Question 68

A company's application has an AWS Lambda function that processes messages from loT devices. The company wants to monitor the Lambda function to ensure that the Lambda function is meeting its required service level agreement (SLA).

A developer must implement a solution to determine the application's throughput in near real time. The throughput must be based on the number of messages that the Lambda function receives and processes in a given time period. The Lambda function performs initialization and post-processing steps that must not factor into the throughput measurement.

What should the developer do to meet these requirements?

Options:

Use the Lambda function's ConcurrentExecutions metric in Amazon CloudWatch to measure the throughput.

Modify the application to log the calculated throughput to Amazon CloudWatch Logs. Use Amazon EventBridge to invoke a separate Lambda function to process the logs on a schedule.

Modify the application to publish custom Amazon CloudWatch metrics when the Lambda function receives and processes each message. Use the metrics to calculate the throughput.

Use the Lambda function's Invocations metric and Duration metric to calculate the throughput in Amazon CloudWatch.

Question 69

A company regularly receives route status updates from its delivery trucks as events in Amazon EventBridge. The company is building an API-based application in a VPC that will consume and process the events to create a delivery status dashboard. The API application must not be available by using public IP addresses because of security and compliance requirements.

How should the company send events from EventBridge to the API application?

Options:

Create an AWS Lambda function that runs in the same VPC as the API application. Configure the function as an EventBridge target. Use the function to send events to the API.

Create an internet-facing Application Load Balancer (ALB) in front of the API application. Associate a security group with rules that block access from all external sources except for EventBridge. Configure the ALB as an EventBridge target.

Create an internet-facing Network Load Balancer (NLB) in front of the API application. Associate a security group with rules that block access from all external sources except for EventBridge. Configure the NLB as an EventBridge target.

Use the application API endpoint in the VPC as a target for EventBridge. Send events directly to the application API endpoint from EventBridge.

Question 70

A developer is testing a new file storage application that uses an Amazon CloudFront distribution to serve content from an Amazon S3 bucket. The distribution accesses the S3 bucket by using an origin access identity (OAI). The S3 bucket's permissions explicitly deny access to all other users.

The application prompts users to authenticate on a login page and then uses signed cookies to allow users to access their personal storage directories. The developer has configured the distribution to use its default cache behavior with restricted viewer access and has set the origin to point to the S3 bucket. However, when the developer tries to navigate to the login page, the developer receives a 403 Forbidden error.

The developer needs to implement a solution to allow unauthenticated access to the login page. The solution also must keep all private content secure.

Which solution will meet these requirements?

Options:

Add a second cache behavior to the distribution with the same origin as the default cache behavior. Set the path pattern for the second cache behavior to the path of the login page, and make viewer access unrestricted. Keep the default cache behavior's settings unchanged.

Add a second cache behavior to the distribution with the same origin as the default cache behavior. Set the path pattern for the second cache behavior to *, and make viewer access restricted. Change the default cache behavior's path pattern to the path of the login page, and make viewer access unrestricted.

Add a second origin as a failover origin to the default cache behavior. Point the failover origin to the S3 bucket. Set the path pattern for the primary origin to *, and make viewer access restricted. Set the path pattern for the failover origin to the path of the login page, and make viewer access unrestricted.

Add a bucket policy to the S3 bucket to allow read access. Set the resource on the policy to the Amazon Resource Name (ARN) of the login page object in the S3 bucket. Add a CloudFront function to the default cache behavior to redirect unauthorized requests to the login page's S3 URL.

Question 71

An application stores user data in Amazon S3 buckets in multiple AWS Regions. A developer needs to implement a solution that analyzes the user data in the S3 buckets to find sensitive information. The analysis findings from all the S3 buckets must be available in the eu-west-2 Region.

Which solution will meet these requirements with the LEAST development effort?

Options:

Create an AWS Lambda function to generate findings. Program the Lambda function to send the findings to another S3 bucket in eu-west-2.

Configure Amazon Made to generate findings. Use Amazon EventBridge to create rules that copy the findings to eu-west-2.

Configure Amazon Inspector to generate findings. Use Amazon EventBridge to create rules that copy the findings to eu-west-2.

Configure Amazon Macie to generate findings and to publish the findings to AWS CloudTrail. Use a CloudTrail trail to copy the results to eu-west-2.
