Question # 89

A company has a data ingestion workflow that includes the following components:

â€¢ An Amazon Simple Notation Service (Amazon SNS) topic that receives notifications about new data deliveries

â€¢ An AWS Lambda function that processes and stores the data

The ingestion workflow occasionally fails because of network connectivity issues. When tenure occurs the corresponding data is not ingested unless the company manually reruns the job. What should a solutions architect do to ensure that all notifications are eventually processed?

Configure the Lambda function (or deployment across multiple Availability Zones

Modify me Lambda functions configuration to increase the CPU and memory allocations tor the (unction

Configure the SNS topic's retry strategy to increase both the number of retries and the wait time between retries

Configure an Amazon Simple Queue Service (Amazon SQS) queue as the on failure destination Modify the Lambda function to process messages in the queue

Question # 90

An application runs on Amazon EC2 instances across multiple Availability Zones The instances run in an Amazon EC2 Auto Scaling group behind an Application Load Balancer The application performs best when the CPU utilization of the EC2 instances is at or near 40%.

What should a solutions architect do to maintain the desired performance across all instances in the group?

Use a simple scaling policy to dynamically scale the Auto Scaling group

Use a target tracking policy to dynamically scale the Auto Scaling group

Use an AWS Lambda function to update the desired Auto Scaling group capacity.

Use scheduled scaling actions to scale up and scale down the Auto Scaling group

Question # 91

A new employee has joined a company as a deployment engineer. The deployment engineer will be using AWS CloudFormation templates to create multiple AWS resources. A solutions architect wants the deployment engineer to perform job activities while following the principle of least privilege.

Which steps should the solutions architect do in conjunction to reach this goal? (Select two.)

Have the deployment engineer use AWS account roof user credentials for performing AWS CloudFormation stack operations.

Create a new IAM user for the deployment engineer and add the IAM user to a group that has the PowerUsers IAM policy attached.

Create a new IAM user for the deployment engineer and add the IAM user to a group that has the Administrate/Access IAM policy attached.

Create a new IAM User for the deployment engineer and add the IAM user to a group that has an IAM policy that allows AWS CloudFormation actions only.

Create an IAM role for the deployment engineer to explicitly define the permissions specific to the AWS CloudFormation stack and launch stacks using Dial IAM role.

Question # 92

A company wants to run applications in containers in the AWS Cloud. These applications are stateless and can tolerate disruptions within the underlying infrastructure. The company needs a solution that minimizes cost and operational overhead.

What should a solutions architect do to meet these requirements?

Use Spot Instances in an Amazon EC2 Auto Scaling group to run the application containers.

Use Spot Instances in an Amazon Elastic Kubernetes Service (Amazon EKS) managed node group.

Use On-Demand Instances in an Amazon EC2 Auto Scaling group to run the application containers.

Use On-Demand Instances in an Amazon Elastic Kubernetes Service (Amazon EKS) managed node group.

Question # 93

A company is migrating an application from on-premises servers to Amazon EC2 instances. As part of the migration design requirements, a solutions architect must implement infrastructure metric alarms. The company does not need to take action if CPU utilization increases to more than 50% for a short burst of time. However, if the CPU utilization increases to more than 50% and read IOPS on the disk are high at the same time, the company needs to act as soon as possible. The solutions architect also must reduce false alarms.

What should the solutions architect do to meet these requirements?

Create Amazon CloudWatch composite alarms where possible.

Create Amazon CloudWatch dashboards to visualize the metrics and react to issues quickly.

Create Amazon CloudWatch Synthetics canaries to monitor the application and raise an alarm.

Create single Amazon CloudWatch metric alarms with multiple metric thresholds where possible.

Question # 94

An online retail company has more than 50 million active customers and receives more than 25,000 orders each day. The company collects purchase data for customers and stores this data in Amazon S3. Additional customer data is stored in Amazon RDS.

The company wants to make all the data available to various teams so that the teams can perform analytics. The solution must provide the ability to manage fine-grained permissions for the data and must minimize operational overhead.

Which solution will meet these requirements?

Migrate the purchase data to write directly to Amazon RDS. Use RDS access controls to limit access.

Schedule an AWS Lambda function to periodically copy data from Amazon RDS to Amazon S3. Create an AWS Glue crawler. Use Amazon Athena to query the data. Use S3 policies to limit access.

Create a data lake by using AWS Lake Formation. Create an AWS Glue JDBC connection to Amazon RDS. Register (he S3 bucket in Lake Formation. Use Lake Formation access controls to limit access.

Create an Amazon Redshift cluster. Schedule an AWS Lambda function to periodically copy data from Amazon S3 and Amazon RDS to Amazon Redshift. Use Amazon Redshift access controls to limit access.

Question # 95

A company is migrating its on-premises PostgreSQL database to Amazon Aurora PostgreSQL. The on-premises database must remain online and accessible during the migration. The Aurora database must remain synchronized with the on-premises database.

Which combination of actions must a solutions architect take to meet these requirements? (Choose two.)

Create an ongoing replication task.

Create a database backup of the on-premises database

Create an AWS Database Migration Service (AWS DMS) replication server

Convert the database schema by using the AWS Schema Conversion Tool (AWS SCT).

Create an Amazon EventBridge (Amazon CloudWatch Events) rule to monitor the database synchronization

Question # 96

A company runs workloads on AWS. The company needs to connect to a service from an external provider. The service is hosted in the provider's VPC. According to the companyâ€™s security team, the connectivity must be private and must be restricted to the target service. The connection must be initiated only from the companyâ€™s VPC.

Which solution will mast these requirements?

Create a VPC peering connection between the company's VPC and the provider's VPC. Update the route table to connect to the target service.

Ask the provider to create a virtual private gateway in its VPC. Use AWS PrivateLink to connect to the target service.

Create a NAT gateway in a public subnet of the company's VPC. Update the route table to connect to the target service.

Ask the provider to create a VPC endpoint for the target service. Use AWS PrivateLink to connect to the target service.
