Question: 1
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. The MySQL database needs to
retrieve product catalog and pricing information that is hosted on the internet by a third-party provider.
A solutions architect must devise a strategy that maximizes security without increasing operational
overhead.
What should the solutions architect do to meet these requirements?
A. Deploy a NAT instance in the VPC. Route all the internet-based traffic through the NAT instance.
B. 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.
Answer: C
Question: 2
A company has an application that is hosted on Amazon EC2 instances in two private subnets. A
solutions architect must make the application available on the public internet with the least amount of
N-y administrative effort.
What should the solutions architect recommend?
A. Create a load balancer and associate two public subnets from the same Availability Zones as the
private instances. Add the private instances to the load balancer.
B. 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.
C. Create an Amazon Machine Image (AMI) of the instances in the private subnet and restore In the
public subnet Create a load balancer and associate two public subnets from the same Availability Zones
as the public instances.
D. Create an Amazon Machine Image (AMI) of the instances in the private subnet and restore in the
public subnet. Create a load balancer and associate two private subnets from the same Availability
Zones as the public instances.
Answer: C
Question: 3
A company hosts its application in the AWS Cloud. The application runs on Amazon EC2 instances behind
an Elastic Load Balancer in an Auto Scaling group and with an Amazon DynamoDB table. The company
wants to ensure the application can be made available in another AWS Region with minimal downtime
What should a solutions architect do to meet these requirements with the LEAST amount of downtime?
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 Cloud Formation template to create EC2 instances, load balancers, and DynamoDB
tables to be executed when needed. Configure DNS failover to point to the new disaster recovery
Region's toad balancer.
C. Create an AWS CloudFormation template to create EC2 instances and a load balancer to be executed
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.
Answer: C
Question: 4
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?
(Select 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
Answer: AD
Question: 5
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?
A. 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.
Answer: D
