Your company is planning to open an AWS Direct Connect connection.
They need to ensure that their router has the required capabilities to support this connection.
Which of the following needs to be supported by the router? Choose 3 answers from the options given below.
Click on the arrows to vote for the correct answer
A. B. C. D.Answer - A, C and D.
Options B is incorrect since the requirements are clearly mentioned in the documentation.
Please refer to page 2 on the below link under the section "Network Requirements".
https://docs.aws.amazon.com/directconnect/latest/UserGuide/dc-ug.pdfThe AWS Documentation mentions the following on what needs to be supported.
· Your network must use single mode fiber with a 1000BASE-LX (1310nm) transceiver for 1 gigabit Ethernet or a 10GBASE-LR (1310nm) transceiver for 10 gigabit Ethernet.
· Auto-negotiation for the port must be disabled.
Port speed and full-duplex mode must be configured manually.
· 802.1Q VLAN encapsulation must be supported across the entire connection, including intermediate devices.
· Your device must support Border Gateway Protocol (BGP) and BGP MD5 authentication.
· (Optional) You can configure Bidirectional Forwarding Detection (BFD) on your network.
Asynchronous BFD is automatically enabled for AWS Direct Connect virtual interfaces, but will not take effect until you configure it on your router.

https://docs.aws.amazon.com/directconnect/latest/UserGuide/Welcome.htmlAWS Direct Connect is a service provided by Amazon Web Services (AWS) that enables customers to establish a dedicated network connection from their on-premises infrastructure to AWS. This enables a more reliable and consistent network experience compared to an internet-based connection.
To support AWS Direct Connect, the router must have the following capabilities:
BGP (Border Gateway Protocol): Direct Connect uses BGP to exchange routing information between the customer network and AWS. BGP is a standard protocol used for routing traffic between different autonomous systems on the internet.
BGP MD5 authentication: BGP MD5 authentication provides a mechanism to verify the authenticity of BGP messages exchanged between the customer network and AWS. It helps to prevent unauthorized access and protects against potential security threats.
802.1Q VLAN: Virtual LANs (VLANs) enable the segregation of network traffic into different logical networks. AWS Direct Connect requires the use of 802.1Q VLAN tagging to identify the customer's traffic on the connection.
Therefore, the correct answers are A. Single Mode Fibre, C. 802.1Q VLAN, and D. BGP and BGP MD5 authentication.
It's important to note that 1 Gbps copper connections are not supported for AWS Direct Connect as they do not meet the required specifications for the service. AWS Direct Connect requires a minimum of 1 Gbps dedicated network connectivity using single-mode fiber.
