Question # 41

A company is planning to host external websites on AWS. The websites will include multiple tiers such as web servers, application logic services, and databases. The company wants to use AWS Network Firewall. AWS WAR and VPC security groups for network security.

The company must ensure that the Network Firewall firewalls are deployed appropriately within relevant VPCs. The company needs the ability to centrally manage policies that are deployed to Network Firewall and AWS WAF rules. The company also needs to allow application teams to manage their own security groups while ensuring that the security groups do not allow overly permissive access.

What is the MOST operationally efficient solution that meets these requirements?

Define Network Firewall firewalls. AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups in code Use AWS CloudFormation to deploy the objects and Initial policies and rule groups. Use CloudFormation to update the AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups. Use Amazon GuardDuty to monitor for overly permissive rules.

Define Network Firewall firewalls. AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups in code. Use the AWS Management Console or the AWS CLI to manage the AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups. Use Amazon GuardDuty to invoke an AWS Lambda function to evaluate the configured rules and remove any overly permissive rules.

Deploy AWS WAFv2 IP sets and AWS WAFv2 web ACLs with AWS CloudFormation. Use AWS Firewall Manager to deploy Network Firewall firewalls and VPC security groups where required and to manage the AWS WAFv2 web ACLs, Network Firewall policies, and VPC security groups.

Question # 42

A bank built a new version of its banking application in AWS using containers that content to an on-premises database over VPN connection. This application version requires users to also update their client application. The bank plans to deprecate the earlier client version. However, the company wants to keep supporting earlier clients through their on-premises version of the application to serve a small portion of the customers who havenâ€™t yet upgraded.

What design will allow the company to serve both newer and earlier clients in the MOST efficient way?

Use an Amazon Route 53 multivalue answer routing policy to route older client traffic to the on-premises application version and the rest of the traffic to the new AWS based version.

Use a Classic Load Balancer for the new application. Route all traffic to the new application by using an Elastic Load Balancing (ELB) load balancer DNS. Define a user-agent-based rule on the backend servers to redirect earlier clients to the on-premises application.

Use an Application Load Balancer for the new application. Register both the new and earlier applications as separate target groups and use path-based routing to route traffic based on the application version.

Use an Application Load Balancer for the new application. Register both the new and earlier application backends as separate target groups. Use header-based routing to route traffic based on the application version.

Question # 43

A company is replatforming a legacy data processing solution to AWS. The company deploys the solution on Amazon EC2 Instances in private subnets that are in one VPC.

The solution uses Amazon S3 for abject storage. Both the data that the solution processes and the data the solution produces are stored in Amazon S3. The solution uses Amazon DynamoDB to save its own state. The company collects flow logs for the VPC. Thesolution uses one NAT gateway to register its license through the internet. A software vendor provides a specific hostname so the solution can register its license.

The company notices that the AWS bill exceeds the projected budget for the solution. A network engineer uses AWS Cost Explorer to investigate the bill. The network engineer notices that the USE2-NatGateway-Bytes($) usage type is the root cause of the higher than expected bill.

What should the network engineer do to resolve the issue? (Choose two.)

Set up Amazon VPC Traffic Mirroring. Analyze the traffic to identify the traffic that the NAT gateway processes.

Examine the VPC flow logs to identity the traffic that traverses the NAT gateway.

Set up an AWS Cost and Usage Report in the AWS Billing and Cost Management console. Examine the report to find more details about the NAT gateway charges.

Verify that the security groups attached to the EC2 instances allow outgoing traffic only to the IP addresses that the hostname resolves to, the VPC CIDR block, and the AWS IP address ranges for Amazon S3 and DynamoDB.

Verify that the gateway VPC endpoints for Amazon S3 and DynamoDB are both set up and associated with the route tables of the private subnets.

Question # 46

A network engineer needs to standardize a company's approach to centralizing and managing interface VPC endpoints for private communication with AWS services. The company uses AWS Transit Gateway for inter-VPC connectivity between AWS accounts through a hub-and-spokemodel. The company's network services team must manage all Amazon Route 53 zones and interface endpoints within a shared services AWS account. The company wants to use this centralized model to provide AWS resources with access to AWS Key Management Service (AWS KMS) without sending traffic over the public internet.

What should the network engineer do to meet these requirements?

In the shared services account, create an interface endpoint for AWS KMS. Modify the interface endpoint by disabling the private DNS name. Create a private hosted zone in the shared services account with an alias record that points to the interface endpoint. Associate the private hosted zone with the spoke VPCs in each AWS account.

Question # 48

A company is planning to use an AWS Transit Gateway hub and spoke architecture to migrate to AWS. The current on-premises multi-protocol label switching (MPLS) network has strict controls that enforce network segmentation by using MPLS VPNs. The company has provisioned two 10 Gbps AWS Direct Connect connections to provide resilient, high-speed, low-latency connectivity to AWS.

A security engineer needs to apply the concept of network segmentation to the AWS environment to ensure that virtual routing and forwarding (VRF) is logically separated for each of the company's software development environments. The number of MPLS VPNs will increase in the future. On-premises MPLS VPNs will have overlapping address space. The company's AWS network design must support overlapping address space for the VPNs.

Which solution will meet these requirements with the LEAST operational overhead?

Deploy a software-defined WAN (SD-WAN) head-end virtual appliance and an SD-WAN controller into a Transit Gateway Connect VPC. Configure the company's edge routers to be managed by the new SD-WAN controller and to use SD-WAN to segment the traffic into the defined segments for each of the company's development environments.

Configure IPsec VPNs on the company edge routers for each MPLS VPN for each of the company's development environments. Attach each IPsec VPN tunnel to a discrete MPLS VPN. Configure AWS Site-to-Site VPN connections that terminate at a transit gateway for each MPLS VPN. Configure a transit gateway route table that matches the MPLS VPN for each Transit Gateway VPN attachment.

Create a transit VPC that terminates at the AWS Site-to-Site VRF-aware IPsec VPN. Configure IPsec VPN connections to each VPC for each of the company's development environment VRFs.

Configure a Transit Gateway Connect attachment for each MPLS VPN between the company's edge routers and Transit Gateway. Configure a transit gateway route table that matches the MPLS VPN for each of the company's development environments.
