[Main Topic: Scenario-Based Design Strategy Guidance]
Feature-rich and attributed networks are used to model complex systems where nodes and links can represent various relationships and characteristics. Which two alternative network models can be used to model interactions over time or by specific relationships?
A. heterogeneous network
B. information network
C. location-aware network
D. multilayer network
E. probabilistic network
F. temporal network
Answer: D, F
????Comprehensive Explanation:
D. Multilayer Network:This model captures different types of relationships or interactions by separating them into layers. Each layer can represent a specific attribute (e.g., organizational structure, communication paths, or access levels), enabling a more granular view of network behaviors or dependencies.
F. Temporal Network:A temporal network models interactions over time by including timestamps or time intervals for each interaction or link. It’s well-suited for analyzing dynamic behaviors such as traffic flow, communication logs, or transaction timelines.
Other options:
❌A. Heterogeneous Network: Refers to networks composed of different technologies or platforms, not necessarily different types of attributes or timelines.
❌B. Information Network: This is a general term and does not specifically define a structured modeling approach for attributes or time.
❌C. Location-Aware Network: Involves geolocation or spatial data but does not inherently model time or multi-attribute structures.
❌E. Probabilistic Network: Uses probability distributions to model uncertain events, not ideal for modeling time or attributes.

[Main Topic: Business-Driven Design Approaches]
A company is assessing their technology landscape before moving to the cloud. They observe that over 5000 servers have less than 50% capacity utilization. What cloud architecture model best supports optimizing resource utilization?
A. homogenous cloud
B. heterogenous cloud
C. hybrid-private cloud
D. public cloud
Answer: D
????Comprehensive Explanation:
D. Public Cloud:Public cloud services provide elastic and scalable infrastructure. For workloads with low or variable utilization, public cloud offers pay-as-you-go models that significantly reduce the overhead of underutilized on-prem hardware. This is ideal for shifting capital expenditure (CAPEX) to operational expenditure (OPEX), achieving better cost efficiency.
Other options:
❌A. Homogenous Cloud: Not a standard term; it might imply uniform hardware/software environments, but it doesn’t address utilization.
❌B. Heterogenous Cloud: Typically used to describe mixed environments but doesn’t directly offer utilization optimization.
❌C. Hybrid-Private Cloud: Offers flexibility and data control but still often involves maintaining some level of underused on-prem resources unless carefully managed.
