Question 1

At launch, how many public IPv4 addresses can be automatically assigned to a single Amazon EC2 instance (excluding Elastic IPs)?

Correct Answer: 1

An EC2 instance can receive at most one automatically assigned public IPv4 address at launch, and it is attached to the primary private IPv4 address on the primary network interface. Additional public IPv4 addresses require associating Elastic IPs to additional private IPv4 addresses on attached network interfaces; those are not auto-assigned and are constrained by instance-type ENI and IP limits. IPv6 addressing is separate and does not affect this limit.
