Actual exam question for IBM's C9030-644 exam

Question #: 1
Topic #: 4

A customer is upgrading a zEC12 to a z13 and has FICON Express8 channels installed to support their 2Gb I/O devices, which must also be connected to the z13. They are migrating to the z13 to take advantage of larger memory configurations supported on the z13 for DB2.

In order to take advantage of LPARs which can support memory sizes greater than 2TB, what must be configured on this upgrade?

AReplace the FICON Express8 with FICON Express16S to provide the customer with faster transfer rates.

BReplace the FICON Express8 with FICON Express 16S and make sure they have a converter to step down the 16 Gb. to 2 Gb.

CCarry forward FICON Express8 channel cards to support the 2Gb devices.

DUpgrade FICON Express8 to FICON express8S to eliminate the old eight-slot I/O drawer.

Show Suggested Answer

Suggested Answer: D

The FICON Express8S feature is exclusively in the PCIe I/O drawer. Each of the two independent ports is capable of 2 Gbps, 4 Gbps, or 8 Gbps. The link speed depends on the capability of the attached switch or device. The link speed is auto-negotiated, point-to-point, and is transparent to users and applications.
