AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 91

A global film production company uses the AWS Cloud to encode and store its video content before distribution. The company's three global offices are connected to the us-east-1 Region through AWS Site-to-Site VPN links that terminate on a transit gateway with BGP routing activated.

The company recently started to produce content at a higher resolution to support 8K streaming. The size of the content files has increased to three times the size of the content files from the previous format. Uploads of files to Amazon EC2 instances are taking 10 times longer than they did with the previous format.

Which actions should a network engineer recommend to reduce the upload times? (Choose two.)

Answer options

• A. Create a second VPN tunnel from each office location to the transit gateway. Activate equal-cost multi-path (ECMP) routing.
• B. Modify the transit gateway to activate Jumbo MTU on the VPN tunnels to each office location.
• C. Replace the existing VPN tunnels with new tunnels that have acceleration activated.
• D. Upgrade each EC2 instance to a modern instance type. Activate Jumbo MTU in the operating system.
• E. Replace the existing VPN tunnels with new tunnels that have IGMP activated.

Correct answer: A, C

Explanation

The correct answers are A and C because creating additional VPN tunnels with ECMP routing can balance the load and improve throughput, while acceleration on new tunnels can significantly reduce latency and increase upload speeds. Options B, D, and E do not directly address the issue of upload speed as effectively as the correct options.
