1Which cloud service model delivers virtualized computing infrastructure (servers, storage, networking) over the internet and gives the customer control over the operating system, middleware, and applications?

A.Software as a Service (SaaS)

B.Platform as a Service (PaaS)

C.Infrastructure as a Service (IaaS)

D.Function as a Service (FaaS)

Explanation: IaaS provides raw virtualized compute, storage, and networking resources. The cloud provider manages the physical hardware and hypervisor layer; the customer is responsible for the OS, middleware, runtime, and applications. AWS EC2, Azure Virtual Machines, and GCP Compute Engine are classic IaaS examples.

2A development team wants a cloud environment where they can deploy and run their web application without managing the underlying OS patches, runtime upgrades, or server scaling. Which service model best fits this requirement?

A.Infrastructure as a Service (IaaS)

B.Platform as a Service (PaaS)

C.Software as a Service (SaaS)

D.Network as a Service (NaaS)

Explanation: PaaS delivers a managed platform — runtime, middleware, OS, and scaling are handled by the cloud provider — so developers focus solely on writing and deploying code. Google App Engine, Azure App Service, and Heroku are typical PaaS offerings.

3Which cloud deployment model is built for exclusive use by a single organization, whether hosted on-premises or by a third party, and is not shared with other tenants?

A.Public cloud

B.Community cloud

C.Hybrid cloud

D.Private cloud

Explanation: A private cloud is dedicated to one organization. Resources are not shared with external tenants, providing greater control, security, and customization. It can be located on-premises (customer-owned hardware) or hosted by a managed service provider, but the key characteristic is single-tenant exclusivity.

4An organization uses its own on-premises data center for sensitive workloads and bursts to a public cloud provider during peak demand. Which deployment model describes this architecture?

A.Private cloud

B.Community cloud

C.Hybrid cloud

D.Multi-cloud

Explanation: A hybrid cloud integrates private (on-premises) and public cloud environments linked by standardized or proprietary technology, allowing data and applications to move between them. 'Cloud bursting' — scaling peak workloads into a public cloud — is a classic hybrid cloud use case.

5Which cloud deployment model is shared exclusively among several organizations that have common concerns — such as regulatory requirements or a shared mission — rather than being open to the general public?

A.Public cloud

B.Private cloud

C.Hybrid cloud

D.Community cloud

Explanation: A community cloud is provisioned for exclusive use by a specific community of organizations that share common requirements (mission, policy, compliance, security). It may be managed by one or more of the community members or by a third party. A government-only cloud shared by multiple agencies is a typical example.

6A Type 1 hypervisor differs from a Type 2 hypervisor primarily because it:

A.Runs on top of a host operating system

B.Runs directly on the physical hardware without a host OS

C.Uses software emulation instead of hardware virtualization

D.Can only run a single virtual machine at a time

Explanation: A Type 1 (bare-metal) hypervisor runs directly on the physical server hardware without a host OS beneath it. This gives it lower overhead and better performance for enterprise and cloud workloads. VMware ESXi, Microsoft Hyper-V (when installed as a standalone hypervisor), and KVM (which replaces the Linux kernel with a hypervisor) are Type 1 examples.

7VMware ESXi is best classified as which type of hypervisor?

A.Type 2 hypervisor

B.Type 1 hypervisor

C.Container runtime

D.Paravirtualization driver

Explanation: VMware ESXi is a Type 1 bare-metal hypervisor that installs directly on server hardware. There is no host OS layer between ESXi and the physical server, which minimizes latency and maximizes resource efficiency for enterprise virtualization.

8KVM (Kernel-based Virtual Machine) is built into the Linux kernel. How does this architectural decision classify KVM?

A.Type 2 hypervisor, because Linux is the host OS

B.Container runtime, because it uses kernel namespaces

C.Type 1 hypervisor, because the Linux kernel itself becomes the hypervisor

D.Emulator, because it does not use hardware virtualization extensions

Explanation: KVM converts the Linux kernel into a bare-metal hypervisor by loading the kvm.ko kernel module. Because the hypervisor functionality is part of the kernel itself — not an application running on top of a general-purpose OS — KVM is classified as a Type 1 hypervisor, even though a Linux user space still exists for management.

9Which statement correctly distinguishes a Docker container from a virtual machine?

A.Containers include a full guest OS kernel; VMs share the host OS kernel

B.Containers share the host OS kernel; VMs include a full guest OS per instance

C.Containers require a Type 1 hypervisor; VMs run directly on hardware

D.Containers are heavier than VMs because they include hardware emulation

Explanation: Docker containers share the host OS kernel and use Linux namespaces and cgroups for isolation, making them lightweight and fast to start. Virtual machines each include a complete guest OS with its own kernel, managed by a hypervisor. This is why containers have a smaller footprint but provide weaker isolation boundaries than VMs.

10In Kubernetes, what is a Pod?

A.A physical server node in a Kubernetes cluster

B.The smallest deployable unit, consisting of one or more tightly coupled containers sharing the same network namespace

C.A Kubernetes object that load-balances traffic across multiple cluster nodes

D.A persistent storage volume attached to a cluster node

Explanation: A Pod is Kubernetes' smallest schedulable unit. It encapsulates one or more containers that share a network namespace (same IP address and port space) and optionally share storage volumes. Kubernetes schedules, scales, and restarts Pods rather than individual containers.

JNCIA-Cloud Study Tips from Top Performers

1Map each Juniper cloud product to its specific use case: vSRX for VM-based firewall/VPN, cSRX for container-native security, cRPD for routing-only containerized control plane, vMX for high-throughput virtual routing, and Contrail for SDN overlay management.

2Memorize the NIST five cloud characteristics (on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service) and know how each applies to IaaS/PaaS/SaaS.

3Learn the ETSI NFV MANO stack from top to bottom: NFVO orchestrates services → VNFM manages VNF lifecycle → VIM manages NFVI resources (OpenStack). Know what each does and does not do.

4For Kubernetes, focus on the big four objects: Pod (smallest unit), Deployment (desired state + updates), Service (stable network endpoint), and ReplicaSet (replica count). Know what each is for.

5Practice explaining the difference between Type 1 and Type 2 hypervisors, and classify KVM, ESXi, Hyper-V, VirtualBox, and VMware Workstation correctly.

6Understand public cloud connectivity options: AWS Direct Connect, Azure ExpressRoute, and GCP Cloud Interconnect all provide private circuits bypassing the internet. AWS Transit Gateway and Azure Virtual WAN simplify multi-VPC/VNet hub-and-spoke connectivity.
