Free Amazon ANS-C01 Exam Questions

Question 1

A company uses AWS Direct Connect to connect its corporate network to multiple VPCs in the same AWS account and the same AWS Region. Each VPC uses its own private VIF and its own virtual LAN on the Direct Connect connection. The company has grown and will soon surpass the limit of VPCs and private VIFs for each connection. What is the MOST scalable way to add VPCs with on-premises connectivity?

A : ovision a new Direct Connect connection to handle the additional VPCs. Use the new connection to connect additional VPCs.

B : eate virtual private gateways for each VPC that is over the service quota. Use AWS Site-to-Site VPN to connect the virtual private gateways to the corporate network.

C : eate a Direct Connect gateway, and add virtual private gateway associations to the VPCs. Configure a private VIF to connect to the corporate network.

D : eate a transit gateway, and attach the VPCs. Create a Direct Connect gateway, and associate it with the transit gateway. Create a transit VIF to the Direct Connect gateway.

Answer: D

Question 2

A company runs workloads in multiple VPCs. The company needs to securely access a workload in one of the VPCs, named VPC-A, from an on-premises data center. A network engineer sets up an AWS Site-to-Site VPN connection to a transit gateway. The network engineer configures dynamic routing for the connection, and communication works properly. Recently, the owner of VPC-A added another CIDR range to the VPC. The VPC-A owner created workloads that use the additional CIDR range. The company's on-premises network is unable to reach the new workloads. The network engineer needs to resolve the network connectivity issue and ensure that connectivity will not be affected if additional VPC CIDR ranges are added to the VPC in the future. Which solution will meet these requirements with the MOST operational efficiency?

A : Configure route propagation for VPC-A to the VPN attachment route table.

B : Manually update the VPN attachment route table to include the new CIDR range.

C : Configure an Amazon EventBridge rule to invoke an AWS Lambda function when the rule to matches an update to the VPC-A CIDR range. Configure the Lambda function to update the VPN attachment route table.

D : Configure an Amazon CloudWatch alarm to invoke an AWS Lambda function when there is an update to the VPC-A CIDR range. Configure the Lambda function to update the VPN attachment route table. Restart the VPN tunnels.

Answer: A

Question 3

A network engineer needs to build an encrypted connection between an on-premises data center and a VPC. The network engineer attaches the VPC to a virtual private gateway and sets up an AWS Site-to-Site VPN connection. The VPN tunnel is UP after configuration and is working. However, during rekey for phase 2 of the VPN negotiation, the customer gateway device is receiving different parameters than the parameters that the device is configured to support. The network engineer checks the IPsec configuration of the VPN tunnel. The network engineer notices that the customer gateway device is configured with the most secure encryption algorithms that the AWS Site-to-Site VPN configuration file provides. What should the network engineer do to troubleshoot and correct the issue?

A : Check the native virtual private gateway logs. Restrict the VPN tunnel options to the specific VPN parameters that the virtual private gateway requires.

B : Check the native customer gateway logs. Restrict the VPN tunnel options to the specific VPN parameters that the customer gateway requires.

C : Check Amazon CloudWatch logs of the virtual private gateway. Restrict the VPN tunnel options to the specific VPN parameters that the virtual private gateway requires.

D : Check Amazon CloudWatch logs of the customer gateway. Restrict the VPN tunnel options to the specific VPN parameters that the customer gateway requires.

Answer: B

Question 4

A company hosts a web application that runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group. The company uses an Amazon CloudFront distribution with the ALB as an origin. The application recently experienced an attack. In response, the company associated an AWS WAF web ACL with the CloudFront distribution. The company needs to use Amazon Athena to analyze application attacks that AWS WAF detects. Which solution will meet this requirement?

A : Configure the ALB and the EC2 instance subnets to produce VPC flow logs. Configure the VPC flow logs to deliver logs to an Amazon S3 bucket for log analysis.

B : Create a trail in AWS CloudTrail to capture data events. Configure the trail to deliver logs to an Amazon S3 bucket for log analysis.

C : Configure the AWS WAF web ACL to deliver logs to an Amazon Kinesis Data Firehose delivery stream. Configure the stream to deliver the data to an Amazon S3 bucket for log analysis.

D : Turn on access logging for the ALB. Configure the access logs to deliver the logs to an Amazon S3 bucket for log analysis.

Answer: D

Question 5

A Network Engineer needs to create a public virtual interface on the company's AWS Direct Connect connection and only import routes which originated from the same region as the Direct Connect location.

What action should accomplish this?

A : nfigure a prefix list on the customer router containing the AWS IP address ranges for the specific region.

B : nfigure a filter on the company's router to only import routes with the 7224:8100 BGP community attribute.

C : nfigure a filter on the company's router to only import routes without a BGP community attribute and a maximum path length of 3.

D : nfigure a filter in the console and only allow routes advertised by AWS without a BGP community attribute and a maximum path length of 3.

Answer: B
