Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q524-Q529):

NEW QUESTION # 524
[Design High-Performing Architectures]
A company has an application that uses an Amazon DynamoDB table for storage. A solutions architect discovers that many requests to the table are not returning the latest dat a. The company's users have not reported any other issues with database performance. Latency is in an acceptable range.
Which design change should the solutions architect recommend?

Answer: C

Explanation:
The most suitable design change for the company's application is to request strongly consistent reads for the table. This change will ensure that the requests to the table return the latest data, reflecting the updates from all prior write operations.
Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB supports two types of read consistency: eventually consistent reads and strongly consistent reads.By default, DynamoDB uses eventually consistent reads, unless users specify otherwise1.
Eventually consistent reads are reads that may not reflect the results of a recently completed write operation. The response might not include the changes because of the latency of propagating the data to all replicas. If users repeat their read request after a short time, the response should return the updated data.Eventually consistent reads are suitable for applications that do not require up-to-date data or can tolerate eventual consistency1.
Strongly consistent reads are reads that return a result that reflects all writes that received a successful response prior to the read. Users can request a strongly consistent read by setting the ConsistentRead parameter to true in their read operations, such as GetItem, Query, or Scan.Strongly consistent reads are suitable for applications that require up-to-date data or cannot tolerate eventual consistency1.
The other options are not correct because they do not address the issue of read consistency or are not relevant for the use case. Adding read replicas to the table is not correct because this option is not supported by DynamoDB. Read replicas are copies of a primary database instance that can serve read-only traffic and improve availability and performance.Read replicas are available for some relational database services, such as Amazon RDS or Amazon Aurora, but not for DynamoDB2. Using a global secondary index (GSI) is not correct because this option is not related to read consistency. A GSI is an index that has a partition key and an optional sort key that are different from those on the base table.A GSI allows users to query the data in different ways, with eventual consistency3. Requesting eventually consistent reads for the table is not correct because this option is already the default behavior of DynamoDB and does not solve the problem of requests not returning the latest data.

Working with read replicas - Amazon Relational Database Service
Working with global secondary indexes - Amazon DynamoDB


NEW QUESTION # 525
A solutions architect is designing a multi-Region disaster recovery (DR) strategy for a company. The company runs an application on Amazon EC2 instances in Auto Scaling groups that are behind an Application Load Balancer (ALB). The company hosts the application in the company's primary and secondary AWS Regions.
The application must respond to DNS queries from the secondary Region if the primary Region fails. Only one Region must serve traffic at a time.
Which solution will meet these requirements?

Answer: D

Explanation:
Amazon Route 53 supports failover routing policies, which use health checks to route DNS queries to a secondary Region only if the primary endpoint fails. This design ensures only one Region is active for traffic at any given time. This is the recommended architecture for active-passive, multi-Region DR strategies.
AWS Documentation Extract:
"Failover routing lets you route traffic to a primary resource, such as a web server in one Region, and a secondary resource in another Region. If the primary fails, Route 53 can route traffic to the secondary resource automatically." (Source: Amazon Route 53 documentation, Routing Policy Types) A, D: These options do not configure DNS failover for external users.
C: Geolocation routing is for regional distribution, not DR failover.


NEW QUESTION # 526
A company runs an application on several Amazon EC2 instances. Multiple Amazon Elastic Block Store (Amazon EBS) volumes are attached to each EC2 instance. The company needs to back up the configurations and the data of the EC2 instances every night. The application must be recoverable in a secondary AWS Region. Which solution will meet these requirements in the MOST operationally efficient way?

Answer: A

Explanation:
AWS Backup is a fully managed backup service that can create backup plans for EC2 instances, including both instance configurations and attached EBS volumes, with scheduled and cross- Region copy capabilities. By adding the EC2 instances to the resource assignment in the backup plan, AWS Backup automatically backs up all configurations and attached EBS volumes, and can copy backups to a secondary Region for disaster recovery, providing the highest operational efficiency with the least manual effort.


NEW QUESTION # 527
A company wants to use AWS Systems Manager to manage a fleet of Amazon EC2 instances.
According to the company's security requirements, no EC2 instances can have internet access. A solutions architect needs to design network connectivity from the EC2 instances to Systems Manager while fulfilling this security obligation. Which solution will meet these requirements?

Answer: C

Explanation:
Configuring an interface VPC endpoint for Systems Manager enables private connectivity between EC2 instances in a private subnet and Systems Manager without requiring internet access, fully meeting the security requirement while minimizing operational overhead.


NEW QUESTION # 528
A company has an internal application that runs on Amazon EC2 instances in an Auto Scaling group. The EC2 instances are compute optimized and use Amazon Elastic Block Store (Amazon EBS) volumes.
The company wants to identify cost optimizations across the EC2 instances, the Auto Scaling group, and the EBS volumes.
Which solution will meet these requirements with the MOST operational efficiency?

Answer: D

Explanation:
* Requirement Analysis: The company wants to identify cost optimizations for EC2 instances, the Auto Scaling group, and EBS volumes with high operational efficiency.
* AWS Compute Optimizer: This service provides actionable recommendations to help optimize your AWS resources, including EC2 instances, Auto Scaling groups, and EBS volumes.
* Cost Recommendations: Compute Optimizer analyzes the utilization of resources and provides specific recommendations for rightsizing or optimizing the configurations.
* Operational Efficiency: Using Compute Optimizer automates the process of identifying cost-saving opportunities, reducing the need for manual analysis.
* Implementation:
* Enable AWS Compute Optimizer for your AWS account.
* Review the recommendations provided for EC2 instances, Auto Scaling groups, and EBS volumes.
* Conclusion: This solution provides a comprehensive, automated approach to identifying cost optimizations with minimal operational effort.
