1. The ___network_______ Emulator in the hypervisor interacts with the NIC Driver in the Virtual Machine. 2. The __storge________ Emulator in the hypervisor interacts with the SCSI Driver in the Virtual Machine. 3. The hypervisor connects to the __NIC________ on the physical server to provide networking capabilities. 4. The hypervisor connects to the ___storage_______ Controller on the physical server to handle storage access. 5. Data deduplication can operate at ___byte___ level, ____block_____ level, and _file___ level, potentially reclaiming between 30 to 90 percent of storage space. 6. Which of the following best describes the purpose of data deduplication? A. To improve processing speed by duplicating data B. To replace duplicated entities with pointers to the original C. To increase the number of backups stored D. To compress files without modifying their content 7. Scenario: You are managing a virtualized environment for a company. The sales team needs their virtual machines to be accessible from external networks to host client-facing web services, while the finance team's virtual machines should remain isolated and only communicate internally within the host. Question:Which network connection type should you use for the following scenarios, and why? a. Sales Team VMs b. Finance Team VMs ( Ans at the end ) 8. True or False: Network I/O control ensures that individual VMs or groups of VMs have guaranteed bandwidth during high usage periods, even on VMware ESX. 9. What is the primary function of a virtual switch in a virtualized network? A. To directly connect virtual machines to the internet B. To manage and isolate network traffic between VMs and physical NICs C. To replace physical NICs in virtual machines D. To allow VMs to operate without IP addresses 10. Why is it recommended to isolate storage traffic from user traffic in a virtualized network? A. To prevent network congestion and improve storage performance B. To reduce the need for additional physical NICs C. To enhance VM migration speed D. To allow storage traffic to bypass the hypervisor 11. True or False:Virtual machines can support legacy peripherals like parallel and serial ports, even though these are no longer commonly offered on modern physical servers or supported by newer operating systems. 12. Which of the following is NOT true about cloning virtual machines? A. Cloning duplicates the virtual hardware and software. B. Cloning ensures the cloned VM has a unique identity automatically. C. Full clones require the same storage space as the original VM. D. Linked clones save storage space by referencing the original VM. 13. True or False: Virtual machine templates are stored in a read-only state to prevent unintended changes and are often referred to as "golden images." 14. When a snapshot is created, the original virtual machine disk is __locked_, and changes are written to a ____child___ disk. Reverting to the snapshot __erases___ the child disk, while deleting the snapshot ___merges__ the changes into the original disk. 15. Scenario: You need to perform maintenance on a virtualization host without disrupting running virtual machines or their applications. ( Ans at the end ) Question: What feature would you use to migrate running VMs to another host without interrupting user applications, and why is it important for planned downtime? 16. How does Fault Tolerance (FT) differ from High Availability (HA) in virtualization? A. FT prevents application interruptions, while HA restarts VMs after a server crash B. FT restarts VMs after a server crash, while HA prevents application interruptions. C. FT handles only planned downtime, while HA handles both planned and unplanned downtime. D. FT requires shared storage, while HA does not. 17. Consider the following statements about High Availability (HA) in virtualization: 1. Clustering links two or more physical servers via network and shared storage to provide redundancy. 2. High Availability ensures that virtual machines on a failed server continue running without any interruptions. Which of the following options is correct? A. Statement 1 is True, Statement 2 is False B. Statement 1 is False, Statement 2 is True C. Both Statements are True D. Both Statements are False 18. Virtual appliances are prebuilt and pretested _VMs__ that already contain the necessary components to deploy their application. They are faster to deploy because the entire appliance is replaced during _patching_ or updates. 19. True or False: VM-affinity ensures that two virtual machines will always run on the different hosts, while anti-affinity ensures they will always run on the same host 20. Which of the following parameters is used to control CPU and memory resources in virtual machines? A. Reservations, Allocations, Policies B. Reservations, Shares, Limits C. Limits, Allocations, Clustering D. Shares, Policies, Affinity Answer for 7 : Sales Team VMs: Use Bridged Network Connection as assigns each VM a unique IP address that is directly reachable from the external network. Finance Team VMs: Use NAT (Network Address Translation) Network Connection as it assigns each VM a unique IP address but isolates them from external access. Answer for 15 : Live migration allows the running VMs to move to another host smoothly, enabling host maintenance without disturbing the user applications, which is important for planned downtime and maintaining service continuity.
