Your company is migrating an entire project to AWS. However, as certain legacy databases are too old to be migrated, your team has established two direct connections (10 gigabits) to link the on-premises data center with various AWS services such as S3, EC2, Lambda, etc. Your lead asks you to aggregate the two direct connections ( that use the same AWS device ) to increase the bandwidth. Which combination of steps should you take to fulfill this requirement? (Select TWO)

Answer options:

A.In the AWS Direct Connect console, create a link aggregation group (LAG).
B.Provision two new connections and associate them with the link aggregation group.
C.Associate two existing connections with the LAG in the AWS Direct Connect console.
D.Create an AWS Direct Connect gateway to combine two existing AWS Direct Connect connections over a private virtual interface.

Correct Answer – A, C
As this case needs to aggregate the two direct connections to increase the bandwidth, Direct Connect LAG should be considered. To establish a LAG connection, it needs the below steps:
1, Create a new link aggregation group (LAG).
2, Associate existing connections or new connections with the LAG.Details can be checked in https://docs.aws.amazon.com/directconnect/latest/UserGuide/lags.html.
Option A is correct: AWS Direct Connect supports LAG which uses the Link Aggregation Control Protocol (LACP) to aggregate multiple connections.
Option B is incorrect: LAG supports existing connections. So creating new direct connections is not required.
Option C is correct: Refer to https://docs.aws.amazon.com/directconnect/latest/UserGuide/associate-connection-with-lag.html on how to associate connections with LAG.Option D is incorrect: AWS Direct Connect gateway is used to connect Direct Connect connection to one or more VPCs in the AWS account, which is not needed for this scenario.
