  D. Providing QuickSync 2 feature

  Correct Answer: C

• Question 23:

  A company receives their first MX7000 chassis. They connect all the provided power supply cables into two different PDUs on different power grids for redundancy. Each of the six power supplies is cabled and has green LEDs. One Management Module is present along with all system fans. Grid redundancy is configured as the power redundancy mode. The chassis is fully populated with six compute sleds and one IOM but only two of the six sleds will power on.

  What is the possible reason for this issue?

  A. An additional IOM is required to power on and manage the remaining sleds.

  B. Two Management Modules are required to power on the populated chassis.

  C. Power supply unit redundancy policy was not used.

  D. Mixed high line and low line AC inputs in the same chassis is not supported.

  Correct Answer: C

• Question 28:

  In the assigned mapping of the MX5016s storage sled what is an assignment option used for independent storage to be mapped to a compute sled?

  A. Drive-assigned enables the MX5016s to be split among multiple compute sleds. Each compute node only "sees" the disks that are assigned to it and not the others.

  B. Drive-assigned enables the MXG610s to the first eight drives in the MX5016s.

  C. Enclosure-assigned enables the MX5016 to be split among multiple compute sleds. Each compute node only "sees" the disks that are assigned to it and not the others.

  D. Enclosure-assigned enables the MXG610s to the first eight drives in the MX5016s.

  Correct Answer: A

• Question 29:

  What is the benefit of C22 power inlet connectors on the MX7000 chassis?

  A. Meet higher power requirements

  B. C22 connectors are now standard on PowerEdge

  C. Allow for higher exhaust temperatures

  D. Enable linking together power supplies

  Correct Answer: A
