質問 # 922
A Solutions Architect created a brand new IAM User with a default setting using AWS CLI. This is intended to be used to send API requests to Amazon S3, DynamoDB, Lambda, and other AWS resources of the company's cloud infrastructure.
Which of the following must be done to allow the user to make API calls to the AWS resources?
正解：A
解説：
You can choose the credentials that are right for your IAM user. When you use the AWS Management Console to create a user, you must choose to at least include a console password or access keys. By default, a brand new IAM user created using the AWS CLI or AWS API has no credentials of any kind.
You must create the type of credentials for an IAM user based on the needs of your user.
Access keys are long-term credentials for an IAM user or the AWS account root user. You can use access keys to sign programmatic requests to the AWS CLI or AWS API (directly or using the AWS SDK).
Users need their own access keys to make programmatic calls to AWS from the AWS Command Line Interface (AWS CLI), Tools for Windows PowerShell, the AWS SDKs, or direct HTTP calls using the APIs for individual AWS services.
To fill this need, you can create, modify, view, or rotate access keys (access key IDs and secret access keys) for IAM users. When you create an access key, IAM returns the access key ID and secret access key. You should save these in a secure location and give them to the user.
The option that says: Do nothing as the IAM User is already capable of sending API calls to your AWS resources is incorrect because by default, a brand new IAM user created using the AWS CLI or AWS API has no credentials of any kind. Take note that in the scenario, you created the new IAM user using the AWS CLI and not via the AWS Management Console, where you must choose to at least include a console password or access keys when creating a new IAM user.
Enabling Multi-Factor Authentication for the user is incorrect because this will still not provide the required Access Keys needed to send API calls to your AWS resources. You have to grant the IAM user with Access Keys to meet the requirement.
Assigning an IAM Policy to the user to allow it to send API calls is incorrect because adding a new IAM policy to the new user will not grant the needed Access Keys needed to make API calls to the AWS resources.

質問 # 923
A company is developing a microservices-based application that needs to handle varying amounts of traffic. The application will be accessed from the internet and must be highly available. The company wants to expose the application by using RESTful APIs. The application must be able to recover automatically in the event of an application failure in an Availability Zone.
Which solution will meet these requirements with the LEAST operational overhead?
正解：C
解説：
AWS Lambda and API Gateway REST APIs are fully managed and scale automatically with demand, minimizing operational overhead. Deploying Lambda functions inherently provides high availability across multiple Availability Zones, so the application can automatically recover from an Availability Zone failure without managing servers. API Gateway Regional endpoints expose RESTful APIs to internet clients with built-in resilience and integration to Lambda.

[Design High-Performing Architectures]
A company has 15 employees. The company stores employee start dates in an Amazon DynamoDB table. The company wants to send an email message to each employee on the day of the employee's work anniversary.
Which solution will meet these requirements with the MOST operational efficiency?
正解：C
解説：
AWS Lambda for Operational Efficiency:
AWS Lambdais a serverless compute service that allows you to run code without provisioning or managing servers. It automatically scales based on the number of invocations and eliminates the need to maintain and monitor EC2 instances, making it far more operationally efficient compared to running a cron job on EC2.
By using Lambda, you pay only for the compute time that your function uses. This is especially beneficial when dealing with lightweight tasks, such as scanning a DynamoDB table and sending email messages once a day.
Amazon DynamoDB:
DynamoDBis a highly scalable, fully managed NoSQL database. The table stores employee start dates, and scanning the table to find the employees who have a work anniversary on the current day is a lightweight operation. Lambda can easily perform this operation using theDynamoDB Scan APIor queries, depending on how the data is structured.
Amazon SNS for Email Notifications:
Amazon Simple Notification Service (SNS)is a fully managed messaging service that supports sending notifications to a variety of endpoints, including email. SNS is well-suited for sendingout email messages to employees, as it can handle the fan-out messaging pattern (sending the same message to multiple recipients).
In this scenario, once Lambda identifies employees who have their work anniversaries, it can use SNS to send the email notifications efficiently. SNS integrates seamlessly with Lambda, and sending emails via SNS is a common pattern for this type of use case.
Event Scheduling:
To automate this daily task, you can schedule the Lambda function usingAmazon EventBridge (formerly CloudWatch Events). EventBridge can trigger the Lambda function on a daily schedule (cron-like scheduling). This avoids the complexity and operational overhead of manually setting up cron jobs on EC2 instances.
Why Not EC2 or SQS?:
Option A & Bsuggest running a cron job on anAmazon EC2instance. This approach requires you to manage, scale, and patch the EC2 instance, which increases operational overhead. Lambda is a better choice because it automatically scales and doesn't require server management.
Amazon Simple Queue Service (SQS)is ideal for decoupling distributed systems but isn't necessary in this context because the goal is to send notifications to employees on their work anniversaries. SQS adds unnecessary complexity for this straightforward use case, whereSNSis the simpler and more efficient solution.
AWS Reference:
AWS Lambda
Amazon SNS
Amazon DynamoDB
Amazon EventBridge
Summary:
UsingAWS Lambdacombined withAmazon SNSto send notifications, and scheduling the function withAmazon EventBridgeto run daily, is the most operationally efficient solution. It leverages AWS serverless technologies, which reduce the need for infrastructure management and provide automatic scaling. Therefore,Option Cis the correct and optimal choice.
質問 # 925
A company uses Amazon Elastic Container Service (Amazon ECS) to run workloads that belong to service teams. Each service team uses an owner tag to specify the ECS containers that the team owns. The company wants to generate an AWS Cost Explorer report that shows how much each service team spends on ECS containers on a monthly basis.
Which combination of steps will meet these requirements in the MOST operationally efficient way? (Select TWO.)
正解：B、C
解説：
To allocate costs based on team ownership, AWS recommends tagging resources using cost allocation tags. Activating the "owner" tag as a cost allocation tag allows AWS Cost Explorer to categorize and group spending. Additionally, filtering for Amazon ECS services enables the visibility into service-specific usage. This approach is both scalable and operationally efficient.

質問 # 926
[Design Secure Architectures]
An application runs on Amazon EC2 instances in private subnets. The application needs to access an Amazon DynamoDB table. What is the MOST secure way to access the table while ensuring that the traffic does not leave the AWS network?
正解：B
解説：
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/vpc-endpoints-dynamodb.html A VPC endpoint for DynamoDB enables Amazon EC2 instances in your VPC to use their private IP addresses to access DynamoDB with no exposure to the public internet. Your EC2 instances do not require public IP addresses, and you don't need an internet gateway, a NAT device, or a virtual private gateway in your VPC. You use endpoint policies to control access to DynamoDB. Traffic between your VPC and the AWS service does not leave the Amazon network.
