Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q274-Q279):

NEW QUESTION # 274
A media company runs an application on multiple Amazon EC2 instances that requires high storage input
/output operations per second (IOPS).
To achieve the necessary performance, a solutions architect wants to stripe multiple Amazon EBS volumes together and attach the volumes to EC2 instances. The solutions architect wants to receive a notification when IOPS are over-provisioned.
Which solution will meet these requirements?

  • A. Create a custom AWS Config rule to monitor the provisioned IOPS for the EBS volumes that are attached to the EC2 instances and to send notifications.
  • B. Adjust the IOPS of each EBS volume daily based on Amazon CloudWatch metrics for IOPS utilization.
  • C. Configure auto scaling for the EBS volumes to automatically increase or decrease IOPS based on the EC2 instance CPU utilization metric.
  • D. Deploy the application on an EC2 instance type that supports the highest possible IOPS.

Answer: A

Explanation:
AWS Config allows for creation of custom rules to monitor EBS configurations. Combined with CloudWatch metrics and Amazon SNS, custom rules can track over-provisioned IOPS and send alerts when thresholds are breached, allowing proactive cost and performance management.
Reference: AWS Documentation - AWS Config with Custom Rules for EBS Monitoring


NEW QUESTION # 275
A company is migrating an online marketplace application from a mainframe system to an Auto Scaling group of Amazon EC2 instances. The EC2 instances access an Amazon Aurora cluster. The application requires a scalable, persistent caching solution to store the results of in-progress transactions and SQL queries.

  • A. Use an Amazon CloudFront distribution with an Amazon S3 bucket as the origin to cache the transactions. Add an Amazon EC2 instance store volume to the EC2 instances for query result caching.
  • B. Use an Amazon ElastiCache (Memcached) cluster to serve transaction and query results.
  • C. Use an Amazon ElastiCache (Redis OSS) cluster to cache the transactions. Add an Amazon EC2 instance store volume to the EC2 instances for query result caching.
  • D. Use an Amazon ElastiCache (Redis OSS) cluster to serve transaction and query results.

Answer: D

Explanation:
Why Option A is Correct:
ElastiCache for Redis: Provides persistent, scalable caching for in-progress transactions and SQL queries.
Redis supports data durability and advanced features, making it suitable for transactional workloads.
* Integration with Aurora: Easily integrates with the Aurora cluster to improve query performance.
Why Other Options Are Not Ideal:
Option B: CloudFront and S3 are unsuitable for transactional caching. EC2 instance store volumes are ephemeral and lack persistence.
* Option C: Memcached does not offer persistence or advanced transactional support, unlike Redis.
* Option D: Combining Redis with EC2 instance store is unnecessary; Redis alone meets all caching requirements.

NEW QUESTION # 276
A company needs to configure a real-time data ingestion architecture for its application. The company needs an API, a process that transforms data as the data is streamed, and a storage solution for the data.
Which solution will meet these requirements with the LEAST operational overhead?

  • A. Configure an Amazon API Gateway API to send data to AWS Glue. Use AWS Lambda functions to transform the data. Use AWS Glue to send the data to Amazon S3.
  • B. Configure an Amazon API Gateway API to send data to an Amazon Kinesis data stream. Create an Amazon Kinesis Data Firehose delivery stream that uses the Kinesis data stream as a data source. Use AWS Lambda functions to transform the data. Use the Kinesis Data Firehose delivery stream to send the data to Amazon S3.
  • C. Deploy an Amazon EC2 instance to host an API that sends data to AWS Glue. Stop source/destination checking on the EC2 instance. Use AWS Glue to transform the data and to send the data to Amazon S3.
  • D. Deploy an Amazon EC2 instance to host an API that sends data to an Amazon Kinesis data stream. Create an Amazon Kinesis Data Firehose delivery stream that uses the Kinesis data stream as a data source. Use AWS Lambda functions to transform the data. Use the Kinesis Data Firehose delivery stream to send the data to Amazon S3.

Answer: B


NEW QUESTION # 277
A company has a stateless web application that runs on AWS Lambda functions that are invoked by Amazon API Gateway. The company v wants to deploy the application across multiple AWS Regions to provide Regional failover capabilities.
What should a solutions architect do to route traffic to multiple Regions?

  • A. Create Amazon Route 53 health checks for each Region. Use an active-active failover configuration.
  • B. Create an Amazon CloudFront distribution with an origin for each Region. Use CloudFront health checks to route traffic.
  • C. Create an Application Load Balancer in the primary Region. Set the target group to point to the API Gateway endpoint hostnames in each Region.
  • D. Create a transit gateway. Attach the transit gateway to the API Gateway endpoint in each Region. Configure the transit gateway to route requests.

Answer: D

Explanation:
This answer is correct because it provides Regional failover capabilities for the online gaming application by using AWS Global Accelerator. AWS Global Accelerator is a networking service that helps you improve the availability, performance, and security of your public applications. Global Accelerator provides two global static public IPs that act as a fixed entry point to your application endpoints, such as NLBs, in different AWS Regions. Global Accelerator uses the AWS global network to route traffic to the optimal regional endpoint based on health, client location, and policies that you configure. Global Accelerator also terminates TCP and UDP traffic at the edge locations, which reduces the number of hops and improves the network performance. By adding AWS Global Accelerator in front of the NLBs, you can achieve Regional failover for your online gaming application.

NEW QUESTION # 278
A company is running an SMB file server in its data center. The file server stores large files that are accessed frequently for the first few days after the files are created. After 7 days the files are rarely accessed.
The total data size is increasing and is close to the company's total storage capacity. A solutions architect must increase the company's available storage space without losing low-latency access to the most recently accessed files. The solutions architect must also provide file lifecycle management to avoid future storage issues.
Which solution will meet these requirements?

  • A. Create an Amazon FSx for Windows File Server file system to extend the company's storage space.
  • B. Install a utility on each user's computer to access Amazon S3. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.
  • C. Create an Amazon S3 File Gateway to extend the company's storage space. Create an S3 Lifecycle policy to transition the data to S3 Glacier Deep Archive after 7 days.
  • D. Use AWS DataSync to copy data that is older than 7 days from the SMB file server to AWS.

Answer: C

Explanation:
Amazon S3 File Gateway is a hybrid cloud storage service that enables on-premises applications to seamlessly use Amazon S3 cloud storage. It provides a file interface to Amazon S3 and supports SMB and NFS protocols.
It also supports S3 Lifecycle policies that can automatically transition data from S3 Standard to S3 Glacier Deep Archive after a specified period of time. This solution will meet the requirements of increasing the company's available storage space without losing low-latency access to the most recently accessed files and providing file lifecycle management to avoid future storage issues.
