Examine this IORM plan:

Which two are true concerning this plan?

• A.I/Os from the finance database are guaranteed to get 45% of the I/O bandwidth if the demand is at least 60% of the maximum I/O rate of the cell, but may get 100% of the I/O bandwidth if no other databases are performing I/O to the cell.
• B.If I/Os come from the HR database only, then they may get up to 10% of the I/O bandwidth on the cell.
• C.I/Os from the finance database are guaranteed to get a minimum of 45% of the I/O bandwidth if the demand exists, and a maximum of 60% of the I/O bandwidth even if no other databases are doing I/O to the cell, and the demand from the finance database exceeds 60% of the maximum I/O rate of the cell.
• D.The Finance database can use at least 45%, but never more than 60%, of the total Flash Cache capacity.
• E.If I/Os come from the HR database only, then they may get up to 100% of the I/O bandwidth on the cell.

Which two are true about the allocation of I/O resources by IORM within the CELLSRV process?

• A.If two consumer groups C and D in the PROD database get 10% and 15% respectively, of resource allocation, then the percentage of I/O resource would be the same if they still got 10% and 15% respectively, and were remapped to a different category by the DBA, provided that the category plans and the interdatabase plans are unchanged.
• B.Log Writer I/O and Control File I/O are always prioritized over all user I/O.
• C.If two consumer groups A and B in the PROD database get 10% and 15% respectively, of resource allocation, then the percentage of I/O resource would be the same if they got 20% and 30% respectively, provided that the category plans and interdatabase plans are unchanged, and consumer groups A and B are still mapped to the same category.
• D.Database Writer I/O is always prioritized over all user I/O.
• E.If two consumer groups P and Q in the PROD database get 20% and 10% respectively of resource allocation, then the percentage of I/O resource would be the same if they got 10% and 5% respectively, and the interdatabase plan has changed, provided that the category plan is unchanged, and consumer groups P and Q are still mapped to the same categories.
