Explanation
Redundant power supplies (B) eliminate single points of hardware failure - if one PSU fails, the switch stays online, directly improving resiliency. VSF (Virtual Switching Framework) (D) is a stacking technology (used by HPE/Aruba) that combines multiple physical switches into one logical switch, so if one member fails, the others continue forwarding traffic seamlessly.
VLAN segmentation (A) is wrong because VLANs partition broadcast domains for organization and security - they don't provide redundancy or failover capability. EIGRP (C) is wrong on two counts: it's a Layer 3 routing protocol (not a switching technology), and the question specifically targets the switching domain.
Memory tip: Resiliency = surviving failures. Think hardware redundancy (PSU backup) + logical redundancy (VSF lets multiple switches act as one). If an option is a routing protocol or just organizes traffic, it doesn't directly make the switch resilient.
