A developer is developing a serverless application using AWS Lambda and is required to establish a REST API that utilizes the HTTP GET technique. What has to be specified to satisfy this criterion? (Select two.)
A. A Lambda@Edge function
B. An Amazon API Gateway with a Lambda function
C. An exposed GET method in an Amazon API Gateway
D. An exposed GET method in the Lambda function
E. An exposed GET method in Amazon Route 53
On AWS Lambda, a developer is developing an image microservice. The service relies on a number of libraries that are not included in the Lambda runtime environment. Which approach should the developer choose while developing the Lambda deployment package?
A. Create a ZIP file with the source code and all dependent libraries.
B. Create a ZIP file with the source code and a script that installs the dependent libraries at runtime
C. Create a ZIP file with the source code. Stage the dependent libraries on an Amazon S3 bucket indicated by the Lambda environment variable LD_LIBRARY_PATH
D. Create a ZIP file with the source code and a buildspec.yaml file that installs the dependent libraries on AWS Lambda.
A business want to containerize and deploy an existing three-tier web application on Amazon ECS Fargate. Session data is used by the program to keep track of user activity. Which strategy would result in the BEST customer experience?
A. Provision a Redis cluster in Amazon ElastiCache and save the session data in the cluster.
B. Create a session table in Amazon Redshift and save the session data in the database table.
C. Enable session stickiness in the existing Network Load Balancer and manage the session data in the container.
D. Use an Amazon S3 bucket as data store and save the session data in the bucket.
An Amazon EC2 application establishes connections to an Amazon RDS SQL Server database. The developer does not want to keep the database's user name and password in the code. Additionally, the developer would want to have the credentials rotated automatically. What is the SAFEST method for storing and accessing database credentials?
A. Create an IAM role that has permissions to access the database. Attach the role to the EC2 instance.
B. Use AWS Secrets Manager to store the credentials. Retrieve the credentials from Secrets Manager as needed.
C. Store the credentials in an encrypted text file in an Amazon S3 bucket. Configure the EC2 instance's user data to download the credentials from Amazon S3 as the instance boots.
D. Store the user name and password credentials directly in the source code. No further action is needed because the source code is stored in a private repository.
Which of the following are effective use cases for Amazon ElastiCache? (Select two.)
A. Improve the performance of S3 PUT operations.
B. Improve the latency of deployments performed by AWS CodeDeploy.
C. Improve latency and throughput for read-heavy application workloads.
D. Reduce the time required to merge AWS CodeCommit branches.
E. Improve performance of compute-intensive applications.
A developer is developing a web application that requires authentication but also requires guest access in order to allow restricted access to users who do not want to login. Which service can assist the application in allowing guest access?
A. IAM temporary credentials using AWS STS.
B. Amazon Directory Service
C. Amazon Cognito with unauthenticated access enabled
D. IAM with SAML integration
A web application is developed to enable new users to register using their email addresses. The program will store user characteristics and anticipates millions of users signing up. What should the developer do to accomplish the design objectives?
A. Amazon Cognito user pools
B. AWS Mobile Hub user data storage
C. Amazon Cognito Sync
D. AWS Mobile Hub cloud logic
A development team is constructing a new application that will operate on Amazon EC2 and make use of Amazon DynamoDB for storage. All developers have IAM user accounts allocated to the same IAM group. Currently, developers may create EC2 instances, but they must also be allowed to launch EC2 instances with an instance role that grants access to Amazon DynamoDB. Which AWS IAM modifications are required to enable this feature when establishing an instance role?
A. Create an IAM permission policy attached to the role that allows access to DynamoDB. Add a trust policy to the role that allows DynamoDB to assume the role. Attach a permissions policy to the development group in AWS IAM that allows developers to use the iam:GetRole and iam:PassRole permissions for the role.
B. Create an IAM permissions policy attached to the role that allows access to DynamoDB. Add a trust policy to the role that allows Amazon EC2 to assume the role. Attach a permissions policy to the development group in AWS IAM that allows developers to use the iam:PassRole permission for the role.
C. Create an IAM permission policy attached to the role that allows access to Amazon EC2. Add a trust policy to the role that allows DynamoDB to assume the role. Attach a permissions policy to the development group in AWS IAM that allows developers to use the iam:PassRole permission for the role.
D. Create an IAM permissions policy attached to the role that allows access to DynamoDB. Add a trust policy to the role that allows Amazon EC2 to assume the role. Attach a permissions policy to the development group in AWS IAM that allows developers to use the iam:GetRole permission for the role.
A business is transferring its on-premises MySQL database to Amazon RDS for MySQL. The firm has read-intensive workloads and wants to ensure that its code is refactored to obtain the best possible read performance for its queries. How is this aim to be accomplished?
A. Add database retries to effectively use RDS with vertical scaling
B. Use RDS with multi-AZ deployment
C. Add a connection string to use an RDS read replica for read queries
D. Add a connection string to use a read replica on an EC2 instance.
Each day, a business runs an application that is responsible for processing several thousand external callbacks. The company's system administrators want to know the total number of calls received on a rolling basis, and they want this data to be accessible for a period of ten days. Additionally, the organization want to be able to send automatic notifications when the number of callbacks surpasses predefined criteria. What is the MOST cost-effective method for tracking and alerting on these statistics?
A. Push callback data to an Amazon RDS database that can be queried to show historical data and to alert on exceeded thresholds.
B. Push callback data to AWS X-Ray and use AWS Lambda to query, display, and alert on exceeded thresholds.
C. Push callback data to Amazon Kinesis Data Streams and invoke an AWS Lambda function that stores data in Amazon DynamoDB and sends the required alerts.
D. Push callback data to Amazon CloudWatch as a custom metric and use the CloudWatch alerting mechanisms to alert System Administrators.
