Which of these statements is true with respect to an internal ELB in this scenario?
ELB can support only one subnet in each availability zone.
ELB does not allow subnet selection; instead it will automatically select all the available subnets of the VPC.
If the user is creating an internal ELB, he should use only private subnets.
ELB can support all the subnets irrespective of their zones.
Explanations:
An ELB can span multiple subnets within the same availability zone; it is not limited to one subnet per AZ.
While ELBs can be associated with multiple subnets, users have the option to select which subnets to include; it does not automatically select all available subnets.
Internal ELBs must be placed in private subnets to ensure they are not exposed to the public internet, making this statement true.
ELBs are limited to subnets within the same VPC and can span multiple subnets, but they cannot include subnets from different availability zones that are not specified during creation.
As I recall, the answer is:
If the user is creating an internal ELB, he should use only private subnets.
