Question 1

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 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 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 companys 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?

A : 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 to the development VPC attachment. Configure a route on the staging VPC to direct the traffic for 10.5.0.0 to the staging VPC attachment.

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

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

D : 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 to the development VPC attachment. Configure a route to direct the traffic for 10.5.0.0 to the staging VPC attachment.

Answer: D

Question 2

Company A recently acquired Company B. Company A has a hybrid AWS and on-premises environment that uses a hosted AWS Direct Connect connection, a Direct Connect gateway, and a transit gateway. Company A has a transit VIF to access the resources in its production environment in the us-east-1 Region. Company B has applications that run across multiple VPCs in the us-west-2 Region in a single AWS account. A transit gateway connects all Company B's application VPCs. The CIDR blocks for both companies do not overlap. Company A needs to use the existing Direct Connect connection to access Company Bs applications from the on-premises environment. Which solution will meet these requirements?

A : Create a new Direct Connect gateway in the Company B account. Associate the Company B transit gateway with the new Direct Connect gateway. Create a transit VIF on the existing hosted connection for Company B.

B : Create an association proposal from the Company B account to associate the Company B transit gateway with the Company A Direct Connect gateway. Accept the transit gateway association proposal by logging into the Company A account.

C : Create multiple virtual private gateways. Attach the virtual private gateways to each of Company B's application VPCs. Create a hosted private VIF for each virtual private gateway.

D : Create a new Direct Connect gateway in the Company B account. Associate the Company B transit gateway with the new Direct Connect gateway. Create a hosted private VIF for Company B.

Answer: B

Question 3

A company has established an AWS Direct Connect connection between its customer gateway at its on-premises data center and a virtual private gateway m the AWS Cloud The BGP routing protocol configuration includes the Autonomous System Number {ASN) of 7224 on the AWS end of the connection and the BGP ASN of 65004 on the company end of the connection

The company's IT administrators report that servers that run at the on-premises data center are not able to communicate with the company's web application that runs on a fleet of Amazon EC2 Instances A network engineer performs initial troubleshooting The network engineer finds that the private VIF is operational and that there is a fully established BGP peering session However, the company still cannot route traffic over the private VIF

Which of the following is a possible cause of this connectivity issue?

A : rewall or ACL rules are blocking TCP pod 179 or are blocking high-numbered ephemeral TCP pons

B : provider is advertising 50 prefixes for private VIFs

C : route tables am lacking prefixes that point to the virtual private gateway to which the private VIF is connected

D : er IP addresses for both sides of the BGP peering session are not configured correctly.

Answer: C

Question 4

A company has an on-premises data center in the United States. The data center is connected to AWS by an AWS Direct Connect connection. The data center has a private VIF that is connected to a Direct Connect gateway. Recently, the company opened a new data center in Europe and established a new Direct Connect connection between the Europe data center and AWS. A new private VIF connects to the existing Direct Connect gateway. The company wants to use Direct Connect SiteLink to set up a private network between the data center in the United States and the data center in Europe. Which solution will meet these requirements in the MOST operationally efficient manner?

A : Create a new public VIF from each data center. Enable SiteLink on the new public VIFs.

B : Create a new transit VIF from each data center. Enable SiteLink on the new transit VIFs.

C : Use the existing VIF from each data center. Enable SiteLink on the existing private VIFs.

D : Create a new AWS Site-to-Site VPN connection between the data centers. Configure the new connection to use SiteLink.

Answer: C
