http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.htmlElastic Network Interface (ENI) is a virtual network interface that can be attached to an EC2 instance in a VPC. It enables an EC2 instance to communicate with other resources in a VPC. Each ENI is identified by a unique MAC address and can have multiple private IPv4 addresses, one Elastic IP address, and one public IPv4 address associated with it. ENIs can also be associated with security groups and network access control lists (NACLs) to control traffic.
Answer: A. NACL
The attribute that is not associated with the Elastic Network Interface is the Network Access Control List (NACL). NACLs are stateless and are associated with subnets, not individual ENIs. They are used to control traffic at the subnet level and can allow or deny traffic based on rules that can apply to inbound or outbound traffic.
Answer: B. Security Groups
Security groups are associated with ENIs to control inbound and outbound traffic. They act as a virtual firewall and can allow or deny traffic based on rules that apply to specific protocols, ports, and source/destination IP addresses.
Answer: C. MAC address
Each ENI is identified by a unique MAC address, which is a 48-bit address assigned by the manufacturer of the network interface card. The MAC address is used to identify the ENI on the network.
Answer: D. Source/Destination check flag
The source/destination check flag is associated with ENIs and determines whether Amazon EC2 performs source/destination checks on the ENI. By default, the source/destination check is enabled, which means that EC2 performs checks on traffic that is sent or received by the ENI. However, in some cases, such as when an instance serves as a NAT gateway, the source/destination check must be disabled to allow traffic to flow through the instance.
In conclusion, the attribute that is not associated with the Elastic Network Interface is the Network Access Control List (NACL).
