Questions # 146:

A company gives users the ability to upload images from a custom application. The upload process invokes an AWS Lambda function that processes and stores the image in an Amazon S3 bucket. The application invokes the Lambda function by using a specific function version ARN.

The Lambda function accepts image processing parameters by using environment variables. The company often adjusts the environment variables of the Lambda function to achieve optimal image processing output. The company tests different parameters and publishes a new function version with the updated environment variables after validating results. This update process also requires frequent changes to the custom application to invoke the new function version ARN. These changes cause interruptions for users.

A solutions architect needs to simplify this process to minimize disruption to users.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Directly modify the environment variables of the published Lambda function version. Use the SLATEST version to test image processing parameters.

Create an Amazon DynamoDB table to store the image processing parameters. Modify the Lambda function to retrieve the image processing parameters from the DynamoDB table.

Directly code the image processing parameters within the Lambda function and remove the environment variables. Publish a new function version when the company updates the parameters.

Create a Lambda function alias. Modify the client application to use the function alias ARN. Reconfigure the Lambda alias to point to new versions of the function when the company finishes testing.

Questions # 147:

A company uses AWS CloudFormation to deploy applications within multiple VPCs that are all attached to a transit gateway Each VPC that sends traffic to the public internet must send the traffic through a shared services VPC Each subnet within a VPC uses the default VPC route table and the traffic is routed to the transit gateway The transit gateway uses its default route table for any VPC attachment

A security audit reveals that an Amazon EC2 instance that is deployed within a VPC can communicate with an EC2 instance that is deployed in any of the company's other VPCs A solutions architect needs to limit the traffic between the VPCs. Each VPC must be able to communicate only with a predefined, limited set of authorized VPCs.

What should the solutions architect do to meet these requirements'?

Options:

Update the network ACL of each subnet within a VPC to allow outbound traffic only to the authorized VPCs Remove all deny rules except the default deny rule.

Update all the security groups that are used within a VPC to deny outbound traffic to security groups that are used within the unauthorized VPCs

Create a dedicated transit gateway route table for each VPC attachment. Route traffic only to the authorized VPCs.
