In order to keep a dedicated connection and more consistent network performance, company ABC has set up 8 active Direct Connections between one of Amazon's Direct Connect locations and the company's colocation environment.
The speed of the connections is 1Gbps for 6 connections and 10 Gbps for the other 2 connections.
The company plans to create several link aggregation groups (LAG) for all the connections.
Which configurations are valid? (Select TWO)
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer - B, C.
According to https://docs.aws.amazon.com/directconnect/latest/UserGuide/lags.html, there are several rules to apply for LAG.
Firstly, all connections in the LAG must use the same bandwidth.
Secondly, in a LAG, a maximum of four connections are allowed.
Option A is incorrect: Because only a maximum of four connections can be configured for a LAG.Option B is correct: Because it meets the conditions mentioned in the above link.
Option C is correct: Same as Option.
B.Option D is incorrect: Because the connections in a LAG cannot use different bandwidth.
In this scenario, Company ABC has set up 8 active Direct Connections with Amazon's Direct Connect location to achieve a dedicated connection and consistent network performance. The speed of the connections is 1Gbps for six connections and 10 Gbps for two connections. The company wants to create several link aggregation groups (LAGs) for all the connections.
A link aggregation group (LAG) is a collection of physical connections that are bundled together to form a single logical connection. This approach helps to increase the aggregate bandwidth and provides redundancy in case of any link failure. AWS allows up to 8 connections per LAG.
Now, let's evaluate each of the given options:
Option A: One LAG with six 1Gbps connections. One LAG with two 10 Gbps connections. This option is valid because the total number of connections is eight, and it splits the 1Gbps connections and 10Gbps connections into two separate LAGs.
Option B: Two LAGs with three 1Gbps connections each. One LAG with two 10 Gbps connections. This option is valid because it splits the 1Gbps connections into two separate LAGs and combines the 10Gbps connections into one LAG.
Option C: One LAG with four 1Gbps connections. One LAG with the other two 1Gbps connections. One LAG with two 10 Gbps connections. This option is also valid because it splits the 1Gbps connections into two separate LAGs and combines the 10Gbps connections into one LAG.
Option D: One LAG with all eight direct connections. This option is invalid because a single LAG can have a maximum of 8 connections, and in this scenario, there are eight connections. If all the connections are bundled together into one LAG, it may lead to oversubscription, and the benefits of link aggregation may not be fully realized.
Therefore, options A, B, and C are valid configurations for creating link aggregation groups (LAGs) for all the connections in the scenario provided.
