Question 31 (Topic 1)

A company has a hybrid environment. The company has set up an AWS Direct Connect connection between the company's on-premises data center and a workload that runs in a VPC. The company uses Amazon Route 53 for DNS on AWS. The company uses a private hosted zone to manage DNS names for a set of services that are hosted on AWS. The company wants the on-premises servers to use Route 53 for DNS resolution of the private hosted zone. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Create a Route 53 inbound endpoint. Ensure that security groups and routing allow the traffic from the on-premises data center. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone's domain name to the IP addresses of the inbound endpoint.
  • ○ Create a Route 53 outbound endpoint. Ensure that security groups and routing allow the traffic from the VPC. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone’s domain name to the IP addresses of the outbound endpoint.
  • ○ Edit the private hosted zone in Route 53 with a TXT record that references the on-premises DNS servers. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone’s domain name to the base of the VPC CIDR IPv4 network range, plus two.
  • ○ Edit the private hosted zone in Route 53 with a PTR record that references the on-premises DNS servers. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone’s domain name to the base of the VPC CIDR IPv4 network range, plus two.
Question 32 (Topic 1)

A company runs an application on hundreds of Amazon EC2 instances in three Availability Zones. The application calls a third-party API over the public internet. A SysOps administrator must provide the third party with a list of static IP addresses so that the third party can allow traffic from the application. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Add a NAT gateway in the public subnet of each Availability Zone. Make the NAT gateway the default route of all private subnets in those Availability Zones.
  • ○ Allocate one Elastic IP address in each Availability Zone. Associate the Elastic IP address with all the instances in the Availability Zone.
  • ○ Place the instances behind a Network Load Balancer (NLB). Send the traffic to the internet through the private IP address of the NLB.
  • ○ Update the main route table to send the traffic to the internet through an Elastic IP address that is assigned to each instance.
Question 33 (Topic 1)

A company decides to stop non-production Amazon EC2 instances during the EC2 instances. The company's IT manager must receive notification in near real time whenever an EC2 instance that has an environment type tag value of non-production is started during the night. Which solution will meet this requirement with the MOST operational efficiency?

Select an option, then click Submit answer.

  • ○ Configure an AWS Lambda function with an SMTP client library. Subscribe the Lambda function to the AWS Health Dashboard to receive notification whenever an EC2 instance is in the running state. Configure the Lambda function to use Amazon Pinpoint to send email notifications to the IT manager. Deploy a second Lambda function to throttle calls from the first Lambda function during the daytime.
  • ○ Deploy an AWS Lambda function that queries the Amazon EC2 API to determine the state of each EC2 instance. Use the EC2 instance scheduler to configure the Lambda function to run every minute during the night and to send an email notification to the IT manager for each non-production EC2 instance that is in the running state.
  • ○ Create an Amazon EventBridge rule that includes the EC2 Instance State-change Notification event type. Filter the event to capture only the running state. Create an AWS Lambda function as a target of the rule. Configure the Lambda function to check the current time and the EC2 instances’ tags to determine the environment type. Create an Amazon Simple Notification Service (Amazon SNS) topic as a target of the Lambda function for notifications. Subscribe the IT manager's email address to the SNS topic.
  • ○ Store the EC2 instance metadata, including the environment type, in an Amazon DynamoDB table. Deploy a custom application to an EC2 instance. Configure the custom application to poll the DynamoDB data every minute during the night and to query the Amazon EC2 API to determine the state of each instance. Additionally, configure the custom application to send an email notification to the IT manager for each non-production EC2 instance that is in the running state.
