Explanation
NGINX (A) and HAProxy (C) are the two open-source load balancers commonly used in ECS (Elastic Container Service / Enterprise Content Store) implementations because both are freely available, widely adopted in containerized environments, and natively support dynamic service discovery and health-checking features essential for container orchestration.
The distractors are all commercial/proprietary products: Brocade (B) is a networking hardware/software vendor with proprietary load balancing solutions; F5 (D) refers to F5 Networks' BIG-IP, a commercial appliance/software; and Kemp (E) is a commercial load balancer vendor - none of these are open-source.
Memory tip: Think "NH = No Hardware required" - NGINX and HAProxy are the open-source software-only options, while the others (Brocade, F5, Kemp) are vendor brands associated with paid, proprietary products.
