Question 88 (Topic 1)

A company’s application is receiving data from multiple data sources. The size of the data varies and is expected to increase over time. The current maximum size is 700 KB. The data volume and data size continue to grow as more data sources are added. The company decides to use Amazon DynamoDB as the primary database for the application. A solutions architect needs to identify a solution that handles the large data sizes. Which solution will meet these requirements in the MOST operationally efficient way?

Select an option, then click Submit answer.

○ Create an AWS Lambda function to filter the data that exceeds DynamoDB item size limits. Store the larger data in an Amazon DocumentDB (with MongoDB compatibility) database.
○ Store the large data as objects in an Amazon S3 bucket. In a DynamoDB table, create an item that has an attribute that points to the S3 URL of the data.
○ Split all incoming large data into a collection of items that have the same partition key. Write the data to a DynamoDB table in a single operation by using the BatchWriteItem API operation.
○ Create an AWS Lambda function that uses gzip compression to compress the large objects as they are written to a DynamoDB table.

Reference / correct answer:

Store the large data as objects in an Amazon S3 bucket. In a DynamoDB table, create an item that has an attribute that points to the S3 URL of the data.

Most accepted answer: B. Store the large data as objects in an Amazon S3 bucket. In a DynamoDB table, create an item that has an attribute that points to the S3 URL of the data.

Selected Answer: B option B is the most operationally efficient solution for handling large data sizes in Amazon DynamoDB. upvoted 9 times

Selected Answer: B B is correct upvoted 5 times

Selected Answer: B A - Introducing another database. No need. B - Decoupling the large data storage (S3) from the metadata or smaller structured data (DynamoDB) is an AWS-recommended pattern. C - OK but this is too complicated. D - Compression does not guarantee that the data will always fit within DynamoDB's 400 KB limit. upvoted 2 times

Selected Answer: B AnswerB Compresion of data in DynamoDB is a good idea especially for text data link from forum, but to do that we do not need AWS Lambda if I'm not wrong. In other head Storing big object on S3 and seving URL to it in DynamoDB is one of best practices mentioned by Amazon. Hence we do not know what kind of data we are storing in DB and how big objects will be in the future option B looks like the best solution. https://aws.amazon.com/blogs/database/large-object-storage-strategies-for-amazon-dynamodb/ <<<< Read Option 2 https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-use-s3-too.html upvoted 1 times

Question 89 (Topic 1)

A company is running a highly sensitive application on Amazon EC2 backed by an Amazon RDS database. Compliance regulations mandate that all personally identifiable information (PII) be encrypted at rest. Which solution should a solutions architect recommend to meet this requirement with the LEAST amount of changes to the infrastructure?

Select an option, then click Submit answer.

○ Deploy AWS Certificate Manager to generate certificates. Use the certificates to encrypt the database volume.
○ Deploy AWS CloudHSM, generate encryption keys, and use the keys to encrypt database volumes.
○ Configure SSL encryption using AWS Key Management Service (AWS KMS) keys to encrypt database volumes.
○ Configure Amazon Elastic Block Store (Amazon EBS) encryption and Amazon RDS encryption with AWS Key Management Service (AWS KMS) keys to encrypt instance and database volumes.

Reference / correct answer:

Configure Amazon Elastic Block Store (Amazon EBS) encryption and Amazon RDS encryption with AWS Key Management Service (AWS KMS) keys to encrypt instance and database volumes.

Most accepted answer: D. Configure Amazon Elastic Block Store (Amazon EBS) encryption and Amazon RDS encryption with AWS Key Management Service (AWS KMS) keys to encrypt instance and database volumes.

Community votes: D=3

Selected Answer: D Amazon RDS relies on Amazon EBS volumes for storage. By configuring Amazon EBS encryption, the underlying storage volumes are encrypted. upvoted 7 times

Selected Answer: D - Option D requires the least infrastructure modification as it leverages existing features of EBS and RDS to enable encryption with KMS keys. - This is the most straightforward way to meet the compliance requirement without significant changes to the existing setup. upvoted 1 times

SSL/Certificate => encrypt in transit, so A and C are wrong. so i feel the answer is between B and D. upvoted 2 times

Selected Answer: D Encryption should be KMS, SSL is for transit not at rest... Even though the question never mentioned any EBS volumes whatsoever, I would still go for D.... upvoted 4 times

answer:C upvoted 2 times

Question 90 (Topic 1)

A news company that has reporters all over the world is hosting its broadcast system on AWS. The reporters send live broadcasts to the broadcast system. The reporters use software on their phones to send live streams through the Real Time Messaging Protocol (RTMP). A solutions architect must design a solution that gives the reporters the ability to send the highest quality streams. The solution must provide accelerated TCP connections back to the broadcast system. What should the solutions architect use to meet these requirements?

○ Amazon CloudFront
○ AWS Global Accelerator
○ AWS Client VPN
○ Amazon EC2 instances and AWS Elastic IP addresses
