A generative model deployed on Vertex AI shows stable latency but gradually produces semantically incoherent outputs. Which architectural factor is the most plausible root cause?
GPU memory fragmentation
Concept drift between training distribution and live prompts
Network egress throttling
Tokenization mismatch at inference
In large-scale generative AI deployments, why does prompt engineering function as a quasi-architectural control mechanism?
It constrains the effective output distribution without retraining

A research group migrates from a traditional supercomputer to Aneka on commodity cloud resources. Which trade-off is most pronounced?
Accuracy versus speed
Cost elasticity versus deterministic performance
Storage capacity versus memory bandwidth
Security versus usability
In cloud-native architectures, data protection becomes harder primarily because
Storage is cheaper
Data flows dynamically across distributed services
Encryption is weak
Compliance is optional
A zero-trust architecture fundamentally changes data protection assumptions by
Trusting internal networks
Eliminating implicit trust at all layers
Centralizing authentication
Reducing encryption overhead
AI-driven anomaly detection systems in cloud security are prone to which subtle failure mode?
