(a) Public cloud
(b) Private cloud
(c) Community cloud
(d) Hybrid cloud

8. A startup company needs to deploy a customer relationship management system quickly without purchasing servers or managing infrastructure. The solution should provide ready-to-use software accessible via web browser. Which cloud service model should they choose?

(b) DaaS (Desktop as a Service)
(c) SaaS (Software as a Service)
(d) PaaS (Platform as a Service)

9. A virtual machine running Ubuntu Server is experiencing extremely slow disk performance. The VM is stored on a SATA SSD host drive but configured with IDE virtual disk controllers. What change would MOST likely improve performance?
(a) Increase the virtual machine's CPU allocation
(b) Change the virtual disk controller to SCSI or NVMe
(c) Add more virtual RAM to the guest OS
(d) Enable disk compression on the host

10. A software development team needs a cloud environment to build, test, and deploy custom applications without managing operating systems or server hardware. They require control over application code and runtime environments. Which service model fits these requirements?
(a) SaaS
(b) PaaS
(c) IaaS
(d) DaaS

11. An administrator notices that a Hyper-V host server with 32GB of physical RAM is running slowly despite only three VMs being active. Each VM is allocated 8GB of RAM but typically uses only 3GB. Which Hyper-V feature should be enabled to optimize memory usage?
(a) Virtual machine checkpoints
(b) Dynamic Memory
(c) Enhanced Session Mode
(d) Production checkpoints

12. A company uses Amazon Web Services for email hosting, Microsoft Azure for file storage, and on-premises servers for their ERP system. What type of cloud deployment model is this organization using?
(a) Multi-cloud
(b) Public cloud
(c) Hybrid cloud
(d) Community cloud

13. A technician attempts to create a new virtual machine in VirtualBox but receives an error: "VT-x is disabled in the BIOS for all CPU modes." The system runs Windows 11 on an AMD Ryzen 7 processor. What should the technician do FIRST?
(a) Disable Windows Defender to allow virtualization
(b) Access BIOS/UEFI and enable AMD-V (SVM Mode)
(c) Reinstall VirtualBox with administrator privileges
(d) Upgrade to VirtualBox Pro version

14. Which virtualization component is responsible for allocating physical hardware resources to multiple virtual machines and isolating them from each other?
(a) Virtual switch
(b) Guest operating system
(c) Hypervisor
(d) Virtual NIC

15. A cloud service provider guarantees 99.99% uptime in their SLA. A customer experiences a 50-minute outage during a calendar month with 30 days. Has the provider met their SLA commitment?
(a) Yes, because 50 minutes is within the 99.99% uptime threshold
(b) No, because 99.99% uptime allows only 4.32 minutes of downtime per month
(c) Yes, because SLA only applies to business hours
(d) No, because any outage violates the SLA regardless of duration

16. An administrator needs to provide 50 remote employees with identical desktop environments including Windows 10, Microsoft Office, and custom business applications. The solution must allow centralized management and access from various devices. Which technology is MOST appropriate?
(a) VPN with local installations
(b) VDI (Virtual Desktop Infrastructure)
(c) Software distribution via Group Policy
(d) Terminal Services with application streaming

(a) Public cloud
(b) Hybrid cloud
(c) Community cloud
(d) Private cloud

18. A virtual machine's .vmdk file has grown to 500GB despite the guest OS showing only 180GB of actual data usage. The VM has been running for six months with frequent application installations and removals. What process would reclaim the unused space?
