164. A company uses Amazon S3 to host a web application. Currently, the company uses a continuous integration tool running on an Amazon EC2 instance that builds and deploys the application by uploading it to an S3 bucket. A Solutions Architect needs to enhance the security of the company’s platform with the following requirements:
A build process should be run in a separate account from the account hosting the web application.
A build process should have minimal access in the account it operates in.
Long-lived credentials should not be used.

As a start, the Development team created two AWS accounts: one for the application named web account process; other is a named build account. Which solution should the Solutions Architect use to meet the security requirements?

A. In the build account, create a new IAM role, which can be assumed by Amazon EC2 only. Attach the role to the EC2 instance running the continuous integration process. Create an IAM policy to allow s3: PutObject calls on the S3 bucket in the web account. In the web account, create an S3 bucket policy attached to the S3 bucket that allows the build account to use s3:PutObject calls.
B. In the build account, create a new IAM role, which can be assumed by Amazon EC2 only. Attach the role to the EC2 instance running the continuous integration process.

B. The ECS configuration does not contain an Auto Scaling group.
C. The ECS instance task execution IAM role was modified.
D. The ECS task role was modified.

166. A mobile gaming application publishes data continuously to Amazon Kinesis Data Streams. An AWS Lambda function processes records from the data stream and writes to an Amazon DynamoDB table. The DynamoDB table has an auto scaling policy enabled with the target utilization set to 70%. For several minutes at the start and end of each day, there is a spike in traffic that often exceeds five times the normal load. The company notices the GetRecords.IteratorAgeMilliseconds metric of the Kinesis data stream temporarily spikes to over a minute for several minutes. The AWS Lambda function writes ProvisionedThroughputExceededException messages to Amazon CloudWatch Logs during these times, and some records are redirected to the dead letter queue. No exceptions are thrown by the Kinesis producer on the gaming application. What change should the company make to resolve this issue?

A. Use Application Auto Scaling to set a scaling schedule to scale out write capacity on the DynamoDB table during predictable load spikes.
B. Use Amazon CloudWatch Events to monitor the dead letter queue and invoke a Lambda function to automatically retry failed records.
C. Reduce the DynamoDB table auto scaling policy’s target utilization to 20% to more quickly respond to load spikes.
D. Increase the number of shards in the Kinesis data stream to increase throughput capacity.

167. A company has a web application that securely uploads pictures and videos to an Amazon S3 bucket. The company requires that only authenticated users are allowed to post content. The application generates a pre-signed URL that is used to upload objects through a browser interface. Most users are reporting slow upload times for objects larger than 100 MB. What can a Solutions Architect do to improve the performance of these uploads while ensuring only authenticated users are allowed to post content?

A. Set up an Amazon API Gateway with an edge-optimized API endpoint that has a resource as an S3 service proxy. Configure the PUT method for this resource to expose the S3 PutObject operation. Secure the API Gateway using a COGNITO_USER_POOLS authorizer. Have the browser interface use API Gateway instead of the presigned URL to upload objects.
B. Set up an Amazon API Gateway with a regional API endpoint that has a resource as an S3 service proxy. Configure the PUT method for this resource to expose the S3 PutObject operation. Secure the API Gateway using an AWS Lambda authorizer. Have the browser interface use API Gateway instead of the presigned URL to upload API objects.
C. Enable an S3 Transfer Acceleration endpoint on the S3 bucket. Use the endpoint when generating the presigned URL. Have the browser interface upload the objects to this URL using the S3 multipart upload API.
D. Configure an Amazon CloudFront distribution for the destination S3 bucket. Enable PUT and POST methods for the CloudFront cache behavior. Update the CloudFront origin to use an origin access identity (OAI). Give the OAI user s3:PutObject permissions in the bucket policy. Have the browser interface upload objects using the CloudFront distribution.

168. A company’s CISO has asked a Solutions Architect to re-engineer the company’s current CI/CD practices to make sure patch deployments to its application can happen as quickly as possible with minimal downtime if vulnerabilities are discovered. The company must also be able to quickly roll back a change in case of errors. The web application is deployed in a fleet of Amazon EC2 instances behind an Application Load Balancer.

E. Configure the S3 bucket policies to permit access using an aws:sourceVpce condition to match the S3 endpoint ID.

171. While debugging a backend application for an IoT system that supports globally distributed devices, a Solutions Architect notices that stale data is occasionally being sent to user devices. Devices often share data, and stale data does not cause issues in most cases. However, device operations are disrupted when a device reads the stale data after an update. The global system has multiple identical application stacks deployed in different AWS Regions. If a user device travels out of its home geographic region, it will always connect to the geographically closest AWS Region to write or read data. The same data is available in all supported AWS Regions using an Amazon DynamoDB global table. What change should be made to avoid causing disruptions in device operations?

A. Update the backend to use strongly consistent reads. Update the devices to always write to and read from their home AWS Region.

A local government client recently mandated that highly confidential documents cannot be stored outside the country. The company CIO asks a Solutions Architect to ensure the application can adapt to this new requirement. The CIO also wants to have a proper backup plan for these documents, as backups are not currently performed. What solution meets these requirements?

A. Tag documents that are not highly confidential as regular in Amazon S3. Create individual S3 buckets for each user. Upload objects to each user’s bucket. Set S3 bucket replication from these buckets to a central S3 bucket in a different AWS account and AWS Region. Configure an AWS Lambda function triggered by scheduled events in Amazon CloudWatch to delete objects that are tagged as secret in the S3 backup bucket.
B. Tag documents as either regular or secret in Amazon S3. Create an individual S3 backup bucket in the same AWS account and AWS Region. Create a cross-region S3 bucket in a separate AWS account. Set proper IAM roles to allow cross-region permissions to the S3 buckets. Configure an AWS Lambda function triggered by Amazon CloudWatch scheduled events to copy objects that are tagged as secret to the S3 backup bucket and objects tagged as cross-region S3 bucket.
C. Tag documents as either regular or secret in Amazon S3. Create an individual S3 backup bucket in the same AWS account and AWS Region. Use S3 selective cross-region replication based on object tags to move regular documents to an S3 bucket in a different AWS Region. Configure an AWS Lambda function that triggers when new S3 objects are created in the main bucket to replicate only documents tagged as secret into the S3 bucket in the same AWS Region.
D. Tag highly confidential documents as secret in Amazon S3. Create an individual S3 backup bucket in the same AWS account and AWS Region. Use S3 selective cross-region replication based on object tags to move regular documents to an S3 bucket in a different AWS Region. Create an Amazon CloudWatch Events rule for new S3 objects tagged as secret to trigger an AWS Lambda function to replicate them into a separate bucket in the same AWS Region.

173. A company has an application that runs on a fleet of Amazon EC2 instances and stores 70 GB of device data for each instance in Amazon S3. Recently, some of the S3 uploads have been failing. At the same time, the company is seeing an unexpected increase in storage data costs. The application code cannot be modified. What is the MOST efficient way to upload the device data to Amazon S3 while managing storage costs?

A. Upload device data using a multipart upload. Use the AWS CLI to list incomplete parts to address the failed S3 uploads. Enable the lifecycle policy for the incomplete multipart uploads on the S3 bucket to delete the old uploads and prevent new failed uploads from accumulating.
B. Upload device data using S3 Transfer Acceleration. Use the AWS Management Console to address the failed S3 uploads. Use the Multi-Object Delete operation nightly to delete the old uploads.
C. Upload device data using a multipart upload. Use the AWS Management Console to list incomplete parts to address the failed S3 uploads. Configure a lifecycle policy to archive continuously to Amazon S3 Glacier.
D. Upload device data using S3 Transfer Acceleration. Use the AWS Management Console to list incomplete parts to address the failed S3 uploads. Enable the lifecycle policy for the incomplete multipart uploads on the S3 bucket to delete the old uploads and prevent new failed uploads from accumulating.

174. 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:

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 policy?

A. Create an explicit deny statement for each AWS service that should be constrained.
B. Remove the FullAWSAccess SCP from the Developer account’s OU.

Which solution will increase the reliability of all releases?

A. Implement a blue/green deployment methodology.
B. Implement the canary release methodology.
C. Configure Amazon CloudFront to serve all requests from the cache while deploying the updates.
D. Implement the all at once deployment methodology.

176. During a security audit of a Service team’s application, a Solutions Architect discovers that a username and password for an Amazon RDS database and a set of AWS IAM user credentials can be viewed in the AWS Lambda function code. The Lambda function uses the username and password to run queries on the database, and it uses the IAM credentials to call AWS services in a separate management account. The Solutions Architect concerned that the credentials could grant inappropriate access to anyone who can view the Lambda code. The management account and the Service team’s account are in separate AWS Organizations organizational units (OUs).
Which combination of changes should the Solutions Architect make to improve the solution’s security? (Choose two.)

A. Configure Lambda to assume a role in the management account with appropriate access to AWS.
B. Configure Lambda to use the stored database credentials in AWS Secrets Manager and enable automatic rotation.
C. Create a Lambda function to rotate the credentials every hour by deploying a new Lambda version with the updated credentials.
D. Use an SCP on the management account’s OU to prevent IAM users from accessing resources in the Service team’s account. E. Enable AWS Shield Advanced on the management account to shield sensitive resources from unauthorized IAM access.

177. A company is having issues with a newly deployed serverless infrastructure that uses Amazon API Gateway, Amazon Lambda, and Amazon DynamoDB. In a steady state, the application performs as expected. However, during peak load, tens of thousands of simultaneous invocations are needed and user requests fail multiple times before succeeding. The company has checked the logs for each component, focusing specifically on Amazon CloudWatch Logs for Lambda. There are no errors logged by the services or applications. What might cause this problem?

A.Lambda has very low memory assigned, which causes the function to fail at peak load.
B.Lambda is in a subnet that uses a NAT gateway to reach out of the internet, and the function instance does not have sufficient Amazon EC2 resources in the VPC to scale with the load.
C. The throttle limit set on API Gateway is very low. During peak load, the additional requests are not making their way through to Lambda.
D. DynamoDB is set up in an auto scaling mode. During peak load, DynamoDB adjusts capacity and throughput behind the scenes, which is causing the temporary downtime. Once the scaling completes, the retries go through successfully.

178. A large company with hundreds of AWS accounts has a newly established centralized internal process for purchasing new or modifying existing Reserved Instances. This process requires all business units that want to purchase or modify Reserved Instances to submit requests to a dedicated team for procurement or execution. Previously, business units would directly purchase or modify Reserved Instances in their own respective AWS accounts autonomously. Which combination of steps should be taken to proactively enforce the new process in the MOST secure way possible? (Choose two.)

A. Ensure all AWS accounts are part of an AWS Organizations structure operating in all features mode.
B. Use AWS Config to report on the attachment of an IAM policy that denies access to the ec2:PurchaseReservedInstancesOffering and ec2:ModifyReservedInstances actions.
C. In each AWS account, create an IAM policy with a DENY rule to the ec2:PurchaseReservedInstancesOffering and ec2:ModifyReservedInstances actions.
D. Create an SCP that contains a deny rule to the ec2:PurchaseReservedInstancesOffering and ec2:ModifyReservedInstances actions. Attach the SCP to each organizational unit (OU) of the AWS Organizations structure.
E. Ensure that all AWS accounts are part of an AWS Organizations structure operating in consolidated billing features mode.

179. A Solutions Architect wants to make sure that only AWS users or roles with suitable permissions can access a new Amazon API Gateway endpoint. The Solutions Architect wants an end-to-end view of each request to analyze the latency of the request and create service maps. How can the Solutions Architect design the API Gateway access control and perform request inspections?

A. For the API Gateway method, set the authorization to AWS_IAM. Then, give the IAM user or role execute-api:Invoke permission on the REST API resource. Enable the API caller to sign requests with AWS Signature when accessing the endpoint. Use AWS X-Ray to trace and analyze user requests to API Gateway.
B. For the API Gateway resource, set CORS to enabled and only return the company’s domain in Access-Control-Allow-Origin headers. Then, give the IAM user or role execute-api:Invoke permission on the REST API resource. Use Amazon CloudWatch to trace and analyze user requests to API Gateway.
