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?

A Solutions Architect must establish a patching plan for a large mixed fleet of Windows and Linux servers. The patching plan must be implemented securely, be audit ready, and comply with the company's business requirements. Which option will meet these requirements with MINIMAL effort?

A company has a serverless application comprised of Amazon CloudFront, Amazon API Gateway, and

AWS Lambda functions. The current deployment process of the application code is to create a new version

number of the Lambda function and run an AWS CLI script to update. If the new function version has errors,

another CLI script reverts by deploying the previous working version of the function. The company would like

to decrease the time to deploy new versions of the application logic provided by the Lambda functions, and also

reduce the time to detect and revert when errors are identified.

How can this be accomplished?

A company will several AWS accounts is using AWS Organizations and service control policies (SCPs). An Administrator created the following SCP and has attached it to an organizational unit (OU) that contains AWS account 1111-1111-1111:

（含图）

{

"Version": "2012-10-27" "Statement": [

{

"Side": "AllowsAllActions",

"Effect": "Allow",

"Action": "*",

"Resource": "*"

{

"Side": "DenyCloudTrail",

"Effect": "Deny",

"Action": "CloudTrail:*",

"Resource": "*"

}

]

}

Developers working in account 1111-1111-1111 complain that they cannot create Amazon S3 buckets. How should the Administrator address this problem?

A finance company is running its business-critical application on current-generation Linux EC2 instances. The application includes a self-managed MySQL database performing heavy I/O operations. The application is working fine to handle a moderate amount of traffic during the month. However, it slows down during the final three days of each month due to month-end reporting, even though the company is using Elastic Load Balancers and Auto Scaling within its infrastructure to meet the increased demand. Which of the following actions would allow the database to handle the month-end load with the LEAST impact on performance?

A company is using AWS CloudFormation to deploy its infrastructure. The company is concerned that, if a production CloudFormation stack is deleted, important data stored in Amazon RDS databases or Amazon EBS volumes might also be deleted. How can the company prevent users from accidentally deleting data in this way?

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?

A Solutions Architect is designing the data storage and retrieval architecture for a new application that a company will be launching soon. The application is designed to ingest millions of small records per minute from devices all around the world. Each record is less than 4 KB in size and needs to be stored in a durable location where it can be retrieved with low latency. The data is ephemeral and the company is required to store the data for 120 days only, after which the data can be deleted.The Solutions Architect calculates that, during the course of a year, the storage requirements would be about 10-15 TB. Which storage strategy is the MOST cost-effective and meets the design requirements?

An enterprise company wants to allow its Developers to purchase third-party software through AWS Marketplace. The company uses an AWS Organizations account structure with full features enabled, and has a shared services account in each organizational unit (OU) that will be used by Procurement Managers. The Procurement team's policy indicates that Developers should be able to obtain third-party software from an approved list only and use Private Marketplace in AWS Marketplace to achieve this requirement. The Procurement team wants administration of Private Marketplace to be restricted to a role named procurement- manager-role, which could be assumed by Procurement Managers. Other IAM users, groups, roles, and account administrators in the company should be denied Private Marketplace administrative access.

What is the MOST efficient way to design an architecture to meet these requirements?

A company is hosting a three-tier web application in an on-premises environment. Due to a recent surge in traffic that resulted in downtime and a significant financial impact, company management has ordered that the application be moved to AWS. The application is written in NET and has a dependency on a MySQL database. a Solutions Architect must design a scalable and highly available solution to meet the demand of 200, 000 daily users.

Which steps should the Solutions Architect take to design an appropriate solution?

A company is in the process of implementing AWS Organizations to constrain its Developers to use only Amazon EC2, Amazon S3,and Amazon DynamoDB. The Developers account resides in a dedicated organizational unit (OU). The Solutions Architect has implemented the following SCP on the Developers account:

（含图）

When this policy is deployed. IAM users in the Developers account are still able to use AWS services that are not listed in the policy

What should the solutions Architect do to eliminate the developers' ability to use services outside the scope of this poll?

A company is developing a new service that will be accessed using TCP on a static port. A Solutions Architect must ensure that the service is highly available, has redundancy across Availability Zones, and is accessible using the DNS name my.service.com, which is publicly accessible. The service must use fixed address assignments SO other companies can add the addresses to their allow lists. Assuming that resources are deployed in multiple Availability Zones in a single Region, which solution will meet these requirements?

A company has a web application that allows users to upload short videos. The videos are stored on Amazon EBS volumes and analyzed by custom recognition software for categorization. The website contains static content that has variable traffic with peaks in certain months. The architecture consists of Amazon EC2 instances running in an Auto Scaling group for the web application and EC2 instances running in an Auto Scaling group to process an Amazon SQS queue. The company wants to re- architect the application to reduce operational overhead using AWS managed services.where possible and remove dependencies on third-party software.

Which solution meets these requirements?

A company plans to refactor a monolithic application into a modern application design deployed on AWS. The CI/CD pipeline needs to be upgraded to support the modern design for the application with the following requirements:

--It should allow changes to be released several times every hour.

--It should be able to roll back the changes as quickly as possible.

Which design will meet these requirements?

The company user AWS Organizations with a single OU named Production to manage multiple accounts.All accounts are members of the Production OU Administrators use deny list SCPs in the root of the organization to manage access to restricted services.

The company recently acquired a new business unit and invited the new unit' s existing AWS account to the organization Once on boarded,the administrators of the new business unit discovered that they are not able to update existing AWS Config rules to meet the company' s policies.

Which option will allow administrators to make changes and continue to enforce the current policies without introducing additional long-term maintenance?

A North American company with headquarters on the East Coast is deploying a new web application running on Amazon EC2 in the us-east-1 Region. The application should dynamically scale to meet user demand and maintain resiliency. Additionally, the application must have disaster recovery capabilities in an active- passive configuration with the us-west-1 Region.

Which steps should a solutions architect take after creating a VPC in the us-east-1 Region?

A company built an application based on AWS Lambda deployed in an AWS CloudFormation stack. The last production release of the web application introduced an issue that resulted in an outage lasting several minutes. A solutions architect must adjust the deployment process to support a canary release.

Which solution will meet these requirements?

An AWS partners company it building a service in AWS Organizations using its organization named org1. This service requires the partner company to have access to AWS resources in a customer account,which is in a separate organization named org2.The company must establish least privilege security access using an API or command line foot to the customer account.

What is the MOST secure way to allow org1 to access resources in org2?

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 security engineer determined that an existing application retrieves credentials to an Amazon RDS for MySQL database from an encrypted file in Amazon S3 For the next version of the application, the security engineer wants to implement the following application design changes to improve security:

--The database must use strong, randomly generated passwords stored in a secure AWS managed service.

--The application resources must be deployed through AWS CloudFormation.

--The application must rotate credentials for the database every 90 days. A solutions architect will generate a CloudFormation template to deploy the application.

Which resources specified in the CloudFormation template will meet the security engineer's requirements with the LEAST amount of operational overhead?
