AWS Certified Advanced Networking Specialty Practice Exam 2026 – Complete Study Resource

To support enhanced networking in addition to updating the kernel, it is necessary to flag the Amazon Machine Image (AMI) for enhanced networking. Enhanced networking is a feature that provides higher bandwidth, higher packet per second (PPS) performance, and lower latency for EC2 instances. This functionality is achieved through specific drivers and requires the AMI to be configured correctly to utilize these drivers.

Flagging the AMI informs the AWS infrastructure that the instance launched from that image can leverage enhanced networking capabilities. This is an essential step because without flagging the AMI, the AWS environment will not apply the enhancements, regardless of whether the kernel has been updated to support these features. This ensures that any instance created from the AMI can utilize the enhanced networking features to deliver better network performance.

Other options, while they may pertain to instance configuration or performance, do not directly relate to enabling enhanced networking. For instance, installing additional security features is not necessary for enhanced networking, nor does increasing memory allocation or enabling more virtual CPUs specifically support the enhanced networking capability. These actions may improve performance but are not prerequisites for enabling the feature itself.
