Which AWS service or feature is associated with a subnet in a VPC and is used to control inbound and outbound traffic?
- A . Amazon Inspector
- B . Network ACLs
- C . AWS Shield
- D . VPC Flow Logs
B
Explanation:
Network ACLs (network access control lists) are an optional layer of security for your VPC that act as a firewall for controlling traffic in and out of one or more subnets. You can use network ACLs to allow or deny traffic based on protocol, port, or source and destination IP address. Network ACLs are stateless, meaning that they do not track the traffic that flows through them. Therefore, you must create rules for both inbound and outbound traffic.

A user is moving a workload from a local data center to an architecture that is distributed between
the local data center and the AWS Cloud.
Which type of migration is this?
- A . On-premises to cloud native
- B . Hybrid to cloud native
- C . On-premises to hybrid
- D . Cloud native to hybrid
C
Explanation:
C is correct because moving a workload from a local data center to an architecture that is distributed between the local data center and the AWS Cloud is an example of an on-premises to hybrid migration. A hybrid cloud is a cloud computing environment that uses a mix of on-premises, private cloud, and public cloud services with orchestration between the platforms. A is incorrect because on-premises to cloud native migration is the process of moving a workload from a local data center to an architecture that is fully hosted and managed on the AWS Cloud. B is incorrect because hybrid to cloud native migration is the process of moving a workload from an architecture that is distributed between the local data center and the AWS Cloud to an architecture that is fully hosted and managed on the AWS Cloud. D is incorrect because cloud native to hybrid migration is the process of moving a workload from an architecture that is fully hosted and managed on the AWS Cloud to an architecture that is distributed between the local data center and the AWS Cloud.
