Free Amazon ANS-C01 Exam Questions

Question 1

A consulting company manages AWS accounts for its customers. One of the company's customers needs to add intrusion prevention for its environment without having to re-architect the environment. The customer's environment includes five VPCs in two AWS Regions in the United States. VPC-to-VPC connectivity is achieved through VPC peering. The customer does not plan to increase the number of VPCs within the next 2 years. The solution must accommodate unencrypted traffic. Which solution will meet these requirements?

A : Configure VPC security groups and network ACLs.

B : Use an AWS Network Firewall centralized deployment model in each VPC.

C : Use an AWS Network Firewall distributed deployment model in each VPC.

D : Deploy AWS Shield in each VPC.

Answer: C

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 multi-player gaming application that runs on UDP protocol needs to add functionality where you can assign multiple players to a single session on a game server based on factors such as geographic location, player skill, and few more configurable parameters. The application is accessed by players spread out across different regions of the world.

What is the right way to configure this requirement?

A : Application Load Balancer (ALB) with sticky sessions enabled to maintain player session data. Configure Global Accelerator to front the ALB for cross-region elasticity

B : custom routing accelerator of Global Accelerator to deterministically route one or more users to a specific instance using VPC subnet endpoints

C : Use custom routing accelerator of Global Accelerator in front of Network Load Balancer (NLB) to route traffic that can maintain session data

D : custom routing accelerator of Global Accelerator to deterministically route one or more users to a specific instance using VPC sharing

Answer: B

Question 4

An IoT company sells hardware sensor modules that periodically send out temperature, humidity, pressure, and location data through the MQTT messaging protocol. The hardware sensor modules send this data to the company's on-premises MQTT brokers that run on Linux servers behind a load balancer. The hardware sensor modules have been hardcoded with public IP addresses to reach the brokers. The company is growing and is acquiring customers across the world. The existing solution can no longer scale and is introducing additional latency because of the company's global presence. As a result, the company decides to migrate its entire infrastructure from on premises to the AWS Cloud. The company needs to migrate without reconfiguring the hardware sensor modules that are already deployed across the world. The solution also must minimize latency. The company migrates the MQTT brokers to run on Amazon EC2 instances. What should the company do next to meet these requirements?

A : ace the EC2 instances behind a Network Load Balancer (NLB). Configure TCP listeners. Use Bring Your Own IP (BYOIP) from the on-premises network with the NLB.

B : ace the EC2 instances behind a Network Load Balancer (NLB). Configure TCP listeners. Create an AWS Global Accelerator accelerator in front of the NLUse Bring Your Own IP (BYOIP) from the on-premises network with Global Accelerator.

C : ace the EC2 instances behind an Application Load Balancer (ALB). Configure TCP listeners. Create an AWS Global Accelerator accelerator in front of the ALB. Use Bring Your Own IP (BYOIP) from the on-premises network with Global Accelerator

D : ace the EC2 instances behind an Amazon CloudFront distribution. Use Bring Your Own IP (BYOIP) from the on-premises network with CloudFront.

Answer: B

Question 5

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
