Public vs private vs hybrid vs community — community cloud is shared by orgs in same industry (rare on exam but know it).

PaaS = dev platform without managing OS/runtime. Azure App Service, Elastic Beanstalk — you code, they run the stack.

VMware Workstation on Win11 = Type 2 hosted hypervisor. ESXi on a server = Type 1 bare metal.

Vendor-hosted email where you only manage users = SaaS. M365 is the classic example they want.
Client hypervisor on a tech's laptop for testing = Type 2. Don't pick Type 1 just because it sounds 'more professional'.
IaaS = you patch the VM OS, provider runs the metal. EC2, Azure VMs, GCE.
Containers share the host OS kernel — lighter than full VMs. Docker/Kubernetes basics are fair game on A+ now.
Hybrid = sensitive data stays private, burst/scheduling to public. Not the same as multi-cloud.

Catalog listing of the 5 preview questions for this quiz.
Question 1
An enterprise is running a VMware vSphere environment. Multiple VMs share the same physical server. One VM begins consuming 95% of the physical CPU resources, causing other VMs to slow significantly. Which VMware feature limits CPU consumption per VM?
Explanation
VMware vSphere allows administrators to set CPU reservations (guaranteed minimum), shares (relative priority), and limits (maximum CPU usage) per VM to prevent any single VM from monopolizing physical host resources.
Question 2
A company uses containers to deploy its microservices application. How do containers differ from traditional virtual machines?
Explanation
Containers share the host OS kernel and package only the application and its dependencies, making them lightweight and fast to start. VMs include a full OS instance (guest OS), making them more isolated but heavier on resources.
Question 3
A technician needs to provide network connectivity to virtual machines running on a Type 1 hypervisor. Which component provides network switching capabilities within the virtualization platform?
Explanation
A virtual switch (vSwitch) is a software-based network switch created within the hypervisor. It allows VMs to communicate with each other and with the physical network through the host's physical NICs, providing VLAN support, port groups, and traffic policies.
Question 4
A hospital wants to keep patient data on-premises for compliance while using public cloud resources for non-sensitive workloads like scheduling and HR. What deployment model does this describe?
Explanation
A hybrid cloud combines private cloud/on-premises infrastructure with public cloud resources, allowing data and applications to be shared between them. This enables compliance-sensitive workloads to remain on-premises while leveraging public cloud scalability.
Question 5
A technician is setting up a VM and needs to allocate storage. They configure a 100GB virtual disk but want it to only use actual space as data is written (not pre-allocate the full 100GB immediately). Which disk provisioning type should they choose?
Explanation
Thin provisioning allocates virtual disk space on-demand as data is actually written, rather than reserving the full capacity upfront. This conserves physical storage. Thick provisioning reserves all space immediately, ensuring performance but consuming storage immediately.
Resource pooling + rapid elasticity + measured service — know the NIST cloud characteristics.
