Amazon AWS Certified Advanced Networking - Specialty Questions and Answers

Question 21

A global company runs business applications in the us-east-1 Region inside a VPC. One of the company's regional offices in London uses a virtual private gateway for an AWS Site-to-Site VPN connection tom the VPC. The company has configured a transit gateway and has set up peering between the VPC and other VPCs that various departments in the company use.

Employees at the London office are experiencing latency issues when they connect to the business applications.

What should a network engineer do to reduce this latency?

Options:

A.

Create a new Site-to-Site VPN connection. Set the transit gateway as the target gateway. Enable acceleration on the new Site-to-Site VPN connection. Update the VPN device in the London office with the new connection details.

B.

Modify the existing Site-to-Site VPN connection by setting the transit gateway as the target gateway. Enable acceleration on the existing Site-to-Site VPN connection.

C.

Create a new transit gateway in the eu-west-2 (London) Region. Peer the new transit gateway with the existing transit gateway. Modify the existing Site-to-Site VPN connection by setting the new transit gateway as the target gateway.

D.

Create a new AWS Global Accelerator standard accelerator that has an endpoint of the Site-to-Site VPN connection. Update the VPN device in the London office with the new connection details.

Question 22

A customer has set up multiple VPCs for Dev, Test, Prod, and Management. You need to set up AWS Direct Connect to enable data flow from on-premises to each VPC. The customer has monitoring software running in the Management VPC that collects metrics from the instances in all the other VPCs. Due to budget requirements, data transfer charges should be kept at minimum.

Which design should be recommended?

Options:

A.

Create a total of four private VIFs, one for each VPC owned by the customer, and route traffic between VPCs using the Direct Connect link.

B.

Create a private VIF to the Management VPC, and peer this VPC to all other VPCs.

C.

Create a private VIF to the Management VPC, and peer this VPC to all other VPCs, enable source/destination NAT in the Management VPC.

D.

Create a total of four private VIFs, and enable VPC peering between all VPCs.

Question 23

A company's existing AWS environment contains public application servers that run on Amazon EC2 instances. The application servers run in a VPC subnet. Each server is associated with an Elastic IP address.

The company has a new requirement for firewall inspection of all traffic from the internet before the traffic reaches any EC2 instances. A security engineer has deployed and configured a Gateway Load Balancer (GLB) in a standalone VPC with a fleet of third-party firewalls.

How should a network engineer update the environment to ensure that the traffic travels across the fleet of firewalls?

Options:

A.

Deploy a transit gateway. Attach a GLB endpoint to the transit gateway. Attach the application VPC to the transit gateway. Update the application subnet route table's default route destination to be the GLB endpoint. Ensure that the EC2 instances' security group allows traffic from the GLB endpoint.

B.

Update the application subnet route table to have a default route to the GLB. On the standalone VPC that contains the firewall fleet, add a route in the route table for the application VPC's CIDR block with the GLB endpoint as the destination. Update the EC2 instances' security group to allow traffic from the GLB.

C.

Provision a GLB endpoint in the application VPC in a new subnet. Create a gateway route table with a route that specifies the application subnet CIDR block as the destination and the GLB endpoint as the target. Associate the gateway route table with the internet gateway in the application VPC. Update the application subnet route table's default route destination to be the GLB endpoint.

D.

Instruct the security engineer to move the GLB into the application VPC. Create a gateway route table. Associate the gateway route table with the application subnet. Add a default route to the gateway route table with the GLB as its destination. Update the route table on the GLB to direct traffic from the internet gateway to the application servers. Ensure that the EC2 instances' security group allows traffic from the GLB.

Question 24

A company has a data center in the us-west-1 Region with a 10 Gbps AWS Direct Connect dedicated connection to a Direct Connect gateway. There are two private VIFs from the same data center location in us-west-1 that are attached to the same Direct Connect gateway.

VIF 1 advertises 172.16.0.0/16 with an AS PATH attribute value of 65000. VIF 2 advertises 172.16.1.0/24 with an AS PATH attribute value of 65000 65000 65000.

How will AWS route traffic to the data center for traffic that has a destination address within the 172.16.1.0/24 network range?

Options:

A.

AWS will route all traffic by using VIF 1.

B.

AWS will route all traffic by using VIF 2.

C.

AWS will use both VIFs for routing by using a round-robin policy.

D.

AWS will use flow control to balance the traffic between the two VIFs.
