最新的 AWS Certified Solutions Architect SAA-C03 免費考試真題 (Q130-Q135):

問題 #130
A company runs an application on an Amazon ECS cluster that uses AWS Fargate on-demand capacity. The application cannot tolerate any sudden interruptions.
The company wants to optimize costs for the application and ensure that the application remains operational.
Which solution will meet these requirements?

答案：C

解題說明：
A Compute Savings Plan reduces the cost of AWS Fargate on-demand usage while keeping the application on interruption-free capacity. This preserves availability for workloads that cannot tolerate sudden interruptions and provides cost optimization without changing the deployment model.


問題 #131
An ecommerce company is building a distributed application that involves several serverless functions and AWS services to complete order-processing tasks. These tasks require manual approvals as part of the workflow A solutions architect needs to design an architecture for the order-processing application The solution must be able to combine multiple AWS Lambda functions into responsive serverless applications The solution also must orchestrate data and services that run on Amazon EC2 instances, containers, or on-premises servers Which solution will meet these requirements with the LEAST operational overhead?

答案：A


問題 #132
A company has an industrial application that controls a process in real time. The company plans to rearchitect the application to distribute jobs across several Amazon EC2 instances in a VPC. The solution needs to maximize the network throughput and minimize the network latency between the instances.

答案：D

解題說明：
Comprehensive and Detailed
For applications requiring high network throughput and low latency between EC2 instances, AWS recommends using a Cluster Placement Group:
Cluster Placement Group: Packs instances close together inside an Availability Zone, enabling workloads to achieve the low-latency network performance necessary for tightly-coupled node-to-node communication.
Enhanced Networking: Selecting instance types that support enhanced networking provides higher bandwidth, higher packet-per-second (PPS) performance, and consistently lower inter-instance latencies.
By combining a Cluster Placement Group with enhanced networking-enabled instance types, the company can meet the stringent performance requirements of its real-time industrial application.


問題 #133
An events company runs a web application on Amazon EKS that uses an Amazon DynamoDB table. The table has 1,000 RCUs and 500 WCUs provisioned. The application uses eventually consistent reads.
Traffic is usually low but occasionally spikes. During spikes, DynamoDB throttles requests, causing user- facing errors.
What should a solutions architect do to reduce these errors?

答案：A

解題說明：
The application experiences unpredictable traffic spikes, which exceed the provisioned read and write capacity of the DynamoDB table, resulting in throttling errors. This is a classic scenario where on-demand capacity mode is the most appropriate solution.
Option A is correct because DynamoDB on-demand capacity automatically scales to handle sudden increases in traffic without requiring capacity planning. This eliminates throttling during unpredictable spikes and removes the operational burden of managing RCUs and WCUs. On-demand mode is particularly well-suited for workloads with variable or spiky access patterns.
Option B is incorrect because DynamoDB does not support read replicas in the same way as relational databases. Option C reduces cost for predictable workloads but does not prevent throttling if capacity limits are exceeded. Option D increases read cost and does not address capacity constraints.
Therefore, A is the best solution to improve resilience, eliminate throttling errors, and ensure a smooth user experience during traffic surges.


問題 #134
A company's application is deployed on Amazon EC2 instances and uses AWS Lambda functions for an event-driven architecture. The company uses nonproduction development environments in a different AWS account to test new features before the company deploys the features to production.
The production instances show constant usage because of customers in different time zones. The company uses nonproduction instances only during business hours on weekdays. The company does not use the nonproduction instances on the weekends. The company wants to optimize the costs to run its application on AWS.
Which solution will meet these requirements MOST cost-effectively?

答案：A

解題說明：
Compute Savings Plans offer the most flexible and cost-effective solution for the production instances, as they provide significant savings (up to 66%) for both EC2 and AWS Lambda usage, while allowing flexibility in the type of instance family, size, and even region. For nonproduction instances, using On-Demand Instances ensures you only pay for the instances when they are running, and shutting them down during off- hours further optimizes cost.
Key AWS features:
* Compute Savings Plans: Provide savings based on consistent usage, making it ideal for production environments with steady load.
* On-Demand Instances: Suitable for nonproduction environments that are used intermittently. Shutting them down when not in use avoids unnecessary costs.
* AWS Documentation: According to AWS's cost optimization best practices, using a combination of Savings Plans for production and On-Demand Instances for nonproduction environments that are used sparingly results in optimal cost savings.
