• Question 662:

  A company's main intranet page has experienced degraded response times as its user base has increased although there are no reports of users seeing error pages. The application uses Amazon DynamoDB in read-only mode.

  Amazon DynamoDB latency metrics for successful requests have been in a steady state even during times when users have reported degradation. The Development team has correlated the issue to ProvisionedThrough put Exceeded exceptions in the application logs when doing Scan and read operations The team also identified an access pattern of steady spikes of read activity on a distributed set of individual data items.

  The Chief Technology Officer wants to improve the user experience.

  Which solutions will meet these requirements with the LEAST amount of changes to the application? (Choose two.)

  A. Change the data model of the DynamoDB tables to ensure that all Scan and read operations meet DynamoDB best practices of uniform data access, reaching the full request throughput provisioned for the DynamoDB tables.
  B. Enable DynamoDB Auto Scaling to manage the throughput capacity as table traffic increases. Set the upper and lower limits to control costs and set a target utilization given the peak usage and how quickly the traffic changes.
  C. Provision Amazon ElastiCache for Redis with cluster mode enabled. The cluster should be provisioned with enough shards to spread the application load and provision at least one read replica node for each shard.
  D. Implement the DynamoDB Accelerator (DAX) client and provision a DAX cluster with the appropriate node types to sustain the application load. Tune the item and query cache configuration for an optimal user experience.
  E. Remove error retries and exponential backoffs in the application code to handle throttling errors.

• Question 668:

  A software as a service (SaaS) company offers a cloud solution for document management to private law firms and the public sector. A local government client recently mandated that highly confidential documents cannot be stored outside the country. The company CIO asks a Solutions Architect to ensure the application can adapt to this new requirement. The CIO also wants to have a proper backup plan for these documents, as backups are not currently performed.

  What solution meets these requirements?

  A. Tag documents that are not highly confidential as regular in Amazon S3. Create individual S3 buckets for each user. Upload objects to each user's bucket. Set S3 bucket replication from these buckets to a central S3 bucket in a different AWS account and AWS Region. Configure an AWS Lambda function triggered by scheduled events in Amazon CloudWatch to delete objects that are tagged as secret in the S3 backup bucket.
  B. Tag documents as either regular or secret in Amazon S3. Create an individual S3 backup bucket in the same AWS account and AWS Region. Create a cross-region S3 bucket in a separate AWS account. Set proper IAM roles to allow cross-region permissions to the S3 buckets. Configure an AWS Lambda function triggered by Amazon CloudWatch scheduled events to copy objects that are tagged as secret to the S3 backup bucket and objects tagged as normal to the cross-region S3 bucket.
  C. Tag documents as either regular or secret in Amazon S3. Create an individual S3 backup bucket in the same AWS account and AWS Region. Use S3 selective cross-region replication based on object tags to move regular documents to an S3 bucket in a different AWS Region. Configure an AWS Lambda function that triggers when new S3 objects are created in the main bucket to replicate only documents tagged as secret into the S3 bucket in the same AWS Region.
  D. Tag highly confidential documents as secret in Amazon S3. Create an individual S3 backup bucket in the same AWS account and AWS Region. Use S3 selective cross-region replication based on object tags to move regular documents to a different AWS Region. Create an Amazon CloudWatch Events rule for new S3 objects tagged as secret to trigger an AWS Lambda function to replicate them into a separate bucket in the same AWS Region.
  D. Tag highly confidential documents as secret in Amazon S3. Create an individual S3 backup bucket in the same AWS account and AWS Region. Use S3 selective cross-region replication based on object tags to move regular documents to a different AWS Region. Create an Amazon CloudWatch Events rule for new S3 objects tagged as secret to trigger an AWS Lambda function to replicate them into a separate bucket in the same AWS Region.

• Question 669:

  A company is having issues with a newly deployed serverless infrastructure that uses Amazon API Gateway, Amazon Lambda, and Amazon DynamoDB.

  In a steady state, the application performs as expected. However, during peak load, tens of thousands of simultaneous invocations are needed and user requests fail multiple times before succeeding. The company has checked the logs for

  each component, focusing specifically on Amazon CloudWatch Logs for Lambda. There are no errors logged by the services or applications.

  What might cause this problem?

  A. Lambda has very low memory assigned, which causes the function to fail at peak load.
  B. Lambda is in a subnet that uses a NAT gateway to reach out of the internet, and the function instance does not have sufficient Amazon EC2 resources in the VPC to scale with the load.
  C. The throttle limit set on API Gateway is very low. During peak load, the additional requests are not making their way through to Lambda.
  D. DynamoDB is set up in an auto scaling mode. During peak load, DynamoDB adjusts capacity and throughput behind the scenes, which is causing the temporary downtime. Once the scaling completes, the retries go through successfully.
  C. The throttle limit set on API Gateway is very low. During peak load, the additional requests are not making their way through to Lambda.

• Question 670:

  A company currently has data hosted in an IBM Db2 database. A web application calls an API that runs stored procedures on the database to retrieve user information data that is read-only. This data is historical in nature and changes on a daily basis. When a user logs in to the application, this data needs to be retrieved within 3 seconds. Each time a user logs in, the stored procedures run. Users log in several times a day to check stock prices.

  Running this database has become cost-prohibitive due to Db2 CPU licensing. Performance goals are not being met. Timeouts from Db2 are common due to long-running queries.

  Which approach should a solutions architect take to migrate this solution to AWS?

  A. Rehost the Db2 database in Amazon Fargate. Migrate all the data. Enable caching in Fargate. Refactor the API to use the Fargate Db2 database. Implement Amazon API Gateway and enable API caching.
  B. Use AWS DMS to migrate data to Amazon DynamoDB using a continuous replication task. Refactor the API to use the DynamoDB data. Implement the refactored API in Amazon API Gateway and enable API caching.
  C. Create a local cache on the mainframe to store query outputs. Use SFTP to sync to Amazon S3 on a daily basis. Refactor the API to use Amazon EFS. Implement Amazon API Gateway and enable API caching.
  D. Extract data daily and copy the data to AWS Snowball for storage on Amazon S3. Sync daily. Refactor the API to use the S3 data. Implement Amazon API Gateway and enable API caching.
  A. Rehost the Db2 database in Amazon Fargate. Migrate all the data. Enable caching in Fargate. Refactor the API to use the Fargate Db2 database. Implement Amazon API Gateway and enable API caching.
