A user has created an ELB with three instances.
How many security groups will ELB create by default?
3
5
2
1
Explanations:
ELB does not create 3 security groups by default. It can be associated with multiple security groups, but it doesn’t create 3 automatically.
ELB does not create 5 security groups by default. It can have multiple associated groups, but this is not the default behavior.
ELB does not create 2 security groups by default. The default is not two groups.
By default, ELB creates 1 security group to associate with itself, which controls traffic to the load balancer.
I surmise that the answer is:
