Amazon Exam ANS-C01 Topic 4 Question 24 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 24
Topic #: 4

A company's network engineer is designing an active-passive connection to AWS from two on-premises data centers. The company has set up AWS Direct Connect connections between the on-premises data centers and AWS. From each location, the company is using a transit VIF that connects to a Direct Connect gateway that is associated with a transit gateway.

The network engineer must ensure that traffic from AWS to the data centers is routed first to the primary data center. The traffic should be routed to the failover data center only in the case of an outage.

Which solution will meet these requirements?

ASet the BGP community tag for all prefixes from the primary data center to 7224:7100. Set the BGP community tag for all prefixes from the failover data center to 7224:7300

BSet the BGP community tag for all prefixes from the primary data center to 7224:7300. Set the BGP community tag for all prefixes from the failover data center to 7224:7100

CSet the BGP community tag for all prefixes from the primary data center to 7224:9300. Set the BGP community tag for all prefixes from the failover data center to 7224:9100

DSet the BGP community tag for all prefixes from the primary data center to 7224:9100. Set the BGP community tag for all prefixes from the failover data center to 7224:9300

Suggested Answer: C

The correct solution is to use an S3 interface endpoint and an on-premises DNS resolver. An S3 interface endpoint allows you to access Amazon S3 using private IP addresses within your VPC. An on-premises DNS resolver can be configured to forward the DNS queries for the S3 domain names to the S3 interface endpoint, so that the on-premises workloads can access Amazon S3 privately over the VPN connection. This solution is operationally efficient, as it does not require any additional infrastructure or changes to the existing workloads. The VPC workloads can continue to use the S3 gateway endpoint, which provides lower latency and higher throughput than the S3 interface endpoint.
