A customer is looking for a reliable well-performing， cost-effective solution to a growing commercial workload.   Initially， they want to run 12 UDB partitions， each of which would need two processors and 8GB of memory.  They are looking at the p655 and want to start with three LPARS on each p655 node using a total of four nodes.   Each LPAR would need at least 4 x 6239 fibre cards and 2 x 5706 2-port 10/100/1000 Ethernet cards.   At a later date， they want to add an additional LPAR to each node to expand to a total of 16 UDB partitions. Which of the following major limitations of this solution should be mentioned to the customer？（）

• A、The p655 supports only two LPARs.
• B、The p655 supports only four LPARs.
• C、There are not enough available slots for three LPARs.
• D、There are not enough available slots for four LPARs.
