EXAM QUESTIONS
QUESTION 1
A Forex trading platform, which frequently processes and stores global financial data every minute, is
hosted in an on-premises data center and uses an Oracle database. Due to a recent cooling problem in
its data center, the company urgently needs to migrate its infrastructure to AWS to improve the
performance of its applications. As the Solutions Architect, the responsibility is to ensure that the
database is properly migrated and remains available in case of database server failure in the future.

, CORRECT ANSWER
Create an Oracle database in Amazon RDS with Multi-AZ deployments.
Migrate the Oracle database to AWS using the AWS Database Migration Service
RATIONALE: To ensure high availability of the Oracle database, Amazon RDS with Multi-AZ deployments is chosen
because it automatically replicates the database across multiple AZs, allowing for failover in case of database server
failure. The AWS Database Migration Service is then used to migrate the Oracle database to AWS, allowing the Forex
trading platform to take advantage of the scalability, reliability, and performance of the cloud while minimizing downtime
during the migration process.
QUESTION 2
A company has a cloud architecture composed of Linux and Windows Amazon EC2 instances that
process high volumes of financial data 24 hours a day, 7 days a week. To ensure high availability of the
systems, the Solutions Architect must create a solution that enables monitoring of memory and disk
utilization metrics for all instances.
Which of the following is the most suitable monitoring solution to implement?
CORRECT ANSWER
Install the Amazon CloudWatch agent to all the EC2 instances that gather the memory and disk utilization
data. View the custom metrics in the CloudWatch console.
RATIONALE: The Amazon CloudWatch agent is the most suitable monitoring solution to implement because it allows the
Solutions Architect to collect memory and disk utilization metrics directly from the EC2 instances, providing real-time data
and ensuring high availability of the systems. This approach enables the architect to monitor and analyze the
performance of all instances in real-time, making it an ideal solution for a 24/7 high-volume data processing environment.
QUESTION 3
A government entity is conducting a population and housing census in the city. Each household
information uploaded on their online portal is stored in encrypted files in Amazon S3. The government
assigned its Solutions Architect to set compliance policies that verify data containing personally
identifiable information (PII) in a manner that meets their compliance standards. They should also be
alerted if there are potential policy violations with the privacy of their S3 buckets.
Which of the following should the Architect implement to satisfy this requirement?
CORRECT ANSWER
Set up and configure Amazon Macie to monitor their Amazon S3 data.
RATIONALE: The Architect should implement Amazon Macie to monitor S3 data because it enables the government to
identify and classify sensitive data, including PII, and detect potential compliance issues in real-time, ensuring their
census data meets the required standards. By leveraging Macie's automated data discovery and analytics capabilities, the
government can effectively monitor and protect their sensitive data, thereby satisfying their compliance requirement.
QUESTION 4
A popular social media website uses a Amazon CloudFront web distribution to serve static content to
millions of users around the globe. Recently, the website has received a number of complaints about
Trusted by thousands of students and professionals worldwide Page 2 of 28
, long login times. Additionally, there are instances where users encounter HTTP 504 errors. The
manager has instructed the team to significantly reduce login time and further optimize the system.
CORRECT ANSWER
Customize the content that the CloudFront web distribution delivers to your users using Lambda@Edge,
which allows your AWS Lambda functions to execute the authentication process in AWS locations closer to
the users.
Implement an origin failover by creating an origin group that includes two origins. Assign one as the
primary origin and the other as secondary, which enables CloudFront to automatically switch to if the
primary origin encounters specific HTTP status code failure responses.
RATIONALE: To address the long login times and HTTP 504 errors, the team can use Lambda@Edge to execute
authentication processes closer to users, reducing latency and improving performance. By implementing an origin failover
with a primary and secondary origin, CloudFront can automatically switch to a working origin if the primary one
encounters errors, ensuring a more reliable and efficient user experience.
QUESTION 5
A company has a web application that uses Internet Information Services (IIS) for Windows Server. A
file share is used to store the application data on the network-attached storage of the company's on-
premises data center. To achieve a highly available system, the company plans to migrate the
application and file share to AWS.
Which of the following can be used to fulfill this requirement?
CORRECT ANSWER
Migrate the existing file share configuration to Amazon FSx for Windows File Server.
RATIONALE: Amazon FSx for Windows File Server provides a highly available and durable file share solution, which aligns
with the company's requirement for a highly available system. By migrating the existing file share configuration to
Amazon FSx for Windows File Server, the company can maintain consistency in file share functionality while taking
advantage of AWS's scalability and reliability features.
QUESTION 6
A content management system (CMS) is hosted on a fleet of auto-scaled, On-Demand Amazon EC2
instances that use Amazon Aurora as its database. Currently, the system stores the file documents that
users upload in one of the attached Amazon EBS volumes. The system's performance has been
observed to be slow, and the manager has instructed the team to improve the architecture.
In this scenario, which solution should be implemented to achieve a scalable, highly available, POSIX-
compliant shared file system?
CORRECT ANSWER
Use Amazon EFS to provide a shared file system for concurrent access to data
