An organization has multiple applications running in VPCs across multiple AWS accounts. The network engineer has deployed a central VPC with a pair of software VPN instances that run IPSec tunnels with dynamic routing to VGWs of all application VPCs.

A bank built a new version of its banking application in AWS using containers that connect to an on-premises database over a VPN connection. This application version requires users to also update their client application. The bank plans to deprecate the earlier client version.

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

Question 351

An organization wants to process sensitive information using the Amazon EMR service. The information is stored in onpremises databases. The output of processing will be encrypted using AWS KMS before it is uploaded to a customerowned Amazon S3 bucket. The current configuration includes a VPS with public and private subnets, with VPN connectivity to the on-premises network. The security organization does not allow Amazon EC2 instances to run in the public subnet.

What is the MOST simple and secure architecture that will achieve the organization's goal?

Use the existing VPC and configure Amazon EMR in a private subnet with an Amazon S3 endpoint.

Use the existing VPS and a NAT gateway, and configure Amazon EMR in a private subnet with an Amazon S3 endpoint.

Create a new VPS without an IGW and configure the VPN and Amazon EMR in a private subnet with an Amazon S3 endpoint.

Question 353

An organization is migrating its on-premises applications to AWS by using a lift-and-shift approach, taking advantage of managed AWS services wherever possible. The company must be able to edit the application code during the migration phase. One application is a traditional three-tier application, consisting of a web presentation tier, an application tier, and a database tier. The external calling client applications need their sessions to remain sticky to both the web and application nodes that they initially connect to.

Which load balancing solution would allow the web and application tiers to scale horizontally independent from one another other?

Use an Application Load Balancer at the web tier and a Classic Load Balancer at the application tier. Set session stickiness on both, but update the application code to create an application-controlled cookie on the Classic Load Balancer.

Use an Application Load Balancer at both the web and application tiers, setting session stickiness at the target group level for both tiers.

Deploy a web node and an application node as separate containers on the same host, using task linking to create a relationship between the pair. Add an Application Load Balancer with session stickiness in front of all web nodecontainers.

Use a Network Load Balancer at the web tier, and an Application Load Balancer at the application tier. Enable session stickiness on the Application Load Balancer, but take advantage of the native WebSockets protocols available to theNetwork Load Balancer.

Question 354

You have a static VPN connecting your data center and your VPC. You currently have 50 routes added to your route table. You want to add more; how should you do this?

50 is the most you can have for any connection.

Just add them, you have a maximum of 100 static routes per route table.

Set up Direct Connect. A VPN will not support more routes.

Convert your VPN to a dynamic VPN and use BGP.

Question 356

A company uses an Application Load Balancer (ALB) to provide access to a multi-tenant web application for 25 customers.

The company creates a unique hostname for each customer to use to access the application. Hostnames use the format customer-name.example.com.

Each customer has a dedicated group of Amazon EC2 instances that run their own version of the web application. When a customer visits customer-name.example.com, the ALB should route the request to the correct group of EC2 instances. The company requires a highly available solution that is easy to maintain. Which solution meets these requirements at the LOWEST cost?

Create one ALB for all customers. Create a listener rule that includes an HTTP header condition to match the URL. Add aforward action to route the request to the customer target group. Use Amazon Route 53 to create an alias recordfor eachcustomer-name.example.com hostname that points to the ALB.

Create one ALB for each customer. Configure the listener to route requests to the customer target group. Configure an NGINX proxy server to manage connections to each ALUse Amazon Route 53 to create a CNAME record for eachcustomer-name.example.com hostname that points to the NGINX proxy server.

Question 357

A company is deploying a new web application that uses a three-tier model with a public-facing Network Load Balancer and web servers in an Amazon VPC. The application servers are hosted in the company's data center. There is an AWS Direct Connect connection between the VPC and the company's data center. Load testing results indicate that up to 100 servers, equally distributed across multiple Availability Zones, are required to handle peak loads. The network engineer needs to design a VPC that has a /24 CIDR assigned to it.

How should the engineer allocate subnets across three Availability Zones for each tier?

Network Load Balancer: /29 per subnet Web: /26 per subnet

Network Load Balancer: /28 per subnet Web: /25 per subnet

Network Load Balancer: /28 per subnet Web: /27 per subnet

Network Load Balancer: /28 per subnet Web: /26 per subnet

Question 359

A financial company is designing a secure AWS network architecture to support a hybrid cloud strategy. Systems deployed in the AWS Cloud are mission critical and have strict availability requirements. The company anticipates the need for hundreds of VPCs. Instances will be transient and rely heavily on DNS resolution. The applications must be designed to have Availability Zone isolation and tolerate the loss of an Availability Zone. What is the MOST reliable way to implement DNS in this scenario?

Create a new DHCP options set with DNS settings with on-premises DNS servers that traverse an AWS Direct Connect connection.

Create private hosted zones and share them with each VP

Use Amazon Route 53 Resolver for hybrid DNS.

Modify the default DHCP options set with a fleet of proxy DNS servers that are deployed in each VPC.

Create a fleet of DNS proxy servers in a central VPC. Share the proxy fleet with each VPC using AWS PrivateLink.
