LTM can only load balance outbound traffic by using iRules
The correct answer is A. True. LTM virtual servers are designed to process inbound connections, so outbound traffic load balancing has no native virtual server mechanism and requires iRules to intercept and distribute those flows.

Why each option
LTM virtual servers are designed to process inbound connections, so outbound traffic load balancing has no native virtual server mechanism and requires iRules to intercept and distribute those flows.
BIG-IP LTM's standard virtual server model is built around receiving inbound connections destined for a virtual IP address. For outbound traffic - where internal clients initiate connections to external resources - there is no native virtual server construct to distribute load across multiple uplinks or destinations. iRules provide the programmatic control needed to intercept outbound connections and steer them to different pools or paths, making iRules the required and only supported method for outbound load balancing on LTM.
False is incorrect because standard LTM virtual server configuration cannot natively load balance outbound client-initiated traffic; iRules are specifically required to perform this function.
