Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 220 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 220
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company has many application VPCs that use AWS Site-to-Site VPN connections for connectivity to an on-premises location. The company’s network team wants to gradually migrate to AWS Transit Gateway to provide VPC-to-VPC connectivity.

The network team sets up a transit gateway that uses equal-cost multi-path (ECMP) routing. The network team attaches two temporary VPCs to the transit gateway for testing. The test VPCs contain Amazon EC2 instances to confirm connectivity over the transit gateway between the on-premises location and the VPCs. The network team creates two new Site-to-Site VPN connections to the transit gateway.

During testing, the network team cannot reach the required bandwidth of 2.5 Gbps over the pair of new Site-o-Site VPN connections.

Which combination of steps should the network team take to improve bandwidth performance and minimize network congestion? (Choose three.)

  • A. Enable acceleration for the existing Site-to-Site VPN connections to the transit gateway.
  • B. Create new accelerated Site-to-Site VPN connections to the transit gateway.
  • C. Advertise the on-premises prefix to AWS with the same BGP AS_PATH attribute across all the Site-to-Site VPN connections.
  • D. Advertise the on-premises prefix to AWS with a different BGP AS_PATH attribute across all the Site-to-Site VPN connections.
  • E. Verify that the transit gateway attachments are present in the Availability Zones of the test VPC.
  • F. Verify that the on-premises location is sending traffic by using multiple lows.

B- Because you need a new Site to Site VPN for enabling acceleration, hence not A C-ECMP requires same attribute to make sure the flow is uniform, hence not D F-Multiple traffic flow from on-premises will help to increase the traffic bandwidth.

It is B and not A because you cannot enable acceleration on existing VPN connections.

Selected Answer: BDF
This combination provides a comprehensive approach to improving bandwidth performance: Improve the performance of individual connections by speeding up VPNs Achieve better load balancing through BGP routing optimization More efficient use of available bandwidth through multi-stream transmission Option A is less effective than B because creating a new accelerated connection is more flexible than modifying an existing one. Option C uses the same AS_PATH attribute, which may not take full advantage of ECMP routing. Although important, option E has less direct impact on improving bandwidth performance. By implementing B, D, and F, network teams can significantly improve bandwidth performance while minimizing network congestion.
