- D. By default, subnets associated with different route tables within the same VPC are isolated from each other
Answer: D
Explanation:
Analysis: VPC route table: A route table is a series of routing and forwarding rules that determine where network traffic is forwarded. A VPC can have one or more VPC route tables in a VPC . The main route table is the route table that comes with the VPC, and the subnet in the VPC is associated with the main route table by default. A custom route table is a route table that can be created by a user in addition to the main route table. You can create as many custom route tables as you need. Each subnet needs to be associated with a VPC routing table that guides the routing and forwarding of EC2 instances within that subnet . Except for one route entry with target of local in the VPC route table, which is used for subnet communication in the VPC, the other route entries are different VPC route tables are isolated from each other.
