Question 17

A company with several VPCs in the us-east-1 Region wants to reduce the cost of its workloads A network engineer has identified that all traffic bound to Amazon services is flowing through a NAT gateway. Additionally, all the VPCs are peered to a hub VPC for access to common services.

Options:

A.

Disable the private DNS name for the SQS endpoint. Create an Amazon Route 53 private hosted zone for the domain us-east-1.sqs.amazonaws.com. Create a CNAME record to the DNS name of the SQS endpoint Share the private hosted zone with ail other VPCs

B.

Disable the private DNS name for the SOS endpoint. Create an Amazon Route 53 private hosted zone for the domain sqs.us-east-1 .amazonaws.com. Create an alias record to the DNS name of the SOS endpoint. Share the private hosted zone with all other VPCs

C.

Enable the private DNS name for the SOS endpoint Create an Amazon Route 53 private hosted zone for the domain SQS.us-east-t.amazonaws.com. Create a CNAME record to the DNS name of the SQS endpoint. Share the private hosted zone with all other VPCs.

D.

Enable the private DNS name for the SQS endpoint. Create an Amazon Route 53 private hosted zone for the domain us-east-1 .sqs.amazonaws.com. Create an alias record to the DNS name of the SQS endpoint. Share the private hosted zone with all other VPCs.

Question 18

A company has a hybrid environment across its on-premises network and the AWS Cloud The company wants to use Amazon Elastic File System (Amazon EFS) to store and share data between on-premises services that are required to resolve DNS queries through on-premises DNS servers The company wants to use a custom domain name to connect to Amazon EFS The company also wants to avoid using the Amazon EFS target IP address.

What should a network engineer do to meet these requirements?

Options:

A.

Create an Amazon Route 53 Resolver outbound endpoint and configure it for the VPC where Amazon EFS resides Create a Route 53 public hosted zone, and add a new CNAME record with the value of the Amazon EFS DNS name Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 public hosted zone

B.

Create an Amazon Route 53 Resolver inbound endpoint and configure it for the VPC where Amazon EFS resides Create a Route 53 private hosted zone, and add a new CNAME record with the value of the Amazon EFS DNS name Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 Resolver

C.

Create an Amazon Route 53 Resolver outbound endpoint and configure it for the VPC where Amazon EFS resides Create a Route 53 private hosted zone,

and add a new CNAME record with the value of the Amazon EFS DNS name Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 Resolver

D.

Create an Amazon Route 53 Resolver inbound endpoint and configure it for the VPC where Amazon EFS resides Create a Route 53 private hosted zone, and add a new PTR record with the value of the Amazon EFS DNS name Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 private hosted zone

Question 19

A company is using AWS to host all of its applications. Each application is isolated in its own Amazon VPC. Different environments such as Development, Test, and Production are also isolated in their own VPCs. The Network Engineer needs to automate VPC creation to enforce the company’s network and security standards. Additionally, the CIDR range used in each VPC needs to be unique.

Which solution meets all of these requirements?

Options:

A.

Use AWS CloudFormation to deploy the VPC infrastructure and a custom resource to request a CIDR range from an external IP address management (IPAM) service.

B.

Use AWS OpsWorks to deploy the VPC infrastructure and a custom resource to request a CIDR range from an external IP address management (IPAM) service.

C.

Use the VPC wizard in the AWS Management Console. Type in the CIDR blocks for the VPC and subnets.

D.

Create the VPCs using AWS CLI and use the dry-run flag to validate if the current CIDR range is in use.

Question 20

You are deploying an EC2 instance in a private subnet that requires access to the Internet. One of the requirements for this solution is to restrict access to only particular URLs on a whitelist. In addition to the whitelisted URL, the instances should be able to access any Amazon S3 bucket in the same region via any URL.

Which of the following solutions should you deploy? (Select two.)

Options:

A.

Include s3.amazonaws.com in the whitelist.

B.

Create a VPC endpoint for S3.

C.

Run Squid proxy on a NAT instance.

D.

Deploy a NAT gateway into your VPC.

E.
