QUESTION 237:
Mem.SamplePeriod (Select Appropriate definition)
A. Limits the maximum amount of memory that can be reclaimed from any virtual machine using vmmemctl,based on a percentage of its configured memory size. Specifying 0 disables reclamation via vmmemctl for all virtual machines. Default is 65
B. Specifies the total system-wide rate at which memory should be scanned for transparent page sharing opportunities. The rate is specified as the number of pages to scan per second. Defaults to 200 pages/sec. Default is 200
C. Controls the rate at which the system scans memory to identify opportunities for sharing memory. Units are pages per second. Default 50
D. Specifies the idle memory tax rate, as a percentage. This tax effectively charges virtual machines more for idle memory than for memory they are actively using. A tax rate of 0 percent defines an allocation policy that ignores working sets and allocates memory strictly based on shares. A high tax rate results in an allocation policy that allows idle memory to be reallocated away from virtual machines that are unproductively hoarding it. Default 75
E. Specifies the periodic time interval, measured in seconds of the virtual machine's execution time, over which memory activity is monitored to estimate working set sizes. Default 60
F. Specifies the periodic time interval, in seconds, for automatic memory reallocations. Reallocations are also triggered by significant changes in the amount of free memory. Default 15
Answer: E
