Aggregating Multiple Connections for AWS Direct Connect

Answer - B.

The AWS documentation mentions the following on link aggregation groups.

A link aggregation group (LAG) is a logical interface that uses the Link Aggregation Control Protocol (LACP) to aggregate multiple 1 gigabit or 10 gigabit connections at a single AWS Direct Connect endpoint, allowing you to treat them as a single, managed connection.

The correct answer is B. Link Aggregation Group (LAG)

Explanation:

AWS Direct Connect is a service that provides a dedicated network connection between on-premises infrastructure and AWS Cloud. Direct Connect provides higher bandwidth and a more consistent network experience compared to Internet-based connections.

AWS Direct Connect allows customers to create multiple connections to the same AWS Direct Connect location using different ports. To aggregate these connections and treat them as a single connection, AWS Direct Connect provides the Link Aggregation Group (LAG) feature.

A LAG combines multiple connections into a single logical connection, providing increased bandwidth capacity and fault tolerance. A LAG can include between two and four connections at speeds of 1 Gbps or 10 Gbps.

The other options are not correct:

A. Direct Connection Peering: Direct Connection Peering is not a feature of AWS Direct Connect.

C. Connection Addition Group: There is no such feature as Connection Addition Group in AWS Direct Connect.

D. VPN Connection Peering: VPN Connection Peering is a feature that allows customers to establish a secure and private connection between two VPCs over the Internet. It is not related to AWS Direct Connect.
