1. Which statement best describes cloud computing and the role of a cloud service provider?
- A.Cloud computing delivers on-demand compute, storage, and services over the internet while the provider manages the underlying infrastructure and platform offerings.✓ Correct
- B.Cloud computing is a software license model where providers sell perpetual on-premises licenses and do not manage customer infrastructure.
- C.Cloud computing requires customers to host all hardware in their own data centers while vendors only provide consulting services for setup and maintenance.
- D.Cloud computing is exclusively a private network model where the provider only supplies hardware racks to each customer without shared services.
Explanation
Cloud providers deliver on-demand IT resources and manage infrastructure and platform services; the other options describe on-premises licensing or incorrect provider roles.
2. A company moves its web application to a managed PaaS offering. Under the shared responsibility model, which responsibility most likely shifts to the provider?
- A.The cloud provider takes responsibility for patching and securing the platform runtime and underlying host infrastructure while the customer still secures their application code and data.✓ Correct
- B.The customer no longer needs to secure application code or data because the provider assumes full responsibility for business logic and sensitive information.
- C.The provider assumes responsibility for the customer's internal network segmentation and employee access control policies inside their corporate LAN.
- D.The provider is now responsible for the customer's compliance reporting and legal liability for data breaches without customer involvement.
Explanation
PaaS providers manage and patch the platform and host infrastructure while customers retain responsibility for their application code and data; other options overstate provider responsibilities.
3. Which characteristic is a key aspect of public cloud architecture and multitenancy?
- A.Public clouds host multiple customers on shared physical resources using logical isolation, which enables economies of scale and variable resource allocation.✓ Correct
- B.Public clouds require each customer to have dedicated, single-tenant hardware to guarantee complete physical isolation for all workloads.
- C.Public clouds only provide services via private leased lines and never use the public internet for customer connectivity.
- D.Public clouds mandate that customers manage all hypervisor and physical server patching within the provider's datacenter.
Explanation
Public clouds use shared physical infrastructure with logical isolation for tenants to gain scale; other options incorrectly claim dedicated hardware or customer-managed provider infrastructure.
4. An enterprise requires strict physical isolation for highly regulated workloads. Which private cloud attribute supports that requirement?
- A.A private cloud provides single-tenant or dedicated physical resources and strong isolation controls to meet regulatory and compliance needs for sensitive workloads.✓ Correct
- B.A private cloud always means running workloads on public shared infrastructure with only virtual network segmentation for isolation.
- C.A private cloud requires using only open-source software and prohibits any vendor-managed security services for compliance reasons.
- D.A private cloud forces all costs to be charged as OpEx and disallows capital investments in hardware by the enterprise.
Explanation
Private clouds can offer dedicated physical resources and stronger isolation for regulated workloads; other options misstate private cloud characteristics or financial models.
5. A company wants to keep sensitive databases on-premises but burst analytics to the cloud during peaks. Which architecture best fits this requirement?
- A.A hybrid cloud integrates private on-premises infrastructure with public cloud resources, enabling sensitive data to stay local while non-sensitive workloads run in the public cloud for scalability.✓ Correct
- B.A hybrid cloud forces all workloads to be duplicated both on-premises and in the public cloud to ensure identical environments at all times.
- C.A hybrid cloud mandates that network traffic between on-premises and public cloud must always traverse the public internet without dedicated connectivity options.
- D.A hybrid cloud prohibits using managed cloud services for analytics and requires all analytics tooling to be self-hosted on-premises.
Explanation
Hybrid clouds let organizations keep sensitive systems on-premises while using public cloud resources for scalable tasks; other options are incorrect constraints.
