1. Question 1

In which cloud service model does the provider manage application data + infrastructure + platform?

❌ PaaS
✅ SaaS
❌ CaaS
❌ IaaS

Explanation:
SaaS providers manage everything: infrastructure, platform, application, and application data.

---

2. Question 2

Where can customers deploy middleware and install applications in IaaS?

✅ Virtual Machines
❌ AI
❌ IoT
❌ Blockchain

Explanation:
IaaS VMs provide full control — OS, middleware, runtime, and apps.

3. Question 3

A concern in cloud infrastructure configuration/management:

❌ Business continuity & disaster recovery
❌ Solving complex computational problems
✅ Dependency on a third party for workload availability and performance
❌ Scaling infrastructure

Explanation:
Cloud introduces dependency on the provider’s uptime, performance, and SLAs.

---

4. Question 4

User responsibility in PaaS:

❌ Workload management
✅ Application code and its maintenance
❌ Business process systems
❌ Database management

Explanation:
PaaS abstracts OS, DB, runtime; the customer only manages code.

---

5. Question 5

PaaS capability eliminating the need to integrate disparate components:

❌ Rapid deployment
❌ Runtime environment
✅ APIs for services
❌ Business analytics services

Explanation:
APIs unify services like messaging, identity, storage, analytics — reducing integration complexity.

---

6. Question 6

Characteristic of SaaS:

❌ Users maintain infra/code
❌ SaaS apps are free
✅ Applications reside on a remote cloud network
❌ Users see only their own app

Explanation:
SaaS apps run in the provider’s cloud and are accessed via web/clients.

---

7. Question 7

Users’ role in a public cloud:

❌ Users own storage
❌ Users manage servers
❌ Users maintain platform
✅ Users don’t own the servers their applications run on

Explanation:
Public cloud = provider-owned infrastructure.

---

8. Question 8

Feature of a private cloud:

✅ Application portability
❌ External computing resources
❌ Limited security
❌ Uncontrolled access

Explanation:
Private clouds emphasize control, customization, and portability across internal systems.

---

9. Question 9

Best model for highly sensitive + mission-critical + unpredictable workloads:

❌ Private cloud
❌ On-premises
✅ Hybrid Cloud
❌ Public cloud

Explanation:
Hybrid gives security of private cloud + elasticity of public cloud (bursting, scaling).

---

10. Question 10

Meaning of “cloud bursting”:

✅ Use public cloud temporarily during demand spikes and return to private cloud afterward
❌ Modernizing core systems
❌ Moving apps/data between on-prem and cloud
❌ Pay-as-you-go environments

Explanation:
Cloud bursting is a hybrid cloud strategy for unpredictable spikes.
