200-155 · Question #36
A UCS administrator has been tasked with creating a new server profile. Which two pools can be used to assign Layer 2 interface information? (Choose two)
The correct answer is B. Mac Address E. WWN. To assign Layer 2 interface information within a Cisco UCS server profile, administrators utilize MAC address pools for Ethernet and WWN pools for Fibre Channel connectivity.

Why each option
To assign Layer 2 interface information within a Cisco UCS server profile, administrators utilize MAC address pools for Ethernet and WWN pools for Fibre Channel connectivity.
Server pools are used to define a collection of physical servers that a server profile can be bound to, not to assign Layer 2 interface information.
MAC address pools are specifically designed to provide unique Layer 2 Ethernet addresses to virtual network interfaces (vNICs) configured within a UCS server profile. These addresses ensure proper identification and communication on Ethernet networks.
IP address pools are used for assigning Layer 3 network addresses to interfaces, not Layer 2 interface information like MAC or WWN addresses.
UUD (or UUID) pools are typically used for assigning unique identifiers to servers for identification purposes, not for Layer 2 network or SAN interface addressing.
WWN (World Wide Name) pools are used to assign unique Layer 2 Fibre Channel addresses (WWPNs for ports and WWNNs for nodes) to virtual Host Bus Adapters (vHBAs) in a UCS server profile. These identifiers are crucial for connectivity and zoning within a Storage Area Network (SAN).
