  What are the two valid settings for fractional reserve? (Choose two.)

  A. 100%

  B. 20%

  C. 0%

  D. 50%

  Correct Answer: AC

  The fractional reserve setting is expressed as a percentage; the only valid values are 0 and 100 percent. You use the vol options command to set fractional reserve. Reference: https://library.netapp.com/ecmdocs/ ECMP1368845/html/GUID-596042AF- 8E9C-4187-969C-633DFDD5A936.html

• Question 213:

  When creating a data aggregate, what is the default minimum number of disks for RAID4 and RAID-DP?

  A. 5 for RAID4 and 9 for RAID-DP

  B. 4 for RAID4 and 7 for RAID-DP

  C. 3 for RAID4 and 5 for RAID-DP

  D. 2 for RAID4 and 3 for RAID-DP

  Correct Answer: D

  If a root volume exists as a traditional volume, it can be a stand-alone RAID4 or RAID-DP volume. RAID4 requires a minimum of two disks and can protect against single-disk failures. RAID-DP, the default RAID type, requires a minimum of three disks and can protect against double-disk failures. Using RAID-DP for the root aggregate is recommended.
