Amazon AWS Certified Solutions Architect - Professional (SAP-C02) Sample Questions (Q648-Q653):

NEW QUESTION # 648
A company runs an unauthenticated static website (www.example.com) that includes a registration form for users. The website uses Amazon S3 for hosting and uses Amazon CloudFront as the content delivery network with AWS WAF configured. When the registration form is submitted, the website calls an Amazon API Gateway API endpoint that invokes an AWS Lambda function to process the payload and forward the payload to an external API call.
During testing, a solutions architect encounters a cross-origin resource sharing (CORS) error. The solutions architect confirms that the CloudFront distribution origin has the Access-Control-Allow-Origin header set to www.example.com.
What should the solutions architect do to resolve the error?

A. Enable the CORS setting on the Lambda function. Ensure that the return code of the function has the Access-Control-Allow-Origin header set to www.example.com.
B. Enable the CORS setting in AWS WAF. Create a web ACL rule in which the Access-Control-Allow-Origin header is set to www.example.com.
C. Enable the CORS setting on the API Gateway API endpoint. Ensure that the API endpoint is configured to return all responses that have the Access-Control -Allow-Origin header set to www.example.com.
D. Change the CORS configuration on the S3 bucket. Add rules for CORS to the Allowed Origin element for www.example.com.

Answer: C

Explanation:
CORS errors occur when a web page hosted on one domain tries to make a request to a server hosted on another domain. In this scenario, the registration form hosted on the static website is trying to make a request to the API Gateway API endpoint hosted on a different domain, which is causing the error. To resolve this error, the Access-Control-Allow-Origin header needs to be set to the domain from which the request is being made. In this case, the header is already set to www.example.com on the CloudFront distribution origin.
Therefore, the solutions architect should enable the CORS setting on the API Gateway API endpoint and ensure that the API endpoint is configured to return all responses that have the Access-Control-Allow-Origin header set to www.example.com. This will allow the API endpoint to respond to requests from the static website without a CORS error.

NEW QUESTION # 649
A company is using AWS CodePipeline for the CI/CD of an application to an Amazon EC2 Auto Scaling group. All AWS resources are defined in AWS CloudFormation templates. The application artifacts are stored in an Amazon S3 bucket and deployed to the Auto Scaling group using instance user data scripts. As the application has become more complex, recent resource changes in the CloudFormation templates have caused unplanned downtime.
How should a solutions architect improve the CI/CD pipeline to reduce the likelihood that changes in the templates will cause downtime?

A. Adapt the deployment scripts to detect and report CloudFormation error conditions when performing deployments. Write test plans for a testing team to run in a non-production environment before approving the change for production.
B. Use plugins for the integrated development environment (IDE) to check the templates for errors, and use the AWS CLI to validate that the templates are correct. Adapt the deployment code to check for error conditions and generate notifications on errors. Deploy to a test environment and run a manual test plan before approving the change for production.
C. Use AWS CodeDeploy and a blue/green deployment pattern with CloudFormation to replace the user data deployment scripts. Have the operators log in to running instances and go through a manual test plan to verify the application is running as expected.
D. Implement automated testing using AWS CodeBuild in a test environment. Use CloudFormation change sets to evaluate changes before deployment. Use AWS CodeDeploy to leverage blue/green deployment patterns to allow evaluations and the ability to revert changes, if needed.

Answer: D

NEW QUESTION # 650
A company migrated an application to the AWS Cloud. The application runs on two Amazon EC2 instances behind an Application Load Balancer (ALB).
Application data is stored in a MySQL database that runs on an additional EC2 instance. The application's use of the database is read-heavy.
The application loads static content from Amazon Elastic Block Store (Amazon EBS) volumes that are attached to each EC2 instance. The static content is updated frequently and must be copied to each EBS volume.
The load on the application changes throughout the day. During peak hours, the application cannot handle all the incoming requests. Trace data shows that the database cannot handle the read load during peak hours.
Which solution will improve the reliability of the application?

A. Containerize the application. Migrate the application to an Amazon Elastic Container Service (Amazon ECS) cluster. Use the AWS Fargate launch type for the tasks that host the application.
Create a new single EBS volume for the static content. Mount the new EBS volume on the ECS cluster. Configure AWS Application Auto Scaling on the ECS cluster. Set the ECS service as a target for the ALB. Migrate the database to an Amazon RDS for MySQL Multi-AZ DB cluster.
B. Migrate the application to a set of AWS Lambda functions. Set the Lambda functions as targets for the ALB. Create a new single EBS volume for the static content. Configure the Lambda functions to read from the new EBS volume. Migrate the database to an Amazon RDS for MySQL Multi-AZ DB cluster.
C. Migrate the application to a set of AWS Step Functions state machines. Set the state machines as targets for the ALCreate an Amazon Elastic File System (Amazon EFS) file system for the static content. Configure the state machines to read from the EFS file system. Migrate the database to Amazon Aurora MySQL Serverless v2 with a reader DB instance.
D. Containerize the application. Migrate the application to an Amazon Elastic Container Service (Amazon ECS) cluster. Use the AWS Fargate launch type for the tasks that host the application.
Create an Amazon Elastic File System (Amazon EFS) file system for the static content. Mount the EFS file system to each container. Configure AWS Application Auto Scaling on the ECS cluster.Set the ECS service as a target for the ALB. Migrate the database to Amazon Aurora MySQL Serverless v2 with a reader DB instance.

Answer: D

NEW QUESTION # 651
A company is using an Amazon CloudFront distribution to distribute both static and dynamic content from a web application running behind an Application Load Balancer. The web application requires user authorization and session tracking for dynamic content. The CloudFront distribution has a single cache behavior configured to forward the Authorization, Host, and User-Agent http whitelist headers and a session cookie to the origin. All other cache behavior settings are set to their default value. A valid ACM certificate is applied to the CloudFront distribution with a matching CNAME in the distribution settings. The ACM certificate is also applied to the https listener for the Application Load Balancer. The CloudFront origin protocol policy is set to https only. Analysis of the cache statistics report shows that the miss rate for this distribution is very high.
What can the Solutions Architect do to improve the cache hit rate for this distribution without causing the SSL/TLS handshake between CloudFront and the Application Load Balancer to fail?

A. Remove the Host http header from the whitelist headers section and remove the session cookie from the whitelist cookies section for the default cache behavior. Enable automatic object compression and use Lambda@Edge viewer request events for user authorization.
B. Create two cache behaviors for static and dynamic content. Remove the User-Agent http header from the whitelist headers section on both of the cache behaviors. Remove the session cookie from the whitelist cookies section and the Authorization http header from the whitelist headers section for cache behavior configured for static content.
C. Create two cache behaviors for static and dynamic content. Remove the User-Agent and Host
http headers from the whitelist headers section on both if the cache behaviors. Remove the session cookie from the whitelist cookies section and the Authorization http header from the whitelist headers section for cache behavior configured for static content.
D. Remove the User-Agent and Authorization https headers from the whitelist headers section of the cache behavior. Then update the cache behavior to use presigned cookies for authorization.

Answer: B

Explanation:
Need to keep host header as cloudfront and elb is using the SAME ssl certificate.
