Where should an Elastic Beanstalk configuration file named healthcheckur1.config be placed in the application source bundle?
A. In the root of the application
B. In the bin folder
C. In healthcheckur1.config.ebextension under root
D. In the .ebextensions folder
A Developer will be using the AWS CLI on a local development server to manage AWS services.
What can be done to ensure that the CLI uses the Developer's IAM permissions when making commands?
A. Specify the Developer's IAM access key ID and secret access key as parameters for each CLI command.
B. Run the aws configure CLI command, and provide the Developer's IAM access key ID and secret access key.
C. Specify the Developer's IAM user name and password as parameters for each CLI command.
D. Use the Developer's IAM role when making the CLI command.
A company is migrating from a monolithic architecture to a microservices-based architecture. The Developers need to refactor the application so that the many microservices can asynchronously communicate with each other without impacting performance.
Use of which managed AWS services will enable asynchronous message passing? (Choose two.)
A. Amazon SQS
B. Amazon Cognito
C. Amazon Kinesis
D. Amazon SNS
E. Amazon ElastiCache
A company uses Amazon DynamoDB for managing and tracking orders. The DynamoDB table is partitioned based on the order date. The company receives a huge increase in orders during a sales event, causing DynamoDB writes to throttle, and the consumed throughput is far below the provisioned throughput.
According to AWS best practices, how can this issue be resolved with MINIMAL costs?
A. Create a new DynamoDB table for every order date.
B. Increase the read and write capacity units of the DynamoDB table.
C. Add a random number suffix to the partition key values.
D. Add a global secondary index to the DynamoDB table.
An organization is using Amazon CloudFront to ensure that its users experience low-latency access to its web application. The organization has identified a need to encrypt all traffic between users and CloudFront, and all traffic between CloudFront and the web application.
How can these requirements be met? (Choose two.)
A. Use AWS KMS to encrypt traffic between CloudFront and the web application.
B. Set the Origin Protocol Policy to "HTTPS Only".
C. Set the Origin's HTTP Port to 443.
D. Set the Viewer Protocol Policy to "HTTPS Only" or "Redirect HTTP to HTTPS".
E. Enable the CloudFront option Restrict Viewer Access.
An application stores images in an S3 bucket. Amazon S3 event notifications are used to trigger a Lambda function that resizes the images. Processing each image takes less than a second. How will AWS Lambda handle the additional traffic?
A. Lambda will scale out to execute the requests concurrently.
B. Lambda will handle the requests sequentially in the order received.
C. Lambda will process multiple images in a single execution.
D. Lambda will add more compute to each execution to reduce processing time.
How is provisioned throughput affected by the chosen consistency model when reading data from a DynamoDB table?
A. Strongly consistent reads use the same amount of throughput as eventually consistent reads
B. Strongly consistent reads use more throughput than eventually consistent reads.
C. Strongly consistent reads use less throughput than eventually consistent reads
D. Strongly consistent reads use variable throughput depending on read activity
A Developer must encrypt a 100-GB object using AWS KMS. What is the BEST approach?
A. Make an Encrypt API call to encrypt the plaintext data as ciphertext using a customer master key (CMK)
B. Make an Encrypt API call to encrypt the plaintext data as ciphertext using a customer master key (CMK) with imported key material
C. Make a GenerateDataKey API call that returns a plaintext key and an encrypted copy of a data key. Use a plaintext key to encrypt the data
D. Make a GenerateDataKeyWithoutPlaintext API call that returns an encrypted copy of a data key. Use an encrypted key to encrypt the data
A serverless application uses an API Gateway and AWS Lambda.
Where should the Lambda function store its session information across function calls?
A. In an Amazon DynamoDB table
B. In an Amazon SQS queue
C. In the local filesystem
D. In an SQLite session table using -DSQLITE_ENABLE_SESSION
A Developer writes an AWS Lambda function and uploads the code in a .ZIP file to Amazon S3. The Developer makes changes to the code and uploads a new .ZIP file to Amazon S3. However, Lambda executes the earlier code. How can the Developer fix this in the LEAST disruptive way?
A. Create another Lambda function and specify the new .ZIP file.
B. Call the update-function-code API.
C. Remove the earlier .ZIP file first, then add the new .ZIP file.
D. Call the create-alias API.
