Question 4
A real estate company is building an internal application so that real estate agents can upload photos and videos of various properties. The application will store these photos and videos in an Amazon S3 bucket as objects and will use Amazon DynamoDB to store corresponding metadata. The S3 bucket will be configured to publish all PUT events for new object uploads to an Amazon Simple Queue Service (Amazon SQS) queue. A compute cluster of Amazon EC2 instances will poll the SQS queue to find out about newly uploaded objects. The cluster will retrieve new objects, perform proprietary image and video recognition and classification update metadata in DynamoDB and replace the objects with new watermarked objects. The company does not want public IP addresses on the EC2 instances. Which networking design solution will meet these requirements MOST cost-effectively as application usage increases?
A.
Place the EC2 instances in a public subnet. Disable the Auto-assign Public IP option while launching the EC2 instances. Create an internet gateway. Attach the internet gateway to the VPC. In the public subnet's route table, add a default route that points to the internet gateway.

Question 6
A company is using a shared services VPC with two domain controllers. The domain controllers are deployed in the company's private subnets. The company is deploying a new application into a new VPC in the account. The application will be deployed onto an Amazon EC2 for Windows Server instance in the new VPC. The instance must join the existing Windows domain that is supported by the domain controllers in the shared services VPC.
A transit gateway is attached to both the shared services VPC and the new VPC. The company has updated the route tables for the transit gateway, the shared services VPC, and the new VPC. The security groups for the domain controllers and the instance are updated and allow traffic only on the ports that are necessary for domain operations. The instance is unable to join the domain that is hosted on the domain controllers.
Which combination of actions will help identify the cause of this issue with the LEAST operational overhead? (Choose two.)
A.
Use AWS Network Manager to perform a route analysis for the transit gateway network. Specify the existing EC2 instance as the source. Specify the first domain controller as the destination. Repeat the route analysis for the second domain controller.
B.
Use port mirroring with the existing EC2 instance as the source and another EC2 instance as the target to obtain packet captures of the connection attempts.
C.
Review the VPC flow logs on the shared services VPC and the new VPC.
D.

Question 8
A company uses a hybrid architecture and has an AWS Direct Connect connection between its on-premises data center and AWS. The company has production applications that run in the on-premises data center. The company also has production applications that run in a VPC. The applications that run in the on-premises data center need to communicate with the applications that run in the VPC. The company is using corp.example.com as the domain name for the on-premises resources and is using an Amazon Route 53 private hosted zone for aws.example.com to host the VPC resources. The company is using an open-source recursive DNS resolver in a VPC subnet and is using a DNS resolver in the on-premises data center. The company's on-premises DNS resolver has a forwarder that directs requests for the aws.example.com domain name to the DNS resolver in the VPC. The DNS resolver in the VPC has a forwarder that directs requests for the corp.example.com domain name to the DNS resolver in the on-premises data center. The company has deckled to replace the open-source recursive DNS resolver with Amazon Route 53 Resolver endpoints. Which combination of steps should a network engineer take to make this replacement? (Choose three.)
A.
Create a Route 53 Resolver rule to forward aws.example.com domain queries to the IP addresses of the outbound endpoint.

Question 9
A network engineer is working on a private DNS design to integrate AWS workloads and on-premises resources. The AWS deployment consists of five VPCs in the eu-west-1 Region that connect to the on-premises network over AWS Direct Connect. The VPCs communicate with each other by using a transit gateway. Each VPC is associated with a private hosted zone that uses the aws.example.internal domain. The network engineer creates an Amazon Route 53 Resolver outbound endpoint in a shared services VPC and attaches the shared services VPC to the transit gateway.
The network engineer is implementing a solution for DNS resolution. Queries for hostnames that end with aws.example.internal must use the private hosted zone. Queries for hostnames that end with all other domains must be forwarded to a private on-premises DNS resolver.
Which solution will meet these requirements?
A.
Add a forwarding rule for * that targets the on-premises server's DNS IP address. Add a system rule for aws.example.internal that targets Route 53 Resolver.
B.
Add a forwarding rule for aws.example.internal that targets Route 53 Resolver. Add a system rule for . that targets the Route 53 Resolver outbound endpoint.
