Question 1
Single choice

A company has created a multi-tier application for its ecommerce website. The website uses an Application Load Balancer that resides in the public subnets, a web tier in me public subnets, and a MySQL cluster hosted on Amazon EC2 instances in the private subnets.

Deploy a NAT gateway in the public subnets. Modify the private subnet route table to direct all internet-bound traffic to the NAT gateway.

C.

Configure an internet gateway and attach it to the VPC. Modify the private subnet route table to direct internet-bound traffic to the internet gateway.

D.

Configure a virtual private gateway and attach it to the VPC. Modify the private subnet route table to direct internet-bound traffic to the virtual private gateway.

Create a load balancer and associate two private subnets from the same Availability Zones as the private instances. Add the private instances to the load balancer.

A.

Create an Auto Scaling group and a load balancer in the disaster recovery Region.
Configure the DynamoDB table as a global table. Configure DNS failover to point to the new disaster
recovery Region's load balancer.

B.

Create an AWS CloudFormation template to create EC2 instances, load balancers, and DynamoDB tables to be launched when needed. Configure DNS failover to point to the new disaster recovery Region's load balancer.

C.

Create an AWS CloudFormation template to create EC2 instances and a load balancer to be launched when needed. Configure the DynamoDB table as a global table. Configure DNS failover to point to the
new disaster recovery Region's load balancer.

D.

Create an Auto Scaling group and load balancer in the disaster recovery Region.
Configure the DynamoDB table as a global table. Create an Amazon CloudWatch alarm to trigger an AWS Lambda function that updates Amazon Route 53 pointing to the disaster recovery load balancer.

Question 5
Multiple choice

A company wants to improve the availability and performance of its hybrid application. The application consists of a stateful TCP-based workload hosted on Amazon EC2 instances in different AWS Regions and a stateless UOP-based workload hosted on premises.

Which combination of actions should a solutions architect take to improve availability and performance? (Choose two.)

A.

Create an accelerator using AWS Global Accelerator. Add the load balancers as endpoints.

B.

Create an Amazon CloudFront distribution with an origin that uses Amazon Route 53 latency-based routing to route requests to the load balancers

C.

Configure two Application Load Balancers in each Region. The first will route to the EC2 endpoints and the second will route to the on-premises endpoints.

D.

Configure a Network Load Balancer in each Region to address the EC2 endpoints Configure a Network Load Balancer in each Region that routes to the on-premises endpoints

E.

Configure a Network Load Balancer in each Region to address the EC2 endpoints Configure an Application Load Balancer in each Region that routes to the on-premises endpoints

Question 6
Single choice

A company has developed a new video game as a web application. The application is in a three-tier architecture in a VPC with Amazon RDS for MySQL In the database layer Several players will compete concurrently online. The game's developers want to display a top-10 scoreboard in near-real time and offer the ability to stop and restore the game while preserving the current scores.

What should a solutions architect do to meet these requirements?

Set up an Amazon ElastiCache for Memcached cluster to cache the scores for the web application to display

B.

Set up an Amazon ElastiCache for Redis cluster to compute and cache the scores for the web application to display.

C.

Place an Amazon CloudFront distribution in front of the web application to cache the scoreboard m a section of the application.

D.

Create a read replica on Amazon RDS for MySQL to run queries to compute the scoreboard and serve the read traffic to the web application.

Question 7
Single choice

A solutions architect is creating a data processing job that runs once daily and can take up to 2 hours to complete If the job is interrupted, it has to restart from the beginning.

Question 8
Single choice

A solutions architect is designing an architecture to run a third-party database server. The database software Is memory intensive and has a CPU-based licensing model where the cost Increases with the number of vCPU cores within the operating system.
