Questions and Answers: A Guide to the AWS Certified Solutions Architect - Associate SAA-C03 Exam | Part 1


#1. In an IT company, a scaling policy is used to keep a constant count of Amazon EC2 instances across various Availability Zones to match application demands. A new application version necessitates an AMI update on all instances. You are tasked with ensuring that instances running the old AMI are quickly decommissioned. Which termination policy should be implemented to meet this need?

#2. A sizable engineering firm is rolling out a distributed application using Amazon Aurora for its database needs. They require the database to recover within a Recovery Time Objective (RTO) of one minute in the event of service interruption in the primary region, while minimizing administrative efforts. Which strategy should be adopted for the Aurora database to adhere to the cross-region disaster recovery prerequisites?

#3. In the context of secure architectures, a financial institution has implemented a mission-critical platform on an EC2 instance, which is made accessible through an internet-facing Application Load Balancer. AWS WAF has been integrated with the Load Balancer to fortify the application's security. The focus of the security team is to safeguard the application's resource-intensive components. To this end, they intend to impose a limit on the number of sessions to these components. Once the session count exceeds a predefined threshold, further requests should be rejected. What security policy should be devised to offer the necessary level of protection to the application?

#4. A tech firm has recently set up web servers on Amazon EC2 that boast high availability and resilience. These servers are routed through Application Load Balancers for accessibility. Alongside this, the company maintains a less powerful web server on-premises in a data center, which serves as a backup. The EC2 instances in the AWS cloud are designated as the primary servers, with the data center servers as the secondary backup. They plan to employ Amazon Route 53 for orchestrating the failover process. What configuration should be applied to Route 53 health checks to achieve the desired active-passive failover setup?

#5. A burgeoning enterprise is considering migrating their application servers, currently on virtual machines (VMs) within a VMware vCenter-managed on-premises data center, to Amazon EC2 instances in the cloud. These VMs run on a variety of operating systems. To facilitate this transition, the IT team needs detailed data on the on-premises servers' resource utilization, including metrics like CPU usage, disk storage, memory, and network usage. This information is crucial for sizing the EC2 instances appropriately and should be collected in a secure, encrypted format for consultation with the migration experts. What is the optimal method for gathering these server details?

#6. A corporation is in the process of planning the migration of their SQL Servers from an on-site location to the AWS Cloud. The migration strategy needs to be seamless, ensuring minimal downtime and non-disruption of existing operations. Before elevating AWS servers to the role of primary servers, prerequisite tests must be run and the outcomes should be documented. Which cost-effective automated tool is recommended for conducting the SQL Server migration?

#7. A financial institution utilizes Amazon S3 for its data storage needs, which includes a variety of customer data. A routine audit revealed that some S3 buckets contain sensitive information. The operations management is in search of an automated mechanism to scan all the S3 buckets and compile a report highlighting the sensitive data contained within them. Which automated solution can be designed to gather the necessary information?

#8. An e-commerce company specializing in photo printing is preparing to optimize their on-premises IT infrastructure by transferring approximately 50 TB of data to Amazon S3 buckets. To enhance their workflow, they intend to process this data with a custom AWS Lambda function before it's stored in S3. They are in need of a design strategy for a data transfer solution that can handle large volumes and also provide computational capabilities. What is the most suitable design approach for transferring and processing this data?

#9. The Utopia Municipality Corporation has its citizen services application running on EC2 instances while its database remains on-premises due to regulatory compliance. They wish to keep their database on-premises but need a solution to allow seamless interaction between AWS services and the on-premises database. They're seeking a managed solution to enable a consistent hybrid cloud experience with low latency, without transferring or hosting the database in the cloud. As a Solutions Architect, which solution would you recommend to achieve these requirements?

#10. A pharmaceutical research company is gathering a diverse array of sensitive scientific data in various formats and seeks to leverage AWS for constructing a Data Lake to facilitate comprehensive data analysis. A crucial preliminary step involves data cleansing to eliminate any duplicates. Additionally, the chosen solution should provide stringent security measures, offering fine-grained access control down to the column, row, and cell levels within the data. Time is of the essence, and the company requires a rapid deployment of this solution. What technology would you suggest to address these needs?
