NEW QUESTION # 458
A social media application stores millions of video clips in Amazon S3 and serves them to users across the world. The traffic to the application varies, but access often increases suddenly to more than 10,000 PUT requests and GET requests each second. As the application has grown in popularity, users report poor quality of video streaming. Which solution will provide the LARGEST improvement in performance?
Answer: C
Explanation:
The correct answer is D because Amazon CloudFront is the AWS content delivery network (CDN) designed to improve performance for users who access content globally. In this scenario, the application serves millions of video clips from Amazon S3 to users around the world, and the main problem is poor streaming quality as traffic scales. CloudFront addresses this by caching content at edge locations that are geographically closer to users, reducing latency and improving throughput.
AWS documentation emphasizes that CloudFront works especially well with Amazon S3 as an origin for static and streaming content. Instead of every viewer retrieving video data directly from the S3 bucket's Region, CloudFront serves cached objects from nearby edge locations. This provides a major performance boost for global audiences and helps absorb large traffic spikes more efficiently.
Option A is incorrect because Route 53 geolocation routing directs DNS queries based on location, but it does not cache or accelerate video delivery. Option B can improve regional redundancy, but simply replicating objects across Regions does not automatically provide fast global delivery or edge caching. Option C is about storage cost optimization, not delivery performance.
CloudFront is also well suited for sudden spikes in traffic because AWS's edge network is built for high-scale distribution. For video streaming workloads, the reduction in latency and the ability to serve content from nearby cached locations usually provide the largest performance improvement compared to the other options.
Therefore, the best solution is to create an Amazon CloudFront distribution with Amazon S3 as the origin
, making D the correct answer.
NEW QUESTION # 459
A company has a large amount of data in an Amazon DynamoDB table. A large batch of data is appended to the table once each day. The company wants a solution that will make all the existing and future data in DynamoDB available for analytics on a long-term basis.
Which solution meets these requirements with the LEAST operational overhead?
Answer: D
Explanation:
* Why Option A is Correct:DynamoDB supports incremental exports to Amazon S3 natively, making data analytics-ready with minimal operational overhead.
* Why Other Options are Incorrect:
* Option B: DynamoDB Streams require additional processing logic to write to S3, increasing complexity.
* Option C & D: Using EMR for data movement adds unnecessary operational overhead compared to native exports.
* AWS Documentation References:
* DynamoDB Exports to S3
NEW QUESTION # 460
A developer wants to reduce risk when deploying a new version of an existing AWS Lambda function. To test the Lambda function, the developer needs to split the traffic between the existing version and the new version of the Lambda function.
Which solution will meet these requirements?
Answer: D
NEW QUESTION # 461
A developer used the AWS SDK to create an application that aggregates and produces log records for 10 services. The application delivers data to an Amazon Kinesis Data Streams stream.
Each record contains a log message with a service name, creation timestamp, and other log information. The stream has 15 shards in provisioned capacity mode. The stream uses service name as the partition key.
The developer notices that when all the services are producing logs,
ProvisionedThroughputExceededException errors occur during PutRecord requests. The stream metrics show that the write capacity the applications use is below the provisioned capacity.
Answer: D
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
Issue Analysis:
The stream uses service name as the partition key. This can cause "hot partition" issues when a few service names generate significantly more logs compared to others, causing uneven distribution of data across shards.
Metrics show that the write capacity used is below provisioned capacity, which confirms that the throughput errors are due to shard-level limits and not overall capacity.
Option C: Change Partition Key to Creation Timestamp:
By changing the partition key to the creation timestamp (or a composite key including timestamp), the distribution of data across shards can be randomized, ensuring an even spread of records.
This resolves the shard overutilization issue and eliminates ProvisionedThroughputExceededException.
Why Other Options Are Incorrect:
Option A: Switching to on-demand capacity mode might temporarily alleviate the issue, but the root cause (hot partitioning) remains unresolved.
Option B: Adding shards increases capacity but does not fix the skewed data distribution caused by using the service name as the partition key.
Option D: Creating separate streams for each service adds unnecessary complexity and does not scale well as the number of services grows.

NEW QUESTION # 462
A developer is testing a Python application that is deployed on AWS Elastic Beanstalk. The application is using the Boto3 library to send events to an Amazon SQS queue. An external tool consumes the events.
During the tests, a ThrottlingException error occurs at irregular intervals.
What should the developer do to resolve this error?
Answer: C
Explanation:
Boto3 adaptive retry mode is designed to handle throttling by automatically retrying failed AWS API calls with dynamic backoff. This reduces request pressure during throttling events and allows the application to recover from irregular ThrottlingException errors without changing the Elastic Beanstalk environment.
