Which cloud deployment model gives a telecom operator the most control over data sovereignty and regulatory compliance?
Answer: Private cloud
Private cloud keeps infrastructure dedicated to a single organization, providing maximum control over data location and compliance.
In telecom cloud architectures, what does the term 'Network Function Virtualization Infrastructure' (NFVI) refer to?
Answer: The underlying hardware and software that hosts VNFs
NFVI is the collection of physical and virtual resources (compute, storage, networking) on which VNFs are deployed and executed.
A telecom company wants to migrate its BSS/OSS to the cloud while keeping core network functions on-premises. Which cloud model best describes this architecture?
Answer: Hybrid cloud
Hybrid cloud combines on-premises (private) infrastructure with public cloud resources, allowing selective workload placement.
What is the primary purpose of a Kubernetes namespace in a telecom cloud-native deployment?
Answer: To logically partition cluster resources among different teams or services
Kubernetes namespaces provide logical isolation and resource scoping within a single cluster, enabling multi-tenancy.
Which cloud storage type is most appropriate for a telecom CDN storing large media files that are accessed frequently?
Answer: Object storage (hot tier)
Hot-tier object storage offers high throughput and low latency for frequently accessed large binary objects like media files.
What is 'cloud bursting' in the context of telecom infrastructure?
Answer: Automatically scaling workloads from private to public cloud during demand spikes
Cloud bursting allows a private cloud to offload peak traffic automatically to public cloud resources when local capacity is exhausted.
In telecom cloud infrastructure, which metric best measures the efficiency of compute resource utilization?
Answer: Server CPU utilization percentage
CPU utilization percentage directly reflects how efficiently compute resources are being used relative to provisioned capacity.
