AWS Certified Advanced Networking- Specialty Questions and Answers

Question 25

A network engineer must develop an AWS CloudFormation template that can create a virtual private gateway, a customer gateway, a VPN connection, and static routes in a route table. During testing of the template, the network engineer notes that the CloudFormation template has encountered an error and is rolling back.

What should the network engineer do to resolve the error?

Options:

A.

Change the order of resource creation in the CloudFormation template.

B.

Add the DependsOn attribute to the resource declaration for the virtual private gateway. Specify the route table entry resource.

C.

Add a wait condition in the template to wait for the creation of the virtual private gateway.

D.

Add the DependsOn attribute to the resource declaration for the route table entry. Specify the virtual private gateway resource.

Question 26

A company's AWS architecture consists of several VPCs. The VPCs include a shared services VPC and several application VPCs. The company has established network connectivity from all VPCs to the on-premises DNS servers.

Applications that are deployed in the application VPCs must be able to resolve DNS for internally hosted domains on premises. The applications also must be able to resolve local VPC domain names and domains that are hosted in Amazon Route 53 private hosted zones.

What should a network engineer do to meet these requirements?

Options:

A.

Create a new Route 53 Resolver inbound endpoint in the shared services VPC. Create forwarding rules for the on-premises hosted domains. Associate the rules with the new Resolver endpoint and each application VPC. Update each application VPC's DHCP configuration to point DNS resolution to the new Resolver endpoint.

B.

Create a new Route 53 Resolver outbound endpoint in the shared services VPC. Create forwarding rules for the on-premises hosted domains. Associate the rules with the new Resolver endpoint and each application VPC.

C.

Create a new Route 53 Resolver outbound endpoint in the shared services VPCreate forwarding rules for the on-premises hosted domains. Associate the rules with the new Resolver endpoint and each application VPUpdate each application VPC's DHCP configuration to point DNS resolution to the new Resolver endpoint.

D.

Create a new Route 53 Resolver inbound endpoint in the shared services VPC. Create forwarding rules for the on-premises hosted domains. Associate the rules with the new Resolver endpoint and each application VPC.

Question 27

A company is deploying a non-web application on an AWS load balancer. All targets are servers located on-premises that can be accessed by using AWS Direct Connect. The company wants to ensure that the source IP addresses of clients connecting to the application are passed all the way to the end server.

How can this requirement be achieved?

Options:

A.

Use a Network Load Balancer to automatically preserve the source IP address.

B.

Use a Network Load Balancer and enable the X-Forwarded-For attribute.

C.

Use a Network Load Balancer and enable the ProxyProtocol v2 attribute.

D.

Use an Application Load Balancer to automatically preserve the source IP address in the X-Forwarded-For header.

Question 28

A network engineer needs to standardize a company's approach to centralizing and managing interface VPC endpoints for private communication with AWS services. The company uses AWS Transit Gateway for inter-VPC connectivity between AWS accounts through a hub-and-spoke model. The company's network services team must manage all Amazon Route 53 zones and interface endpoints within a shared services AWS account. The company wants to use this centralized model to provide AWS resources with access to AWS Key Management Service (AWS KMS) without sending traffic over the public internet.

What should the network engineer do to meet these requirements?

Options:

A.

In the shared services account, create an interface endpoint for AWS KMS. Modify the interface endpoint by disabling the private DNS name. Create a private hosted zone in the shared services account with an alias record that points to the interface endpoint. Associate the private hosted zone with the spoke VPCs in each AWS account.

B.

In the shared services account, create an interface endpoint for AWS KMS. Modify the interface endpoint by disabling the private DNS name. Create a private hosted zone in each spoke AWS account with an alias record that points to the interface endpoint. Associate each private hosted zone with the shared services AWS account.

C.

In each spoke AWS account, create an interface endpoint for AWS KMS. Modify each interface endpoint by disabling the private DNS name. Create a private hosted zone in each spoke AWS account with an alias record that points to each interface endpoint. Associate each private hosted zone with the shared services AWS account.

D.

In each spoke AWS account, create an interface endpoint for AWS KMS. Modify each interface endpoint by disabling the private DNS name. Create a private hosted zone in the shared services account with an alias record that points to each interface endpoint. Associate the private hosted zone with the spoke VPCs in each AWS account.
