A company has a transit gateway in AWS Account A. The company uses AWS Resource Access Manager (AWS RAM) to share the transit gateway so that users in other accounts can connect to multiple VPCs in the same AWS Region. AWS Account B contains a VPC (10.0.0.0/16) with subnet 10.0.0.0/24 in the us-west-2a Availability Zone and subnet 10.0.1.0/24 in the us-west-2b Availability Zone. Resources in these subnets can communicate with other VPCs.
A network engineer creates two new subnets: 10.0.2.0/24 in the us-west-2b Availability Zone and 10.0.3.0/24 in the us-west-2c Availability Zone. All the subnets share one route table. The default route 0.0.0.0/0 is pointing to the transit gateway. Resources in subnet 10.0.2.0/24 can communicate with other VPCs, but resources in subnet 10.0.3.0/24 cannot communicate with other VPCs.
What should the network engineer do so that resources in subnet 10.0.3.0/24 can communicate with other VPCs?
A company runs a workload in a single VPC on AWS. The company’s architecture contains several interface VPC endpoints for AWS services, including Amazon CloudWatch Logs and AWS Key Management Service (AWS KMS). The endpoints are configured to use a shared security group. The security group is not used for any other workloads or resources.
After a security review of the environment, the company determined that the shared security group is more permissive than necessary. The company wants to make the rules associated with the security group more restrictive. The changes to the security group rules must not prevent the resources in the VPC from using AWS services through interface VPC endpoints. The changes must prevent unnecessary access.
The security group currently uses the following rules:
• Inbound - Rule 1
Protocol: TCP
Port: 443
Source: 0.0.0.0/0
• Inbound - Rule 2
Protocol: TCP
Port: 443
Source: VPC CIDR
• Outbound - Rule 1
Protocol: All
Port: All
Destination: 0.0.0.0/0
Which rule or rules should the company remove to meet with these requirements?
A company wants to implement a distributed architecture on AWS that uses a Gateway Load Balancer (GWLB) and GWLB endpoints.
The company has chosen a hub-and-spoke model. The model includes a GWLB and virtual appliances that are deployed into a centralized appliance VPC and GWLB endpoints. The model also includes internet gateways that are configured in spoke VPCs.
Which sequence of traffic flow to the internet from the spoke VPC is correct?
