Free Amazon ANS-C01 Exam Questions

Question 1

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 2

A global delivery company is modernizing its fleet management system. The company has several business units. Each business unit designs and maintains applications that are hosted in its own AWS account in separate application VPCs in the same AWS Region. Each business unit's applications are designed to get data from a central shared services VPC. The company wants the network connectivity architecture to provide granular security controls. The architecture also must be able to scale as more business units consume data from the central shared services VPC in the future. Which solution will meet these requirements in the MOST secure manner?

A : eate a central transit gateway. Create a VPC attachment to each application VPC. Provide full mesh connectivity between all the VPCs by using the transit gateway.

B : eate VPC peering connections between the central shared services VPC and each application VPC in each business unit's AWS account.

C : eate VPC endpoint services powered by AWS PrivateLink in the central shared services VPCreate VPC endpoints in each application VPC.

D : eate a central transit VPC with a VPN appliance from AWS Marketplace. Create a VPN attachment from each VPC to the transit VPC. Provide full mesh connectivity among all the VPCs.

Answer: C

Question 3

An analytics company uses Amazon QuickSight (Enterprise Edition) to easily create and publish interactive BI dashboards that can be accessed from any device. For a specific requirement, the company needs to create a private connection from Amazon QuickSight to an Amazon RDS DB instance that's in a private subnet to fetch data for analysis.

Which of the following represents an optimal solution for configuring a private connection between QuickSight and Amazon RDS DB instance?

A : Amazon QuickSight Enterprise edition is fully integrated with the Amazon VPC service. Create an ENI in QuickSight that points to the VPC that hosts the RDS DB instance. However, the subnet has to be a private subnet and not a public subnet

B : eate a new private subnet in the same VPC as the Amazon RDS DB instance. Create a new network Access Control List (ACL) with necessary inbound rules for QuickSight in the same VPC. Connect from QuckSight using VPC connector

C : Create a Private Virtual Interface between VPC that hosts Amazon RDS DB instance and QuickSight. Use this connection to privately access necessary data from RDS DB

D : eate a new private subnet in the same VPC as the Amazon RDS DB instance. Create a new security group with necessary inbound rules for QuickSight in the same VPC. Sign in to QuickSight as a QuickSight admin and create a new QuickSight VPC connection. Create a new dataset from the RDS DB instance

Answer: D

Question 5

A company has configured an AWS Cloud WAN core network with edge locations in the us-east-1 Region and the us-west-1 Region. Each edge location has two segments: development and staging. The segments use the default core network policy. The company has attached VPCs to the core network. A development VPC is attached to the development segment in us-east-1 and is configured to use the 10.0.0.0 CIDR block. A staging VPC is attached to the staging segment in us-west-1 and is configured to use the 10.5.0.0 CIDR block. The company has updated the route tables for both VPCs with a route that directs any traffic for 0.0.0.0/0 to the core network. The companys network team needs to establish communication between the two VPCs by using the AWS Cloud WAN core network. The network team is not receiving a response during tests of communication between the VPCs. The network team has verified that security groups and network ACLs are not blocking the traffic. What should the network team do to establish this communication?

A : Update both VPC route tables to have a new static route. Configure a route on the development VPC to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route on the staging VPC to direct the traffic for 10.5.0.0 to the staging VPC attachment.

B : Update the segment filter to allow traffic on the development and staging segments.

C : Set the isolate-attachments parameter to False for the development and staging segments.

D : Update the core network policy to add a static route for each segment. Configure a route to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route to direct the traffic for 10.5.0.0 to the staging VPC attachment.

Answer: D
