Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q98-Q103):

質問 # 98
A developer is designing an event-driven architecture. An AWS Lambda function that processes data needs to push processed data to a subset of four consumer Lambda functions. The data must be routed based on the value of one field in the data.
Which solution will meet these requirements with the LEAST operational overhead?

A. Create a single Amazon Simple Notification Service {Amazon SNS) topic. Subscribe the four consumer Lambda functions to the topic. Add SNS subscription filter policies to each subscription. Configure the data-processing Lambda function to publish to the topic.
B. Create an Amazon Simple Queue Service {Amazon SQS) queue and even! source mapping for each consumer Lambda function. Add message routing logic to the data-processing Lambda function.
C. Create a separate Amazon Simple Notification Service (Amazon SNS) topic and subscription for each consumer Lambda function. Add message routing logic to the data-processing Lambda function to publish to the appropriate topic.
D. Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the four consumer Lambda functions to the topic. Add message filtering logic to each consumer Lambda function. Subscribe the data-processing Lambda function to the SNS topic.

正解：D

質問 # 99
A company is developing a weather forecast application that displays forecasts for cities within a single country. Weather data is stored in an Amazon DynamoDB table named Forecasts with attributes CityId, Temperature, and ForecastDate.
The application is read heavy. Most read requests target the current day's forecast for a small number of very large cities. The company must design a partition key strategy that ensures the most even distribution of read traffic.
Which solution will meet these requirements?

A. Use CityId with a calculated suffix as the partition key and ForecastDate as the sort key.
B. Use a numeric index as the partition key and ForecastDate as the sort key.
C. Use ForecastDate as the partition key and CityId as the sort key.
D. Use ForecastDate with a calculated suffix as the partition key and CityId as the sort key.

正解：A

解説：
Amazon DynamoDB performance depends heavily on partition key design. AWS documentation warns against access patterns that repeatedly target the same partition key, as this causes hot partitions, even in on- demand mode.
In this scenario, most reads focus on the current day's forecast for a small number of large cities. Using CityId alone as the partition key would cause hot partitions for those cities. Adding a calculated suffix (such as a hash or modulo value) to CityId spreads read requests across multiple partitions while still allowing efficient querying.
Using ForecastDate as the partition key (Options C and D) would concentrate traffic on a single value (today' s date), creating severe hot partition issues. Option B lacks a meaningful access pattern and complicates queries.
AWS documentation explicitly recommends key-suffix techniques for workloads with skewed access patterns to distribute traffic evenly. Therefore, using CityId with a calculated suffix as the partition key is the correct design.

質問 # 100
A developer is creating a mobile application that will not require users to log in.
What is the MOST efficient method to grant users access to AWS resources'?

A. Create an AWS Lambda function to create an 1AM user when a user accesses the application.
B. Use Amazon Cognito to associate unauthenticated users with an IAM role that has limited access to resources.
C. Create credentials using AWS KMS and apply these credentials to users when using the application.
D. Use an identity provider to securely authenticate with the application.

正解：B

解説：
Explanation
This solution is the most efficient method to grant users access to AWS resources without requiring them to log in. Amazon Cognito is a service that provides user sign-up, sign-in, and access control for web and mobile applications. Amazon Cognito identity pools support both authenticated and unauthenticated users.
Unauthenticated users receive access to your AWS resources even if they aren't logged in with any of your identity providers (IdPs). You can use Amazon Cognito to associate unauthenticated users with an IAM role that has limited access to resources, such as Amazon S3 buckets or DynamoDB tables. This degree of access is useful to display content to users before they log in or to allow them to perform certain actions without signing up. Using an identity provider to securely authenticate with the application will require users to log in, which does not meet the requirement. Creating an AWS Lambda function to create an IAM user when a user accesses the application will incur unnecessary costs and complexity, and may pose security risks if not implemented properly. Creating credentials using AWS KMS and applying them to users when using the application will also incur unnecessary costs and complexity, and may not provide fine-grained access control for resources.

質問 # 101
A company has an application that is hosted on Amazon EC2 instances. The application stores objects in an Amazon S3 bucket and allows users to download objects from the S3 bucket. A developer turns on S3 Block Public Access for the S3 bucket. After this change, users report errors when they attempt to download objects. The developer needs to implement a solution so that only users who are signed in to the application can access objects in the S3 bucket.
Which combination of steps will meet these requirements in the MOST secure way? (Choose two.)

A. Create an IAM user with an appropriate policy. Store the access key ID and secret access key on the EC2 instances.
B. Modify the application to use the S3 GeneratePresignedUrl API call.
C. Modify the application to use the S3 GetObject API call and to return the object handle to the user.
D. Modify the application to delegate requests to the S3 bucket.
E. Create an EC2 instance profile and role with an appropriate policy. Associate the role with the EC2 instances.

正解：B、E

質問 # 102
A developer has AWS Lambda functions that need to access a company's internal data science libraries and reference data. Separate teams manage the libraries and the data. The teams must be able to update and upload new data independently. The Lambda functions are connected to the company's central VPC.
Which solution will provide the Lambda functions with access to the libraries and data?

A. Set up an Amazon FSx for Windows File Server file system with mount targets in the central VPC.Configure the Lambda functions to mount the Amazon FSx file system. Update the Lambda function execution roles to give the functions to access the Amazon FSx file system.
B. Set up an Amazon Elastic File System (Amazon EFS) file system with mount targets in the central VPConfigure the Lambda functions to mount the EFS file system. Update the Lambda function execution roles to give the functions to access the EFS file system.
C. Compress the libraries and reference data in a Lambda /tmp folder. Update the Lambda function code to reference the files in the /tmp folder.
D. Attach an Amazon Elastic Block Store (Amazon EBS) volume to the Lambda functions by using EBS Multi-Attach in the central VPC. Update the Lambda function execution roles to give the functions to access the EBS volume. Update the Lambda function code to reference the files in the EBS volume.

正解：B

解説：
Configure a function to mount an Amazon Elastic File System (Amazon EFS) file system to a local directory.
