If you decided to create service accounts (that is, accounts used for programmatic access by applications running
outside of the AWS environment) and generate access keys for them, you should create a dedicated service account for
each use case. This will allow you to restrict the associated policy to only the permissions needed for the particular use
case, limiting the blast radius if the credentials are compromised. For example, if a monitoring tool and a release
management tool both require access to your AWS environment, create two separate service accounts with two
separate policies that define the minimum set of permissions for each tool.

Which of the following can a customer use to enable single sign-on (SSO) to the AWS Console?

When architecting cloud applications, which of the following are a key design principle?
A. Use the largest instance possible
B. Provision capacity for peak load
C. Use the Scrum development process
D. Implement elasticity
Correct Answer: B
Cloud services main proposition is to provide elasticity through horizontal scaling. It\\’s already there. As for using
largest instance possible, it is not a design principle that helps cloud applications in anyway. Scrum development
process is not related to architecting. Therefore, a key principle is to provision your application for on-demand capacity.
Peak loads is something that cloud applications experience everyday. Peak load management should be a necessary
part of cloud application design principle.

Amazon AWS Certified Associate SAA-C01 exam effective practice questions

A company is launching a new static website on Amazon S3 and Amazon CloudFront. The company wants to ensure
that all web requests go through only CloudFront.
How can a Solutions Architect meet this requirement?
A. Configure the S3 bucket policy to allow only CloudFront IP addresses to read objects.
B. Create IAM users in a group that has read access to the S3 bucket. Configure CloudFront to pass credentials to the
S3 bucket.
C. Create a CloudFront origin access identity (OAI), then update the S3 bucket policy to allow the OAI read access.
D. Convert the S3 bucket to an EC2 instance, then give CloudFront access to the instance by using security groups.
Correct Answer: C
To allow access to your Amazon S3 bucket only from a CloudFront distribution, first add an origin access identity (OAI)
to your distribution. Then, review your bucket policy and Amazon S3 access control list (ACL) to be sure that:
Only the OAI can access your bucket.
CloudFront can access the bucket on behalf of requesters.
Users can\\’t access the objects in other ways, such as by using Amazon S3 URLs.

A Solutions Architect is designing an application in AWS. The Architect must not expose the application or database tier
over the Internet for security reasons. The application must be low-cost and have a scalable front end. The databases
and application tier must have only one-way Internet access to download software and patch updates.
Which solution helps to meet these requirements?
A. Use a NAT Gateway as the front end for the application tier and to enable the private resources to have Internet
B. Use an Amazon EC2-based proxy server as the front end for the application tier, and a NAT Gateway to allow
Internet access for private resources.
C. Use an ELB Classic Load Balancer as the front end for the application tier, and an Amazon EC2 proxy server to allow
Internet access for private resources.
D. Use an ELB Classic Load Balancer as the front end for the application tier, and a NAT Gateway to allow Internet
access for private resources.
Correct Answer: D

A customer has an application that is used by enterprise customers outside of AWS. Some of these customers use
legacy firewalls that cannot whitelist by DNS name, but whitelist based only on IP address. The application is currently
deployed in two Availability Zones, with one EC2 instance in each that has Elastic IP addresses. The customer wants to
whitelist only two IP addresses, but the two existing EC2 instances cannot sustain the amount of traffic.
What can a Solutions Architect do to support the customer and allow for more capacity? (Choose two.)
A. Create a Network Load Balancer with an interface in each subnet, and assign a static IP address to each subnet.
B. Create additional EC2 instances and put them on standby. Remap an Elastic IP address to a standby instance in the
event of a failure.
C. Use Amazon Route 53 with a weighted, round-robin routing policy across the Elastic IP addresses to resolve one at a
D. Add additional EC2 instances with Elastic IP addresses, and register them with Amazon Route 53
E. Switch the two existing EC2 instances for an Auto Scaling group, and register them with the Network Load Balancer.
Correct Answer: BC

An application provides a feature that allows users to securely download private and personal files. The web server is
currently overwhelmed with serving files for download. A Solutions Architect must find a more effective solution to
reduce web server load and costs, and must allow users to download only their own files.
Which solution meets all requirements?
A. Store the files securely on Amazon S3 and have the application generate an Amazon S3 pre-signed URL for the user
to download.
B. Store the files in an encrypted Amazon EBS volume, and use a separate set of servers to serve the downloads.
C. Have the application encrypt the files and store them in the local Amazon EC2 Instance Store prior to serving them
up for download.
D. Create an Amazon CloudFront distribution to distribute and cache the files.
Correct Answer: A
Pre-signed S3 URLs are useful whenever you want to easily provide temporary access to a protected asset. There are
two common use cases when you may want to use pre-signed S3 URLs:
Simple, occasional sharing of private files.
Frequent, programmatic access to view or upload a file in an application.

A company has a legal requirement to store point-in-time copies of its Amazon RDS PostGreSQL database instance in facilities that are at least 200 miles apart.
Use of which of the following provides the easiest way to comply with this requirement?
A. Cross-region read replica
B. Multiple Availability Zone snapshot copy
C. Multiple Availability Zone read replica
D. Cross-region snapshot copy
Correct Answer: D
