1. Which of the following best describes the difference between cloud computing and fog
computing?
A) Cloud computing processes data near loT devices, while fog computing processes data only in
centralized data centers.
B) Cloud computing offers distributed processing across gateways, while fog computing performs
computation only in the cloud core.
C) Cloud computing relies on centralized data centers for computation, whereas fog computing
distributes processing closer to end devices through intermediate nodes.
D) Cloud computing is used only for storage, while fog computing is used only for real-time analytics.
Answer : c
2. An autonomous vehicle that must instantly detect obstacles and apply brakes should primarily rely on:
A) Cloud computing
B) Fog computing
C) Edge computing
D) Centralized data warehouse
Answer : c
3. In terms of physical proximity to end devices (closest to farthest), which order is correct?
A) Cloud → Fog → Edge
B) Edge → Fog → Cloud
C) Fog → Edge → Cloud
D) Edge → Cloud → Fog
Answer : b
4. Which resource management strategy is most important to prevent overload when many edge devices send data to nearby fog nodes?
A) Increasing storage capacity at a single fog node
B) Static task allocation
C) Load balancing across fog nodes
D) Sending all data directly to the cloud
Answer : c
5. Which statement best explains task offloading decisions in a fog-edge-cloud architecture?
A) All tasks must first be processed in the cloud before reaching fog or edge
B) Edge devices always offload tasks to the cloud, bypassing fog
C) Time-critical tasks are handled at edge/fog, while computation-intensive but delay-tolerant
tasks are sent to the cloud
D) Fog nodes only store data and do not participate in computation
Answer : c
6. Which factor most strongly influences whether a task should be executed at the edge instead of the cloud?
A) Data archival requirements
B) Latency sensitivity of the application
C) Cloud storage capacity
D) Size of historical datasets
Answer : b
7. Which metric is most directly optimized when moving computation from cloud to fog
nodes?
A) Disk storage size
B) Network latency
C) Data encryption level
D) Database consistency
Answer : b
8. Which issue is most critical for maintaining trust among Cloud Service Providers (CSPs) in a cloud federation?
A) Uniform hardware configuration across all CSPs
B) Standardized pricing models only
C) Federated identity management and secure SLA enforcement
D) Centralized ownership of all federated data centers
Answer : c
9. Which architectural mechanism most enables interoperability in a cloud federation?
A) Proprietary APIs unique to each CSP
B) Closed resource management policies
C) Standardized interfaces and open protocols (e.g., REST, OCCI, CIMI)
D) Centralized control by a single dominant CSP
Answer : c
10. Which scenario best justifies the need for workload migration in a hybrid cloud federation?
A) When all workloads have identical security and compliance requirements
B) When private cloud resources are underutilized and public cloud is idle
C) When sensitive workloads must remain on private infrastructure, but burst workloads require
additional public cloud capacity
D) When interoperability between clouds is intentionally restricted
