Question 19 (Topic 1)

An online retail company is running a web application in the us-wast-2 Region and serves consumers in the United States. The company plans to expand across several countries in Europe and wants to provide low latency for all its users. The application needs to identify the users’ IP addresses and provide localized content based on the users’ geographic location. The application uses HTTP GET and POST methods for its functionality. The company also needs to develop a failover mechanism that works for GET and POST methods and is based on health checks. The failover must occur in less than 1 minute for all clients. Which solution will meet these requirements?

  • ○ Configure a Network Load Balancer (NLB) for the application in each environment in the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the NLBs in each Region.
  • ○ Configure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the ALBs in each Region.
  • ○ Configure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create Amazon Route 53 public hosted zones that have failover routing policies.
  • ○ Configure a Network Load Balancer (NLB) for the application in each environment in the new AWS Regions. Create an Amazon CloudFront distribution. Configure an origin group with origin failover options.
Question 20 (Topic 1)

A company has two data centers that are interconnected with multiple redundant links from different suppliers. The company Uses IP addresses that are within the 172.16,0.0/16 CIDR block. The company is running iBGP between the two data centers by using a private Autonomous System Number (ASN) and IGP. The company is moving toward a hybrid setup in which the company will initially use one VPC in the AWS Cloud. An AWS Direct Connect connection runs from the first data center to a Direct Connect gateway by using a private VIF. On the connection, the company advertises a summarized route for the 172.16.0.0/16 network. The company is planning to set up a second summarized route from the second data center to a different Direct Connect location. The company needs to implement a solution to route traffic to and from AWS through the first Direct Connect connection. The solution must use the second Direct Connect connection for failover purposes only. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Prepend the private ASN on the BGP announcements to AWS from the second data center. Add a second VIF in the first Direct Connect connection. Advertise the same network without any prepends from the first data center. Implement the same setup for the BGP announcement from AWS to the two data centers.
  • ○ Tag the BGP announcements with the local preference BGP community tags. Set the tag to high preference for the first data center. Set the tag to low preference for the second data center. Configure the second data center’s router to have a lower local preference for the direct AWS BGP advertisements than for the advertisement from the fist data center.
  • ○ Configure the Direct Connect gateway to prefer routing through the Direct Connect connection with the first data center. Configure the second data center’s router to have a lower local preference for the direct AWS BGP advertisements than for the advertisement from the first data center.
  • ○ Configure the focal AWS Region BGP community tag on the BGP route that is advertised from the fist data center. Configure AS_PATH prepends on the BGP announcements from the second data center.
Question 21 (Topic 1)

A company has a VPC in the AWS Cloud. The company recently acquired a competitor that also has a VPC the AWS Cloud. A network engineer discovers an IP address overlap between the two VPCs. Both VPCs require access to an AWS Marketplace partner service. Which solution will ensure interoperability among the VPC hosted services and the AWS Markelplace partner service?

Select an option, then click Submit answer.

  • ○ Configure VPC peering with static routing between the VPCs. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.
  • ○ Configure a NAT gateway in the VPCs. Configure default routes in each VPC to point to the local NAT gateway. Attach each NAT gateway to a transit gateway. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.
  • ○ Configure AWS PrivateLink to facilitate connectivity between the VPCs and the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.
  • ○ Configure a NAT instance in the VPCs. Configure default routes in each VPC to point to the local NAT instance. Configure an interface endpoint in each VPC to connect to the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.
