What is the primary role of DNS in cloud networking?

To route traffic between different VPCs

To provide a firewall for inbound traffic

To encrypt network traffic between instances

To translate human-readable domain names into IP addresses

A company has multiple VPCs in different regions that need to communicate with each other. The company wants to centralize network management and reduce the number of peering connections. Which solution should the company use?

Set up VPC peering between each pair of VPCs.

Set up a single VPC and use subnets for each region.

Set up a VPN connection between each pair of VPCs.

Set up a transit gateway and attach all VPCs to it.

What does CIDR notation (e.g., 10.0.0.0/24) represent in cloud networking?

A method for defining a range of IP addresses for a network or subnet

A security rule that controls inbound traffic

A routing protocol used between cloud regions

A specific IP address assigned to a virtual machine

A company has two VPCs in the same region. VPC A hosts a web application and VPC B hosts a backend database. The web application must access the database over a private connection. The company wants to minimize cost and administrative overhead while maintaining a private connection. What should the company do?

Expose the database through an internet gateway and have the web application connect over the internet.

Create a VPN connection between VPC A and VPC B.

Create a transit gateway and attach both VPCs to it, then add routes in the transit gateway route table.

Create a VPC peering connection between VPC A and VPC B and add routes in both VPC route tables to the peered VPC CIDR.
