1. What steps are required when doing a live migration between servers in a VMM environment? 2. Which type of VMM can support a guest that is itself a VMM? 3. What benefit do VMMs bring to system administration? . Fle systems are generally designed using a layered approach for each item below, dentify the file system layer that will oUTPUT this command a. "read drivel, cylinder 72. track 2, sector 10, into memory location 1060. b. "retrieve logical block 63 C. "retrieve physical block 123 5. What function does each of these serve: a. Buffer b. Cache 6. What information is stored in the FCB? . Aprocess closes a file. What is the impact on the System-wide-Open-File Table? 8. What is a Page Fault? What causes it? What does the OS do about it (5 steps)? 9. What is a modify (dirty) bit? What purpose does it serve? 10. Using the LRU Page Replacement Algorithm determine how many pages faults will occur for the following reference string a 8 0230 40534 0 11.Assuming a system has 86 available frames and there are two processes P1 with size 20 and P2 with size 100, set up the equations to determine how many frames will be assigned to P1 and P2 using the Proportional Allocation frame all scheme For what Operating System feature are the Base Register and the Limit Register required? What value does each register contain? How are those values used? 12. ddress binding of instructions and data to memory addresses can happen at three different stages. Name the three stages. Identify the binding that is used by most general-purpose operating systems 13. A 14.A memory manager currently has a list of unallocated blocks of 7KB, 15KB, 20KB, 12KB, and 14KB blocks. If a process arrives requiring 13KB. Show how the process will be accommodated for each of the dynamic storage allocation strategies below a. Best-Fit b. Worst-Fit c. First-Fit 15. Define: a. External Fragmentation b. Internal Fragmentation 16. Suppose that the operating system uses two internal tables to keep track of open files. Process A has two files open and process B has three files open. Two files are shared between the two processes. How many entries are in the per-process table of process A, the per-process table of process B, and the system-wide tables respectively? a. 5,5,5 b. 2, 3, 3 c. 2, 3, 5
