Network Requirements for Establishing a Direct Connect Connection

Answer - A,B and D.

The AWS Documentation mentions the following.

To use AWS Direct Connect in an AWS Direct Connect location, your network must meet one of the following conditions:

· Your network is collocated with an existing AWS Direct Connect location.

· You are working with an AWS Direct Connect partner who is a member of the AWS Partner Network (APN)

You are working with an independent service provider to connect to AWS Direct Connect.

In addition, your network must meet the following conditions:

· Connections to AWS Direct Connect require single mode fiber, 1000BASE-LX (1310nm) for 1 gigabit Ethernet, or 10GBASE-LR (1310nm) for 10 gigabit Ethernet.

Auto Negotiation for the port must be disabled.

You must support 802.1Q VLANs across these connections.

· Your network must support Border Gateway Protocol (BGP) and BGP MD5 authentication.

AWS Direct Connect is a service provided by Amazon Web Services that allows you to establish a dedicated network connection between your data center, office, or colocation environment and AWS. This connection can be used to access AWS services and resources privately and with high bandwidth, and can be used as an alternative to using the internet to access AWS services.

To establish a Direct Connect connection, there are certain network requirements that must be met. These include:

A. Connections to AWS Direct Connect require single mode fiber, 1000BASE-LX (1310nm) for 1 gigabit Ethernet

This requirement means that the connection between your network and AWS Direct Connect must be made using single mode fiber with a 1000BASE-LX (1310nm) interface for 1 gigabit Ethernet. This is a standard interface that is widely used in the networking industry and ensures that your connection is compatible with AWS Direct Connect.

B. Support Border Gateway Protocol (BGP)

BGP is a routing protocol used to exchange routing information between different networks on the internet. Support for BGP is a requirement for establishing a Direct Connect connection as it enables you to advertise your network prefixes to AWS and receive AWS's network prefixes in return.

C. Support for AES Encryption

AES (Advanced Encryption Standard) is a symmetric encryption algorithm that is widely used for securing data. Support for AES encryption is required to ensure that your Direct Connect connection is secure and your data is protected in transit.

D. Support for BGP MD5 authentication.

BGP MD5 authentication is a security feature that uses a shared secret key to authenticate BGP messages exchanged between two routers. Support for BGP MD5 authentication is a requirement for establishing a Direct Connect connection as it ensures that the BGP messages exchanged between your network and AWS are authenticated and secure.

In summary, the three network requirements for establishing a Direct Connect connection are: support for single mode fiber with a 1000BASE-LX (1310nm) interface for 1 gigabit Ethernet, support for BGP routing protocol, and support for AES encryption and BGP MD5 authentication for security.
