ANS-C00 Exam Question 51

A space exploration company owns a series of telescopes that capture a large number of images and data of the night sky. The images and data are processed on an application hosted on AWS Fargate in a target group assigned to an Application Load Balancer (ALB). The application is made available through the address https
/'space example com
Scientists require another custom-built application hosted on several Amazon EC2 instances within an Auto Scaling group. This application will be made available from the address https://space.example.com/meteor.
The company needs a solution that can automatically scale from a small number of requests overnight to a large number of requests for a future meteor shower.
What is the MOST operationally efficient solution that meets these requirements?

A.Create a Network Load Balancer (NLB). Configure the NLB to listen on two ports. Configure a target group for one port to deliver all IP traffic to the Auto Scaling group to process the custom images.
Configure a target group for the second port to deliver all IP traffic to Fargate Use path-based routing in the ALB to route traffic for the URL prefix /meteor to the first target group. Route all other paths to the second target group.

B.Create a new target group. Configure the Auto Scaling group of the EC2 instances to use the target group Update the ALB by adding a listener rule that redirects /meteor to the new target group.

C.Place the ALB behind an Amazon CloudFront distribution. Create a Lambda@Edge function that parses the request URI and adds the path-pattern header with the IP addresses of the EC2 instances to any request for /meteor. Add a listener rule to the ALB that looks for the HTTP header and uses the IP addresses of the EC2 instances to forward the traffic.

D.Update the existing target group with the new EC2 instances. Update the application's ALB by adding a listener rule that redirects /meteor to the newly added EC2 instances.

ANS-C00 Exam Question 52

A company wants to migrate its workloads to the AWS Cloud. The company has two web applications and wants to run them in separate, isolated VPCs. The company needs to use Elastic Load Balancing to distribute requests between application instances.
For security reasons, internet gateways must not be attached to the application VPCs. Inbound HTTP requests to the application must be routed through a centralized VPC. and the application VPCs must not be exposed to any other inbound traffic The application VPCs cannot be allowed to initiate any outbound connections What should a network engineer do to meet these requirements?

A.Run the applications behind private Application Load Balancers (ALBs) in separate VPCs. Create a public Network Load Balancer (NLB) in the centralized VPC. Create target groups for the private IP addresses of the ALBs Configure host-based routing to route application traffic to the corresponding target group through the NLB.

B.Run the applications behind private Network Load Balancers (NLBs) in separate VPCs. Create VPC peering connections between the application VPCs and the centralized VPC. Create a public Application Load Balancer (ALB) in the centralized VPC. Create target groups for the private DNS names of the NLBs. Configure host-based routing to route application traffic between individual applications though the ALB.

C.Run the applications behind private Application Load Balancers (ALBs) in separate VPCs. Create a public Network Load Balancer (NLB) in the centralized VPC. Create target groups for the private DNS names of the ALBs Configure host-based routing to route application traffic to the corresponding target group through the NLB.

D.Run the applications behind private Network Load Balancers (NLBs) in separate VPCs. Configure each NLB as an AWS PrivateLink endpoint service with associated VPC endpoints in the centralized VPC Create target groups that include the private IP addresses of each endpoint. Create a public Application Load Balancer (ALB) in the centralized VPC. Configure host-based routing to route application traffic to the corresponding target group through the ALB.

ANS-C00 Exam Question 53

A company is connecting to a VPC over an AWS Direct Connect using a private VIF, and a dynamic VPN connection as a backup. The company's Reliability Engineering team has been running failover and resiliency tests on the network and the existing VPC by simulating an outage situation on the Direct Connect connection.
During the resiliency tests, traffic failed to switch over to the backup VPN connection.
How can this failure be troubleshot?

A.Ensure that Bidirectional Forwarding Detection is enabled on the Direct Connect connection

B.Reconfigure the Direct Connect session from static routes to Border Gateway Protocol (BGP) peering.

C.Configure a virtual private gateway for the VPN and another virtual private gateway for Direct Connect.

D.Confirm that the same routes are being advertised over both the VPN and Direct Connect.

ANS-C00 Exam Question 54

An AWS CloudFormation template is being used to create a VPC peering connection between two existing operational VPCs, each belonging to a different AWS account. All necessary components in the 'Remote' (receiving) account are already in place.
The template below creates the VPC peering connection in the Originating account. It contains these components:
AWSTemplateFormation Version: 2010-09-09
Parameters:
Originating VCId:
Type: String
RemoteVPCId:
Type: String
RemoteVPCAccountId:
Type: String
Resources:
newVPCPeeringConnection:
Type: 'AWS::EC2::VPCPeeringConnection'
Properties:
VpcdId: !Ref OriginatingVPCId
PeerVpcId: !Ref RemoteVPCId
PeerOwnerId: !Ref RemoteVPCAccountId
Which additional AWS CloudFormation components are necessary in the Originating account to create an operational cross-account VPC peering connection with AWS CloudFormation? (Select two.)

A.Resources:NewEC2SecurityGroup:Type: AWS::EC2::SecurityGroup

B.Resources:NetworkInterfaceToRemoteVPC:Type: "AWS::EC2NetworkInterface"

C.Resources:newEC2Route:Type: AWS::EC2::Route

D.Resources:VPCGatewayToRemoteVPC:Type: "AWS::EC2::VPCGatewayAttachment"

E.Resources:newVPCPeeringConnection:Type: 'AWS::EC2VPCPeeringConnection'PeerRoleArn: !Ref PeerRoleArn

ANS-C00 Exam Question 55

B.Redshift

C.Simple Storage Service (S3)

D.Glacier
