A customer is using ABC Telecom as a network provider. The customer has 10 different offices connected to ABC Telecom's MPLS backbone. The customer is setting up an AWS Direct Connect connection to AWS and has provided the LOA-CFA to ABC Telecom. ABC Telecom has terminated the Direct Connect circuit into their MPLS backbone. To uniquely identify the customer's traffic over the MPLS backbone, the customer must encapsulate all traffic with VLAN tag 100. The customer wants to send traffic to multiple VPCs.
Which two steps should be taken to meet the customer's requirement? (Select two.)

• A.ABC Telecom creates a support ticket with AWS to exchange MPLS labels and include the AWS port as part of their MPLS network.
• B.Send the traffic for all VPCs with the same VLAN tag 100 and use BGP to ensure that proper routing takes place to the appropriate VPC.
• C.The customer performs Q-in-Q tunneling, with the AWS-required VLAN tag in the inside and VLAN
  100 as the outside tag.
• D.Create a support ticket with AWS to request the removal of the outer VLAN tag 100 as the traffic reaches AWS routers.
• E.ABC Telecom removes the other tag before sending the packet to AWS.

A corporate network routing table contains 624 individual RFC 1918 and public IP prefixes. You have two AWS Direct Connect connectors. You congure a private virtual interface on both connections to a virtual private gateway. The virtual private gateway is not currently attached to a VPC. Neither BGP session will maintain the Established state on the customer router. The AWS Management Console reports the private virtual interfaces as Down.
What could you do to address the problem so that the AWS Management Console reports the private virtual interface as Available?

• A.Change the BGP advertisements from the corporate network to only be a default route.
• B.Attach the virtual private gateway to a VPC and enable route propagation.
• C.Filter the public IP prexes on the corporate network from the private virtual interface.
• D.Attach the second virtual interface to an alternative virtual private gateway.

You are designing an AWS Direct Connect solution into your VPC. You need to consider requirements for the customer router to terminate the Direct Connect link at the Direct Connect location.
Which three factors that must be supported should you consider when choosing the customer router? (Select three.)

• A.802.1q trunking
• B.802.1ax or 802.3ad link aggregation
• C.OSPF
• D.BGP
• E.single-mode optical fiber connectivity
• F.1-Gbps copper connectivity

A Network Engineer is troubleshooting a network connectivity issue for an instance within a public subnet that cannot connect to the internet. The first step the Engineer takes is to SSH to the instance via a local bastion within the VPC and runs an ifconfig command to inspect the IP addresses configured on the instance. The output is as follows:

The Engineer notices that the command output does not contain a public IP address. In the AWS Management Console, the public subnet has a route to the internet gateway. The instance also has a public IP address associated with it.
What should the Engineer do next to troubleshoot this situation?

• A.Associate an Elastic IP address to the interface.
• B.Configure the public IP on the interface.
• C.Disable source/destination checking for the instance.
• D.Evaluate the security groups and the network access control list.
