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 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 3

A company has developed a web service for language translation. The web service's application runs on a fleet of Amazon EC2 instances that are in an Auto Scaling group. The instances run behind an Application Load Balancer (ALB) and are deployed in a private subnet. The web service can process requests that contain hundreds of megabytes of data. The company needs to give some customers the ability to access the web service. Each customer has its own AWS account. The company must make the web service accessible to approved customers without making the web service accessible to all customers. Which combination of steps will meet these requirements with the LEAST operational overhead? (Choose two.)

A : Create VPC peering connections with the approved customers only.

B : Create an AWS PrivateLink endpoint service. Configure the endpoint service to require acceptance that will be granted to approved customers only.

C : Configure an authentication action for the endpoint service's load balancer to allow customers to log in by using their AWS credentials. Provide only approved customers with the URL.

D : Configure a Network Load Balancer (NLB) and a listener with the ALB as a target. Associate the NLB with the endpoint service.

E : Associate the ALB with the endpoint service.

Answer: B,D

Question 4

A company deployed an application in two AWS Regions in one AWS account. The company has one VPC in each Region. The VPCs use non-overlapping private CIDR ranges. The company needs to connect both VPCs to a single on-premises data center to test the application. The application requires up to 800 Mbps of throughput. A network engineer needs to establish connectivity between the VPCs and the on-premises data center. Which solution will meet this requirement with the LEAST operational overhead?

A : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure static routes in the VPC route tables and in the data center router.

B : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure Open Shortest Path First (OSPF) routing between the private VIF and the data center.

C : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure static routes in each VPC route table to point to the subnets in the data center.

D : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure BGP routing between the VPCs and the data center.

Answer: A

Question 5

A company wants to analyze TCP internet traffic. The traffic originates from Amazon EC2 instances in the companys VPC. The EC2 instances initiate connections through a NAT gateway. The company wants to capture data about the traffic including source and destination IP addresses ports, and the first 8 bytes of the TCP segments of the traffic. The company needs to collect, store, and analyze all the required data points. Which solution will meet these requirements?

A : Configure the EC2 instances to be VPC traffic mirror sources. Deploy software on the traffic mirror target to forward the data to Amazon CloudWatch Logs. Analyze the data by using CloudWatch Logs Insights

B : Configure the NAT gateway to be a VPC traffic mirror source. Deploy software on the traffic mirror target to forward the data to an Amazon S3 bucket. Analyze the data by using Amazon Athena.

C : Turn on VPC Flow Logs for the EC2 instances. Specify the default format and set Amazon CloudWatch Logs as the log destination. Analyze the flow log data by using CloudWatch Logs Insights.

D : Turn on VPC Flow Logs for the EC2 instances. Specify a custom format and set Amazon S3 as the log destination. Analyze the flow log data by using Amazon Athena.

Answer: A
