A Solutions Architect is creating a design for a multi-tiered serverless application. Which two services form the application facing services from the AWS serverless infrastructure? (Select TWO.)

An application that you will be deploying in your VPC requires 14 EC2 instances that must be placed on distinct underlying hardware to reduce the impact of the failure of a hardware node. The instances will use varying instance types. What configuration will cater to these requirements taking cost-effectiveness into account?

A Solutions Architect is designing a web application that runs on Amazon EC2 instances behind an Elastic Load Balancer. All data in transit must be encrypted.

Which solution options meet the encryption requirement? (Select TWO.)

A large media site has multiple applications running on Amazon ECS. A Solutions Architect needs to use content metadata to route traffic to specific services.

What is the MOST efficient method to fulfil this requirement?

You have been asked to deploy a new High-Performance Computing (HPC) cluster. You need to create a design for the EC2 instances that ensures close proximity, low latency and high network throughput.

Which AWS features will help you to achieve this requirement whilst considering cost? (Select TWO.)

A solutions architect is creating a system that will run analytics on financial data for 4 hours a night, 5 days a week. The analysis is expected to run for the same duration and cannot be interrupted once it is started. The system will be required for a minimum of 1 year.

Which type of Amazon EC2 instances should be used to reduce the cost of the system?

A company’s application is running on Amazon EC2 instances in a single Region. In the event of a disaster, a solutions architect needs to ensure that the resources can also be deployed to a second Region.

Which combination of actions should the solutions architect take to accomplish this? (Select TWO.)

A solutions architect is finalizing the architecture for a distributed database that will run across multiple Amazon EC2 instances. Data will be replicated across all instances so the loss of an instance will not cause loss of data. The database requires block storage with low latency and throughput that supports up to several million transactions per second per server.

Which storage solution should the solutions architect use?

A new application will be launched on an Amazon EC2 instance with an Elastic Block Store (EBS) volume. A solutions architect needs to determine the most cost-effective storage option. The application will have infrequent usage, with peaks of traffic for a couple of hours in the morning and evening. Disk I/O is variable with peaks of up to 3,000 IOPS.

Which solution should the solutions architect recommend?

A company runs a financial application using an Amazon EC2 Auto Scaling group behind an Application Load Balancer (ALB). When running month-end reports on a specific day and time each month the application becomes unacceptably slow. Amazon CloudWatch metrics show the CPU utilization hitting 100%.

What should a solutions architect recommend to ensure the application is able to handle the workload and avoid downtime?
