Does VPC peering work across regions?
Amazon EC2 now allows peering relationships to be established between Virtual Private Clouds (VPCs) across different AWS regions. Inter-Region VPC Peering provides a simple and cost-effective way to share resources between regions or replicate data for geographic redundancy.
Can VPC be multi region?
With Amazon VPC, you can provision logically isolated virtual networks to host your AWS resources. You can create multiple VPCs within the same region or in different regions, in the same account or in different accounts.
How do I connect two VPCs in different regions?
VPC (Requester): Choose the requester VPC which will request the other VPC for a peering connection. Account: Select My Account. Region: Here, as you want an inter-region connection, choose Another region. VPC (Accepter): Here provide the VPC id of the VPC which is at the other end or getting in requests.
How many VPC regions are there?

| Name | Default | Adjustable |
|---|---|---|
| VPCs per Region | 5 | Yes |
| Subnets per VPC | 200 | Yes |
| IPv4 CIDR blocks per VPC | 5 | Yes (up to 50) |

What are all the different connectivity options available for your VPC?
Network-to-Amazon VPC connectivity options
| Option | Use Case |
|---|---|
| AWS Direct Connect + AWS Transit Gateway + VPN | IPSec VPN connection over private lines to regional router for multiple VPCs |
| AWS VPN CloudHub | Connect remote branch offices in a hub-and-spoke model for primary or backup connectivity |
How many regions are in a VPC?
Currently, Amazon VPC supports five (5) IP address ranges, one (1) primary and four (4) secondary for IPv4. Each of these ranges can be between /28 (in CIDR notation) and /16 in size. The IP address ranges of your VPC should not overlap with the IP address ranges of your existing network.
What is a VPC peering connection?
A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IP addresses. VPC peering allows you to deploy cloud resources in a virtual network that you have defined.
How many VPC peering are there?
You cannot have more than one VPC peering connection between the same two VPCs at the same time. Unicast reverse path forwarding in VPC peering connections is not supported. For more information, see Routing for response traffic.
How many security groups are there in VPC?
A security group acts as a virtual firewall for your instance to control inbound and outbound traffic. When you launch an instance in a VPC, you can assign up to five security groups to the instance. Security groups act at the instance level, not the subnet level.
How many VPC are in a region?
VPC and subnets
| Name | Default | Adjustable |
|---|---|---|
| VPCs per Region | 5 | Yes |
| Subnets per VPC | 200 | Yes |
| IPv4 CIDR blocks per VPC | 5 | Yes (up to 50) |
| IPv6 CIDR blocks per VPC | 1 | No |
Can you establish a peering connection to a VPC in a different region Mcq?
You can establish peering relationships between VPCs across different AWS Regions (also called Inter-Region VPC Peering).
How to create an inter-region VPC Peering connection?
For an inter-region VPC peering connection where the VPCs are in different regions, the request must be made from the region of the requester VPC. To activate the request, the owner of the accepter VPC must accept the request. For an inter-region VPC peering connection, the request must be accepted in the region of the accepter VPC.
What does it mean to have VPC Peering?
A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses Instances in either VPC can communicate with each other as if they are within the same network.
Can a VPC be connected to another VPC?
Instances in either VPC can communicate with each other as if they are within the same network. You can create a VPC peering connection between your own VPCs, or with a VPC in another AWS account. The VPCs can be in different regions (also known as an inter-region VPC peering connection).
Can a VPC be in different regions of AWS?
The VPCs can be in different regions (also known as an inter-region VPC peering connection). AWS uses the existing infrastructure of a VPC to create a VPC peering connection; it is neither a gateway nor a VPN connection, and does not rely on a separate piece of physical hardware.
