After an Amazon VPC instance is launched, can I change the VPC security groups it belongs
to?
A.
No. You cannot.
B.
Yes. You can.
C.
Only if you are the root user
D.
Only if the tag “VPC_Change_Group” is true
Explanation:
Security groups are associated with network interfaces. After you launch an instance, you can
change the security groups associated with the instance, which changes the security groups
associated with the primary network interface (eth0).
After an Amazon VPC instance is launched, i think they want to state “After an Amazon EC2 instance is launched”.
The question makes no sence in this way,you dont launch a VPC, you just create one.
Next to that, you can Add/Modify/Delete Security groups in the VPC. is a basic feature of AWS VPC.
Yes, question make sense, cause before VPC EC2 Instances, there were EC2 Classic instances and they were quite different.
