CTE Cloud Infrastructure 2 — Questions and Answers
Question 1: Which cloud deployment model gives a telecom operator the most control over data sovereignty and regulatory compliance?
- Public cloud
- Private cloud (Correct answer)
- Community cloud
- Hybrid cloud
Correct answer: Private cloud
Private cloud keeps infrastructure dedicated to a single organization, providing maximum control over data location and compliance.
Question 2: In telecom cloud architectures, what does the term 'Network Function Virtualization Infrastructure' (NFVI) refer to?
- The set of virtual network functions running on the cloud
- The underlying hardware and software that hosts VNFs (Correct answer)
- The orchestration layer managing VNF lifecycle
- The management and network orchestration (MANO) framework
Correct 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.
Question 3: 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?
- Multi-cloud
- Edge cloud
- Hybrid cloud (Correct answer)
- Private cloud
Correct answer: Hybrid cloud
Hybrid cloud combines on-premises (private) infrastructure with public cloud resources, allowing selective workload placement.
Question 4: What is the primary purpose of a Kubernetes namespace in a telecom cloud-native deployment?
- To provide network isolation between pods
- To logically partition cluster resources among different teams or services (Correct answer)
- To define the physical node assignment for workloads
- To manage persistent storage volumes
Correct 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.
Question 5: Which cloud storage type is most appropriate for a telecom CDN storing large media files that are accessed frequently?
- Archive storage (cold tier)
- Object storage (hot tier) (Correct answer)
- Block storage
- File storage
Correct answer: Object storage (hot tier)
Hot-tier object storage offers high throughput and low latency for frequently accessed large binary objects like media files.
Question 6: What is 'cloud bursting' in the context of telecom infrastructure?
- Exceeding cloud provider SLA thresholds
- Automatically scaling workloads from private to public cloud during demand spikes (Correct answer)
- A security breach caused by misconfigured cloud APIs
- Overprovisioning cloud resources beyond actual need
Correct 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.
Question 7: In telecom cloud infrastructure, which metric best measures the efficiency of compute resource utilization?
- Network throughput in Gbps
- Server CPU utilization percentage (Correct answer)
- Power Usage Effectiveness (PUE)
- Mean Time Between Failures (MTBF)
Correct answer: Server CPU utilization percentage
CPU utilization percentage directly reflects how efficiently compute resources are being used relative to provisioned capacity.
