Q: 1 With respect to hypervisors, following statements are given below:
(P) Runs on host machine physical hardware
(Q) Hosted hypervisor
(R) Runs on the operating system of physical host machine
(S) Bare metal hypervisor
Which of the following is correct match?
Type-1 Hypervisor : (P) and (Q)
Type-2 Hypervisor : (R) and (S)
Type-1 Hypervisor : (P) and (S)
Type-2 Hypervisor : (Q) and (R)
Type-1 Hypervisor : (R) and (S)
Type-2 Hypervisor : (P) and (Q)
Type-1 Hypervisor : (R) and (Q)
Type-2 Hypervisor : (P) and (S)
[ Option B ]
A hypervisor is software that allows multiple virtual machines (VMs) to run on a single physical machine. There are two main types of hypervisors: Type-1 (Bare Metal) and Type-2 (Hosted).
| HYPERVISOR TYPE | CHARACTERISTICS |
|---|---|
| Type-1 Hypervisor (Bare Metal) | Runs directly on the physical hardware of the host machine without a host operating system. |
| Type-2 Hypervisor (Hosted) | Runs on top of an existing operating system of the host machine. |
Q: 2 Which cloud computing model delivers applications over the internet, allowing users to access services like word processing and CRM without installing them locally?
Infrastructure as a Service (IaaS)
Software as a Service (SaaS)
Platform as a Service (PaaS)
Hardware as a Service (HaaS)
[ Option B ]
In cloud computing, different service models provide varying levels of resources and management. Software as a Service (SaaS) is the model that delivers applications over the internet, allowing users to access software such as word processors, Customer Relationship Management (CRM) tools, or email clients without installing them locally.
| CLOUD SERVICE MODEL | DESCRIPTION |
|---|---|
| Infrastructure as a Service (IaaS) | Provides virtualized computing resources over the internet, including servers, storage, and networking. Users manage OS, applications, and data while the provider manages hardware. |
| Platform as a Service (PaaS) | Provides a platform for developers to build, test, and deploy applications without worrying about underlying infrastructure. Includes OS, middleware, and runtime environment. |
| Software as a Service (SaaS) | Delivers software applications over the internet. Users access applications via web browsers or thin clients without installing locally. Provider manages everything from infrastructure to software updates. |
Q: 3 What does “elasticity” in cloud computing refer to?
Ability to scale up and scale down of compute resources
Parallel execution of jobs
High availability of systems
Minimum response time
[ Option A ]
In cloud computing, Elasticity refers to the ability of a system to automatically increase or decrease computing resources such as CPU, memory, or storage according to workload demand.
When demand increases, resources can be SCALED UP, and when demand decreases, resources can be SCALED DOWN.
Q: 4 Which of the following is not an example of cloud storage?
Drop Box
One Drive
Google Drive
LX Drive
[ Option D ]
Cloud Storage is an online storage system that requires internet connectivity to store, access, and manage data on remote servers maintained by third-party providers.
| Cloud Storage Service | Provider |
|---|---|
| Google Drive | |
| OneDrive | Microsoft |
| Dropbox | Dropbox Inc |
| iCloud | Apple |
| Box | Box Inc |
| AWS S3 | Amazon |
| Mega | Mega Limited |
| pCloud | pCloud AG |
| IBM Cloud Object Storage | IBM |
