A developer is creating an application that includes an Amazon API Gateway REST API in the us-east-2 Region. The developer wants to use Amazon CloudFront and a custom domain name for the API. The developer has acquired an SSL/TLS certificate for the domain from a third-party provider.
How should the developer configure the custom domain for the application?
A company is planning to deploy an application on AWS behind an Elastic Load Balancing (ELB) load balancer. The application uses an HTTP/HTTPS listener and must access the client IP addresses.
Which load-balancing solution meets these requirements?
A developer needs to use a code template to create an automated deployment of an application onto Amazon EC2 instances. The template must be configured to repeat deployment, installation, and updates of resources for the application. The template must be able to create identical environments and roll back to previous versions.
Which solution will meet these requirements?
When using the AWS Encryption SDK how does the developer keep track of the data encryption keys used to encrypt data?
An application interacts with Amazon Aurora to store and track customer information. The primary database is set up with multiple read replicas for improving the performance of the read queries. However, one of the Aurora replicas is receiving most or all of the traffic, while the other Aurora replica remains idle.
How can this issue be resolved?
A developer is creating an AWS Lambda function that searches for Items from an Amazon DynamoDQ table that contains customer contact information. The DynamoDB table items have the customers as the partition and additional properties such as customer -type, name, and job_title.
The Lambda function runs whenever a user types a new character into the customer_type text Input. The developer wants to search to return partial matches of all tne email_address property of a particular customer type. The developer does not want to recreate the DynamoDB table.
What should the developer do to meet these requirements?
A company's developer has deployed an application in AWS by using AWS CloudFormation The CloudFormation stack includes parameters in AWS Systems Manager Parameter Store that the application uses as configuration settings. The application can modify the parameter values
When the developer updated the stack to create additional resources with tags, the developer noted that the parameter values were reset and that the values ignored the latest changes made by the application. The developer needs to change the way the company deploys the CloudFormation stack. The developer also needs to avoid resetting the parameter values outside the stack.
Which solution will meet these requirements with the LEAST development effort?
A company uses a custom root certificate authority certificate chain (Root CA Cert) that is 10 KB in size generate SSL certificates for its on-premises HTTPS endpoints. One of the company’s cloud based applications has hundreds of AWS Lambda functions that pull date from these endpoints. A developer updated the trust store of the Lambda execution environment to use the Root CA Cert when the Lambda execution environment is initialized. The developer bundled the Root CA Cert as a text file in the Lambdas deployment bundle.
After 3 months of development the root CA Cert is no longer valid and must be updated. The developer needs a more efficient solution to update the Root CA Cert for all deployed Lambda functions. The solution must not include rebuilding or updating all Lambda functions that use the Root CA Cert. The solution must also work for all development, testing and production environment. Each environment is managed in a separate AWS account.
When combination of steps Would the developer take to meet these environments MOST cost-effectively? (Select TWO)
Users are reporting errors in an application. The application consists of several micro services that are deployed on Amazon Elastic Container Serves (Amazon ECS) with AWS Fargate.
When combination of steps should a developer take to fix the errors? (Select TWO)
A developer is migrating a containerized application from an on-premises environment to the AWS Cloud. The developer is using the AWS CDK to provision a container in Amazon ECS on AWS Fargate. The container is behind an Application Load Balancer (ALB).
When the developer deploys the stack, the deployment fails because the ALB fails health checks. The developer needs to resolve the failed health checks.
Which solutions will meet this requirement? (Select TWO.)
A developer warns to add request validation to a production environment Amazon API Gateway API. The developer needs to test the changes before the API is deployed to the production environment. For the lest the developer will send test requests to the API through a testing tool.
Which solution will meet these requirements with the LEAST operational overhead?
A developer is trying get data from an Amazon DynamoDB table called demoman-table. The developer configured the AWS CLI to use a specific IAM use's credentials and ran the following command.
The command returned errors and no rows were returned.
What is the MOST likely cause of these issues?
A company deploys a new application to AWS. The company is streaming application logs to Amazon CloudWatch Logs. The company's development team must receive notification by email when the word "ERROR" appears in any log lines. A developer sets up an Amazon SNS topic and subscribes the development team to the topic.
What should the developer do next to meet the requirements?
A developer wants to store information about movies. Each movie has a title, release year, and genre. The movie information also can include additional properties about the cast and production crew. This additional information is inconsistent across movies. For example, one movie might have an assistant director, and another movie might have an animal trainer.
The developer needs to implement a solution to support the following use cases:
For a given title and release year, get all details about the movie that has that title and release year.
For a given title, get all details about all movies that have that title.
For a given genre, get all details about all movies in that genre.
Which data store configuration will meet these requirements?
A company is implementing an application on Amazon EC2 instances. The application needs to process incoming transactions. When the application detects a transaction that is not valid, the application must send a chat message to the company's support team. To send the message, the application needs to retrieve the access token to authenticate by using the chat API.
A developer needs to implement a solution to store the access token. The access token must be encrypted at rest and in transit. The access token must also be accessible from other AWS accounts.
Which solution will meet these requirements with the LEAST management overhead?
