A global film company uploads large 8K video files to EC2 via Site-to-Site VPNs that terminate on a Transit Gateway with BGP. File sizes tripled but uploads now take ten times longer than before. Which recommendations should a network engineer make to reduce upload times? (Choose two.)

Creating a second VPN tunnel and enabling ECMP routing allows traffic to be distributed across multiple tunnels, effectively increasing the available bandwidth and reducing congestion for large file transfers. Replacing existing VPN tunnels with new ones that have acceleration enabled utilizes AWS Global Accelerator or similar services, which optimize the network path from the on-premises locations to AWS, significantly reducing latency and improving throughput for data transfer. Upgrading EC2 instances or enabling Jumbo MTU on the guest OS would not address the network bottleneck between the on-premises network and AWS. IGMP is for multicast management, not for improving VPN throughput.
