Question #:1
A company is setting up a new website for online sales. The company will have a web
tier and a database tier. The web tier consists of load-balanced, auto-scaled Amazon EC2
instances in multiple Availability Zones (AZs). The database tier is an Amazon RDS Multi-AZ
deployment. The EC2 instances must connect securely to the database.
How should the resources be launched?
A.  EC2 instances: public subnet
RDS database instances: public subnet
Load balancer: public subnet
B.  EC2 instances: public subnet
RDS database instances: private subnet
Load balancer: private subnet
C.  EC2 instances: private subnet
RDS database instances: public subnet
Load balancer: public subnet
D.  EC2 instances: private subnet
RDS database instances: private subnet
Load balancer: public subnet
Answer: D
Question #:2
As part of a migration strategy, a Solutions Architect needs to analyze workloads that can be optimized for
performance and cost. The Solutions Architect has identified a stateless application that serves static content as
a potential candidate to move to the cloud.

The Solutions Architect has the flexibility to choose an identity solution between Facebook, Twitter, and
Amazon.
Which AWS solution offers flexibility and ease of use, and the LEAST operational overhead for this
migration?
A.  Use AWS Identity and Access Management (1AM) for managing identities, and migrate the application
to run on Amazon S3, Amazon API Gateway, and AWS Lambda.
B.  Use a third-party solution for managing identities, and migrate the application to run on Amazon S3,
EC2 Spot Instances, and Amazon EC2.
C.  Use Amazon Cognito for managing identities, and migrate the application to run on Amazon S3,
Amazon API Gateway, and AWS Lambda.
D.  Use Amazon Cognito for managing identities, and migrate the application to run on Amazon S3, EC2
Spot Instances, and Amazon EC2..
Answer: B
Question #:3
A Solutions Architect has a multi-layer application running in Amazon VPC. The
application has an ELB Classic Load Balancer as the front end in a public subnet, and an
Amazon EC2-based reverse proxy that performs content-based routing to two backend
Amazon EC2 instances hosted in a private subnet. The Architect sees tremendous traffic
growth and is concerned that the reverse proxy and current backend set up will be
insufficient.
Which actions should the Architect take to achieve a cost-effective solution that ensures the
application automatically scales to meet traffic demand? (Select two.)
A.  Replace the Amazon EC2 reverse proxy with an ELB internal Classic Load Balancer.
B.  Add Auto Scaling to the Amazon EC2 backend fleet.
C.  Add Auto Scaling to the Amazon EC2 reverse proxy layer.
D.  Use t2 burstable instance types for the backend fleet.
E.  Replace both the frontend and reverse proxy layers with an ELB Application Load
Balancer.

Question #:4
A Solutions Architect is designing a solution for a media company that will stream large
amounts of data from an Amazon EC2 instance. The data streams are typically large and
sequential, and must be able to support up to 500 MB/s.
Which storage type will meet the performance requirements of this application?
A.  EBS Provisioned IOPS SSD
B.  EBS General Purpose SSD
C.  EBS Cold HDD
D.  EBS Throughput Optimized HDD
.
Answer: D
Question #:5
A customer needs to capture all client connection information from their load balancer every five minutes. The
company wants to use data for analyzing traffic patterns and troubleshooting their applications. Which of the
following options meets the customer requirements?
A.  Enable access logs on the load balancer
B.  Enable AWS CloudTrail for the load balancer
C.  Enable Amazon CloudWatch metrics on the load balancer
D.  Install the Amazon CloudWatch Logs agent on the load balancer
Answer: A
Question #:6
A company plans to migrate a website to AWS to use a serverless architecture. The website contains both
static and dynamic content and is accessed by users across the world.

The website should maintain sessions for returning users to improve the user experience.
Which service should a Solutions Architect use for a cost-efficient solution with the LOWEST latency?
A.  Amazon S3, AWS Lambda, Amazon API Gateway, and Amazon DynamoDB
B.  Amazon CloudFront, AWS Lambda, API Gateway, and Amazon RDS
C.  Amazon CloudFront, Elastic Load Balancing, Amazon EC2, and Amazon RDS
D.  Amazon S3, Amazon CloudFront, AWS Lambda, Amazon API Gateway, and Amazon DynamoDB.
Answer: D
Question #:7
A company hosts a website on premises. The website has a mix of static and dynamic content, but users
experience latency when loading static files.
Which AWS service can help reduce latency?
A.  Amazon CloudFront with on-premises servers as the origin
B.  ELB Application Load Balancer
C.  Amazon Route 53 latency-based routing
D.  Amazon EFS to store and server static files
Answer: A
Question #:8
A solutions architect needs to convert potential single points of failure to a highly-available configuration. The
currently architecture contains amazon EC2 instances with databases running in one availability zone.
Web-tier resources have not been given public addresses, but still require internet access.
Which solution should the architect use to maintain high availability?
A.  Use ELB Classic Load Balancer with the web tier Deploy EC2 instances in two Availability Zones and
enable Multi-AZ RDS Deploy a NAT gateway in one Availability Zone
B.  Use ELB Classic Load Balancer with the web tier Deploy EC2 instances in two Availability Zones and
enable Multi-AZ RDS Deploy NAT gateways in both Availability Zones
C.  Use ELB Classic Load Balancer with the database tier Deploy Amazon EC2 instances in two
Availability Zones and enable Multi-AZ RDS Deploy NAT gateways in both Availability Zones

Zones and enable Multi-AZ RDS Deploy a NAT gateway in one Availability Zone
Answer: C
Question #:9
A workload consists of downloading an image from an Amazon S3 bucket, processing the image, and moving
it to another Amazon S3 bucket. An Amazon EC2 instance runs a
scheduled task every hour to perform the operation.
How should a Solutions Architect redesign the process so that it is highly available?
A.  Change the Amazon EC2 instance to compute optimized.
B.  Launch a second Amazon EC2 instance to monitor the health of the first.
C.  Trigger a Lambda function when a new object is uploaded.
D.  Initially copy the images to an attached Amazon EBS volume.
Answer: A
Question #:10
A web application running on Amazon EC2 instances writes data synchronously to an Amazon DynamoDB
table configured for 60 write capacity units. During normal operation
the application writes 50 KB/s to the tale, but can scale up to 500 KB/ s during peak hours.
The application is currently throttling errors from the DynamoDB table during peak hours.
What is the MOST cost-efficient change to support the increased traffic with minimal changes to the
application?
A.  Use Amazon SQS to manage the write operations to the DynamoDB table.
B.  Change DynamoDB table configuration to 600 write capacity units.
C.  Increase the number of Amazon EC2 instances to support the traffic.
D.  Configure Amazon DynamoDB Auto Scaling to handle the extra demand.
