4. A company has two VPCs named Management and Production. The Management VPC uses VPNs through a customer gateway to connect to a single device in the data center. The Production VPC uses a virtual private gateway with two attached AWS Direct Connect connections. The Management and Production VPCs both use a single VPC peering connection to allow communication between the applications. What should a solutions architect do to mitigate any single point of failure in this architecture?
Add a set of VPNs between the Management and Production VPCs. Add a second virtual private gateway and attach it to the Management VPC. Add a second set of VPNs to the Management VPC from a second customer gateway device. Add a second VPC peering connection between the Management VPC and the Production VPC.
5. A solutions architect needs to host a high performance computing (HPC) workload in the AWS Cloud. The workload will run on hundreds of Amazon EC2 instances and will require parallel access to a shared file system to enable distributed processing of large datasets. Datasets will be accessed across multiple instances simultaneously. The workload requires access latency within 1 ms. After processing has completed, engineers will need access to the dataset for manual postprocessing. Which solution will meet these requirements?

Which solution meets these requirements?
Use server-side encryption to encrypt the data that is being uploaded to the S3 buckets. Create bucket policies that require the use of server-side encryption with S3 managed encryption keys (SSE-S3) for S3 uploads. Use client-side encryption to encrypt the data that is being uploaded to the S3 buckets. Enable the security option to encrypt the S3 buckets through the use of a default AWS Key Management Service (AWS KMS) key.

What is the MOST operationally efficient solution that meets these requirements?
Create an Amazon Simple Queue Service (Amazon SQS) standard queue to ingest the alerts, and set the message retention period to 14 days. Configure consumers to poll the SQS queue, check the age of the message, and analyze the message data as needed. If the message is 14 days old, the consumer should copy the message to an Amazon S3 bucket and delete the message from the SQS queue. Launch Amazon EC2 instances across two Availability Zones and place them behind an Elastic Load Balancer to ingest the alerts. Create a script on the EC2 instances that will store the alerts in an Amazon S3 bucket. Set up an S3 Lifecycle configuration to transition data to Amazon S3 Glacier after 14 days. Create an Amazon Kinesis Data Firehose delivery stream to ingest the alerts. Configure the Kinesis Data Firehose stream to deliver the alerts to an Amazon Elasticsearch Service (Amazon ES) cluster.

All company resources are tagged with a tag name of ?€application?€ and a value that corresponds to each application. A solutions architect must provide the quickest solution for identifying all of the tagged components. Which solution meets these requirements?
Use the AWS CLI to query each service across all Regions to report the tagged components. Run a query with the AWS Resource Groups Tag Editor to report on the resources globally with the application tag. Run a query in Amazon CloudWatch Logs Insights to report on the components with the application tag. Use AWS CloudTrail to generate a list of resources with the application tag.
30. A company is using an Amazon S3 bucket to store data uploaded by different departments from multiple locations. During an AWS Well-Architected review, the financial manager notices that 10 TB of S3 Standard storage data has been charged each month. However, in the AWS Management Console for Amazon S3, using the command to select all files and folders shows a total size of 5 TB. What are the possible causes for this difference? (Choose two.)
The S3 bucker has AWS Key Management Service (AWS KMS) enabled. There are incomplete S3 multipart uploads. Some files are stored with deduplication. The S3 bucket has versioning enabled. The S3 bucket has Intelligent-Tiering enabled.
