  • Topic 1 Question 234

    A company has configured an AWS Cloud WAN core network with edge locations in the us-east-1 Region and the us-west-1 Region. Each edge location has two segments: development and staging. The segments use the default core network policy.

    The company has attached VPCs to the core network. A development VPC is attached to the development segment in us-east-1 and is configured to use the 10.0.0.0/16 CIDR block. A staging VPC is attached to the staging segment in us-west-1 and is configured to use the 10.5.0.0/16 CIDR block. The company has updated the route tables for both VPCs with a route that directs any traffic for 0.0.0.0/0 to the core network.

    The company’s network team needs to establish communication between the two VPCs by using the AWS Cloud WAN core network. The network team is not receiving a response during tests of communication between the VPCs. The network team has verified that security groups and network ACLs are not blocking the traffic.

    What should the network team do to establish this communication?

    • Update both VPC route tables to have a new static route. Configure a route on the development VPC to direct the traffic for 10.0.0.0/16 to the development VPC attachment. Configure a route on the staging VPC to direct the traffic for 10.5.0.0/16 to the staging VPC attachment.

    • Update the segment filter to allow traffic on the development and staging segments.

    • Set the isolate-attachments parameter to False for the development and staging segments.

    • Update the core network policy to add a static route for each segment. Configure a route to direct the traffic for 10.0.0.0/16 to the development VPC attachment. Configure a route to direct the traffic for 10.5.0.0/16 to the staging VPC attachment.
