Zorluk: ZorAWS Network Services

A financial analytics firm is deploying 1515 virtual private clouds (VPCs) across multiple AWS accounts to isolate different customer datasets. The firm requires a simplified, central routing hub to enable communication between all VPCs. Furthermore, the security team needs to enforce traffic filtering at the boundary of each subnet to explicitly reject incoming requests from a list of known malicious IP ranges.

Which two AWS network services or configuration components should the firm implement to meet these requirements? (Select TWO.)

  1. AWS Transit Gateway to act as a centralized router for interconnecting the VPCsCevap
  2. Network Access Control Lists (Network ACLs) configured with deny rules for the malicious IP rangesCevap
  3. C
    VPC Peering connections configured in a full mesh network to connect all VPCs
  4. D
    Security Groups configured with deny rules to block the malicious IP ranges at the subnet boundary
  5. E
    AWS Site-to-Site VPN connections between all VPCs to route internal traffic

Cevap

AWS Transit Gateway to act as a centralized router, and Network Access Control Lists (Network ACLs) configured with deny rules
AWS Transit Gateway simplifies the network topology by acting as a central hub that routes traffic between all 1515 VPCs, avoiding the need for a complex full mesh of point-to-point connections. Network ACLs operate at the subnet boundary and support explicit deny rules, which allows the security team to block traffic from the specified malicious IP ranges before it reaches any resources in the subnet.

Adım Adım Çözüm

1
Evaluate the multi-VPC routing requirement.
AWS Transit Gateway is identified as the optimal hub-and-spoke solution for scaling connections across 1515 VPCs.
Creating individual VPC Peering connections or VPN tunnels for 1515 VPCs introduces high management overhead and configuration complexity.
2
Evaluate the subnet-level traffic filtering requirement.
Network ACLs are chosen because they support explicit deny rules and apply at the subnet boundary.
Security Groups cannot satisfy this requirement because they only support allow rules and operate at the instance level.

Anahtar Kavram

Centralized multi-VPC routing using AWS Transit Gateway and subnet-level traffic filtering using stateless Network ACLs.
