A banking company has an application that must connect to specific public IP addresses from a VPC. A network engineer has configured routes in the route table that is associated with the application's subnet to the required public IP addresses through an internet gateway.
The network engineer needs to set up email notifications that will alert the network engineer when a user adds a default route to the application subnet's route table with the internet gateway as a target.
Which solution will meet these requirements with the LEAST implementation effort?

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.

A company uses the us-east-1 Region and the ap-south-1 Region for its business units (BUs). The BUs are named BU-1 and BU-2. For each BU. there are two VPCs in us-east-1 and one VPC in ap-south-1.
Because of workload isolation requirements, resources can communicate within the same BU but cannot communicate with resources in the other BU. The company plans to add more BUs and plans to expand into more Regions.
Which solution will meet these requirements with the MOST operational efficiency?

A company's network engineer must implement a cloud-based networking environment for a network operations team to centrally manage. Other teams will use the environment. Each team must be able to deploy infrastructure to the environment and must be able to manage its own resources. The environment must feature IPv4 and IPv6 support and must provide internet connectivity in a dual-stack configuration.
The company has an organization in AWS Organizations that contains a workload account for the teams. The network engineer creates a new networking account in the organization.

A network engineer is working on a private DNS design to integrate AWS workloads and on-premises resources. The AWS deployment consists of five VPCs in the eu-west-1 Region that connect to the on-premises network over AWS Direct Connect. The VPCs communicate with each other by using a transit gateway. Each VPC is associated with a private hosted zone that uses the aws.example.internal domain. The network engineer creates an Amazon Route 53 Resolver outbound endpoint in a shared services VPC and attaches the shared services VPC to the transit gateway.
The network engineer is implementing a solution for DNS resolution. Queries for hostnames that end with aws.example.internal must use the private hosted zone. Queries for hostnames that end with all other domains must be forwarded to a private on-premises DNS resolver.
Which solution will meet these requirements?
Question 137

A company is migrating its on-premises network from its data center in Virginia to its data center in New York. The AWS Direct Connect connections for the Virginia and New York data center locations are both associated to the us-east-1 Region. The company needs to migrate a private VIF on an existing Direct Connect hosted connection from Virginia to New York. The company's on-premises network uses the connection to access VPCs through a Direct Connect gateway in us-east-1.
The company has already requested a new Direct Connect hosted connection from the new data center to the New York Direct Connect location.
Which solution will meet these requirements with the LEAST downtime?
Question 138

A company runs an application on Amazon EC2 instances. A network engineer implements a NAT gateway in the application's VPC to replace self-managed NAT instances. After the network engineer shifts traffic from the self-managed NAT instances to the NAT gateway, users begin to report issues.
During troubleshooting, the network engineer discovers that the connection to the application is closing after approximately 6 minutes of inactivity.
What should the network engineer do to resolve this issue?
Question 139
![Export Export](https://examgecko.com/assets/images/icon-download-24.png)
A network engineer needs to improve the network security of an existing AWS environment by adding an AWS Network Firewall firewall to control internet-bound traffic. The AWS environment consists of five VPCs. Each VPC has an internet gateway. NAT gateways, public Application Load Balancers (ALBs), and Amazon EC2 instances. The EC2 instances are deployed in private subnets. The architecture is deployed across two Availability Zones.
The network engineer must be able to configure rules for the public IP addresses in the environment, regardless of the direction of traffic. The network engineer must add the firewall by implementing a solution that minimizes changes to the existing production environment. The solution also must ensure high availability.
Which combination of steps should the network engineer take to meet these requirements? (Select TWO)
Question 140
![Export Export](https://examgecko.com/assets/images/icon-download-24.png)
A company has deployed a multi-VPC environment in the AWS Cloud. The company uses a transit gateway to connect all the VPCs together. In the past, the company has experienced a loss of connectivity between applications after changes to security groups, network ACLs. and route tables in a VPC. When these changes occur, the company wants to automatically verify that connectivity still exists between different resources in a single VPC.
Which solution will meet these requirements?
