Question # 169

Question:

A company has an application that stores user-uploaded videos in an Amazon S3 bucket using S3 Standard storage. Users access videos frequently for the first 180 days, and rarely after that. Most videos are over 100 MB. Users often have poor internet connectivity, and the company uses multipart uploads.

A solutions architect needs tooptimize S3 storage costs.

Which combination of actions will meet these requirements? (Select TWO.)

Configure the S3 bucket to be a Requester Pays bucket.

Use S3 Transfer Acceleration to upload the videos.

Create a lifecycle rule to expireincomplete multipart uploadsafter 7 days.

Create a lifecycle rule to transition objects toS3 Glacier Instant Retrieval after 1 day.

Create a lifecycle rule to transition objects toS3 Standard-IA after 180 days.

Question # 170

A company has registered 10 new domain names. The company uses the domains for online marketing. The company needs a solution that will redirect online visitors to a specific URL for each domain. All domains and target URLs are defined in a JSON document. All DNS records are managed by Amazon Route 53.

A solutions architect must implement a redirect service that accepts HTTP and HTTPS requests.

Which combination of steps should the solutions architect take to meet these requirements with the LEAST amount of operational effort? (Choose three.)

Create a dynamic webpage that runs on an Amazon EC2 instance. Configure the webpage to use the JSON document in combination with the event message to look up and respond with a redirect URL.

Create an Application Load Balancer that includes HTTP and HTTPS listeners.

Create an AWS Lambda function that uses the JSON document in combination with the event message to look up and respond with a redirect URL.

Use an Amazon API Gateway API with a custom domain to publish an AWS Lambda function.

Create an Amazon CloudFront distribution. Deploy a Lambda@Edge function.

Create an SSL certificate by using AWS Certificate Manager (ACM). Include the domains as Subject Alternative Names.

Question # 171

A company wants to migrate its on-premises application to AWS. The database for the application stores structured product data and temporary user session data. The company needs to decouple the product data from the user session data. The company also needs to implement replication in another AWS Region for disaster recovery.

Which solution will meet these requirements with the HIGHEST performance?

Create an Amazon RDS DB instance with separate schemas to host the product data and the user session data. Configure a read replica for the DB instance in another Region.

Create an Amazon RDS DB instance to host the product data. Configure a read replica for the DB instance in another Region. Create a global datastore in Amazon ElastiCache for Memcached to host the user session data.

Create two Amazon DynamoDB global tables. Use one global table to host the product data Use the other global table to host the user session data. Use DynamoDB Accelerator (DAX) for caching.

Create an Amazon RDS DB instance to host the product data. Configure a read replica for the DB instance in another Region. Create an Amazon DynamoDB global table to host the user session data

Question # 172

A company hosts a web application on AWS in the us-east-1 Region The application servers are distributed across three Availability Zones behind an Application Load Balancer. The database is hosted in a MySQL database on an Amazon EC2 instance A solutions architect needs to design a Cross-Region data recovery solution using AWS services with an RTO of less than 5 minutes and an RPO of less than 1 minute. The solutions architect is deploying application servers in us-west-2, and has configured Amazon Route 53 hearth checks and DNS failover to us-west-2

Which additional step should the solutions architect take?

Migrate the database to an Amazon RDS tor MySQL instance with a cross-Region read replica in us-west-2

Migrate the database to an Amazon Aurora global database with the primary in us-east-1 and the secondary in us-west-2

Migrate the database to an Amazon RDS for MySQL instance with a Multi-AZ deployment.

Create a MySQL standby database on an Amazon EC2 instance in us-west-2

Question # 173

A company hosts an intranet web application on Amazon EC2 instances behind an Application Load Balancer (ALB). Currently, users authenticate to the application against an internal user database.

The company needs to authenticate users to the application by using an existing AWS Directory Service for Microsoft Active Directory directory. All users with accounts in the directory must have access to the application.

Which solution will meet these requirements?

Create a new app client in the directory. Create a listener rule for the ALB. Specify the authenticate-oidc action for the listener rule. Configure the listener rule with the appropriate issuer, client ID and secret, and endpoint details for the Active Directory service. Configure the new app client with the callback URL that the ALB provides.

Configure an Amazon Cognito user pool. Configure the user pool with a federated identity provider (IdP) that has metadata from the directory. Create an app client. Associate the app client with the user pool. Create a listener rule for the ALB. Specify the authenticate-cognito action for the listener rule. Configure the listener rule to use the user pool and app client.

Add the directory as a new 1AM identity provider (IdP). Create a new 1AM role that has an entity type of SAML 2.0 federation. Configure a role policy that allows access to the ALB. Configure the new role as the default authenticated user role for the IdP. Create a listener rule for the ALB. Specify the authenticate-oidc action for the listener rule.

Enable AWS 1AM Identity Center (AWS Single Sign-On). Configure the directory as an external identity provider (IdP) that uses SAML. Use the automatic provisioning method. Create a new 1AM role that has an entity type of SAML 2.0 federation. Configure a role policy that allows access to the ALB. Attach the new role to all groups. Create a listener rule for the ALB. Specify the authenticate-cognito action for the listener rule.

Answer:

Explanation:

The correct solution is to use the authenticate-oidc action for the ALB listener rule and configure it with the details of the AWS Directory Service for Microsoft Active Directory directory. This way, the ALB can use OpenID Connect (OIDC) to authenticate users against the directory and grant them access to the intranet web application. The app client in the directory is used to register the ALB as an OIDC client and provide the necessary credentials and endpoints. The callback URL is the URL that the ALB redirects the user to after a successful authentication. This solution does not require any additional services or roles, and it leverages the existing directory accounts for all users.

The other solutions are incorrect because they either use the wrong action for the ALB listener rule, or they involve unnecessary or incompatible services or roles. For example:

Solution B is incorrect because it uses Amazon Cognito user pool, which is a separate user directory service that does not integrate with AWS Directory Service for Microsoft Active Directory. To use this solution, the company would have to migrate or synchronize their users from the directory to the user pool, which is not required by the question. Moreover, the authenticate-cognito action for the ALB listener rule only works with Amazon Cognito user pools, not with federated identity providers (IdPs) that have metadata from the directory.

Solution C is incorrect because it uses IAM as an identity provider (IdP), which is not compatible with AWS Directory Service for Microsoft Active Directory. IAM can only be used as an IdP for web identity federation, which allows users to sign in with social media or other third-party IdPs, not with Active Directory. Moreover, the authenticate-oidc action for the ALB listener rule requires an OIDC IdP, not a SAML 2.0 federation IdP, which is what IAM provides.

Solution D is incorrect because it uses AWS IAM Identity Center (AWS Single Sign-On), which is a service that simplifies the management of SSO access to multiple AWS accounts and business applications. This service is not needed for the scenario in the question, which only involves a single intranet web application. Moreover, the authenticate-cognito action for the ALB listener rule does not work with external IdPs that use SAML, such as AWS IAM Identity Center.
