Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 153 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 153
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

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.

  • 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 Transit Gateway 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 diffident paths in Route Analyzer.
  • D. Create a list of paths to check in AWS Transit Gateway 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.

I thought it was D, but it's about reachability in a single VPC. So it's B.

This is one of the biggest problems with AWS, way too many serivces, that could potentially be doing the same (eg monitoring), and we have know them all and their use cases? Would be a lot easier if their developer just had 2 or 3,and we dont have to remember all these nonsense

Selected Answer: A
Option B mentions CloudTrail, which is generally used for auditing AWS API calls rather than tracking changes within a VPC. Option C refers to AWS Transit Gateway Network Manager Route Analyzer, which is designed for analyzing routes in a transit gateway network, not within a single VPC. Option D is similar to Option C and is not applicable for checking connectivity within a single VPC. Therefore, Option A is the most appropriate choice for automatically verifying connectivity after changes in a single VPC.

A change in a VPC is a perfect management api call :) so you are basically explaining why B is right :)

Selected Answer: B
"When a security group change is made, the change event is logged in AWS CloudTrail. CloudTrail then forwards the change event to Amazon EventBridge, which evaluates the change against a series of rules to determine if any actions must be taken. Within EventBridge, a rule will be created to forward all security group change events from CloudTrail to an AWS Lambda function. The Lambda function is responsible for determining if any EC2 instances are impacted by the security group change, and if any Reachability Analyzer paths assessing the connectivity from the internet to the instance exist.
