Virtual Private Cloud (VPC) Flashcards
You are designing Internet connectivity for your VPC. The Web servers must be available on the Internet. The application must have a highly available architecture. Which alternatives should you consider? (Choose two.)
A. Configure a NAT instance in your VPC. Create a default route via the NAT instance and associate it with all subnets. Configure a DNS A record that points to the NAT instance public IP address.
B. Configure a CloudFront distribution and configure the origin to point to the private IP addresses of your Web servers. Configure a Route53 CNAME record to your CloudFront distribution.
C. Place all your web servers behind ELB. Configure a Route53 CNMIE to point to the ELB DNS name.
D. Assign EIPs to all web servers. Configure a Route53 record set with all EIPs, with health checks and DNS failover.
E. Configure ELB with an EIP. Place all your Web servers behind ELB. Configure a Route53 A record that points to the EIP.
A. Configure a NAT instance in your VPC. Create a default route via the NAT instance and associate it with all subnets. Configure a DNS A record that points to the NAT instance public IP address.
B. Configure a CloudFront distribution and configure the origin to point to the private IP addresses of your Web servers. Configure a Route53 CNAME record to your CloudFront distribution.
C. Place all your web servers behind ELB. Configure a Route53 CNMIE to point to the ELB DNS name.
D. Assign EIPs to all web servers. Configure a Route53 record set with all EIPs, with health checks and DNS failover.
E. Configure ELB with an EIP. Place all your Web servers behind ELB. Configure a Route53 A record that points to the EIP.
You are implementing AWS Direct Connect. You intend to use AWS public service end points such as Amazon S3, across the AWS Direct Connect link. You want other Internet traffic to use your existing link to an Internet Service Provider. What is the correct way to configure AWS Direct connect for access to services such as Amazon S3?
A. Configure a public Interface on your AWS Direct Connect link. Configure a static route via your AWS Direct Connect link that points to Amazon S3 Advertise a default route to AWS using BGP.
B. Create a private interface on your AWS Direct Connect link. Configure a static route via your AWS Direct connect link that points to Amazon S3 Configure specific routes to your network in your VPC.
C. Create a public interface on your AWS Direct Connect link. Redistribute BGP routes into your existing routing infrastructure; advertise specific routes for your network to AWS.
D. Create a private interface on your AWS Direct connect link. Redistribute BGP routes into your existing routing infrastructure and advertise a default route to AWS.
A. Configure a public Interface on your AWS Direct Connect link. Configure a static route via your AWS Direct Connect link that points to Amazon S3 Advertise a default route to AWS using BGP.
B. Create a private interface on your AWS Direct Connect link. Configure a static route via your AWS Direct connect link that points to Amazon S3 Configure specific routes to your network in your VPC.
C. Create a public interface on your AWS Direct Connect link. Redistribute BGP routes into your existing routing infrastructure; advertise specific routes for your network to AWS.
D. Create a private interface on your AWS Direct connect link. Redistribute BGP routes into your existing routing infrastructure and advertise a default route to AWS.
What is BGP in AWS Direct Connect?
Border Gateway Protocol (BGP) makes the internet work through data routing.
Question #15
You are designing the network infrastructure for an application server in Amazon VPC. Users will access all application instances from the Internet, as well as from an on-premises network. The on-premises network is connected to your VPC over an AWS Direct Connect link. How would you design routing to meet the above requirements?
A. Configure a single routing table with a default route via the Internet gateway. Propagate a default route via BGP on the AWS Direct Connect customer router. Associate the routing table with all VPC subnets.
B. Configure a single routing table with a default route via the Internet gateway. Propagate specific routes for the on-premises networks via BGP on the AWS Direct Connect customer router. Associate the routing table with all VPC subnets.
C. Configure a single routing table with two default routes: on to the Internet via an Internet gateway, the other to the on-premises network via the VPN gateway. Use this routing table across all subnets in the VPC.
D. Configure two routing tables: on that has a default router via the Internet gateway, and other that has a default route via the VPN gateway. Associate both routing tables with each VPC subnet.
