AWS Certified SysOps Administrator – Associate (legacy) — Question 684

When attached to an Amazon VPC, which two components provide connectivity with external networks? (Choose two.)

Answer options

• A. Elastic IPS (EIP)
• B. NAT Gateway (NAT)
• C. Internet Gateway {IGW)
• D. Virtual Private Gateway (VGW)

Correct answer: B, C

Explanation

An Internet Gateway (IGW) provides a target in your VPC route tables for internet-bound traffic, allowing direct external communication. A NAT Gateway (NAT) allows resources in private subnets to securely connect to the internet or external networks while blocking unsolicited inbound traffic. Elastic IPs (EIP) are static IP addresses rather than connectivity gateways, and Virtual Private Gateways (VGW) are primarily for secure VPN connections to on-premises networks.
