- There is no NAT gateway for the private subnet, so the database server has no routes that give it public internet access to download software updates.
- The database server needs to be assigned a public address from the pool, or assigned an Elastic IP similar to the instance 10.0.0.2.
- The router is not configured properly on the VPC. Add a route to route table for the VPC that routes all traffic for 0.0.0.0/0 to the ID of the internet gateway.
- There is no egress-only internet gateway attached to the private subnet of the VPC.
Correct Answer:
- There is no NAT gateway for the private subnet, so the database server has no routes that give it public internet access to download software updates.
