Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q487-Q492):

質問 # 487
A healthcare company develops a patient monitoring application that uses AWS AppSync and an AWS Lambda function. The application stores patient data in an Amazon DynamoDB database. The application processes real-time patient vital signs from thousands of IoT devices. The application must support queries from medical staff who access patient historical data. A developer notices significant latency when medical staff query patient histories, specifically for frequently-accessed records of patients currently under observation. The developer observes that the Lambda functions are consuming high read capacity units (RCUs) from DynamoDB. The developer needs to optimize the application ' s performance and maintain data consistency. Which solution will meet these requirements?

A. Increase the Lambda function memory allocation to maximum. Configure provisioned concurrency for the function.
B. Enable response caching in AppSync with a TTL value of 1 hour for all queries. Update the Lambda code to use in-memory caching.
C. Create a caching Lambda function that aggregates patient data periodically and stores it in Amazon S3.
Implement a read-through cache pattern.
D. Implement in-memory caching by using Amazon ElastiCache for frequently-accessed patient records.Configure the Lambda functions to check the cache before querying the database. Set up cache invalidation when patient data is updated.

正解：D

解説：
For frequently accessed data that causes high RCUs and latency in DynamoDB, ElastiCache (Redis or Memcached) is the recommended solution. It sits in front of DynamoDB as a high-speed, in-memory cache.
Implementing a " Cache-Aside " or " Read-Through " pattern reduces the load on DynamoDB and provides sub-millisecond response times for queries. Invalidation ensures that when vital signs are updated, the cache is refreshed, maintaining data consistency.

質問 # 488
A company runs a batch processing application by using AWS Lambda functions and Amazon API Gateway APIs with deployment stages for development, user acceptance testing and production A development team needs to configure the APIs in the deployment stages to connect to third-party service endpoints.
Which solution will meet this requirement?

A. Store the third-party service endpoints in API Gateway stage variables that correspond to the stage
B. Store the third-party service endpoints in Lambda layers that correspond to the stage
C. Store the third-party service endpoint for each environment in AWS AppConfig
D. Encode the third-party service endpoints as query parameters in the API Gateway request URL.

正解：A

解説：
API Gateway Stage Variables: These are designed for configuring dynamic values for your APIs in different deployment stages (dev, test, prod). Here's how to use them for third-party endpoints:
In the API Gateway console, access the "Stages" section of your API.
For each stage, create a stage variable named something like thirdPartyEndpoint.
Set the value of this variable to the actual endpoint URL for that specific environment.
When configuring API requests within your API Gateway method, reference this endpoint using ${stageVariables.thirdPartyEndpoint}.
Why Stage Variables Excel Here:
Environment Isolation: This approach keeps the endpoint configuration specific to each deployment stage, ensuring the right endpoints are used during development, testing, and production cycles.
Ease of Management: You manage the endpoints directly through the API Gateway console without additional infrastructure.

質問 # 489
A company has an online web application that includes a product catalog. The catalog is stored in an Amazon S3 bucket that is named DOC-EXAMPLE-BUCKET. The application must be able to list the objects in the S3 bucket and must be able to download objects through an IAM policy.
Which policy allows MINIMUM access to meet these requirements?

正解：B

質問 # 490
A developer is working on an ecommerce website The developer wants to review server logs without logging in to each of the application servers individually. The website runs on multiple Amazon EC2 instances, is written in Python, and needs to be highly available How can the developer update the application to meet these requirements with MINIMUM changes?

A. Install the unified Amazon CloudWatch agent on the EC2 instances Configure the agent to push the application logs to CloudWatch
B. Set up centralized logging by using Amazon OpenSearch Service, Logstash, and OpenSearch Dashboards
C. Rewrite the application to be cloud native and to run on AWS Lambda, where the logs can be reviewed in Amazon CloudWatch
D. Scale down the application to one larger EC2 instance where only one instance is recording logs

正解：A

解説：
* Centralized Logging Benefits: Centralized logging is essential for operational visibility in scalable systems, especially those using multiple EC2 instances like our e-commerce website. CloudWatch provides this capability, along with other monitoring features.
* CloudWatch Agent: This is the best way to send custom application logs from EC2 instances to CloudWatch. Here's the process:
* Install the CloudWatch agent on each EC2 instance.
* Configure the agent with a configuration file, specifying:
* Which log files to collect.
* The format in which to send logs to CloudWatch (e.g., JSON).
* The specific CloudWatch Logs log group and log stream for these logs.
* Viewing and Analyzing Logs: Once the agent is pushing logs, use the CloudWatch Logs console or API:
* View and search the logs across all instances.
* Set up alarms based on log events.
* Use CloudWatch Logs Insights for sophisticated queries and analysis.

質問 # 491
A developer is building a microservices-based application by using Python on AWS and several AWS services The developer must use AWS X-Ray The developer views the service map by using the console to view the service dependencies. During testing, the developer notices that some services are missing from the service map What can the developer do to ensure that all services appear in the X-Ray service map?

A. Modify the X-Ray Python agent configuration in each service to increase the sampling rate
B. Increase the X-Ray service map timeout value in the X-Ray console
C. Enable X-Ray data aggregation in Amazon CloudWatch Logs for all the services that the application uses
D. Instrument the application by using the X-Ray SDK for Python. Install the X-Ray SDK for all the services that the application uses

正解：D

解説：
* AWS X-Ray SDK: The primary way to enable X-Ray tracing within applications. The SDK sends data about requests and subsegments to the X-Ray daemon for service map generation.
* Instrumenting All Services: To visualize a complete microservice architecture on the service map, each relevant service must include the X-Ray SDK.
