CSA Virtualization & Cloud Services 2 — Questions and Answers
Question 1: A customer wants to run multiple isolated workloads on a single physical server without buying additional hardware. Which technology best addresses this need?
- Network-attached storage (NAS)
- Server virtualization (Correct answer)
- Content delivery network (CDN)
- Load balancing appliance
Correct answer: Server virtualization
Server virtualization allows multiple isolated virtual machines to run on one physical host, maximizing hardware utilization.
Question 2: Which cloud deployment model gives a company the most control over its infrastructure while still using cloud technology?
- Public cloud
- Community cloud
- Hybrid cloud
- Private cloud (Correct answer)
Correct answer: Private cloud
A private cloud is dedicated to a single organization, offering maximum control over security, configurations, and resources.
Question 3: A prospect asks about a service where the provider manages the operating system, middleware, and runtime, and the customer only deploys their application code. This describes which cloud model?
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS) (Correct answer)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
Correct answer: Platform as a Service (PaaS)
PaaS provides a managed platform (OS, runtime, middleware) so developers focus solely on writing and deploying application code.
Question 4: What is the primary advantage of cloud elasticity for a retail business that experiences seasonal traffic spikes?
- Permanent capacity increase at no extra cost
- Ability to scale resources up or down based on demand (Correct answer)
- Fixed monthly pricing regardless of usage
- Automatic security patch management
Correct answer: Ability to scale resources up or down based on demand
Cloud elasticity lets businesses automatically scale compute resources up during peaks and down during slow periods, paying only for what they use.
Question 5: A hypervisor that runs directly on the physical hardware without a host operating system is called a:
- Type 2 hypervisor
- Hosted hypervisor
- Type 1 hypervisor (Correct answer)
- Container runtime
Correct answer: Type 1 hypervisor
A Type 1 (bare-metal) hypervisor runs directly on hardware, offering better performance and security than Type 2 hypervisors.
Question 6: Which cloud pricing model best suits a customer with unpredictable, sporadic workloads that cannot tolerate interruptions?
- Reserved instances with upfront payment
- Spot or preemptible instances
- On-demand instances (Correct answer)
- Dedicated hosts with annual commitment
Correct answer: On-demand instances
On-demand instances provide pay-as-you-go pricing with no interruption risk, making them ideal for unpredictable workloads.
Question 7: When a sales rep positions a hybrid cloud solution, which customer pain point is most directly addressed?
- Need to eliminate all on-premises hardware immediately
- Desire to keep sensitive data on-premises while leveraging public cloud scalability (Correct answer)
- Requirement for zero capital expenditure
- Want to standardize on a single public cloud vendor
Correct answer: Desire to keep sensitive data on-premises while leveraging public cloud scalability
Hybrid cloud lets organizations keep regulated or sensitive data on-premises while using public cloud resources for scalable, less-sensitive workloads.
