A company has a data ingestion workflow that consists the following:
An Amazon Simple Notification Service (Amazon SNS) topic for notifications about new data deliveries
An AWS Lambda function to process the data and record metadata
The company observes that the ingestion workflow fails occasionally because of network connectivity issues. When such a failure occurs, the Lambda function does not ingest the corresponding data unless the company manually reruns the job.
Which combination of actions should a solutions architect take to ensure that the Lambda function ingests all data in the future? (Select TWO.)

1. A. Configure the Lambda function In multiple Availability Zones.
2. B. Create an Amazon Simple Queue Service (Amazon SQS) queue, and subscribe It to me SNS topic.
3. C. Increase the CPU and memory that are allocated to the Lambda function.
4. D. Increase provisioned throughput for the Lambda function.
5. E. Modify the Lambda function to read from an Amazon Simple Queue Service (Amazon SQS) queue

Correct Answer: BE

A company recently migrated to AWS and wants to implement a solution to protect the traffic that flows in and out of the production VPC. The company had an inspection server in its on-premises data center. The inspection server performed specific operations such as traffic flow inspection and traffic filtering. The company wants to have the same functionalities in the AWS Cloud.
Which solution will meet these requirements?

1. A. Use Amazon GuardDuty for traffic inspection and traffic filtering in the production VPC
2. B. Use Traffic Mirroring to mirror traffic from the production VPC for traffic inspection and filtering.
3. C. Use AWS Network Firewall to create the required rules for traffic inspection and traffic filtering for the production VPC.
4. D. Use AWS Firewall Manager to create the required rules for traffic inspection and traffic filtering for the production VPC.

Correct Answer: C
AWS Network Firewall supports both inspection and filtering as required

A solutions architect is designing a VPC with public and private subnets. The VPC and subnets use IPv4 CIDR blocks. There is one public subnet and one private subnet in each of three Availability Zones (AZs) for high availability. An internet gateway is used to provide internet access for the public subnets. The private subnets require access to the internet to allow Amazon EC2 instances to download software updates.
What should the solutions architect do to enable Internet access for the private subnets?

1. A. Create three NAT gateways, one for each public subnet in each A
2. B. Create a private route table for each AZ that forwards non-VPC traffic to the NAT gateway in its AZ.
3. C. Create three NAT instances, one for each private subnet in each A
4. D. Create a private route table for each AZ that forwards non-VPC traffic to the NAT instance in its AZ.
5. E. Create a second internet gateway on one of the private subnet
6. F. Update the route table for the private subnets that forward non-VPC traffic to the private internet gateway.
7. G. Create an egress-only internet gateway on one of the public subnet
8. H. Update the route table for the private subnets that forward non-VPC traffic to the egress- only internet gateway.

A company wants to migrate an Oracle database to AWS. The database consists of a single table that contains millions of geographic information systems (GIS) images that are high resolution and are identified by a geographic code.
When a natural disaster occurs tens of thousands of images get updated every few minutes. Each geographic code has a single image or row that is associated with it. The company wants a solution that is highly available and scalable during such events
Which solution meets these requirements MOST cost-effectively?

1. A. Store the images and geographic codes in a database table Use Oracle running on an Amazon RDS Multi-AZ DB instance
2. B. Store the images in Amazon S3 buckets Use Amazon DynamoDB with the geographic code as the key and the image S3 URL as the value
3. C. Store the images and geographic codes in an Amazon DynamoDB table Configure DynamoDB Accelerator (DAX) during times of high load
4. D. Store the images in Amazon S3 buckets Store geographic codes and image S3 URLs in a database table Use Oracle running on an Amazon RDS Multi-AZ DB instance.

Correct Answer: A

A data analytics company wants to migrate its batch processing system to AWS. The company receives thousands of small data files periodically during the day through FTP. A on-premises batch job processes the data files overnight. However, the batch job takes hours to finish running.
The company wants the AWS solution to process incoming data files are possible with minimal changes to the FTP clients that send the files. The solution must delete the incoming data files the files have been processed successfully. Processing for each file needs to take 3-8 minutes.
Which solution will meet these requirements in the MOST operationally efficient way?

1. A. Use an Amazon EC2 instance that runs an FTP server to store incoming files as objects in Amazon S3 Glacier Flexible Retrieva
2. B. Configure a job queue in AWS Batc
3. C. Use Amazon EventBridge rules to invoke the job to process the objects nightly from S3 Glacier Flexible Retrieva
4. D. Delete the objects after the job has processed the objects.
5. E. Use an Amazon EC2 instance that runs an FTP server to store incoming files on an Amazon Elastic Block Store (Amazon EBS) volum
6. F. Configure a job queue in AWS Batc
7. G. Use Amazon EventBridge rules to invoke the process the files nightly from the EBS volum
8. H. Delete the files after the job has processed the files.
9. I. Use AWS Transfer Family to create an FTP server to store incoming files on an Amazon Elastic Block Store (Amazon EBS) volum
10. J. Configure a job queue in AWS Batc
11. K. Use an Amazon S3 event notification when each files arrives to invoke the job in AWS Batc
12. L. Delete the files after the job has processed the files.
13. M. Use AWS Transfer Family to create an FTP server to store incoming files in Amazon S3 Standard.Create an AWS Lambda function to process the files and to delete the files after they are proessed.yse an S3 event notification to invoke the lambda function when the fils arrive

Correct Answer: C
