  1. What is VPC Peering?

    Answer: A networking connection between two VPCs that enables routing traffic between them using private IP addresses

    VPC Peering is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 or IPv6 addresses, as if they were in the same network.

  2. How do Network Access Control Lists (NACLs) differ from Security Groups?

    Answer: NACLs apply at the subnet level and are stateless, while Security Groups apply at the instance level and are stateful

    NACLs act as a firewall at the subnet level and are stateless (must explicitly allow both inbound and outbound), while Security Groups operate at the instance level and are stateful (return traffic is automatically allowed).

  3. What is AWS Site-to-Site VPN primarily used for?

    Answer: Creating an encrypted connection between an on-premises network and an AWS VPC over the public internet

    AWS Site-to-Site VPN creates an encrypted IPsec tunnel between your on-premises network and your Amazon VPC over the public internet, enabling secure hybrid cloud connectivity.

  4. What is the function of Amazon API Gateway?

    Answer: It provides a fully managed service to create, publish, maintain, monitor, and secure APIs

    Amazon API Gateway is a fully managed service that makes it easy to create, publish, maintain, monitor, and secure REST, HTTP, and WebSocket APIs at any scale.

  5. Which type of Elastic Load Balancer operates at the connection level (Layer 4)?

    Answer: Network Load Balancer

    Network Load Balancer operates at the transport layer (Layer 4) and is capable of handling millions of requests per second with ultra-low latency, making it ideal for TCP/UDP traffic.

  6. What is AWS Global Accelerator?

    Answer: A networking service that improves application availability and performance by routing traffic through AWS global network infrastructure

    AWS Global Accelerator is a networking service that uses the AWS global network to optimize the path from users to applications, improving performance and availability by up to 60%.

  7. What is a VPC Endpoint used for?

    Answer: To allow private communication between a VPC and supported AWS services without requiring internet access

    A VPC Endpoint enables private connections between your VPC and supported AWS services without requiring an internet gateway, NAT device, VPN connection, or AWS Direct Connect.
