A network engineer is working on a large migration effort from an on-premises data center to an AWS Control Tower based multi-account environment. The environment
has a transit gateway that is deployed to a central network services account. The central network services account has been shared with an organization in AWS
Organizations through AWS Resource Access Manager (AWS RAM).
A shared services account also exists in the environment. The shared services account hosts workloads that need to be shared with the entire organization.
The network engineer needs to create a solution to automate the deployment of common network components across the environment. The solution must provision a
VPC for application workloads to each new and existing member account. The VPCs must be connected to the transit gateway in the central network services account.
Which combination of steps will meet these requirements with the LEAST operational overhead? (Select THREE.)
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 networkengineer 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?
An ecommerce company needs to Implement additional security controls on all its domain names that are hosted in Amazon Route 53. The company's new policy requires data authentication and data integrity verification for all queries to the company's domain names. The current Route 53 architecture has four public hosted zones.
A network engineer needs to implement DNS Security Extensions (DNSSEC) signing and validation on the hosted zones. The solution must include an alert capability.
Which combination of steps will meet these requirements? {Select THREE.)
A company is using a NAT gateway to allow internet connectivity for private subnets in a VPC in the us-west-2 Region. After a security audit, the company needs to remove the NAT gateway.
In the private subnets, the company has resources that use the unified Amazon CloudWatch agent. A network engineer must create a solution to ensure that the unified CloudWatch agent continues to work after the removal of the NAT gateway.
Which combination of steps should the network engineer take to meet these requirements? (Choose three.)
A company has an application that runs on premises. The application needs to communicate with an application that runs in a VPC on AWS. The communication between the applications must be encrypted and must use private IP addresses. The communication cannot travel across the public internet.
The company has established a 1 Gbps AWS Direct Connect connection between the on-premises location and AWS.
Which solution will meet the connectivity requirements with the LEAST operational overhead?
A company has workloads that run in a VPC. The workloads access Amazon S3 by using an S3 gateway endpoint. The company also has on-premises workloads that need to access Amazon
S3 privately over a VPN connection. The company has established the VPN connection to the VPC.
Which solution will provide connectivity to Amazon S3 from the VPC workloads and the on-premises workloads in the MOST operationally efficient way?
A company has two business units (BUs). The company operates in the us-east-1 Region and the us-west-1 Region. The company plans to extend to more Regions in the future. Each BU has
a VPC in each Region. Each Region has a transit gateway with the BU VPCs attached. The transit gateways in both Regions are peered.
The company will create several more BUs in the future and will need to isolate some of the BUs from the other BUs. The company wants to migrate to an architecture to incorporate more
Regions and BUs.
Which solution will meet these requirements with the MOST operational efficiency?
