Latest Amazon SAA-C02 Exam Practice Questions and Answers
QUESTION 1
A company has migrated an on-premises Oracle database to an Amazon RDS for Oracle Multi-AZ DB instance in the useast-l Region. A solutions architect is designing a disaster recovery strategy to have the database provisioned in the uswest-2 Region in case the database becomes unavailable in the us-east-1 Region. The design must ensure the database is provisioned in the us-west-2 Region in a maximum of 2 hours, with a data loss window of no more than 3
hours.
How can these requirements be met?
A. Edit the DB instance and create a read replica in us-west-2. Promote the read replica to master In us-west-2 in case
the disaster recovery environment needs to be activated.
B. Select the multi-Region option to provision a standby instance in us-west-2. The standby Instance will be
automatically promoted to master In us-west-2 in case the disaster recovery environment needs to be created.
C. Take automated snapshots of the database instance and copy them to us-west-2 every 3 hours. Restore the latest
snapshot to provision another database instance in us-west-2 in case of the disaster recovery environment needs to be
activated.
D. Create a Multimaster read/write instances across multiple AWS Regions Select VPCs in us-east-1 and us-west-2 lo
make that deployment. Keep the master read/write instance in us-west-2 available to avoid having to activate a disaster
recovery environment.
Correct Answer: A

QUESTION 7
A monolithic application was recently migrated to AWS and is now running on a single Amazon EC2 instance. Due to
application limitations, it is not possible to use automatic scaling to scale out the application. The chief technology officer
(CTO) wants an automated solution to restore the EC2 instance in the unlikely event the underlying hardware fails.
What would allow for automatic recovery of the EC2 instance as quickly as possible?
A. Configure an Amazon CloudWatch alarm that triggers the recovery of the EC2 instance if it becomes impaired.
B. Configure an Amazon CloudWatch alarm to trigger an SNS message that alerts the CTO when the EC2 instance is
impaired.
C. Configure AWS CloudTrail to monitor the health of the EC2 instance, and if it becomes impaired, triggered instance
recovery.
D. Configure an Amazon EventBridge event to trigger an AWS Lambda function once an hour that checks the health of
the EC2 instance and triggers instance recovery if the EC2 instance is unhealthy.
Correct Answer: C
QUESTION 8
A web application runs on Amazon EC2 instances behind an Application Load Balancer. The application allows users to
create custom reports of historical weather data. Generating a report can take up to 5 minutes. These long-running
requests use many of the available incoming connections, making the system unresponsive to other users.
How can a solutions architect make the system more responsive?
A. Use Amazon SQS with AWS Lambda to generate reports.
B. Increase the idle timeout on the Application Load Balancer to 5 minutes.
C. Update the client-side application code to increase its request timeout to 5 minutes.
D. Publish the reports to Amazon S3 and use Amazon CloudFront for downloading it to the user.
Correct Answer: A
QUESTION 9
A solutions architect is designing a customer-facing application. The application is expected to have a variable amount

a solutions architect do to meet these requirements?
A. Redesign the application to use Amazon CloudFront.
B. Redesign the application to use AWS Elastic Beanstalk.
C. Redesign the application to use a Network Load Balancer.
D. Redesign the application to use Amazon S3 static website hosting.
Correct Answer: A
What Is Amazon CloudFront?
Amazon CloudFront is a web service that speeds up the distribution of your static and dynamic web content, such as .html,
.css, .js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers
called edge locations. When a user requests content that you\\’re serving with CloudFront, the user is routed to the edge
location that provides the lowest latency (time delay), so that content is delivered with the best possible performance.
If the content is already in the edge location with the lowest latency, CloudFront delivers it immediately.
If the content is not in that edge location, CloudFront retrieves it from an origin that you\ \’s defined – such as an
Amazon S3 bucket, a MediaPackage channel, or an HTTP server (for example, a web server) that you have identified
as the
source for the definitive version of your content.
As an example, suppose that you\\’re serving an image from a traditional web server, not from CloudFront. For example,
you might serve an image, sunsetphoto.png, using the URL http://example.com/sunsetphoto.png.
Your users can easily navigate to this URL and see the image. But they probably don\\’t know that their request was
routed from one network to another – through the complex collection of interconnected networks that comprise the
internet –
until the image was found.
CloudFront speeds up the distribution of your content by routing each user request through the AWS backbone network
to the edge location that can best serve your content. Typically, this is a CloudFront edge server that provides the
fastest
delivery to the viewer. Using the AWS network dramatically reduces the number of networks that your users\\’ requests
must pass through, which improves performance. Users get lower latency – the time it takes to load the first byte of the
file
– and higher data transfer rates.
You also get increased reliability and availability because copies of your files (also known as objects) are now held (or
cached) in multiple edge locations around the world.
