Question 52 (Topic 1)

A developer needs to configure an AWS Lambda function to make HTTP POST requests to an internal application. The application is in the same AWS account that hosts the function. The internal application runs on Amazon EC2 instances in a private subnet within a VPC. Which solution will meet these requirements?

Select an option, then click Submit answer.

○ Configure a VPC endpoint to connect to the private subnet. Attach the endpoint to the Lambda function.
○ Attach the Lambda function to the VPC and to the private subnet.
○ Configure a VPN connection between the Lambda function and the private subnet. Attach the VPN to the Lambda function.
○ Configure the VPC route table to include the Lambda function’s IP address.

Reference / correct answer:

Attach the Lambda function to the VPC and to the private subnet.

Most accepted answer: B. Attach the Lambda function to the VPC and to the private subnet.

Community votes: B=2, D=1

Selected Answer: B When your Lambda function needs to access resources within a VPC, such as Amazon EC2 instances in a private subnet, you need to configure the Lambda function to run within that VPC. This is done by specifying the VPC, subnet(s), and security group(s) in the Lambda configuration. Once attached to the VPC and subnet, the Lambda function can make HTTP requests to the internal application running on the EC2 instances in the private subnet. upvoted 5 times

Selected Answer: B Lambda functions do not have fixed IP addresses, making it impractical to add them to a route table upvoted 1 times

Selected Answer: D Lambda Function logs request information (e.g., timestamp, processing time, status) using the default logging mechanism. Create custom CloudWatch metrics in a specific namespace based on these logs. upvoted 1 times YUICH 1 year, 7 months ago Sorry I changed my opinion. The answer is B. Lambda functions do not have fixed IP addresses, making it impractical to add them to a route table. Instead, attaching the Lambda function to the VPC and configuring security groups appropriately is the recommended approach. upvoted 3 times ...

Question 53 (Topic 1)

A developer is deploying an application on an Amazon Elastic Container Service (Amazon ECS) cluster that uses AWS Fargate. The developer is using a Docker container with an Ubuntu image. The developer needs to implement a solution to store application data that is available from multiple ECS tasks. The application data must remain accessible after the container is terminated. Which solution will meet these requirements?

Select an option, then click Submit answer.

○ Attach an Amazon FSx for Windows File Server volume to the container definition.
○ Specify the DockerVolumeConfiguration parameter in the ECS task definition to attach a Docker volume.
○ Create an Amazon Elastic File System (Amazon EFS) file system. Specify the mountPoints attribute and the efsVolumeConfiguration attribute in the ECS task definition.
○ Create an Amazon Elastic Block Store (Amazon EBS) volume. Specify the mount point configuration in the ECS task definition.

Question 54 (Topic 1)

A developer is creating a stock trading application. The developer needs a solution to send text messages to application users to confirmation when a trade has been completed. The solution must deliver messages in the order a user makes stock trades. The solution must not send duplicate messages. Which solution will meet these requirements?

Select an option, then click Submit answer.

○ Configure the application to publish messages to an Amazon Data Firehose delivery stream. Configure the delivery stream to have a destination of each user’s mobile phone number that is passed in the trade confirmation message.
○ Create an Amazon Simple Queue Service (Amazon SQS) FIFO queue. Use the SendMessageIn API call to send the trade confirmation messages to the queue. Use the SendMessageOut API to send the messages to users by using the information provided in the trade confirmation message.
○ Configure a pipe in Amazon EventBridge Pipes. Connect the application to the pipe as a source. Configure the pipe to use each user’s mobile phone number as a target. Configure the pipe to send incoming events to the users.
○ Create an Amazon Simple Notification Service (SNS) FIFO topic. Configure the application to use the AWS SDK to publish notifications to the SNS topic to send SMS messages to the users.
