A customer is ordering new Power 780 and 795 hardware. Within their data center, existing
HMCs already manage POWER5 and POWER6 deployments. These existing HMCs are
either 7310-CR2, 7042-CR4 or 7042-CR5 models. What must be considered with regard to
the management of POWER7 hardware?

A.
Only their 7042-CR5 HMCs can run the minimum required Version 7 Revision 720 HMC
code.

B.
All their existing HMCs will need to be upgraded to at least Version 7 Revision 720 HMC
code.

C.
Only their 7042-CR4 and 7042-CR5 can run the minimum required Version 7 Revision
720 HMC code.

D.
7042-CR6 is the only supported rack-mounted HMC which can run Version 7 Revision
720 and later HMC code.
