Your company currently has a Link Aggregation Group to AWS with two 1Gbps connections.
What is the best way to increase throughput on this Link Aggregation Group?

A. B. C. D.Answer - C.
As per the AWS documentation , the Link Aggregation Group has the following rules , hence only option C can be used in this instance.
You can create a LAG from existing connections or provide new connections.
After creating the LAG, you can assign existing connections (independent as well as connections that are part of another LAG).
The following rules apply:
· All connections in the LAG must have the same bandwidth.
The following bandwidths are supported: 1 Gbit / s and 10 Gbit / s.
· A LAG can contain a maximum of 4 connections.
Each link in the LAG must be considered individually for the overall connection limit for the region.
· All connections in the LAG must run at the same AWS DirectConnect endpoint.

http://docs.aws.amazon.com/directconnect/latest/UserGuide/lags.htmlLink Aggregation Group (LAG) allows combining multiple physical connections into a single logical connection to provide higher bandwidth and redundancy. To increase the throughput on the existing LAG with two 1Gbps connections, we need to add more bandwidth.
Option A: Adding one 10Gbps connection to the LAG will increase the total bandwidth to 12Gbps. However, this will cause an imbalance in the traffic flow as the existing two connections are only 1Gbps each. This option may also require upgrading the network equipment to support 10Gbps.
Option B: Adding two 10Gbps connections to the LAG will increase the total bandwidth to 22Gbps, which is a significant improvement. However, this option may also require upgrading the network equipment to support 10Gbps.
Option C: Adding two 1Gbps connections to the LAG will increase the total bandwidth to 4Gbps. This option may not provide enough improvement in throughput, and adding more 1Gbps connections may not be feasible due to the limited number of available ports on the network equipment.
Option D: Adding three 1Gbps connections to the LAG will increase the total bandwidth to 5Gbps. While this option provides more bandwidth than option C, it may not be enough to meet the required throughput. Moreover, adding more 1Gbps connections may not be feasible due to the limited number of available ports on the network equipment.
Therefore, the best option to increase throughput on the LAG is to add two 10Gbps connections (Option B). This option provides a significant improvement in bandwidth and may require upgrading the network equipment to support 10Gbps.
