Amazon AWS Certified Advanced Networking - Specialty Questions and Answers

Question 13

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-spoke model. 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?

Options:

A.

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.

B.

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 each spoke AWS account with an alias record that points to the interface endpoint. Associate each private hosted zone with the shared services AWS account.

C.

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

D.

In each spoke AWS account, create an interface endpoint for AWS KMS. Modify each 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 each interface endpoint. Associate the private hosted zone with the spoke VPCs in each AWS account.

Question 14

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?

Options:

A.

Create a list of paths between different resources to check in VPC Reachability Analyzer. Create an Amazon EventBridge rule to monitor when a change is made and logged in Amazon CloudWatch. Configure the rule to invoke an AWS Lambda function to test the different paths in Reachability Analyzer.

B.

Create a list of paths between different resources to check in VPC Reachability Analyzer. Create an Amazon EventBridge rule to monitor when a change is made and logged in AWS CloudTrail. Configure the rule to invoke an AWS Lambda function to test the different paths in Reachability Analyzer.

C.

Create a list of paths to check in AWS Network Manager Route Analyzer. Create an Amazon EventBridge rule to monitor when a change is made and logged in Amazon CloudWatch. Configure the rule to invoke an AWS Lambda function to test the different paths in Route Analyzer.

D.

Create a list of paths to check in AWS Network Manager Route Analyzer. Create an Amazon EventBridge rule to monitor when a change is made and logged in AWS CloudTrail. Configure the rule to invoke an AWS Lambda function to test the different paths in Route Analyzer.

Question 15

A company wants to improve visibility into its AWS environment. The AWS environment consists of multiple VPCs that are connected to a transit gateway. The transit gateway connects to an on-premises data center through an AWS Direct Connect gateway and a pair of redundant Direct Connect connections that use transit VIFs. The company must receive notification each time a new route is advertised to AWS from on premises over Direct Connect.

What should a network engineer do to meet these requirements?

Options:

A.

Enable Amazon CloudWatch metrics on Direct Connect to track the received routes. Configure a CloudWatch alarm to send notifications when routes change.

B.

Onboard Transit Gateway Network Manager to Amazon CloudWatch Logs Insights. Use Amazon EventBridge (Amazon CloudWatch Events) to send notifications when routes change.

C.

Configure an AWS Lambda function to periodically check the routes on the Direct Connect gateway and to send notifications when routes change.

D.

Enable Amazon CloudWatch Logs on the transit VIFs to track the received routes. Create a metric filter Set an alarm on the filter to send notifications when routes change.

Question 16

A company is hosting an application on Amazon EC2 instances behind a Network Load Balancer (NLB). A solutions architect added EC2 instances in a second Availability Zone to improve the availability of the application. The solutions architect added the instances to the NLB target group.

The company's operations team notices that traffic is being routed only to the instances in the first Availability Zone.

What is the MOST operationally efficient solution to resolve this issue?

Options:

A.

Enable the new Availability Zone on the NLB

B.

Create a new NLB for the instances in the second Availability Zone

C.

Enable proxy protocol on the NLB

D.

Create a new target group with the instances in both Availability Zones
