You have deployed a website that utilizes CloudFront, Elastic Loadbalancer, and S3 to serve content. When users access your site, they receive a "mixed content" security warning. What is most likely the problem?
An organization has multiple applications running in VPCs across multiple AWS accounts. The network engineer has deployed a central VPC with a pair of software VPN instances that run IPSec tunnels with dynamic routing to VGWs of all application VPCs. This central VPC is connected to on-premises resources via a Direct Connect connection using a private VIF. What additional configuration is required to enable the applications in VPCs to communicate with each other and access onpremises resources?
A company is building a hybrid PCI-DSS compliant application that runs in the us-west-2 Region and on-premises. The application sends access logs from all locations to a single Amazon S3 bucket in uswest-2. To protect this sensitive data, the bucket policy is configured to deny access from public IP addresses. How should an engineer configure the network to meet these requirements?
You have two VPCs that you've peered. You created a route for VPC A to get to an instance in VPC. You are unable to ping the instance. You have double checked your security groups and NACLs. Why might this be?
You are deploying an EC2 instance in a private subnet that requires access to the Internet. One of the requirements for this solution is to restrict access to only particular URLs on a whitelist. In addition to the whitelisted URLs, the instances should be able to access any Amazon S3 bucket in the same region via any URL. Which of the following solutions should you deploy? (Choose two.)

You currently use a single security group assigned to all nodes in a clustered NoSQL database. Only your cluster members in one region must be able to connect to each other. This security group uses a self-referencing rule using the cluster security group's group-id to make it easier to add or remove nodes from the cluster.

You need to make this database comply with out-of-region disaster recovery requirements and ensure that the network traffic between the nodes is encrypted when travelling between regions. How should you enable secure cluster communication while deploying additional cluster members in another AWS region?

A.
Create an IPsec VPN between AWS regions, use private IP addresses to route traffic, and create cluster security group rules that reference each other's security group-id in each region.
Answers
A.
Create an IPsec VPN between AWS regions, use private IP addresses to route traffic, and create cluster security group rules that reference each other's security group-id in each region.
