Exam question from Amazon's AWS Certified Security - Specialty SCS-C02

Question #: 65
Topic #: 1

[All AWS Certified Security - Specialty SCS-C02 Questions]

A company is using Amazon Route 53 Resolver for its hybrid DNS infrastructure. The company has set up Route 53 Resolver forwarding rules for authoritative domains that are hosted on on-premises DNS servers.

A new security mandate requires the company to implement a solution to log and query DNS traffic that goes to the on-premises DNS servers. The logs must show details of the source IP address of the instance from which the query originated. The logs also must show the DNS name that was requested in Route 53 Resolver.

Which solution will meet these requirements?

A. Use VPC Traffic Mirroring. Configure all relevant elastic network interfaces as the traffic source, include amazon-dns in the mirror filter, and set Amazon CloudWatch Logs as the mirror target. Use CloudWatch Insights on the mirror session logs to run queries on the source IP address and DNS name.
B. Configure VPC flow logs on all relevant VPCs. Send the logs to an Amazon S3 bucket. Use Amazon Athena to run SQL queries on the source IP address and DNS name.
C. Configure Route 53 Resolver query logging on all relevant VPCs. Send the logs to Amazon CloudWatch Logs. Use CloudWatch Insights to run queries on the source IP address and DNS name.
D. Modify the Route 53 Resolver rules on the authoritative domains that forward to the on-premises DNS servers. Send the logs to an Amazon S3 bucket. Use Amazon Athena to run SQL queries on the source IP address and DNS name.

Selected Answer: C

C is the only answer as you need to config resolver query logging on all vpc, and cloudwatch log insight indeed allow you to query the source IP address. https://aws.amazon.com/blogs/aws/log-your-vpc-dns-queries-with-route-53-resolver-query-logs/

Correct answer is D. https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver.html. Please read this statement : Resolver rules enable you to create one forwarding rule for each domain name and specify the name of the domain for which you want to forward DNS queries from your VPC to an on-premises DNS resolver and from your on-premises to your VPC. Rules are applied directly to your VPC and can be shared across multiple accounts. so correct answer, based on above statement is D and not C, as it does not specify the requirements to send outbound connections to on-premise.
