Question 1

A company has set up hybrid connectivity between its VPCs and its on-premises data center. The company has the on-premises.example.com subdomain configured at its DNS server in the onpremises data center. The company is using the aws.example.com subdomain for workloads that run on AWS across different VPCs and accounts. Resources in both environments can access each other by using IP addresses. The company wants workloads in the VPCs to be able to access resources on premises by using the on-premises.example.com DNS names. Which solution will meet these requirements with MINIMUM management of resources?

A : Create an Amazon Route 53 Resolver outbound endpoint. Configure a Resolver rule that conditionally forwards DNS queries for on-premises.example.com to the on-premises DNS server. Associate the rule with the VPCs.

B : Create an Amazon Route 53 Resolver inbound endpoint and a Resolver outbound endpoint. Configure a Resolver rule that conditionally forwards DNS queries for on-premises.example.com to the on-premises DNS server. Associate the rule with the VPCs.

C : Launch an Amazon EC2 instance. Install and configure BIND software to conditionally forward DNS queries for on-premises.example.com to the on-premises DNS server. Configure the EC2 instance's IP address as a custom DNS server in each VPC.

D : Launch an Amazon EC2 instance in each VPC. Install and configure BIND software to conditionally forward DNS queries for on-premises.example.com to the on-premises DNS server. Configure the EC2 instance's IP address as a custom DNS server in each VPC.

Answer: A

Question 2

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 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 4

Company A recently acquired Company B. Company A has a hybrid AWS and on-premises environment that uses a hosted AWS Direct Connect connection, a Direct Connect gateway, and a transit gateway. Company A has a transit VIF to access the resources in its production environment in the us-east-1 Region. Company B has applications that run across multiple VPCs in the us-west-2 Region in a single AWS account. A transit gateway connects all Company B's application VPCs. The CIDR blocks for both companies do not overlap. Company A needs to use the existing Direct Connect connection to access Company Bs applications from the on-premises environment. Which solution will meet these requirements?

A : Create a new Direct Connect gateway in the Company B account. Associate the Company B transit gateway with the new Direct Connect gateway. Create a transit VIF on the existing hosted connection for Company B.

B : Create an association proposal from the Company B account to associate the Company B transit gateway with the Company A Direct Connect gateway. Accept the transit gateway association proposal by logging into the Company A account.

C : Create multiple virtual private gateways. Attach the virtual private gateways to each of Company B's application VPCs. Create a hosted private VIF for each virtual private gateway.

D : Create a new Direct Connect gateway in the Company B account. Associate the Company B transit gateway with the new Direct Connect gateway. Create a hosted private VIF for Company B.

Answer: B

Question 5

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.

Answer: C
