QUESTION 10
A number of high priority virtual machines require significant file system access and you are trying to
decide what type of memory impact on dom0 they will have. Which two are best practices you should
consider for memory use in dom0?
A. You should always run a find command on dom0 to fill the file system buffer cache for
bestperformance.
B. You should not run a find command on dom0 as it will use up Dom0 memory and potentiallycause
double buffering with virtual machines.
C. When increasing load with additional virtual machines, you should always add more memory
todom0.
D. When increasing load with additional virtual machines, you generally wont add more memory
todom0.
Correct Answer: A,C
QUESTION 11
What two benefits can be derived from having multiple utility servers?
