of each video lesson and store the copies in various bitrates to serve users who have different internet speeds. The smallest video size is 7 GB.

Which solution will meet these requirements MOST cost-effectively?

A.

Use Amazon ElastiCache to cache videos in all the required bitrates. Use AWS Lambda functions to process the videos and to convert the videos to the required bitrates.

Answers
A.

Use Amazon ElastiCache to cache videos in all the required bitrates. Use AWS Lambda functions to process the videos and to convert the videos to the required bitrates.

B.

Create an Auto Scaling group that includes Amazon EC2 instances that are sized to meet peak loads. Use the Auto Scaling group to serve videos. Use the Auto Scaling group to convert the videos to the required bitrates.

Answers
B.

Create an Auto Scaling group that includes Amazon EC2 instances that are sized to meet peak loads. Use the Auto Scaling group to serve videos. Use the Auto Scaling group to convert the videos to the required bitrates.

C.

Store a copy of every video in every required bitrate in an Amazon S3 bucket. Use a single Amazon EC2 instance to serve the videos.

Answers
C.

Store a copy of every video in every required bitrate in an Amazon S3 bucket. Use a single Amazon EC2 instance to serve the videos.

D.

Use Amazon Kinesis Video Streams to store and serve the videos. Use AWS Lambda functions to process the videos and to convert the videos to the required bitrates.

Answers
D.

Use Amazon Kinesis Video Streams to store and serve the videos. Use AWS Lambda functions to process the videos and to convert the videos to the required bitrates.

Suggested answer: C

Explanation:

The most cost-effective solution for serving video content with different bitrates is to store multiple versions of each video in Amazon S3. S3 provides scalable and cost-effective storage for large media files. Serving the videos from a single Amazon EC2 instance ensures low-latency delivery, and S3 storage helps minimize costs.

Option A (ElastiCache): Caching large video files in memory would be prohibitively expensive and unnecessary.

Option B (Auto Scaling group): Using Auto Scaling groups to serve video is less cost-effective compared to leveraging S3 for static storage.

Option D (Kinesis Video Streams): Kinesis Video Streams is designed for real-time video streaming and is not suitable for storing and serving pre-recorded videos.
