Your company is building a new data center. You currently have an on-premises data center that accesses your single VPC via VPN. You need to provide access to your single VPC to your new data center. Since your new data center build is already over budget, you need to keep costs low.
How should you accomplish this?

  1. Add a Private VIF and create a Direct Connect connection.
  2. Create a new Customer Gateway and add it to your VPN using a CloudHub infrastructure model.
  3. Add a Public VIF and create a Direct Connect connection.
  4. Create a new Virtual Gateway and add it to your VPN using a CloudHub infrastructure model.

Answer(s): B

Explanation:

Create a new Customer Gateway. A Private VIF would work, but you want to keep costs low. A Public VIF is only for AWS specific resources, such as S3. A Virtual Gateway would be created if you were creating a new VPN connection in a new VPC. A Customer Gateway would allow you to add the new datacenter to your VPN.



You have a website hosted on EC2 that is not serving web pages. You have ensured that the server is running and the site is configured properly. What could be the problem?

  1. Your NACL does not allow port 80 outbound.
  2. Your NACL does not allow ports 1024 − 65535 outbound.
  3. Your NACL does not allow ports 1024 − 65535 inbound. D. Your security group does not allow outbound traffic.

Answer(s): B
