Topic 1 Question 226
A company is running its application servers on Amazon EC2 instances. The EC2 instances run in separate VPCs that are connected by a transit gateway. The EC2 instances launch in a private subnet with a route to the transit gateway for internal and external connectivity. The external connectivity is provided by a VPC with firewall devices that perform an inspection for packets that ingress and egress through an internet gateway.
A network engineer needs to help the company’s application team increase the payload size per packet delivery between the EC2 instances. All network connectivity must be through the transit gateway
What should the network engineer do to meet these requirements?
Enable jumbo frames on the transit gateway. Instruct the application team to set the maximum transmission unit (MTU) of the system’s network interfaces to 9001 bytes.
Instruct the application team to set the maximum transmission unit (MTU) of the VPC to 8500 bytes.
Instruct the application team to set up enhanced networking on the system by using the enhanced networking adapter. Set the maximum transmission unit (MTU) to 9001 bytes.
Instruct the application team to set the maximum transmission unit (MTU) of the system’s network interfaces to 8500 bytes.

Question: "All network connectivity must be through the transit gateway"
Docs: Packets with a size larger than 8500 bytes that arrive at the transit gateway are dropped. https://docs.aws.amazon.com/vpc/latest/tgw/transit-gateway-quotas.html

The correct answer is D because:
8500 bytes is the maximum MTU supported by Transit Gateway Setting the system interfaces to 8500 ensures compatibility Prevents packet fragmentation Maximizes payload size while maintaining network stability Works with the existing architecture including firewalls

Enabling Jumbo frames and setting up MTU of the network interfaces to 9001 will help to improve the connectivity.
