A solutions architect needs to advise a company on how to migrate its on-premises data processing application to the AWS Cloud. Currently, users upload input files through a web portal. The web server then stores the uploaded files on NAS and messages the processing server over a message queue. Each media file can take up to 1 hour to process. The company has determined that the number of media files awaiting processing is significantly higher during business hours, with the number of files rapidly declining after business hours. What is the MOST cost-effective migration recommendation?

A company’s processing team has an AWS account with a production application. The application runs on Amazon EC2 instances behind a Network Load Balancer (NLB). The EC2 instances are hosted in private subnets in a VPC in the eu- west- 1 Region. The VPC was assigned the CIDR block of 10.0.0.0/16.

Question 521

A company used Amazon EC2 instances to deploy a web fleet to host a blog site. The EC2 instances are behind an Application Load Balancer (ALB) and are configured in an Auto Scaling group. The web application stores all blog content on an Amazon EFS volume.

The company recently added a feature for bloggers to add video to their posts, attracting 10 times the previous user traffic. At peak times of day, users report buffering and timeout issues while attempting to reach the site or watch videos. Which is the MOST cost-efficient and scalable deployment that will resolve the issues for users?

Reconfigure Amazon EFS to enable maximum I/O.

Update the blog site to use instance store volumes for storage. Copy the site contents to the volumes at launch and to Amazon S3 at shutdown.

Configure an Amazon CloudFront distribution. Point the distribution to an S3 bucket, and migrate the videos from EFS to Amazon S3.

Set up an Amazon CloudFront distribution for all site contents, and point the distribution at the ALB.

Question 522

You are the new IT architect in a company that operates a mobile sleep tracking application.

When activated at night, the mobile app is sending collected data points of 1 kilobyte every 5 minutes to your backend. The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB table. Every morning, you scan the table to extract and aggregate last night's data on a per user basis, and store the results in Amazon S3. Users are notified via Amazon SNS mobile push notifications that new data is available, which is parsed and visualized by the mobile app.

Currently you have around 100k users who are mostly based out of North America.

You have been tasked to optimize the architecture of the backend system to lower cost.

What would you recommend? (Choose two.)

Have the mobile app access Amazon DynamoDB directly Instead of JSON files stored on Amazon S3.

Write data directly into an Amazon Redshift cluster replacing both Amazon DynamoDB and Amazon S3.

Introduce an Amazon SQS queue to buffer writes to the Amazon DynamoDB table and reduce provisioned write throughput.

Introduce Amazon Elasticache to cache reads from the Amazon DynamoDB table and reduce provisioned read throughput.

Create a new Amazon DynamoDB table each day and drop the one for the previous day after its data is on Amazon S3.

Question 524

What happens when Dedicated instances are launched into a VPC?

If you launch an instance into a VPC that has an instance tenancy of dedicated, you must manually create a Dedicated instance.

If you launch an instance into a VPC that has an instance tenancy of dedicated, your instance is created as a Dedicated instance, only based on the tenancy of the instance.

If you launch an instance into a VPC that has an instance tenancy of dedicated, your instance is automatically a Dedicated instance, regardless of the tenancy of the instance.

None of these are true.

Question 525

A company is deploying a third-party firewall appliance solution from AWS Marketplace to monitor and protect traffic that leaves the company’s AWS environments. The company wants to deploy this appliance into a shared services VPC and route all outbound internet-bound traffic through the appliances.

A solutions architect needs to recommend a deployment method that prioritizes reliability and minimizes failover time between firewall appliances within a single AWS Region. The company has set up routing from the shared services VPC to other VPCs.

Which steps should the solutions architect recommend to meet these requirements? (Choose three.)

Deploy two firewall appliances into the shared services VPC, each in a separate Availability Zone.

Create a new Network Load Balancer in the shared services VPC. Create a new target group, and attach it to the new Network Load Balancer. Add each of the firewall appliance instances to the target group.

Create a new Gateway Load Balancer in the shared services VPCreate a new target group, and attach it to the new Gateway Load Balancer. Add each of the firewall appliance instances to the target group.

Create a VPC interface endpoint. Add a route to the route table in the shared services VPC. Designate the new endpoint as the next hop for traffic that enters the shared services VPC from other VPCs.

Question 526

A large global financial services company has multiple business units. The company wants to allow Developers to try new services, but there are multiple compliance requirements for different workloads. The Security team is concerned about the access strategy for on-premises and AWS implementations. They would like to enforce governance for AWS services used by business teams for regulatory workloads, including Payment Card Industry (PCI) requirements. Which solution will address the Security team’s concerns and allow the Developers to try new services?

Implement a strong identity and access management model that includes users, groups, and roles in various AWS accounts. Ensure that centralized AWS CloudTrail logging is enabled to detect anomalies. Build automation with AWS Lambda to tear down unapproved AWS resources for governance.

Build a multi-account strategy based on business units, environments, and specific regulatory requirements. Implement SAML-based federation across all AWS accounts with an on-premises identity store. Use AWS Organizations and build organizational units (OUs) structure based on regulations and service governance. Implement service control policies across OUs.

Implement a multi-account strategy based on business units, environments, and specific regulatory requirements. Ensure that only PCI-compliant services are approved for use in the accounts. Build IAM policies to give access to only PCIcompliant services for governance.

Build one AWS account for the company for strong security controls. Ensure that all the service limits are raised to meet company scalability requirements. Implement SAML federation with an onpremises identity store, and ensure that only approved services are used in the account.

Question 528

A company asks a solution architect to optimize the cost of a solution. The solution handles requests from multiple customers. The solution includes a multi-tier architecture that uses Amazon API Gateway, AWS Lambda, AWS Fargate, Amazon Simple Queue Service (Amazon SQS), and Amazon EC2.

In the current setup, requests go through API Gateway to Lambda and either start a container in Fargate or push a message to an SQS queue. An EC2 Fleet provides EC2 instances that serve as workers for the SQS queue. The EC2 Fleet scales based on the number of items in the SQS queue.

Which combination of steps should the solutions architect recommend to reduce cost the MOST? (Choose three.)

Determine the minimum number of EC2 instances that are needed during a day. Reserve this number of instances in a 3- year plan with payment all upfront.

Examine the last 6 months of compute utilization across the services. Use this information to determine the needed compute for the solution. Commit to a Savings Plan for this amount.

Determine the average number of EC2 instances that are needed during a day. Reserve this number of instances in a 3- year plan with payment all upfront.

Remove the SQS queue from the solution and from the solution infrastructure.

Change the solution so that it runs as a container instead of on EC2 instances. Configure Lambda to start up the solution in Fargate by using environment variables to give the solution the message.

Change the Lambda function so that it posts the message directly to the EC2 instances through an Application Load Balancer.
