A Development team currently supports an application that uses an in-memory store to save accumulated game results. Individual results are stored in a database. As part of migrating to AWS, the team needs to use automatic scaling. The team knows this will yield inconsistent results.
Where should the team store these accumulated game results to BEST allow for consistent results without impacting performance?
A. Amazon S3
B. Amazon RDS
C. Amazon ElastiCache
D. Amazon Kinesis
An application that runs on an Amazon EC2 instance needs to access and make API calls to multiple AWS services. What is the MOST secure way to provide access to the AWS services with MINIMAL management overhead?
A. Use AWS KMS to store and retrieve credentials.
B. Use EC2 instance profiles.
C. Use AWS root user to make requests to the application.
D. Store and retrieve credentials from AWS CodeCommit.
A Developer is creating a Lambda function that will generate and export a file. The function requires 100 MB of temporary storage for temporary files while executing. These files will not be needed after the function is complete. How can the Developer MOST efficiently handle the temporary files?
A. Store the files in EBS and delete the files at the end of the Lambda function.
B. Copy the files to EFS and delete the files at the end of the Lambda function.
C. Store the files in the /tmp directory and delete the files at the end of the Lambda function.
D. Copy the files to an S3 bucket with a lifecycle policy to delete the files.
A developer is setting up Amazon API gateway for their company's products. The API will be registered developers to query and update their environments. The company wants to limit the amount of requests end users send for.bot cost and security reason management wants to offer registered the option of buying larger packages that allow for more requests.
A. Enable throttling for the API Gateway stage Set a value tor both the rate and burst capacity If a registered larger package, create a stage for them, adjust the values, and share the new URL with them.
B. Set up Amazon CloudWatch API logging in API Gateway Create a filter based on the user and requestTime fields and create an alarm on this filter Write an AWS Lambda function to analyze the values and requester information, and respond accordingly Set up the function as the target tor the alarm If a registered user chooses a larger package, update the Lambda code with the values
C. Enable Amazon CloudWatch metrics for the API Gateway stage Set up CloudWatch alarms based oft the Count metric and the ApiName, Method, Resource, and Stage dimensions to alerts when request rates pass the threshold Set the alarm action to Deny If a registered user chooses a larger package, create a user-specific alarm and adjust the values
D. Set up a default usage plan specify values for the rate and burst capacity, and associate it with a stage If a registered user chooses a larger package, create a custom plan with the appropriate values and associate the plan with the user
A Development team is working on a case management solution that allows medical claims to be processed and reviewed. Users log in to provide information related to their medical and financial situations.
As part of the application, sensitive documents such as medical records, medical imaging, bank statements, and receipts are uploaded to Amazon S3. All documents must be securely transmitted and stored. All access to the documents must
be recorded for auditing.
What is the MOST secure approach?
A. Use S3 default encryption using Advanced Encryption Standard-256 (AES-256) on the destination bucket.
B. Use Amazon Cognito for authorization and authentication to ensure the security of the application and documents.
C. Use AWS Lambda to encrypt and decrypt objects as they are placed into the S3 bucket.
D. Use client-side encryption/decryption with Amazon S3 and AWS KMS.
A Developer wants access to make the log data of an application running on an EC2 instance available to systems administrators. Which of the following enables monitoring of this metric in Amazon CloudWatch?
A. Retrieve the log data from CloudWatch using the GetMetricData API call
B. Retrieve the log data from AWS CloudTrail using the LookupEvents API call.
C. Launch a new EC2 instance, configure Amazon CloudWatch Events, and then install the application.
D. Install the Amazon CloudWatch Logs agent on the EC2 instance that the application is running on.
Company D is running their corporate website on Amazon S3 accessed from http//www.companyd.com. Their marketing team has published new web fonts to a separate S3 bucket accessed by the S3 endpoint https://s3-us-west1.amazonaws.com/cdfonts. While testing the new web fonts, Company D recognized the web fonts are being blocked by the browser.
What should Company D do to prevent the web fonts from being blocked by the browser?
A. Enable versioning on the cdfonts bucket for each web font
B. Create a policy on the cdfonts bucket to enable access to everyone
C. Add the Content-MD5 header to the request for webfonts in the cdfonts bucket from the website
D. Configure the cdfonts bucket to allow cross-origin requests by creating a CORS configuration
How can software determine the public and private IP addresses of the Amazon EC2 instance that it is running on?
A. Query the appropriate Amazon CloudWatch metric.
B. Use ipconfig or ifconfig command.
C. Query the local instance userdata.
D. Query the local instance metadata.
An application writes items to an Amazon DynamoDB table. As the application scales to thousands of instances, calls to the DynamoDB API generate occasional ThrottlingException errors. The application is coded in a language incompatible with the AWS SDK.
How should the error be handled?
A. Add exponential backoff to the application logic
B. Use Amazon SQS as an API message bus
C. Pass API calls through Amazon API Gateway
D. Send the items to DynamoDB through Amazon Kinesis Data Firehose
A company is using continuous integration and continuous delivery systems. A Developer now needs to automate a software package deployment to both Amazon EC2 instances and virtual servers running on-premises. Which AWS service should be used to accomplish this?
A. AWS CodePipeline
B. AWS CodeBuild
C. AWS Elastic Beanstalk
D. AWS CodeDeploy
