Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q284-Q289):

質問 # 284
A developer maintains a critical business application that uses Amazon DynamoDB as the primary data store The DynamoDB table contains millions of documents and receives 30-60 requests each minute The developer needs to perform processing in near-real time on the documents when they are added or updated in the DynamoDB table How can the developer implement this feature with the LEAST amount of change to the existing application code?

A. Update the application to send a PutEvents request to Amazon EventBridge. Create an EventBridge rule to invoke an AWS Lambda function to process the documents.
B. Update the application to synchronously process the documents directly after the DynamoDB write
C. Set up a cron job on an Amazon EC2 instance Run a script every hour to query the table for changes and process the documents
D. Enable a DynamoDB stream on the table Invoke an AWS Lambda function to process the documents.

正解：D

解説：
* DynamoDB Streams: Capture near real-time changes to DynamoDB tables, triggering downstream actions.
* Lambda for Processing: Lambda functions provide a serverless way to execute code in response to events like DynamoDB Stream updates.
* Minimal Code Changes: This solution requires the least modifications to the existing application.

質問 # 285
A large company has its application components distributed across multiple AWS accounts. The company needs to collect and visualize trace data across these accounts.
What should be used to meet these requirements?

A. Amazon CloudWatch
B. Amazon VPC flow logs
C. Amazon OpenSearch Service
D. AWS X-Ray

正解：D

質問 # 286
An ecommerce startup is preparing for an annual sales event. As the traffic to the company's application increases, the development team wants to be notified when the Amazon EC2 instance's CPU utilization exceeds 80%.
Which solution will meet this requirement?

A. Create an AWS Lambda function that queries the AWS CloudTrail logs for the CPUUtilization metric every 15 minutes and sends a notification to an Amazon SNS topic when the CPU utilization exceeds
80%.
B. Create a custom AWS CloudTrail alarm that sends a notification to an Amazon SNS topic when the CPU utilization exceeds 80%.
C. Create a cron job on the EC2 instance that invokes the --describe-instance-information command on the host instance every 15 minutes and sends the results to an Amazon SNS topic.
D. Create a custom Amazon CloudWatch alarm that sends a notification to an Amazon SNS topic when the CPU utilization exceeds 80%.

正解：D

解説：
Step-by-Step Breakdown:
Requirement Summary:
* Get notified when EC2 CPU Utilization > 80%
Option A: CloudWatch Alarm with SNS
* Correct and standard AWS practice
* CloudWatch automatically collects EC2 metrics, including CPUUtilization.
* You can set a CloudWatch Alarm with a threshold (80% in this case).
* Then, trigger an SNS notification to email, SMS, Lambda, etc.
Option B: AWS CloudTrail alarm
* Incorrect: CloudTrail logs API activity, not performance metrics.
* It doesn't track metrics like CPU utilization.
Option C: Cron job on EC2 running --describe-instance-information
* Incorrect: This doesn't give CPU usage.
* Also inefficient, and polling is bad practice when CloudWatch already monitors this natively.
Option D: Lambda function querying CloudTrail for CPU usage
* Incorrect and conceptually flawed.
* CloudTrail does not store performance metrics; CloudWatch does.

質問 # 287
A developer is deploying a company's application to Amazon EC2 instances The application generates gigabytes of data files each day The files are rarely accessed but the files must be available to the application's users within minutes of a request during the first year of storage The company must retain the files for 7 years.
How can the developer implement the application to meet these requirements MOST cost-effectively?

A. Store the files in an Amazon S3 bucket Use the S3 Glacier Instant Retrieval storage class Create an S3 Lifecycle policy to transition the files to the S3 Glacier Deep Archive storage class after 1 year
B. Store the files in an Amazon S3 bucket. Use the S3 Standard storage class. Create an S3 Lifecycle policy to transition the files to the S3 Glacier Flexible Retrieval storage class after 1 year.
C. Store the files on an Amazon Elastic Block Store (Amazon EBS) volume Use Amazon Data Lifecycle Manager (Amazon DLM) to create snapshots of the EBS volumes and to store those snapshots in Amazon S3
D. Store the files on an Amazon Elastic File System (Amazon EFS) mount. Configure EFS lifecycle management to transition the files to the EFS Standard-Infrequent Access (Standard-IA) storage class after 1 year.

正解：A

解説：
Amazon S3 Glacier Instant Retrieval is an archive storage class that delivers the lowest-cost storage for long- lived data that is rarely accessed and requires retrieval in milliseconds. With S3 Glacier Instant Retrieval, you can save up to 68% on storage costs compared to using the S3 Standard-Infrequent Access (S3 Standard-IA) storage class, when your data is accessed once per quarter.https://aws.amazon.com/s3/storage-classes/glacier
/instant-retrieval/
* Understanding Storage Requirements:
* Files are large and infrequently accessed, but need to be available within minutes when requested in the first year.
* Long-term (7-year) retention is required.
* Cost-effectiveness is a top priority.
* Why S3 Glacier Instant Retrieval:
* Matches the retrieval requirements (access within minutes).
* More cost-effective than S3 Standard for infrequently accessed data.
* Simpler to use than traditional Glacier where retrievals take hours.
* Why S3 Glacier Deep Archive:
* Most cost-effective S3 storage class for long term archival.
* Meets the 7-year retention requirement.
* S3 Lifecycle Policy:
* Automate the transition from Glacier Instant Retrieval to Glacier Deep Archive after one year.
* Optimize costs by matching storage classes to access patterns.

質問 # 288
A developer has a financial application. The application uses AWS Secrets Manager to manage an Amazon RDS for PostgreSQL database's username and password. The developer needs to rotate thepassword while maintaining the application's high availability. Which solution will meet these requirements with LEAST development effort?

A. Rotate the secret by using the single-user rotation strategy. Update the application with an appropriate retry strategy to handle authentication failures.
B. Rotate the secret by using multivalue answer rotation. Update the application with an appropriate retry strategy to handle authentication failures.
C. Use the PostgreSQL client to create a new database username and password. Include the new secret values by performing an immediate rotation. Use the AWS CLI to update the RDS database password.
Perform an immediate rotation of the Secrets Manager secrets.
D. Rotate the secret by using the alternating-users rotation strategy. Update the application with an appropriate retry strategy to handle authentication failures.

正解：A

解説：
Requirement Summary:
* Secrets managed inAWS Secrets Manager
* DB:Amazon RDS for PostgreSQL
* Needautomated password rotation
* Must maintainhigh availability
* Least development effort
Rotation Strategies:
#Single-user rotation strategy
* #Simplest to implement
* The secret containsone set of credentialsused by app and rotation logic
* #Supportsautomated rotation
* AWS providesbuilt-in Lambda rotation templatesfor RDS
A: Alternating-users strategy
* ##More complex
* Requires application toswitch usersduring rotation window
B: Manual secret + CLI rotation
* #Too much manual work
* Not scalable or reliable
C: Multivalue answer rotation
* #Not a valid strategy in this context
* Doesn't apply to Secrets Manager
* Secrets Manager rotation strategies:https://docs.aws.amazon.com/secretsmanager/latest/userguide

* RDS PostgreSQL secret rotation:https://docs.aws.amazon.com/secretsmanager/latest/userguide/rotating- secrets_strategies.html#rotating-secrets-single-user
