A Type 1 hypervisor differs from a Type 2 hypervisor in which fundamental way?
Answer: Type 1 runs directly on host hardware; Type 2 runs on top of a host OS
Type 1 (bare-metal) hypervisors run directly on hardware without an underlying OS for better performance and security, while Type 2 (hosted) hypervisors run as applications on top of a host OS.
What is the primary security concern introduced by multitenancy in cloud computing environments?
Answer: Potential for data leakage or unauthorized access between co-located tenant workloads
Multitenancy introduces the risk that tenant data or workloads could be exposed to other tenants through misconfigurations, virtualization vulnerabilities, or side-channel attacks on shared infrastructure.
NIST SP 800-145 defines cloud computing with five essential characteristics, three service models, and how many deployment models?
Answer: Four
NIST SP 800-145 defines four cloud deployment models: private cloud, community cloud, public cloud, and hybrid cloud.
Which NIST cloud computing characteristic describes the ability of cloud resources to be provisioned and released rapidly to scale elastically with demand?
Answer: Rapid elasticity
Rapid elasticity allows cloud resources to be provisioned and released quickly—automatically in some cases—to scale with demand, appearing unlimited to the consumer.
In a Software as a Service (SaaS) deployment, which area does the cloud customer retain primary responsibility for?
Answer: User identity, access management, and data stored in the application
In SaaS, the customer's responsibility is primarily limited to managing user access, identity provisioning, and the data they input and store in the application.
What is the key architectural difference between containers and virtual machines (VMs)?
Answer: Containers share the host OS kernel; VMs include a complete guest OS per instance
Containers share the host OS kernel and isolate only the application and its dependencies, making them more lightweight, while VMs include a full guest OS per instance.
What does the term 'cloud bursting' describe in a hybrid cloud architecture?
Answer: The automatic overflow of workloads from a private cloud to a public cloud during demand spikes
Cloud bursting allows applications to run in a private cloud and automatically extend to public cloud resources when demand exceeds private cloud capacity, enabling cost-effective scalability.
