Question 28

A company is deploying AWS Cloud WAN with edge locations in the us-east-1 Region and the ap-southeast-2 Region. Individual AWS Cloud WAN segments are configured for the development environment, the production environment, and the shared services environment at each edge location. Many new VPCs will be deployed for the environments and will be configured as attachments to the AWS Cloud WAN core network.

The company's network team wants to ensure that VPC attachments are configured for the correct segment. The network team will tag the VPC attachments by using the Environment key with a value of the corresponding environment segment name. The segment for the production environment in us-east-1 must require acceptance for attachment requests. AH other attachment requests must not require acceptance.

Which solution will meet these requirements?

Options:

Create a rule with a number of 100 that requires acceptance for attachments to the production segment. In the rule, set the condition logic to the "or" value. Include conditions that require a tag:Environment value of Production or a Region value of us-east-1. Create a rule with a number of 200 that does not require acceptance to map any tag:Environment values to their respective segments.

Create a rule with a number of 100 that requires acceptance for attachments to the production segment. In the rule, set the condition logic to the "and" value. Include conditions that require a tag:Environment value of Production and a Region value of us-east-1. Create a rule with a number of 200 that does not require acceptance to map any tag:Environment values to their respective segments.

Question 29

A company has a VPC in the AWS Cloud. The company recently acquired a competitor that also has a VPC in the AWS Cloud. A network engineer discovers an IP address overlap between the two VPCs. Both VPCs require access to an AWS Marketplace partner service.

Which solution will ensure interoperability among the VPC hosted services and the AWS Marketplace partner service?

Options:

Configure VPC peering with static routing between the VPCs. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.

Configure a NAT gateway in the VPCs. Configure default routes in each VPC to point to the local NAT gateway. Attach each NAT gateway to a transit gateway. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.

Configure AWS PrivateLink to facilitate connectivity between the VPCs and the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.

Configure a NAT instance in the VPCs. Configure default routes in each VPC to point to the local NAT instance. Configure an interface endpoint in each VPC to connect to the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.

Question 30

A company has workloads that run in a VPC. The workloads access Amazon S3 by using an S3 gateway endpoint. The company also has on-premises workloads that need to access Amazon

S3 privately over a VPN connection. The company has established the VPN connection to the VPC.

Which solution will provide connectivity to Amazon S3 from the VPC workloads and the on-premises workloads in the MOST operationally efficient way?

Options:

Deploy a proxy fleet of Amazon EC2 instances in the VPC behind an Application Load Balancer (ALB). Configure the on-premises workloads to use the ALB as the proxy server to connect to Amazon S3. Configure the proxy fleet to use the S3 gateway endpoint to connect to Amazon S3.

Delete the S3 gateway endpoint. Create an S3 interface endpoint. Deploy a proxy fleet of Amazon EC2 instances in the VPC behind an Application Load Balancer (ALB).

Configure the on-premises workloads to use the ALB as the proxy server to connect to Amazon S3. Configure the proxy fleet and the VPC workloads to use the S3 interface

endpoint to connect to Amazon S3.

Create an S3 interface endpoint. Configure an on-premises DNS resolver to resolve the S3 DNS names to the private IP addresses of the S3 interface endpoint. Use the S3

interface endpoint to access Amazon S3. Continue to use the S3 gateway endpoint for the VPC workloads to access Amazon S3.

Set up an AWS Direct Connect connection. Create a public VIF. Configure on-premises routing to route the S3 traffic over the public VIF. Make no changes to the on-premises

workloads. Continue to use the S3 gateway endpoint for the VPC workloads to access Amazon S3.

Question 31

A company has two on-premises data center locations. There is a company-managed router at each data center. Each data center has a dedicated AWS Direct Connect connection to a Direct Connect gateway through a private virtual interface. The router for the first location is advertising 110 routes to the Direct Connect gateway by using BGP, and the router for the second location is advertising 60 routes to the Direct Connect gateway by using BGP. The Direct Connect gateway is attached to a company VPC through a virtual private gateway.

A network engineer receives reports that resources in the VPC are not reachable from various locations in either data center. The network engineer checks the VPC route table and sees that the routes from the first data center location are not being populated into the route table. The network engineer must resolve this issue in the most operationally efficient manner.

What should the network engineer do to meet these requirements?
