NEW QUESTION # 42
A development team is building an application that will use an Amazon API Gateway REST API and AWS Lambda functions to receive and process requests. The Lambda functions will deliver messages to an Amazon SNS topic. External stakeholders subscribe to the SNS topic.
The company wants to prevent sensitive data from being published to the SNS topic.
Which solution will meet these requirements?
Answer: A
Explanation:
Amazon SNS data protection policies can inspect message payloads for sensitive data using configured data identifiers and apply protective actions such as blocking or de-identifying matching content. This prevents sensitive information from being published to subscribers while keeping the protection directly associated with the SNS topic.
NEW QUESTION # 43
A company's developers manually install software modules on Amazon EC2 instances to deploy new versions of a service. A security audit finds that instances contain inconsistent and unapproved modules.
A CloudOps engineer must create a new instance image that contains only approved software.
Which solution will meet these requirements?
Answer: C
Explanation:
According to the AWS Cloud Operations and Deployment documentation, EC2 Image Builder is the AWS-managed service for automating the creation, maintenance, validation, and deployment of secure and compliant Amazon Machine Images (AMIs).
It allows CloudOps teams to define image pipelines that include only approved software modules and configuration scripts. EC2 Image Builder automatically tests and verifies these AMIs for compliance before deployment.
This process ensures configuration consistency, eliminates manual installation errors, and simplifies ongoing patch management. The service integrates with AWS Systems Manager, Amazon Inspector, and AWS CloudFormation for end-to-end automation.
Amazon Detective and GuardDuty (Options A & B) are security monitoring tools, not image management solutions.
Run Command (Option C) applies ad-hoc updates but does not create standard, reusable AMIs.
Therefore, Option D is correct--EC2 Image Builder provides the most operationally efficient and compliant way to create an approved baseline AMI for future deployments.
NEW QUESTION # 44
A company deploys non-production Amazon EC2 instances in a VPC that has an internet gateway attached. The VPC has a single public subnet and a single private subnet. The EC2 instances in the private subnet cannot communicate outbound to the internet. Which action will give the EC2 instances in the private subnet the ability to communicate outbound to the internet?
Answer: A
Explanation:
Instances in a private subnet do not have direct internet-routable access, even if the VPC has an internet gateway. To allow outbound internet access while preventing inbound internet-initiated access, deploy a NAT gateway in a public subnet and route the private subnet's default route,
0.0.0.0/0, to that NAT gateway. The NAT gateway then uses the public subnet's route to the internet gateway. Option A is wrong because NAT gateways must be placed in public subnets to reach the internet. Option C would require the instances to have public IP addresses and would make the subnet effectively public, which violates the private subnet model. Option D is invalid because a VPC can have only one internet gateway attached, and internet gateways are attached to VPCs, not individual subnets.
NEW QUESTION # 45
A company runs a web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The company needs an AWS Lambda function to perform a custom recovery procedure on the application server when the application returns an HTTP 500 status code. A CloudOps engineer needs to design a solution that detects HTTP 500 status codes and runs the Lambda function reliably when errors are detected. Which solution will meet these requirements?
Answer: D
Explanation:
The ALB target group metric HTTPCode_Target_5XX_Count records HTTP 5XX responses generated by targets behind the load balancer. A CloudWatch alarm can monitor this metric and enter the ALARM state when the error count crosses the defined threshold. CloudWatch alarms can directly invoke a Lambda function as an alarm action, which makes this the simplest reliable automation path for custom recovery. AWS documentation states that invoking a Lambda function is an alarm action and is used to automate custom actions on alarm state changes.
Option B uses log polling, which adds latency and operational overhead. CloudTrail does not capture application HTTP 500 responses from EC2 instances. EventBridge does not receive every ALB request as an event. Therefore, CloudWatch alarm plus Lambda action is correct.
NEW QUESTION # 46
A company asks a SysOps administrator to provision an additional environment for an application in four additional AWS Regions. The application is running on more than 100 Amazon EC2 instances in the us-east-
1 Region, using fully configured Amazon Machine Images (AMIs). The company has an AWS CloudFormation template to deploy resources in us-east-1.
What should the SysOps administrator do to provision the application in the MOST operationally efficient manner?
Answer: B
