Free Amazon ANS-C01 Exam Questions

Question 1

A company has an on-premises data center in the United States. The data center is connected to AWS by an AWS Direct Connect connection. The data center has a private VIF that is connected to a Direct Connect gateway. Recently, the company opened a new data center in Europe and established a new Direct Connect connection between the Europe data center and AWS. A new private VIF connects to the existing Direct Connect gateway. The company wants to use Direct Connect SiteLink to set up a private network between the data center in the United States and the data center in Europe. Which solution will meet these requirements in the MOST operationally efficient manner?

A : Create a new public VIF from each data center. Enable SiteLink on the new public VIFs.

B : Create a new transit VIF from each data center. Enable SiteLink on the new transit VIFs.

C : Use the existing VIF from each data center. Enable SiteLink on the existing private VIFs.

D : Create a new AWS Site-to-Site VPN connection between the data centers. Configure the new connection to use SiteLink.

Answer: C

Question 2

A company is planning to migrate to AWS and use multiple VPCs in multiple AWS Regions. A network engineer must connect the eu-west-1 and eu-central-1 Regions to the company headquarters and branch office, respectively. The network engineer created a production VPC, named Prod A, with a CIDR block of 10.0.0.0. Prod A runs in an account in eu-west-1. The network engineer then created another production VPC, named Prod B, with a CIDR block of 10.1.0.0. Prod Ð’ runs in a different account in eu-central-1. The network engineer performed the following steps to try to achieve the required connectivity: 1. Created one transit gateway in each Region2. Shared and accepted the transit gateways with the production accounts in both Regions3. Configured the peering attachment between both transit gateways4. Attached both VPCs to the respective Region transit gateway5. Created both transit gateway route tables and associated the attachments with the route tables6. Configured a static route in both transit gateway route tables to send traffic to the remote VPC in the other Region7. Activated route propagation on the VPC route tables in each Region After the configuration, the network engineer tried to connect from Prod A to Prod B. However, the connection was unsuccessful. What should the network engineer do to achieve the required connectivity?

A : Modify the IP address of the peering attachment to a wider range.

B : Delete the static routes that were in the transit gateway route table to send traffic to the remote VPC and enable route propagation instead.

C : Create a new route destined to 10.0.0.0 in both production VPC route tables with the Region transit gateway as the target.

D : Modify the transit gateway route tables from the production accounts to propagate routes dynamically between the production VPCs.

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 : ace 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.

B : ace the EC2 instances in a private subnet. Create a NAT gateway in a public subnet in the same Availability Zone. 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

C : ace the EC2 instances in a private subnet. Create an interface VPC endpoint for Amazon SQS. Create gateway VPC endpoints for Amazon S3 and DynamoDB.

D : ace the EC2 instances in a private subnet. Create a gateway VPC endpoint for Amazon SQS.Create interface VPC endpoints for Amazon S3 and DynamoDB.

Answer: C

Question 5

A company uses AWS Network Firewall to protect outgoing traffic for multiple VPCs that are in the same AWS account. Each VPC contains Amazon EC2 instances that host the company's applications. Each EC2 instance is tagged with the name of the application it hosts. The EC2 instances are in Auto Scaling groups. A Network Firewall stateful rule group must remain up-to-date, even when an Auto Scaling group launches and terminates EC2 instances. Which solution will meet this requirement with the LEAST implementation and administrative effort?

A : Create a network ACL for each application. Reference the network ACL in the stateful rule group.

B : Create a prefix list for each application. Reference the prefix list in the stateful rule group.

C : Create an AWS Lambda function that queries the EC2 instance tags for each application name and then updates the stateful rule group with the IP address of each instance.

D : Create a resource group for each application name. Reference the Amazon Resource Name (ARN) for the resource groups in the stateful rule group.

Answer: B
