Question # 65

A large education company recently introduced Amazon Workspaces to provide access to internal applications across multiple universities. The company is storing user profiles on an Amazon FSx (or Windows File Server file system. The tile system is configured with a DNS alias and is connected to a self-managed Active Directory. As more users begin to use the Workspaces, login time increases to unacceptable levels.

An investigation reveals a degradation in performance of the file system. The company created the file system on HDD storage with a throughput of 16 MBps. A solutions architect must improve the performance of the file system during a defined maintenance window.

What should the solutions architect do to meet these requirements with the LEAST administrative effort?

Use AWS Backup to create a point-ln-lime backup of the file system. Restore the backup to a new FSx for Windows File Server file system. Select SSD as the storage type Select 32 MBps as the throughput capacity. When the backup and restore process Is completed, adjust the DNS alias accordingly. Delete the original file system.

Disconnect users from the file system. In the Amazon FSx console, update the throughput capacity to 32 MBps. Update the storage type to SSD. Reconnect users to the file system.

Deploy an AWS DataSync agent onto a new Amazon EC2 Instance. Create a task. Configure the existing file system as the source location. Configure a new FSx for Windows File Server file system with SSD storage and 32 MBps of throughput as the target location. Schedule the task. When the task is completed, adjust the DNS alias accordingly. Delete the original file system.

Enable shadow copies on the existing file system by using a Windows PowerShell command. Schedule the shadow copy job to create a point-in-time backup of the file system. Choose to restore previous versions. Create a new FSx for Windows File Server file system with SSD storage and 32 MBps of throughput. When the copy job is completed, adjust the DNS alias. Delete the original file system.

Question # 66

A company has a collaborative document editing application that allows multiple users to simultaneously edit shared documents. The documents are stored as JSON objects in Amazon S3. The company needs to prevent data loss when multiple users modify the same document simultaneously. The solution must ensure that only the first write operation to finish successfully modifies the document. The solution must handle thousands of concurrent editors across multiple AWS Regions and must resolve conflicts automatically.

Which solution will meet these requirements?

Deploy an S3 bucket and enable versioning. Configure S3 event notifications to invoke an AWS Lambda function in response to PutObject events. Configure the function to track document versions in an Amazon DynamoDB table and to use conditional writes to resolve conflicts.

Deploy an S3 bucket. Configure conditional writes to use If-Match headers and entity tags (ETags). Configure an AWS Lambda function to detect editing conflicts based on Amazon S3 responses to writes. Configure the Lambda function to send retry messages to an Amazon SQS queue with a delay.

Deploy an S3 bucket and enable S3 Object Lock in compliance mode. Use AWS Step Functions to retry sequential document updates by using exponential backoff.

Deploy an S3 bucket and enable multipart uploads. Use AWS Batch jobs to make document updates. Use Amazon ElastiCache for Redis as a distributed lock mechanism across Regions.

Question # 68

A company has developed a mobile game. The backend for the game runs on several virtual machines located in an on-premises data center. The business logic is exposed using a REST API with multiple functions. Player session data is stored in central file storage. Backend services use different API keys for throttling and to distinguish between live and test traffic.

The load on the game backend varies throughout the day. During peak hours, the server capacity is not sufficient. There are also latency issues when fetching player session data. Management has asked a solutions architect to present a cloud architecture that can handle the game ' s varying load and provide low-latency data access. The API model should not be changed.

Which solution meets these requirements?

Implement the REST API using a Network Load Balancer (NLB). Run the business logic on an Amazon EC2 instance behind the NLB. Store player session data in Amazon Aurora Serverless.

Implement the REST API using an Application Load Balancer (ALB). Run the business logic in AWS Lambda. Store player session data in Amazon DynamoDB with on-demand capacity.

Implement the REST API using Amazon API Gateway. Run the business logic in AWS Lambda. Store player session data in Amazon DynamoDB with on- demand capacity.

Implement the REST API using AWS AppSync. Run the business logic in AWS Lambda. Store player session data in Amazon Aurora Serverless.

Question # 69

A company hosts an application on AWS. The application reads and writes objects that are stored in a single Amazon S3 bucket. The company must modify the application to deploy the application in two AWS Regions.

Which solution will meet these requirements with the LEAST operational overhead?

Set up an Amazon CloudFront distribution with the S3 bucket as an origin. Deploy the application to a second Region Modify the application to use the CloudFront distribution. Use AWS Global Accelerator to access the data in the S3 bucket.

Create a new S3 bucket in a second Region. Set up bidirectional S3 Cross-Region Replication (CRR) between the original S3 bucket and the new S3 bucket. Configure an S3 Multi-Region Access Point that uses both S3 buckets. Deploy a modified application to both Regions.

Create a new S3 bucket in a second Region Deploy the application in the second Region. Configure the application to use the new S3 bucket. Set up S3 Cross-Region Replication (CRR) from the original S3 bucket to the new S3 bucket.

Set up an S3 gateway endpoint with the S3 bucket as an origin. Deploy the application to a second Region. Modify the application to use the new S3 gateway endpoint. Use S3 Intelligent-Tiering on the S3 bucket.

Question # 70

An e-commerce company is revamping its IT infrastructure and is planning to use AWS services. The company ' s CIO has asked a solutions architect to design a simple, highly available, and loosely coupled order processing application. The application is responsible for receiving and processing orders before storing them in an Amazon DynamoDB table. The application has a sporadic traffic pattern and should be able to scale during marketing campaigns to process the orders with minimal delays.

Which of the following is the MOST reliable approach to meet the requirements?

Receive the orders in an Amazon EC2-hosted database and use EC2 instances to process them.

Receive the orders in an Amazon SQS queue and invoke an AWS Lambda function to processthem.

Receive the orders using the AWS Step Functions program and launch an Amazon ECS container to process them.

Receive the orders in Amazon Kinesis Data Streams and use Amazon EC2 instances to process them.

Full Access

Answer:

Explanation:

The best option is to use Amazon SQS and AWS Lambda to create a serverless order processing application. Amazon SQS is a fully managed message queue service that can decouple the order receiving and processing components, making the application more scalable and fault-tolerant. AWS Lambda is a serverless compute service that can automatically scale to handle the incoming messages from the SQS queue and process them according to the business logic. AWS Lambda can also integrate with Amazon DynamoDB to store the processed orders in a fast and flexible NoSQL database. This approach eliminates the need to provision, manage, or scale any servers or containers, and reduces the operational overhead and cost.

Option A is not reliable because using an EC2-hosted database to receive the orders introduces a single point of failure and a scalability bottleneck. EC2 instances also require more management and configuration than serverless services.

Option C is not reliable because using AWS Step Functions to receive the orders adds unnecessary complexity and cost to the application. AWS Step Functions is a service that coordinates multiple AWS services into a serverless workflow, but it is not designed to handle high-volume, sporadic, or unpredictable traffic patterns. AWS Step Functions also charges per state transition, which can be expensive for a large number of orders. Launching an ECS container to process each order also requires more resources and management than invoking a Lambda function.

Option D is not reliable because using Amazon Kinesis Data Streams to receive the orders is not suitable for this use case. Amazon Kinesis Data Streams is a service that enables real-time processing of streaming data at scale, but it is not meant for asynchronous message queuing. Amazon Kinesis Data Streams requires consumers to poll the data from the stream, which can introduce latency and complexity. Amazon Kinesis Data Streams also charges per shard hour, which can be expensive for a sporadic traffic pattern.

Question # 71

Company A recently acquired Company B. Company A requires that Company B use Amazon WorkSpaces in a separate member AWS account that Company A manages. Company A uses AWS Organizations with all features enabled. Company A also uses AWS IAM Identity Center with a SAML-based identity source for access to Company Aâ€™s AWS accounts. Company B has its own SAML-based identity provider IdP.

Company A requires that authentication to WorkSpaces use only Company Bâ€™s own IdP.

Which solution will meet these requirements?

Configure a WorkSpaces application from the IAM Identity Center application catalog. Set up the SAML metadata and certificate from Company Bâ€™s IdP. Enable WorkSpaces to authenticate by using SAML 2.0.

Configure IAM Identity Center with a second identity source. Configure attributes for access control to identify users from Company B. Create a new permission set that grants access to WorkSpaces to users with the correct attribute.

Configure an IAM SAML IdP in the member AWS account. Create IAM roles in the member AWS account with a trust policy that allows the AssumeRoleWithSAML API operation with permissions for WorkSpaces. Create an SCP that prevents IAM roles from the member AWS account from assuming roles in other accounts. Apply the SCP to the root OU.

Enable the creation of account instances in member accounts. Configure an IAM Identity Center account instance in the member AWS account. Configure the identity source to be the SAML-based IdP of Company B. Configure WorkSpaces to use the account instance as its authentication source.

Question # 72

A company is planning to migrate its on-premises transaction-processing application to AWS. The application runs inside Docker containers that are hosted on VMS in the company ' s data center. The Docker containers have shared storage where the application records transaction data.

The transactions are time sensitive. The volume of transactions inside the application is unpredictable. The company must implement a low-latency storage solution that will automatically scale throughput to meet increased demand. The company cannot develop the application further and cannot continue to administer the Docker hosting environment.

How should the company migrate the application to AWS to meet these requirements?

Migrate the containers that run the application to Amazon Elastic Kubernetes Service (Amazon EKS). Use Amazon S3 to store the transaction data that the containers share.

Migrate the containers that run the application to AWS Fargate for Amazon Elastic Container Service (Amazon ECS). Create an Amazon Elastic File System (Amazon EFS) file system. Create a Fargate task definition. Add a volume to the task definition to point to the EFS file system

Migrate the containers that run the application to AWS Fargate for Amazon Elastic Container Service (Amazon ECS). Create an Amazon Elastic Block Store (Amazon EBS) volume. Create a Fargate task definition. Attach the EBS volume to each running task.

Launch Amazon EC2 instances. Install Docker on the EC2 instances. Migrate the containers to the EC2 instances. Create an Amazon Elastic File System (Amazon EFS) file system. Add a mount point to the EC2 instances for the EFS file system.
