Question 164

A company currently runs an on-premises stock trading application by using Microsoft Windows Server. The company wants to migrate the application to the AWS Cloud. The company needs to design a highly available solution that provides low-latency access to block storage across multiple Availability Zones. Which solution will meet these requirements with the LEAST implementation effort?

Options:

Configure a Windows Server cluster that spans two Availability Zones on Amazon EC2 instances. Install the application on both cluster nodes. Use Amazon FSx for Windows File Server as shared storage between the two cluster nodes.

Configure a Windows Server cluster that spans two Availability Zones on Amazon EC2 instances. Install the application on both cluster nodes Use Amazon Elastic Block Store (Amazon EBS) General Purpose SSD (gp3) volumes as storage attached to the EC2 instances. Set up application-level replication to sync data from one EBS volume in one Availability Zone to another EBS volume in the second Availability Zone.

Deploy the application on Amazon EC2 instances in two Availability Zones Configure one EC2 instance as active and the second EC2 instance in standby mode. Use an Amazon FSx for NetApp ONTAP Multi-AZ file system to access the data by using Internet Small Computer Systems Interface (iSCSI) protocol.

Deploy the application on Amazon EC2 instances in two Availability Zones. Configure one EC2 instance as active and the second EC2 instance in standby mode. Use Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD (io2) volumes as storage attached to the EC2 instances. Set up Amazon EBS level replication to sync data from one io2 volume in one Availability Zone to another io2 volume in the second Availability Zone.

Question 165

A company has an application that serves clients that are deployed in more than 20.000 retail storefront locations around the world. The application consists of backend web services that are exposed over HTTPS on port 443 The application is hosted on Amazon EC2 Instances behind an Application Load Balancer (ALB). The retail locations communicate with the web application over the public internet. The company allows each retail location to register the IP address that the retail location has been allocated by its local ISP.

The company's security team recommends to increase the security of the application endpoint by restricting access to only the IP addresses registered by the retail locations.

What should a solutions architect do to meet these requirements?

Options:

Associate an AWS WAF web ACL with the ALB Use IP rule sets on the ALB to filter traffic Update the IP addresses in the rule to Include the registered IP addresses

Deploy AWS Firewall Manager to manage the ALB. Configure firewall rules to restrict traffic to the ALB Modify the firewall rules to include the registered IP addresses.

Store the IP addresses in an Amazon DynamoDB table. Configure an AWS Lambda authorization function on the ALB to validate that incoming requests are from the registered IP addresses.

Configure the network ACL on the subnet that contains the public interface of the ALB Update the ingress rules on the network ACL with entries for each of the registered IP addresses.

Question 166

A company runs a payment processing system in the AWS Cloud Sometimes when a payment fails because of insufficient funds or technical issues, users attempt to resubmit the payment. Sometimes payment resubmissions invoke multiple payment messages for the same payment ID.

A solutions architect needs to ensure that the payment processing system receives payment messages that have the same payment ID sequentially, according to when the messages were generated. The processing system must process the messages in the order in which the messages are received. The solution must retain all payment messages for 10 days for analytics.

Which solutions will meet these requirements? (Select TWO.)

Options:

Write the payment messages to an Amazon DynamoDB table that uses the payment ID as the partition key.

Write the payment messages to an Amazon Kinesis data stream that uses the payment ID as the partition key.

Write the payment messages to an Amazon ElastiCache for Memcached cluster that uses the payment ID as the key

Write the payment messages to an Amazon Simple Queue Service (Amazon SQS) queue. Set the message attribute to use the payment ID.

Write the payment messages to an Amazon Simple Queue Service (Amazon SQS) FIFO queue Set the message group to use the payment ID.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Migrate the data to the S3 bucket. Use server-side encryption with Amazon S3 managed keys (SSE-S3). Use the built-in key rotation behavior of SSE-S3

encryption keys.

Create an AWS Key Management Service (AWS KMS) customer managed key Enable automatic key rotation Set the S3 bucket's default encryption behavior to use the customer managed KMS key. Migrate the data to the S3 bucket.

Create an AWS Key Management Service (AWS KMS) customer managed key Set the S3 bucket's default encryption behavior to use the customer managed KMS key. Migrate the data to the S3 bucket. Manually rotate the KMS key every year.

Use customer key material to encrypt the data Migrate the data to the S3 bucket. Create an AWS Key Management Service (AWS KMS) key without key material Import the customer key material into the KMS key. Enable automatic key rotation.
