Question 152

A solutions architect needs to design a solution for a high performance computing (HPC) workload. The solution must include multiple Amazon EC2 instances. Each EC2 instance requires 10 Gbps of bandwidth individually for single-flow traffic. The EC2 instances require an aggregate throughput of 100 Gbps of bandwidth across all EC2 instances. Communication between the EC2 instances must have low latency.

Which solution will meet these requirements?

Options:

Place the EC2 instances in a single subnet of a VPC. Configure a cluster placement group. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.

Place the EC2 instances in multiple subnets in a single VPC. Configure a spread placement group. Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.

Place the EC2 instances in multiple VPCs. Use AWS Transit Gateway to route traffic between the VPCs. Ensure that the latest Elastic Fabric Adapter (EFA) drivers are installed on the EC2 instances with a supported operating system.

Place the EC2 instances in multiple subnets across multiple Availability Zones. Configure a cluster placement group. Ensure that the EC2 instances support Elastic Network Adapters (ENAs) and that the drivers are updated on each instance operating system.

Question 153

A media company runs an application on multiple Amazon EC2 instances that requires high storage input/output operations per second (IOPS).

To achieve the necessary performance, a solutions architect wants to stripe multiple Amazon EBS volumes together and attach the volumes to EC2 instances. The solutions architect wants to receive a notification when IOPS are over-provisioned.

Which solution will meet these requirements?

Options:

Configure auto scaling for the EBS volumes to automatically increase or decrease IOPS based on the EC2 instance CPU utilization metric.

Deploy the application on an EC2 instance type that supports the highest possible IOPS.

Create a custom AWS Config rule to monitor the provisioned IOPS for the EBS volumes that are attached to the EC2 instances and to send notifications.

Adjust the IOPS of each EBS volume daily based on Amazon CloudWatch metrics for IOPS utilization.

Absolutely. It's a great way to increase your chances of success.

Alaya

Best Dumps among other dumps providers. I like it so much because of their authenticity.

Kaiden Mar 9, 2026

That's great. I've used other dump providers in the past and they were often outdated or had incorrect information. This time I will try it.

Do anyone guide my how these dumps would be helpful for new students like me?

Haris Mar 23, 2026

Absolutely! They are highly recommended for anyone looking to pass their certification exam. The dumps are easy to understand and follow, making it easier for you to study and retain the information.

Anaya

I found so many of the same questions on the real exam that I had already seen in the Cramkey Dumps. Thank you so much for making exam so easy for me. I passed it successfully!!!

Nina Mar 25, 2026

It's true! I felt so much more confident going into the exam because I had already seen and understood the questions.

Question 154

A company is setting up a development environment on AWS for a team of developers. The team needs to access multiple Amazon S3 buckets to store project data. The team also needs to use Amazon EC2 to run development instances.

The company needs to ensure that the developers have access only to specific Amazon S3 buckets and EC2 instances. Access permissions must be assigned according to each developer ' s role on the team. The company wants to minimize the use of permanent credentials and to ensure access is securely managed according to the principle of least privilege.

Which solution will meet these requirements?

Options:

Create IAM roles that have administrative-level permissions for Amazon S3 and Amazon EC2. Require developers to sign in by using Amazon Cognito to access Amazon S3 and Amazon EC2.

Create IAM roles that have fine-grained permissions for Amazon S3 and Amazon EC2. Configure AWS IAM Identity Center to manage credentials for the developers.

Create IAM users that have programmatic access to Amazon S3 and Amazon EC2. Generate individual access keys for each developer to access Amazon S3 and Amazon EC2.

Create a VPC endpoint for Amazon S3. Require developers to access Amazon EC2 instances and Amazon S3 buckets through a bastion host.

Question 155

A company needs to run its external website on Amazon EC2 instances and on-premises virtualized servers. The AWS environment has a 1 GB AWS Direct Connect connection to the data center. The application has IP addresses that will not change. The on-premises and AWS servers are able to restart themselves while maintaining the same IP address if a failure occurs. Some website users have to add their vendors to an allow list, so the solution must have a fixed IP address. The company needs a solution with the lowest operational overhead to handle this split traffic.

What should a solutions architect do to meet these requirements?

Options:

Deploy an Amazon Route 53 Resolver with rules pointing to the on-premises and AWS IP addresses.

Deploy a Network Load Balancer on AWS. Create target groups for the on-premises and AWS IP addresses.

Deploy an Application Load Balancer on AWS. Register the on-premises and AWS IP addresses with the target group.

Deploy Amazon API Gateway to direct traffic to the on-premises and AWS IP addresses based on the header of the request.
