A user is planning to use EBS for his DB requirement. The user already has an EC2 instance running in

the VPC private subnet.

How can the user attach the EBS volume to a running instance?

A. The user can create EBS in the same zone as the subnet of instance and attach that EBS to instance.

B. It is not possible to attach an EBS to an instance running in VPC until the instance is stopped.

C. The user can specify the same subnet while creating EBS and then attach it to a running instance.

D. The user must create EBS within the same VPC and then attach it to a running instance.

A hedge fund company is developing a new web application to handle trades. Traders around the world will use the application. The application will handle hundreds of thousands of transactions, especially during overlapping work hours between Europe and the United States.

According to the company's disaster recovery plan, the data that is generated must be replicated to a second AWS Region. Each transaction item will be less than 100 KB in size. The company wants to simplify the CI/CD pipeline as much as possible.

Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

A. Deploy the application in multiple Regions. Use Amazon Route 53 latency-based routing to route users

to the nearest deployment.

B. Provision an Amazon Aurora global database to persist data. Use Amazon ElastiCache to improve response time.

C. Provision an Amazon CloudFront domain with the website as an origin. Restrict access to geographies where the usage is expected.

D. Provision an Amazon DynamoDB global table. Use DynamoDB Accelerator (DAX) to improve response time.

E. Provision an Amazon Aurora multi-master cluster to persist data. Use Amazon ElastiCache to improve response time.

In DynamoDB, "The data is eventually consistent" means that__________.

A. a read request immediately after a write operation might not show the latest change.

B. a read request immediately after a write operation shows the latest change.

C. a write request immediately after a read operation might cause data loss.

D. a read request immediately after a write operation might cause data loss.

A company has an organization that has many AWS accounts in AWS Organizations. A solutions architect must improve how the company manages common security group rules for the AWS accounts in the organization.

The company has a common set of IP CIDR ranges in an allow list in each AWS account to allow access to and from the company's on-premises network. Developers within each account are responsible for adding new IP CIDR ranges to their security groups. The security team has its own AWS account. Currently, the security team notifies the owners of the other AWS accounts when changes are made to the allow list.

The solutions architect must design a solution that distributes the common set of CIDR ranges across all accounts.

Which solution meets these requirements with the LEAST amount of operational overhead?

A. Set up an Amazon Simple Notification Service (Amazon SNS) topic in the security team's AWS account. Deploy an AWS Lambda function in each AWS account. Configure the Lambda function to run every time an SNS topic receives a message. Configure the Lambda function to take an IP address as input and add it to a list of security groups in the account. Instruct the security team to distribute changes by publishing messages to its SNS topic.

B. Create new customer-managed prefix lists in each AWS account within the organization. Populate the prefix lists in each account with all internal CIDR ranges. Notify the owner of each AWS account to allow the new customer-managed prefix list IDs in their accounts in their security groups. Instruct the security team to share updates with each AWS account owner.

C. Create a new customer-managed prefix list in the security team's AWS account. Populate the customer-managed prefix list with all internal CIDR ranges. Share the customer-managed prefix list with the organization by using AWS Resource Access Manager. Notify the owner of each AWS account to allow the new customer-managed prefix list ID in their security groups.

D. Create an IAM role in each account in the organization. Grant permissions to update security groups. Deploy an AWS Lambda function in the security team's AWS account. Configure the Lambda function to take a list of internal IP addresses as input, assume a role in each organization account, and add the list of IP addresses to the security groups in each account.

A video streaming company recently launched a mobile app for video sharing. The app uploads various files to an Amazon S3 bucket in the us-east-1 Region. The files range in size from 1 GB to 10 GB.

Users who access the app from Australia have experienced uploads that take long periods of time. Sometimes the files fail to completely upload for these users. A solutions architect must improve the app's performance for these uploads.

Which solutions will meet these requirements? (Choose two.)

A. Enable S3 Transfer Acceleration on the S3 bucket. Configure the app to use the Transfer Acceleration endpoint for uploads.

B. Configure an S3 bucket in each Region to receive the uploads. Use S3 Cross-Region Replication to copy the files to the distribution S3 bucket.

C. Set up Amazon Route 53 with latency-based routing to route the uploads to the nearest S3 bucket Region.

D. Configure the app to break the video files into chunks. Use a multipart upload to transfer files to Amazon S3.

E. Modify the app to add random prefixes to the files before uploading.
