VPC & Networking Flashcards
What is AWS Direct Connect, and in what way does it provide a network connection to the cloud
AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. Direct Connect establishes a private virtual interface from your on-premise network directly to your amazon vpc. it takes one month to set up for completion.
What is AWS Transit Gateway and in what way does it provide a network connection to the cloud
AWS Transit Gateway connects VPCs and on-premises networks through a central hub. It acts as a cloud router –This simplifies your network and puts an end to complex peering relationships(reduces the need for vpc peering when a lot of systems are involved
What is a VPC Endpoint Gateway and how does it allow connectivity to the cloud
A VPC endpoint enables you to privately connect your VPC to supported AWS services and VPC endpoint services powered by AWS PrivateLink without requiring an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Traffic between your VPC and the other service does not leave the Amazon network.
What is Vpc peering service and how does it work with connecting to the cloud
Vpc provides/allows for a private connection when sharing data between 2 or more different vpc’s
What is a VPC Interface endpoint
An interface endpoint is an elastic network interface with a private IP address from the IP address range of your subnet that serves as an entry point for traffic destined to a supported service. Interface endpoints are powered by AWS PrivateLink, a technology that enables you to privately access services by using private IP addresses
What are the only 2 AWS services that support VPC endpoint gateway
Just remember that only S3 and DynamoDB support VPC Endpoint Gateway. All other services that support VPC Endpoints use a VPC Endpoint Interface.
What is the primary use for Internet gateway
Internet Gateway - An Internet Gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between your VPC and the internet. An internet gateway serves two purposes: to provide a target in your VPC route tables for internet-routable traffic, and to perform network address translation (NAT) for instances that have been assigned public IPv4 addresses.
What type of traffic is used for a NAT Gateway
is used for outbound internet access for instances running in a private subnet
What is a virtual private gateway
A VGW is used for IPSec VPN connections to access a VPC.subnet.
What is a VPC route table
The route table is used within a VPC for directing traffic.
What are Edge locations used for
Edge Locations are parts of the Amazon CloudFront content delivery network (CDN) that are all around the world and are used to get content closer to end-users for better
what is Amazon Route 53
Amazon Route 53 features include domain registration, DNS, traffic flow, health checking, and failover.
What speeds is AWS Direct Connect offered at by AWS?
1 GBPS and 10 GBPS
