Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 716 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 716
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company runs a real-time data ingestion solution on AWS. The solution consists of the most recent version of Amazon Managed Streaming for Apache Kafka (Amazon MSK). The solution is deployed in a VPC in private subnets across three Availability Zones.

A solutions architect needs to redesign the data ingestion solution to be publicly available over the internet. The data in transit must also be encrypted.

Which solution will meet these requirements with the MOST operational efficiency?

  • A. Configure public subnets in the existing VPC. Deploy an MSK cluster in the public subnets. Update the MSK cluster security settings to enable mutual TLS authentication.
  • B. Create a new VPC that has public subnets. Deploy an MSK cluster in the public subnets. Update the MSK cluster security settings to enable mutual TLS authentication.
  • C. Deploy an Application Load Balancer (ALB) that uses private subnets. Configure an ALB security group inbound rule to allow inbound traffic from the VPC CIDR block for HTTPS protocol.
  • D. Deploy a Network Load Balancer (NLB) that uses private subnets. Configure an NLB listener for HTTPS communication over the internet.

Since we are talking about real-time data (UDP packets) ALB is not a viable solution. You don't need to listen HTTPS, so D is eliminated. If you create a new VPC, you must create link between the old one and this is not mentioned in B. So It is A for me.

"You can turn on public access to an MSK cluster at no additional cost... To turn on public access to a cluster, first ensure that the cluster meets all of the following conditions: - The subnets that are associated with the cluster must be public. - Unauthenticated access control must be off and at least one of the following access-control methods must be on: SASL/IAM, SASL/SCRAM, mTLS. - ..." https://docs.aws.amazon.com/msk/latest/developerguide/public-access.html

There is no reference to a NEW VPC being required in the documentation. We can simply configure subnets in the existing VPC.

A, since Kafka is loadbalancing itself. - https://dattell.com/data-architecture-blog/load-balancing-with-kafka/#:~:text=Load%20balancing%20with%20Kafka%20is,partitions%20while%20preserving%20message%20ordering. B - why create new VPC? C / D - Kafka is loadbalacing itself, also NLB can't handle HTTPS.
