You create a service profile within ORG C with two vNICs. Each vNIC is assigned to the MAC pool named “vmware”. Which two possible MAC addresses could be assigned to the vNICs? (Choose two.)
A. 00:25:B5:FF:00:01
B. 00:25:B5:EE:00:01
C. 00:25:B5:DD:00:01
D. 00:25:B5:BB:00:01
E. 00:25:B5:AA:00:01
Correct Answer: AD

Explanation:
Cisco UCS Management domains can coexist along with many other UCSM domains and with servers other than Cisco UCS servers, all of which can have their own sets of unique hardware identifiers and pools. The presentation of duplicate WWNs and MAC addresses to the LAN or SAN could naturally be a major source of complications.
To avoid these issues, adopt an enumeration scheme for domains, such that domain ID’s are embedded in the high-order byte range of all pools, including MAC, WWNN, WWPN and UUID. Best practices are to embed either a simple domain ID, or a site/domain pair, along with a fabric side indicator to guarantee uniqueness and identify fabric source. For example, a MAC pool block would take the form 00:25:B5:23:BX:YY, where 00:25:B5 designates Cisco UCS, 23 indicates site 2, domain 3, and B indicates the B-side fabric. Smaller environments could shorten the encoding to just domain and fabric side, as in 00:25:B5:1A:XX:YY.
